Demolish-IT : the development of a process management tool for the demolition industry

Qu, S. January 2010 (has links)
Today most demolition projects undertaken are complex and involve many parties who must comply with a myriad of regulations as well as other constraints (e.g. finance). The management of demolition projects requires individual team members to have a wide range of skills and knowledge in addition to practical experience. Demolition processes currently operated are frequently performed in an unstructured, intuitive manner with considerable reliance on experience, skill, knowledge or subjective judgement of the demolition engineer or other individual responsible for a demolition project. Research on demolition ‘process management' is a new area that has rarely been addressed. However, within the building design and construction management sectors, there are a number of intelligent solutions that have been developed to assist in the management of business processes and business process re-engineering. Process management systems and process mapping through the use of Information Communication and Technology (ICT) technology have been applied to help the construction industry significantly improve performance. In an attempt to provide intelligent support to the management of dynamic demolition processes, this research reports upon that was developed using ICT applications a management system prototype entitled “Demolish-IT”. The prototype of Demolish-IT utilises four tiers of information which includes: (1) the standard demolition process map; (2) user-defined demolition process map; (3) demolition task manager; and (4) database of demolition process requirements. The prototype provides on ICT platform that unifies demolition processes and requirements to achieve improved process management. The research involved a combination of face-to-face interviews with demolition experts; real projects document reviews and site observation to produce the generic demolition process map. Other products of the work included: database solutions to store demolition process requirements; and process modelling to manage demolition task compliance flow within relevant industry standards. Evaluation of the research work proved its validity, acceptance and applicability within industry. Future work will aim to transpose the outputs into commercially viable software.

Sustainability reporting process model using business intelligence

Alxneit, Thorsten Julius January 2015 (has links)
Sustainability including the reporting requirements is one of the most relevant topics for companies. In recent years, many software providers have launched new software tools targeting companies committed to implementing sustainability reporting. But it’s not only companies willing to use their Business Intelligence (BI) solution, there are also basic principles such as the single source of truth and tendencies to combine sustainability reporting with the financial reporting (Integrated Reporting) The IT integration of sustainability reporting has received limited attention by scientific research and can be facilitated using BI systems. This has to be done both to anticipate the economic demand for integrated reporting from an IT perspective as well as for ensuring the reporting of revisable data. Through the adaption of BI systems, necessary environmental and social changes can be addressed rather than merely displaying sustainability data from additional, detached systems or generic spreadsheet applications. This thesis presents research in the two domains sustainability reporting and Business Intelligence and provides a method to support companies willing to implement sustainability reporting with BI. SureBI presented within this thesis is developed to address experts from both sustainability and BI. At first BI is researched from a IT and project perspective and a novel BI reporting process is developed. Then, sustainability reporting is researched focusing on the reporting content and a sustainability reporting process is derived. Based on these two reporting processes SureBI is developed, a step-by-step process method, aiming to guide companies through the process of implementing sustainability reporting using their BI environment. Concluding, an evaluation and implementation assesses the suitability and correctness of the process model and exemplarily implements crucial IT tasks of the process. The novel combination of these two topics indicates challenges from both fields. In case of BI, users face problems regarding historically grown systems and lacking implementation strategies. In case of sustainability, the mostly voluntary manner of this reporting leads to an uncertainty as to which indicators have to be reported. The resulting SureBI addresses and highlights these challenges and provides methods for the addressing and prioritization of new stakeholders, the prioritization of the reporting content and describes possibilities to integrate the high amount of estimation figures using BI. Results prove that sustainability reporting could and should be implemented using existing BI solutions.

Value creation within societal entrepreneurship : a process perspective

Åslund, Anna January 2013 (has links)
Social entrepreneurship is given considerable attention within literature and academic research despite that fact it is an area that needs considerable attention and research. The main purpose for societal entrepreneurs is to create societal value but there can be difficulties to understand value creation within the area. Important components within Total Quality Management (TQM) are process orientation and value creation. A TQM perspective with processes in focus provides opportunities to clarify societal value creation within societal entrepreneurship initiatives. The main purpose of this thesis has been to explore how societal value is created within the area of societal entrepreneurship and the underlying purpose has been to contribute to the development of knowledge and understanding about the societal entrepreneurship area. In order to fulfil the purpose one literature case study and three empirical case studies have been conducted with processes in focus. The literature case study was conducted first and it resulted in a theoretical process map based on a process perspective, which showed how societal value was created within a societal entrepreneurship initiative. After that the three empirical case studies were conducted separately and the findings from the empirical case studies were compared with the previously developed theoretical process map. A cross case analysis was made to find out if the process map could be confirmed, developed or rejected. The result of the case studies contributes to earlier findings within research and gives a common, comprehensive and simplified picture of a complex phenomenon and an opportunity to understand how societal value is created. A general overall process map is presented that gives a picture of how value is created within the area of societal entrepreneurship. The result shows the management process and support process fields. The map also shows a main process that is further developed with input, output and sub processes. The studies point out that societal value is created through processes and that societal value creation can be described out of a process orientation perspective. Important components to create societal value have been found to be: 'unidentified needs'; 'knowledge about the context'; 'identified need'; 'an idea or a vision'; and some kind of 'organization' and important activities to create value seem to be: 'being in the context'; 'analysis of knowledge'; 'searching for solution'; 'organize and mobilize'; and 'realize'. Fields where support processes are performed that are of importance in societal value creation have been identified. Those fields are 'creation of financing opportunities'; 'performance of political decisions and acts'; 'development and use of networks'; 'establishment of initiative'; 'creation of media information'; 'development and use of scientific results'; and 'development and use of competence'. The map does have potential for development. Further studies need to be done within the area concerning how societal value is created and to get an even more comprehensive process map of the societal entrepreneurship area but the result presented in this thesis is a start to understanding how societal value is created and to develop knowledge and understanding of the societal entrepreneurship area.

