Notläsning på gitarr : En studie om vilka strategier och metoder gitarrister på gymnasiets estetiska program använder i en notläsningsbunden kontext. / Score-reading on guitar : A study of what strategies and methods guitarists at the Swedish aestethics program use in a specific score-reading taskNilsson, Arvid January 2016 (has links)
This paper aims (i) to investigate what strategies and methods guitar students at the Swedish aestethic programme use when they play notes after a specific score , and (ii) to find out what they think is easy or hard about reading music. The method of this paper is an experiment combined with an interview with 5 students. The purpose of the interview is to find out what the students think they use for methods and strategies when they play guitar after a score.The purpose of the experiment is to see how they solve the task to play after a notepaper and to compare what they think they do to what they actually are doing. The theory I am using in this paper is Donald Schöns and Bengt Molanders theory about “knowledge in action”. The results show that the many students use different strategies and methods to solve the notebound task. The strategies and methods they use are: a) playing within a so called “box”, b) the use of octaves to find the right tones, c) the usage of open strings, and d) memorizing techniques. They also find it easier to read notes that are close to each other and therefore they think it is harder to read notes that are further away from each other. They also find it harder to read notes that are not in the scale.

A HACCP study on yoghurt manufactureHoolasi, Kasthurie January 2005 (has links)
Thesis (M.Tech.: Quality)-Dept. of Operations & Quality Management, Durban Institute of Technology, 2005
xiii, 68 leaves / The increasing awareness and demand of consumers for safe and high quality food have lead many companies to undertake a comprehensive evaluation and reorganisation of their food control systems in order to improve efficiency, rationalisation of human resources and to harmonise approaches. This evaluation in food control systems has resulted towards the necessity to shift from the traditional approach that relied heavily on end-product sampling and inspection and to move towards the implementation of a preventative safety and quality approach, based on risk analysis and on the principles of the hazard analysis critical control
point (HACCP) system. Yoghurt is the most popular fermented milk world-wide; the estimated annual consumption in South Africa amounts to nearly 67 million litres. The aim of this study was to implement a HACCP program in a commercial yoghurt factory and then to evaluate the program during certain critical stages of the manufacturing process.

Generic Metadata Handling in Scientific Data Life CyclesGrunzke, Richard 11 May 2016 (has links) (PDF)
Scientific data life cycles define how data is created, handled, accessed, and analyzed by users. Such data life cycles become increasingly sophisticated as the sciences they deal with become more and more demanding and complex with the coming advent of exascale data and computing. The overarching data life cycle management background includes multiple abstraction categories with data sources, data and metadata management, computing and workflow management, security, data sinks, and methods on how to enable utilization. Challenges in this context are manifold. One is to hide the complexity from the user and to enable seamlessness in using resources to usability and efficiency. Another one is to enable generic metadata management that is not restricted to one use case but can be adapted with limited effort to further ones.
Metadata management is essential to enable scientists to save time by avoiding the need for manually keeping track of data, meaning for example by its content and location. As the number of files grows into the millions, managing data without metadata becomes increasingly difficult. Thus, the solution is to employ metadata management to enable the organization of data based on information about it. Previously, use cases tended to only support highly specific or no metadata management at all. Now, a generic metadata management concept is available that can be used to efficiently integrate metadata capabilities with use cases.
The concept was implemented within the MoSGrid data life cycle that enables molecular simulations on distributed HPC-enabled data and computing infrastructures. The implementation enables easy-to-use and effective metadata management. Automated extraction, annotation, and indexing of metadata was designed, developed, integrated, and search capabilities provided via a seamless user interface. Further analysis runs can be directly started based on search results. A complete evaluation of the concept both in general and along the example implementation is presented. In conclusion, generic metadata management concept advances the state of the art in scientific date life cycle management.

A MODULAR APPROACH TO LANDSAT 7 GROUND PROCESSINGMah, G. R., Pater, R., Alberts, K., O’Brien, M., Senden, T. 10 1900 (has links)
International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / Current Landsat 7 processing is based on a single-string, multifunction approach. A follow-on system has been designed that repartitions functions across multiple hardware platforms to provide increased flexibility and support for additional missions. Downlink bit stream acquisition has been moved to lower cost systems functioning as “capture appliances” with high-speed network interconnections to Level 0 processing on generic compute servers. This decouples serial data stream acquisition from the processing system to allow the addition or replacement of compute servers, without the reintegration of specialized high-speed capture hardware. Moreover, it also allows the easy integration of new systems and missions without extensive system redesign or additional software.

