Decision-making framework for inventory management of spare parts in capital-intensive industries

Du Toit, Deirdre 12 1900 (has links)
Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Effective management of spare parts inventory is essential to companies because it influences inventory costs and asset utilization. The vast and diverse portfolio of spare parts, intermittent demand patterns and contradicting objectives between departments are examples of some of the factors that complicate Spare Parts Management (SPM). Managers of spare parts are faced with trade-off decisions between risk and cost on a daily basis. These decisions include, amongst many, determining appropriate stock levels and order frequencies. Despite the importance of SPM, decisions are however often made intuitively in practice with little factual support, and the decision-making process is commonly constrained within departmental silos. Even though there is a large body of academic knowledge on this topic, practical applications of spare parts inventory solutions lag behind theoretical studies. The majority of studies in literature focus on single components of SPM, such as demand forecasting and parts classification, whereas fewer studies consider the decision-making process itself. This study proposes a decision-making framework for spare parts inventory management. The framework is based on a wide-ranging literature review that focuses on capturing the essence of Spare Parts Management (SPM), but also acknowledges the interconnectedness of the problem. Therefore, core inventory management principles, as well as closely related topics such as Supply Chain Management (SCM) and Physical Asset Management (PAM), are studied in the context of spare parts. The broad scope of the literature study leads to a holistic approach to the problem and prevents sub-optimization. The proposed framework condenses principles from various fields of study (SCM, PAM, Classification and Inventory Management) into a stepwise methodology presented as a decision-making framework. The objective of the framework is to provide managers with a structured process, based on factual information, to enable better decision-making in the field. Furthermore, the framework aims to capture the fundamentals of SPM in a simplistic manner to ease the adoption of the framework in practice. A case study is conducted in the South African mining industry to validate the framework. The case study demonstrates that the framework is practical, provides structured guidance, and assists managers to make trade-off decisions in managing spare parts inventory. / AFRIKAANSE OPSOMMING: Effektiewe voorraadbestuur van onderdele is belangrik vir maatskappye omdat dit voorraadkoste en die benutting van bates beïnvloed. Die bestuur van onderdele is ’n komplekse probleem. Ondermeer is die portefeulje van onderdele items breed en divers, die vraagpatrone sporadies en word die voorraadvlakke geaffekteer deur kontrasterende doelwitte tussen verskillende departemente. Bestuurders van onderdele word daagliks gekonfronteer met besluite rakende risiko’s en kostes, soos om toepaslike voorraadvlakke te bepaal en om te besluit wanneer om bestellings te plaas. Hierdie besluite word dikwels intuïtief geneem met min feitelike ondersteuning en insette in die besluitnemingsproses word gereeld beperk tot sekere departemente. Ten spyte van die geweldige akademiese belang in die onderwerp, is daar min suksesvolle praktiese toepassings. Die meerderheid van studies in die literatuur fokus op spesifieke elemente van onderdele bestuur, soos vooruitskatting en klassifisering van parte, terwyl minder op die besluitnemingsproses konsentreer. Hierdie studie stel ’n besluitnemingsraamwerk vir die bestuur van onderdele voorraad voor. Die raamwerk is gegrond op ’n deeglike literatuurstudie wat die essensie van onderdele bestuur ondersoek, maar ook die interverbondenheid van die probleem in ag neem. Voorraadbestuurbeginsels en verwante onderwerpe soos Voorsieningskettingbestuur en Fisiese Batebestuur word dus bespreek. Die breë omvang van die literatuurstudie lei tot ’n holistiese benadering wat sub-optimering van die probleem voorkom. Die voorgestelde raamwerk som beginsels uit verskillende relevante studievelde op in ’n stapsgewyse metode wat voorgestel word as ’n besluitnemingsraamwerk. Die doel van die raamwerk is om bestuurders te voorsien met ’n gestruktureerde proses, gebaseer op feitelike inligting, om besluitneming in die veld te verbeter. Verder poog die raamwerk om die fundamentele konsepte in voorraadbestuur vas te vang in ’n eenvoudige manier sodat die raamwerk maklik geïmplementeer kan word in die praktyk. Die voorgestelde raamwerk is gevalideer deur middel van ’n gevallestudie in die Suid-Afrikaanse mynbedryf. Die gevallestudie toon dat die voorgestelde raamwerk prakties is, die besluitnemingsproses op ’n gestruktureerde wyse lei, en bestuurders help om beter, ingeligte besluite te neem.

The hidden costs of automotive commodities procured from the People’s Republic of China

Boshoff, Oliza 03 1900 (has links)
Thesis (MComm)--Stellenbosch University, 2008. / ENGLISH ABSTRACT: Globalization has shifted to a level where market competition is tougher. Therefore, multinational companies focus on cutting cost along the company’s supply chain with heavy scrutiny on procurement. Developing countries have become very attractive from which to strategically procure commodities because of low cost labour, especially from the People’s Republic of China. The business complexity, ethics and current market situation in China are often too modestly emphasized. Yet, these elements have a significant impact on the sourcing decision because it indirectly influences the total landed cost of a commodity but is not taken into account. Therefore, the total landed cost on which sourcing decisions are made, does not reflect the actual total landed cost of a commodity. In many cases multinational companies sourcing from China do not realise the impact of the hidden cost involved and do not reach the expected cost savings as calculated. The purpose of this study is to explore why more attention must be paid to hidden cost when automotive commodities are procured from China. This, as well as the research methodology used in order to obtain the data, is explained in chapter one. Chapter two of this thesis illustrates the change in a company’s supply chain and discusses this in a global sourcing context. The sourcing commodity, which is the point of focus in this study, is automotive commodities sourced from China and is discussed in chapter three. Based on China’s increased presence in global sourcing of automotive commodities, chapter four focuses on China’s integration into the global supply chain. The influential factors that have an impact (hidden cost) on the actual landed cost of commodities sourced from China are described in chapter five and identified as guanxi, indirect business logistic obstacles, quality of goods and supply, management, the labour market and training, and Intellectual Property Rights (IPR). In chapter six the influential factors, as described in chapter five, are analysed through a case study of Daimler Chrysler China Limited. Chapter seven is a comparative study of Japan’s miracle economy from 1960-1980 and the current economic trends in China to determine whether it will be feasible to procure automotive commodities from China in the future with regards to the economic indicators. / AFRIKAANSE OPSOMMING: Globalisering het verskuif na ʼn vlak waar mark kompetisie meer gekonsentreerd is. Daarom fokus multinasionale maatskappye ernstig daarop om kostes langs die aanvoerketting van die maatskappy te verminder deur te konsentreer op die aanskaffingsproses. Ontwikkelende lande het uiters aanloklik geword as bestemming in die strategiese aanskaffingsproses van goedere weens lae arbeidskoste, veral vanaf Sjina. Tans word die besigheidskompleksiteit, etiek en die markkondisie in Sjina meestal onderbeklemtoon. Daarenteen het die faktore ‘n gewigtige impak op die aanskaffingsbesluit omdat dit die totale koste by aankoms indirek beïnvloed. Gevolglik reflekteer die totale koste by aankoms, waarop aanskaffigsbesluite gegrond word, nie die werklike koste van aankoms van goedere nie. In menige gevalle behaal multinasionale maatskappye nie die verwagte kostebesparing soos bereken vir goedere wat vanaf Sjina aangeskaf word nie omdat die multinasionale maatskappye onbewus is van die impak wat die versteekte koste op die totale koste by aankoms het. Die doel van hierdie studie is ‘n ondersoek na die redes waarom daar meer beklemtoning moet wees op versteekte koste wanneer goedere uit Sjina aangeskaf word. Dit, sowel as die navorsingmetodes wat gebruik is om die inligting vir die studie in te win en akkuraat deur te gee, word verduidelik in hoofstuk een. Hoofstuk twee bespreek die verandering in 'n maatskappy se aanvoerketting in ʼn globale aanskaffingskonteks. Hoofstuk drie fokus op redes vir Sjina se toenemende verteenwoordige rol in die globale aanskaffing van goedere en op die aanskaffing van motorvoertuigparte uit Sjina. Met betrekking tot die globale aanskaffing van goedere word die integrasie van Sjina in die globale aanskaffingsketting in hoofstuk vier bespreek. Die beïnvloedende faktore wat 'n impak (versteekte koste) op die werklike koste by aankoms van die motorvoertuigparte wat aangeskaf word vanaf Sjina het, word bespreek in hoofstuk vyf en geïdentifiseer as guanxi, indirekte besigheidslogistiek hindernisse, die kwaliteit van goedere en die aanskaffing daarvan, bestuur in Sjina, die Sjinese arbeidsmark en opleiding in die werksplek, en intellektuele eiendomsreg. In hoofstuk ses word die beïnvloedende faktore (soos bespreek in hoofstuk vyf) geanaliseer deur ʼn gevalle studie van Daimler Chrysler Sjina Beperk. Hoofstuk sewe is ʼn vergelykende studie tussen Japan se wonder ekonomie van 1960-1980 en die huidige ekonomiese tendens in Sjina om te bepaal hetsy dit moontlik sal wees om motorvoertuigparte aan te skaf vanaf Sjina in die toekoms met betrekking tot die ekonomiese indikatore.