Application of Van-der-Waals forces in micro-material handlingMatope, Stephen 12 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2012. / This doctoral dissertation focuses on the application of Van-der-Waals’ forces in micromaterial
handling. A micro-material handling system consists of four main elements, which
include: the micro-gripper, the micro-workpart, the picking up position and the placement
position. The scientific theoretical frameworks of Van-der-Waals’ forces, presented by Van
der Waals, Hamaker, London, Lifshitz, Israelachvilli, Parsegian, Rumpf and Rabinovich, are
employed in exploring the extent to which these forces could be applied in a micromanufacturing
situation. Engineering theoretical frameworks presented by Fearing,
Bohringer, Sitti, Feddema, Arai and Fukuda, are employed in order to provide an in-depth
synthesis of the application of Van-der-Waals’ forces in micro-material handling. An
empirical or pragmatic methodology was adopted in the research.
The Electron Beam Evaporation (e-beam) method was used in generating interactive surfaces
of uniform surface roughness values. E-beam depositions of copper, aluminum and silver on
silicon substrates were developed. The deposition rates were in the range of 0.6 – 1.2
Angstrom/s, at an average vacuum pressure of 2 x 10-6 mbar. The topographies were analysed
and characterised using an Atomic Force Microscope and the corresponding rms surface
roughness values were obtained. The Rumpf-Rabinovich equation, which gives the
relationship of the exerted Van-der-Waals’ forces and the rms surface roughness values, is
used to numerically model the results. In the final synthesis it is observed that the e-beam
depositions of copper are generally suited for the pick-up position. Aluminum is suited for the
micro-gripper and silver is suited for the placement position in an optimised micro-material
handling system.
Another Atomic Force Microscope was used in order to validate the numerically modelled
results of the exerted Van- der-Waals’ forces. The aim was to measure the magnitude of Vander-
Waals’ forces exerted by the e-beam depositions and to evaluate their applicability in
micro-material handling operations. The measurements proved that Van-der-Waals’ forces
exerted by the samples could be used for micro-material handling purposes on condition that
they exceeded the weight of the micro-part being handled.
Three fundamental parameters, ie: material type, geometrical configuration and surface
topography were used to develop strategies of manipulation of micro-materials by Van-der-
Waals’ forces. The first strategy was based on the material type variation of the interactive surfaces in a micro-material handling operation. This strategy hinged on the fact that materials
have different Hamaker coefficients, which resulted in them experiencing a specific Van-der-
Waals’ forces’ intensity during handling. The second strategy utilised variation in the
geometrical configuration of the interacting surfaces. The guiding principle in this case was
that, the larger the contact area was, the greater the exerted Van-der-Waals’ forces would be
In the analytical modelling of Van-der-Waals’ forces with reference to geometrical
configuration, a flat surface was found to exert more force than other configurations. The
application of the design, for purposes of manufacturing and assembling (DFMA) criteria,
also proved that flat interactive surfaces have high design efficiency. The third strategy was
based on surface roughness. The rougher the topography of a given surface was, the lesser the
Van-der-Waals’ forces exerted were. It was synthesised that in order for a pick-transfer-place
cycle to be realised, the root-mean-square (rms) interactive surface roughness values of the
micro-part (including the picking position, the micro-gripper, and the placement position)
should decrease successively. Hybrid strategies were also identified in this research in order
to deal with some complex cases. The hybrids combined at least two of the aforementioned
strategies.

Maturity indexing, pharmacological properties and postharvest performance of pomegranate fruit grown in South AfricaFawole, Olaniyi Amos 12 1900 (has links)
Thesis (PhD(Agric))--Stellenbosch University, 2013. / ENGLISH ABSTRACT: The development and application of science-based tools for determining optimum fruit
maturity and postharvest handling protocols to maintain quality and reduce losses during
postharvest handling and marketing is essential to maintain the competitiveness of the emerging
pomegranate industry in South Africa. Currently, there are no quality standards for the South
African pomegranate industry, neither is there a general consensus on the optimal harvest
maturity indices for fruit cultivars. These information are important to ensure the delivery of
good quality fruit to consumers, particularly for long supply chains. The overall aims of this
study were (a) to develop science-based management tools for determining optimum maturity
indices and storage performance of pomegranate fruit cultivars grown in South Africa, and (b) to
characterise the physico-chemical and pharmacological properties of selected cultivars relevant
to postharvest handling and industrial applications. In Section II, seasonal studies on pomegranate (‘Baghwa’ and ‘Ruby’) fruit growth and
the evolution of maturity indices during development were conducted. Significant increases in
total soluble solids (TSS), sugars (glucose and fructose) and anthocyanin composition, coupled
with significant decline in titratable acidity (TA), organic acids and total phenolics (TP) occurred
with advancing fruit maturity. Fruit at advanced maturity stages were characterized by intense
pigmentation of peel and aril, which coincided with maximum accumulation of anthocyanins.