In this context, organizational innovation, which has the organizational culture as one of its main determinants, it is a key pillar of support competitiveness. Thus, this work is a multicases study in five large suppliers companies of auto parts of the metropolitan area of Sorocaba, aimed to analyze the practices of organizational innovation, and identify the factors related to the organizational culture of these companies are the key to the organizational innovation. As result, it was found that the adoption of organizational innovation practices is due to isomorphism in the automotive industries, but the organizational culture focused on innovation is essential for the occurrence of organizational innovation, and features such as financial (reward system, financial resources), organizational architecture (market orientation, mission, value and leadership), management tools (support innovation, teamwork, acceptance of risk and error tolerance, creativity, communication and management systems) are fundamentals. As factors that hinder organizational innovation were basically found problems related to people as: outgoing employees, lack of discipline, motivation, overwork, predesigned concepts, difficult to accept changes and unhappiness. The centralization of power, lack of autonomy and authoritarian leadership were also mentioned as inhibitors to the occurrence of organizational innovation. / Com a crise que vem passando a indústria automotiva, devido à redução de demanda no ano de 2015, torna-se necessário que as empresas do setor de autopeças passem por diversas mudanças para continuarem competitivas. Nesse contexto, a inovação organizacional, que tem a cultura organizacional como um dos seus principais determinantes, torna-se um pilar fundamental de sustentação da competitividade. Assim, esse trabalho, um estudo multicasos realizado em cinco empresas de grande porte fornecedoras de autopeças da região metropolitana de Sorocaba, teve como objetivo analisar as práticas da inovação organizacional, além de identificar os fatores relacionados à cultura organizacional dessas empresas que são determinantes à inovação organizacional. Como resultado encontrou-se que a adoção de práticas de inovação organizacional ocorre devido ao isomorfismo nas indústrias automotivas, porém a cultura organizacional voltada à inovação é imprescindível para a ocorrência de inovação organizacional, e características como recursos financeiros (sistema de recompensas, recursos financeiro), arquitetura organizacional (orientação para mercado, missão, valor e liderança), ferramentas gerenciais (suporte à inovação, trabalho em equipe, aceitação ao risco e tolerância ao erro, criatividade, comunicação e sistemas de gestão) são fundamentais. Como fatores que dificultam a inovação organizacional foram encontrados basicamente problemas relacionados aos recursos humanos como: saída de funcionários,falta de disciplina, motivação, sobrecarga, conceitos pré-concebidos, dificuldades para aceitar mudanças e insatisfação. A centralização de poder, a falta de autonomia e liderança autoritária também foram citados como inibidores a ocorrência da inovação organizacional.

Approches scientifiques et technologiques du frittage et de l'assemblage de matériaux métalliques par SPS / Scientific and technological approaches for sintering and joining of metallic materials by SPS

Naïmi, Foad 26 November 2013 (has links)
La technique de frittage flash (communément appelée Spark Plasma Sintering, SPS) suscite un engouement au niveau mondial. Ce procédé permet la densification de poudres à des vitesses généralement 10 à 100 fois plus élevées que celles des techniques de frittage traditionnelles. Il permet la synthèse de matériaux massifs innovants et originaux, à microstructures contrôlées, de formes complexes et de grandes dimensions. Cependant, la maîtrise du changement d’échelle et de l’homogénéité microstructurale des pièces obtenues par ce procédé nécessite une parfaite connaissance technique des équipements de frittage flash pour limiter notamment les gradients thermiques. La modélisation est une aide précieuse pour aboutir à l’amélioration de cette maîtrise. Une autre potentialité de cette technologie, l’assemblage de métaux, sans apport de matière, permet de répondre à des sollicitations industrielles pour lesquelles cette technique offre une solution alternative intéressante aux procédés d’assemblage actuels. Des aspects technologiques restent, toutefois, à maîtriser pour aller vers la réalisation d’assemblages de bonne qualité. / The flash sintering technique (commonly known as spark plasma sintering, SPS) generates a craze worldwide. This process allows a powder densification from speeds generally 10 to 100 times higher than those of the traditional sintering techniques. In addition, this allows the synthesis of innovative and original dense materials, with a controlled microstructure, complex shapes and, sometimes large sizes. However, the control of scaling and microstructure homogeneity of parts obtained by such a process requires a perfect knowledge of technical equipment including flash sintering to reduce thermal gradients. Modeling is a valuable aid to achieve the improvement of its control. Another potentiality of this technology, the welding of metal without matter, throught industrial demands offers an attractive alternative method to classical welding methods. Technological aspects remain, however, to master to go towards achieving good multi-materials.

Performance Editions of Three Works for Winds by Gyorgy Druschetzky

McDannald, Brandon K. 08 1900 (has links)
Gyorgy Druschetzky was a noted Czech composer of Harmoniemusik, who wrote more than 150 partitas and serenades, along with at least thirty-two other selections for larger wind groups. This is in addition to twenty-seven symphonies, eleven concertos (most for wind instruments), two fantasias, forty-seven string quartets, two operas, a ballet that is lost, and other miscellaneous chamber music for various combinations of wind/string instruments. Three of his works for winds have existed only in manuscript form since their composition: Concerto in E-flat pour 2 clarinett en B, 2 cors en E-flat, 2 fagott; Overture to Mozart's Die Zauberflöte; and Partitta a la camera a corno di bassetto primo, secondo, terzo, due corno di caccia, due fagotti. These works remain remarkably interesting to modern ears and deserve to be heard in the twenty-first century. Along with a brief examination of Druschetzky's life and how it figures into the history of Harmoniemusik, this work presents each piece edited into a modern performance edition.

Oration, Concerto Elegiaco by Frank Bridge: A Practical Guide for Performance

Yoo, Kyungjin 08 1900 (has links)
English composer Frank Bridge (1879-1941) is well known as Benjamin Britten's teacher and to a lesser degree for his chamber music. Because his mature creative period occurred between the First and Second World War, his works were not well studied or performed until the 1970s, well after his death. This dissertation discusses Bridge's life and his music, how World War I affected in this work, and specifically the work Oration Concerto Elagiaco. Oration is considered historically in terms of its meaning and delayed premiere. Additionally, the work's fantasy arch form, Bridge's signature compositional style, and the character of each section is discussed. Finally, this dissertation provides a practical guide to the work, providing practice and performance suggestions for the numerous complex and technically challenging portions of the concerto.