Among all the major maturity indices investigated, TSS, BrimA and anthocyanins did not show
significant (p<0.05) seasonal variability, and strong correlations were found among the indices.
In combination, these indices accounted for fruit juice sugar content, acidity and colour and
could serve as reliable markers to determine optimal maturity for both pomegranate cultivars.
The studies in Section III focused on characterization of postharvest quality including
nutritional, medicinal and antioxidant properties of fruit parts. Quality attributes of eight
commercial cultivars were analysed by cluster analysis, which enabled the cultivars to be
separated into two clusters (cluster 1 = ‘Ruby’, ‘Arakta’ and ‘Ganesh’; cluster 2 = ‘Bhagwa’,
‘Acco’ and ‘Herskawitz’) and two ungrouped cultivars (‘Molla de Elche’ and ‘Wonderful’)
based on important quality attributes (size, texture, colour, soluble solids, acidity, juiciness and
phenolics). Furthermore, pomegranate fruit peel extracts were studied to highlight their potential
for value-adding in pharmaceutical and other industrial applications. The results showed that fruit peels of the investigated cultivars possess strong antibacterial, antioxidant and antityrosinase
activities, and hence could be exploited as potential sources of natural antimicrobial
and antioxidant agents, as well as a potential tyrosinase inhibitor.
The research reported in Section IV investigated the effects of harvest maturity and
storage conditions on postharvest quality and nutritional value of ‘Bhagwa’ and ‘Ruby’ cultivars.
Fruit harvested at commercial maturity were stored at 5±0.3°C, 7±0.5°C and 10±0.4°C with
92±3% RH and at room temperature (20±2.2°C, 65±5.5% RH) for 16 weeks. Fruit physiological
responses and quality were affected by storage condition, with the maximum levels of respiration
occurring at higher temperature and extended storage duration. Fruit colour and antioxidant
capacity varied slightly among storage temperatures, with total soluble solids and titratable
acidity decreasing gradually over time at different temperatures. Considering that fruit stored at
5°C and 92% RH had significantly reduced weight loss, low incidence of physiological disorders
and best results in maintaining flavour attributes (TSS and TA, TSS:TA ratio), the investigated
cultivars may be stored at 5°C and >92% RH for 8 - 12 weeks. In paper 9 (Section IV), the research investigated the relationships between instrumental
and sensory measurements of pomegranate fruit at different harvest maturities during storage and
shelf life. Mature ‘Bhagwa’ fruit harvested at different times could not be discriminated by
sensory attributes assessed by a trained panel. However, TSS (R2 = 0.677) and juice content (R2
= 0.512) were the two most decisive quality attributes at shelf life related to harvest maturity
status. For ‘Ruby’, however, a combination of instrumental and sensory attributes appeared to be
influential in discriminating mature fruit harvested at different times, with TSS:TA ratio being
the most decisive (R2 = 0.654) in distinguishing different fruit harvests, followed by sweet taste
(R2 = 0.474) and hue angle (R2 = 0.431). The results showed that to ensure the best post-storage
quality of ‘Bhagwa’, the optimum harvest maturity was between 167 - 175 DAFB (H2 and H3)
when fruit reached maximum TSS level (>16°Brix; H3) and juice content (>65 mL/100 g aril;
H2). However, for ‘Ruby’, this study indicated that the optimum harvest date was at 143 DAFB
(H2) when TSS:TA ratio was >55, which coincided with significantly higher sensory rating for
sweet taste after shelf life of fruit at H2 than H1 and H3, respectively.
The results from this thesis provide new understanding and better insights on fruit
characteristics of major pomegranate cultivars grown in South Africa. Overall, the study
provides new knowledge on science-based tools for assessing fruit readiness for harvest as well as storage conditions to maintain fruit postharvest quality and reduce losses. It also provides
scientific information on phytochemical contents and antioxidant compounds in fruit to promote
value-adding of pomegranate as a good raw material with potential applications in health food
products and other industrial applications such as pharmaceuticals and cosmetics. / AFRIKAANSE OPSOMMING; Die ontwikkeling en toepassing van wetenskapgegronde instrumente vir die bepaling
van optimale vrugrypheid en naoes-hanteringsprotokolle om gedurende die naoes-hantering en
-bemarking van vrugte gehalte te behou en verliese te verminder, is noodsaaklik om die
mededingendheid van die ontluikende granaatbedryf in Suid-Afrika te verseker. Tans is daar
nie enige gehaltestandaarde vir die Suid-Afrikaanse granaatbedryf óf algemene
eenstemmigheid oor die optimale oesrypheidsaanwysers vir vrugtekultivars nie. Hierdie
inligting is belangrik om die naoes-lewering van uithalervrugte aan verbruikers te verseker,
veral vir lang verskaffingskettings. Die oorkoepelende doelwitte van hierdie studie was (a) om
wetenskapgegronde bestuursinstrumente te ontwikkel vir die vasstelling van optimale
rypheidsaanwysers en bergingsprestasie van granaatkultivars wat in Suid-Afrika verbou word,
en (b) om die fisiko-chemiese eienskappe en farmakologiese kenmerke van gekose kultivars te
tipeer.
In deel II is seisoenale studies oor granaatgroei en die ontwikkeling van rypheidsaanwysers
gedurende groei onderneem. Namate vrugte ryp geword het, is beduidende toenames in totale
oplosbare vaste stowwe (TSS), suikers (glukose en fruktose) en antosianien-samestelling
opgemerk, sowel as ’n beduidende afname in titreerbare suur (TA), organiese suur en totale fenol
(TP). Vrugte in gevorderde stadia van rypheid is gekenmerk deur intense pigmentasie van die skil
en aril, wat met maksimum opbou van antosianien verband gehou het. Van ál die belangrike
rypheidsaanwysers wat ondersoek is, het TSS, BrimA en antosianien onbeduidende (p<0.05)
seisoenale veranderlikheid getoon, en is sterk verbande tussen die aanwysers opgemerk.
Gesamentlik sou die aanwysers kon rekenskap gee van sapsuikerinhoud, -suurgehalte én -kleur, en
sou dit dus as betroubare rypheidsmerkers kon dien om optimale rypheid vir albei granaatkultivars
te bepaal. Die studies in deel III het gekonsentreer op die tipering van die naoes-kenmerke, onder
meer die voedings-, medisinale en antioksidant-kenmerke van vrugtedele. Kenmerke van agt
kommersiële kultivars is deur middel van groepsontleding bestudeer, waarvolgens die kultivars
op grond van belangrike kenmerke (grootte, tekstuur, kleur, oplosbare vaste stowwe, suurgehalte,
sappigheid en fenol) in twee groepe (groep 1 = ‘Ruby’, ‘Arakta’ en ‘Ganesh’; groep 2 =
‘Bhagwa’, ‘Acco’ en ‘Herskawitz’) en twee niegegroepeerde kultivars (‘Molla de Elche’ en ‘Wonderful’) ingedeel is. Ten einde die toegevoegde waarde van granaatskille vir farmaseutiese
en kosmetiese doeleindes te bevorder, is skilekstrakte ook bestudeer. Die resultate toon dat die
vrugteskille van die bestudeerde kultivars oor sterk antibakteriese, antioksidant- en antitirosinase-
eienskappe beskik. Daarom kan die skil van die granaatkultivars as moontlike bron
van natuurlike antimikrobiese en antioksidant-agense sowel as ’n moontlike tirosinase-inhibitor
ontgin word.
Die navorsing in deel IV het ondersoek ingestel na die uitwerking van oesrypheid en
bergingsomstandighede op die naoes-gehalte en -voedingswaarde van die kultivars ‘Bhagwa’ en
‘Ruby’. Vrugte wat op kommersiële rypheid geoes is, is vir 16 weke by 5±0.3 °C, 7±0.5 °C en
10±0.4 °C met 92±3% RH, sowel as by kamertemperatuur (20±2.2 °C, 65±5.5% RH) geberg.