Managing space in forward pick areas of warehouses for small parts

Subramanian, Sriram 13 January 2014 (has links)
Many high-volume warehouses for small parts such as pharmaceuticals, cosmetics and office supplies seek to improve efficiency by creating forward pick areas in which many popular products are stored in a small area that is replenished from reserve storage. This thesis addresses the question of how to stock forward pick areas to maximum benefit by answering two key, inter-related decisions that have been called Assignment-Allocation. The assignment question asks which SKUs should be stored in the forward pick area? And the allocation question asks how much space should be allocated to each SKU? We show fast, simple, near-optimal algorithms to answer these questions in a variety of circumstances. To allocate space to SKUS, we introduce a Powers of Two allocation scheme designed to simplify shelf management. In addition, we present a ranking-based algorithm to assign SKUs and allocate space among multiple forward pick areas. We show that a similar algorithm that accounts for constraints on congestion and workload within the forward pick area. We also show how to determine the optimal assignment for warehouses with one or more forward pick areas that allocate space in ways that are common in practice. Warehouses frequently use the 80-20 rule to manage SKUs based on their popularity. We examine empirical data from thirty warehouses and analyze whether the power law distribution is a suitable fit. We test the hypothesis that the power law fits of warehouses in similar industries are themselves similar. We review explanations for why power laws arise in other settings and identify those that are plausible in the warehouse setting.

Study on Preventive Replacement and Reordering of Spare Parts Experiencing On-Shelf Deterioration

Luo, Hongwei January 2016 (has links)
High availability of a system can be achieved by performing timely replacement of degraded or failed components. To this end, spare parts are expected to be available and reordered when needed. It is not uncommon that spare parts may deteriorate on the shelf because of their physical characteristics and/or the imperfect storage and transportation conditions. Such phenomena will affect the reliability of spare parts and the availability of the system. In this dissertation, we first focus on a system with single critical operating component and one unit of deteriorating spare part. For such a system, to ensure the system availability and cost efficiency, making a joint decision on component replacement and reordering time is of vital importance. In particular, we study both failure-switching and preventive-switching strategies, where cumulative damage is considered for the spare part switching from its in-stock to operating conditions. To determine the corresponding optimal component replacement and reordering policies, the long-run average costs are minimized under a fixed lead time. It is expected that the work will benefit quite a few industry sectors, such as mining, oil and gas, and defense, where the operation of systems heavily relies on capital-intensive components. To advance the research a step further, we have relaxed the system with only a single operating component to a more complex system with multiple components. In addition, we have eliminated the limitations on the order quantity and inventory capacity. To capture the on-shelf part deterioration, a two-phase deteriorating process is adopted, for which the first phase is from the spare's new arrival to the identification of its degradation, and the second phase is the period thereafter but before the unit fails. Based on the parts' degradation states, we introduce two different replacement strategies for the spare consumption, i.e., the Degraded-First strategy and the New-First strategy. Because of the random nature of component failures and on-shelf deterioration, stochastic cost models for both DF and NF strategies are derived. With the objective of cost reduction through coordinating the inventory and maintenance policies, an enumeration algorithm with stochastic dynamic programming is employed for finding the joint optimal solution over a finite time horizon. Numerical experiments are conducted to study the impacts of these two strategies on the operation costs, and the analysis of key parameters that affect the optimal solutions is also carried out in the numerical study. The joint policies of our interest focus on both replacement and reordering of spare parts, which are more realistic and complex than those policies handling maintenance and spare parts inventory control separately. In particular: When the maintenance planning and inventory control strategy are jointly optimized, we consider the spare parts inventory experiencing on-shelf deterioration, which has not been well studied in the related literature. When dealing with a system carrying only one spare part, the impact of on-shelf deterioration of the spare part on its remaining operational lifetime is explicitly dealt with and described by the Cumulative Exposure (CE) model. For the extended model for a multi-component system, we make an early attempt to adopt a two-phase process to take into account on-shelf degradation of parts. The issues in the degradation-level-based ordering of spare parts in the multi-component system are also discussed. Several integrated cost models are developed in both systems and are used to determine the optimal replacement and reordering decisions with the objective of minimizing the expected long-run cost rate over an infinite/finite horizon.

'n Historiese ondersoek na die aard van enkele aktrises se vertolking van broekrolle en 'n kreatiewe verkenning van geslagsverruiling op die verhoog

Kellermann, Antoinette 12 1900 (has links)
Thesis (MDram)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The appearance of actresses on stage during the seventeenth century gave rise to the discarding of gender boundaries and the exploration of male characters. By investigating the cause and effect and the critical value of actresses assuming breeches parts (“broekrolle”) within specific historical time lines and theatrical traditions, and a comparative study of the creation and portrayal of breeches parts within a South African context, I will endeavour to assess the success of the assumption of male characters on the stage. Actresses performing breeches parts were not necessarily in competition with their male counterparts, but were often influenced by their socio-economic situations, as well as their natural inclination to male identities. The appearance or beauty of the female performer has almost always been a defining factor in the casting of a part and it is therefore possible that some actresses chose to perform breeches parts because their natural attributes might not have fallen within the general concept of beauty. Although the assumption of male characters was often categorized as sensation seeking and selfglorification, it was accepted during certain historical periods and the theatrical traditions of the time. Breeches parts contributed towards the actress’s level of skills, and thus to their financial gain. Within a South African context a comparative and personal perception will be investigated in relation to the experiences of the above-mentioned actresses. Because of the hybrid quality of the character of Ella/Max Gericke in As die Broek Pas (Man to Man), in other words, the duality of her performed identity, the breeches part of Ella/Max differs from the traditional concept of breeches performances. This aspect contributes to the process of self-assessment through performance as research – situated knowledge. / AFRIKAANSE OPSOMMING: Die vroulike toneelspeler het reeds gedurende die laat sewentiende eeu oor geslagsgrense heen manskarakters (broekrolle) begin vertolk. Deur ondersoek in te stel na die oorsake, gevolge en kritiese waarde van aktrises se aanneming van broekrolle binne ’n spesifieke tydruimte en teaterkonvensies en ’n vergelykende proses wat hierdie skepping en uitbeelding van ’n broekrol in kontemporêre Suid-Afrika belig, kan gepoog word om te bepaal hoe suksesvol hierdie geslagsaanneming op die dramatiese ruimte van die verhoog was en is. Die emansipasie van die vrou en die ontbanning van vroulike toneelspelers het dit vir aktrises moontlik gemaak om buite hulle tradisionele geslagsraamwerk die toneelkarakters van die man te betree en te ontgin. Hierdie toetrede tot broekrolle (“breeches parts”) was nie noodwendig ’n poging om met die man op sy gebied te wedywer nie, maar kan toegeskryf word aan sosio-ekonomiese toestande, sowel as ’n natuurlike voorkeur vir ’n manlike identiteit. Die aktrise se voorkoms is en was nog altyd ’n bepalende faktor ten opsigte van die rolle waarin sy beset word. Dit is dus verstaanbaar dat sommige aktrises uit die aard van hulle ingesteldheid teenoor hul eie voorkoms die keuse maak om manskarakters te vertolk. Die gevolge van hierdie aanneming van manlike karakters is soms as sensasionele vertoon en selfverheerliking beskou, maar is steeds aanvaar binne die teaterkonvensies van sekere tydperke. Daarbenewens het dit die betrokke aktrises se aansien ten opsigte van hulle vaardighede op die verhoog en hul ekonomiese status positief beïnvloed. Die persoonlike gewaarwordinge wat ten opsigte van ’n vergelykende proses binne ’n Suid- Afrikaanse konteks gevolg is, sluit aan by die navorsing oor genoemde broekrolvertolkers. Daar is wel verskille, aangesien die geval van Ella/Max Gericke in As die Broek Pas, nie binne die tradisionele opset van die broekrol val nie, as gevolg van die dualiteit wat in die broekrol teenwoordig is, en dit as ’n hibriede karakter gesien kan word. Hierdie aspek leen hom tot kritiese selfevaluasie binne die gebruik van “performance” as navorsing – “situated knowledge”.