Die bergingsomstandighede het die fisiologiese reaksies en gehalte van die vrugte beïnvloed:
Maksimum vlakke van respirasie het teen hoër temperature en met verlengde berging
voorgekom. Die kleur en antioksidantvermoë van die vrugte het effens tussen
bergingstemperature verskil, en totale oplosbare vaste stowwe en titreerbare suur het mettertyd
geleidelik by verskillende temperature afgeneem. Gedagtig daaraan dat die vrugte wat teen 5 °C
en 92% RH geberg is beduidend minder gewigsverlies, ’n lae voorkoms van fisiologiese
afwykings en die beste resultate in blywende geurkenmerke (TSS en TA, TSS:TA-verhouding)
getoon het, kan die bestudeerde kultivars vir 8 tot 12 weke teen 5 °C en >92% RH geberg word
(navorsingstuk 8). In navorsingstuk 9 (deel IV) is daar ondersoek ingestel na die verhouding tussen
instrument- en sintuiglike metings van granate in verskillende stadia van oesrypheid gedurende
berging en raklewe. Geen verskil in sintuiglike kenmerke kon bespeur word by ryp ‘Bhagwa’-
vrugte wat op verskillende tye geoes is nie. Tog was TSS (R2 = 0.677) en sapinhoud (R2 = 0.512)
die twee bepalendste gehaltekenmerke wat betref oesrypheidstatus gedurende raklewe. By
‘Ruby’ kon ’n kombinasie van instrument- en sintuiglike kenmerke egter wél tussen stadia van
oesrypheid onderskei, met die TSS:TA-verhouding die bepalendste (R2 = 0.654) in die
onderskeid tussen verskillende vrugteoeste, gevolg deur ’n soet smaak (R2 = 0.474) en
skakeringshoek (R2 = 0.431). Die resultate toon dat die beste nabergingsgehalte vir ‘Bhagwa’
verkry word by ’n optimale oesrypheid van 167–175 DAFB (H2 en H3), wanneer vrugte die
maksimum TSS-vlak (>16°Brix; H3) en sapinhoud (>65 mL/100 g aril; H2) bereik het. Vir
‘Ruby’ dui hierdie studie op ’n optimale oesdatum van 143 DAFB (H2) met ’n TSS:TA-verhouding van >55, wat verband gehou het met ’n beduidend hoër telling vir soet smaak by H2
eerder as by H1 en H3 ná raklewe.
Die resultate van hierdie tesis bied ’n beter begrip van, en insig in, die vrugtekenmerke van
granaatkultivars wat in Suid-Afrika verbou word. Oor die algemeen bied die studie wetenskaplike
inligting om moontlik die toegevoegde waarde van granate as ’n goeie bron van minerale elemente
sowel as farmaseutiese, kosmetiese en antioksidant-verbindings te bevorder. Dit bied ook kennis
oor die ontwikkeling van wetenskapgegronde instrumente vir die vasstelling van optimale
vrugrypheid en naoes-hanteringsprotokolle om gedurende die naoes-hantering en -bemarking van
granate vruggehalte te behou en verliese te verminder.

The design principles and success factors for the operation of cross dock facilities in grocery and retail supply chainsVogt, John Joseph 12 1900 (has links)
Dissertation (PhD)--Stellenbosch, 2004. / ENGLISH ABSTRACT: The dissertation reflects the research done on the design principles and success factors
for the operation of cross dock facilities in grocery and retail supply chains.
The cross dock is a particular facility in the supply chain where goods are received
from suppliers, sorted without storage of the goods, and then efficiently moved to
downstream customers.
Cross docks are not a new operation. However, the use in high volume grocery and
retail operational capabilities is poorly understood and is not uniquely defined. The
problem is that cross docks are often seen as extensions of warehouses. The same
personnel, systems and processes are applied and the efficiency potential of the cross
dock is not achieved.
Warehouses are orientated towards storing the full range of product and allowing the
pick to be done from this storage buffer to provide any or all of these products to a
customer. Cross docks will only handle products that are used in larger quantities and
that are sent to most, if not all, the customers. The cross dock is therefore distinct and
very different from the traditional warehouse.
The published research tends to focus on the technical aspects of the cross dock
layout. This research is primarily in the scheduling of the trucks into the yard of the
facility; the allocation of trucks to specific doors of the facility; and the allocation of
doors to receiving and despatch functions within the facility. Very little information or
research reflects the design principles and success factors for the cross dock and its
supply chain. The only classification of the cross dock in the literature is whether the
barcode is added to the item before or after receipt at the cross dock.
For this research work a literature survey was conducted and five major operations
were reviewed, in South Africa and the USA. The research empirically drew logical
conclusions, which were tested in the operations and found to be correct. This allowed
the design principles and success factors to be determined for a successful cross dock.
The research extends the knowledge of the cross dock operation and design: -
• A new classification for the feasible types of cross docks in the supply chain
was developed. Three factors are shown to be of primary importance: -
o Where in the supply chain the identification of specific items for a
customer is done;
o Where the sort is done for the items to be delivered to a customer; and
o Whether the supplier is providing one product or multiple products to
the sort.
From these three factors, eight potential classifications could be defined.
However, only three practical types of cross dock can be determined from
these eight alternatives. These are named in this research as Cross Dock
Managed Load (CML); Joint Managed Load (JML); and the Supplier
Managed Load (SML). The cross dock is far more effective than the warehouse when the total work
(excluding inventory) is considered. The earlier in the supply chain the
product is identified for the use of the entire downstream supply chain, the
more effective will be the total supply chain. Thus the greatest supply chain
effectiveness possible is with the SML, then the JML and finally the CML.
• The operation of a cross dock is very similar to a continuous manufacturing
process. There is no buffer of stock to decouple the inbound and outbound
processes, and the operation takes place in a restricted area. However, in the
retail chain, the workload alters with different orders and different days. Daily
load differences vary by as much as 90%. This results in vastly different
workloads and variations of throughput. This is similar to a batch operation
with highly variable workloads between batches. The literature recommends
the use of Just in Time (JIT) practice for cross docks. This is inappropriate as
its primary requirements are continuous full volume operation and continuous
small improvements to achieve a balanced operation. The most appropriate
method of process improvement is the Theory of Constraints (TO C) and not
JlT.
• The management must have a detailed, disciplined approach. This implies
standardised methods of operation, and a high degree of training. Equally there
is the requirement for a special type of personnel to operate the cross dock.
These operating personnel must be able to operate with precision (i.e. very low
error rates) and be able to maintain this capability for continuous periods.
• The systems required for a successful operation must include the capabilities
of Yard Management, WMS for cross docking, Order Management with
Advanced Shipping Notice (ASN) capability and Track and Trace across the
supply chain. The items need to be identified by a barcode. The information
required on the barcode will be determined by. the information systems
capability of the least advanced service provider in the supply chain. If this
service provider can receive and transmit all the data required for the supply
chain from and to the other members, then the barcode need only be an
identification number of the specific item. The data pertaining to the items is
then passed from system to system in the supply chain. If data movement is
not possible between all the parties in the entire supply chain, then the barcode
must contain the information that will identify the item, the origin and the final
delivery destination. If the items are delivered as part of a consignment, a
further quantum of information is required to identify the total number of
items in the consignment and the specific item within the consignment.
• The research shows that the overall capability of the cross dock or its
maximum capacity is the combination of the capability of the personnel and
the cross dock design. Restrictions on either the personnel capability or the
design of the cross dock, or both, severely reduces the effectiveness of the
cross dock.
• The previous research on the sequence of allocation of trucks to specific doors
within the cross dock can be enhanced with a new sequencing method. The
new method allocates the transport, in sequence of arrival, to the open door that either numrruses the walk distance in the facility; or maximises the
completion of the consignments in order to minimise the area required to build
the consignments; or a combination of both. The choice of these will be
determined by the constraints imposed by the design of the building. This is an
important extension as this ties the supply chain into the cross dock operation,
rather than looking at the cross dock in isolation as has been done in this
previous research.
• The factors that influence the design of a cross dock as to its size, shape,
number of doors, and the specifically required additional areas, is defined in
detail. The principles of these factors and their inter-relationships and
dependencies are used in a detailed design for a cross dock. The detailed
design process is set out from data analysis through to the actual size
calculations and layouts. Measurements of walk distance and sort movement
are used to determine the most effective design. The design is shown to be
considerably more effective than the older designs.
This work has significantly extended the research on the design principles and success
factors for implementation of cross docks in retail supply chains. The research derives
a unique new classification for cross docks. An improvement is made to existing
research on the allocation of the transport to particular doors in the cross dock. The
operation, management and personnel are shown to require specific characteristics.
The information systems required for effective cross docks is determined and defined.
The identification of the individual items by barcode and the information required
within the barcode depending on the information sophistication of the service
providers in the supply chain is defined. A detail process to design a cross dock is
evolved, with the full knowledge of the factors that must be considered and their interrelationships.
Measurements to determine the effectiveness of the design are used to
choose the most appropriate design. All these are then synthesised into a new design,
which is far more effective than any of the other designs researched. The design
process will produce a very effective cross dock as has been demonstrated with a new
facility. / AFRIKAANSE OPSOMMING: geen opsomming