Developing an integrated method of controlling the flow of departing passengers : a study of passenger departure processes at Abu Dhabi International Airport

Al-Dhaheri, Abdulla January 2015 (has links)
Today, airports form a key part of global infrastructure in an increasingly globalised world. There is great competition between them to attract passengers and serve airlines in their role of transporting people regionally and internationally. Abu Dhabi International Airport is one such airport. Terminal 3 is the home of Abu Dhabi’s major carrier, Etihad Airways, one of the world’s fastest-growing international airlines. The research described in this thesis focuses on applying the Lean methodology to the passenger departure process in Terminal 3. The essential essence of ‘Lean’ is doing more with fewer resources by adopting a programme of continuous process improvement resulting in continually declining costs, mistakes and work-in-progress. The special environment of any airport, especially a major international hub made applying Lean principles difficult. This resulted from the large presence of Class I wastes or muda which could potentially change, perhaps dramatically, at short notice. This made this research significantly different from previous applications of Lean philosophy. Also, large, cumulative variations in demand set in an environment where rapid expansion of the airport is taking place also created major difficulties because of the shifting flow of passengers. Despite this, the research succeeded in achieving its aim and developed various rules from parameters based on the acronym SERVICE and an associated implementation methodology based on the Lean philosophy. Together these will help airline managers and staff to eliminate the waste of available resources and so increase passenger flow through various stages of the process in line with Lean philosophy. The research makes several important contributions to knowledge, especially in the field of Lean improvements. The contribution of this work arises from its systematic examination of the passenger departure process. The research has facilitated developing a detailed model which addresses both particular process groups and the effects of passenger class on the allocation and use of resources. This research has shown that large differences exist between the operating environment of a major international airport and those processes to which Lean principles have previously been applied. Nevertheless, despite these differences, this research has proved the Lean philosophy may be usefully applied to airport operations. Operating conditions within the passenger departure process mean that understanding the special operating environment of airports is vital. This research resulted in a discrete event simulation model of the airport much more accurate and detailed than those described in previous studies of passenger departure processes. The research then proved an improved model, which may be used experimentally to support conclusions reached from the broader application of Lean philosophy. The research observed and analysed the effects of large and cumulative peaks and troughs in demand against a background of rapid development of Abu Dhabi Airport. The researcher also evaluated the special internal and external effects on the processes, often at short notice. Consequently, there is no single ‘universal’ solution because of the major need for operational flexibility and for a close correlation between operational and strategic need. Despite these many difficulties the results of this research are a practical and straightforward series of improvements, which may be applied by airport staff themselves without need for complex computer models, simulation or dedicated experts. This will create conditions for continuously improving process performance during the passenger departure process. It will also help managers accurately identify critical areas where more radical action of increasing physical resources is needed. Finally, based on findings, the research makes several recommendations for further work.

Renewable liquid transport fuels from microbes and waste resources

Jenkins, Rhodri January 2015 (has links)
In order to satisfy the global requirement for transport fuel sustainably, renewable liquid biofuels must be developed. Currently, two biofuels dominate the market; bioethanol for spark ignition and biodiesel for compression ignition engines. However, both fuels exhibit technical issues such as low energy density, poor low temperature performance and poor stability. In addition, bioethanol and biodiesel sourced from first generation feedstocks use arable land in competition with food production, and can only meet a fraction of the current demand. To address these issues it is vital that biofuels be developed from truly sustainable sources, such as lignocellulosic waste resources, and possess improved physical properties. To improve and control the physical properties of a fuel for specific application, one must be able to tailor the products formed in its production process. All studies within this thesis, therefore, have the aim of assessing the fuels produced for their variability in physical property, or the aim of directing the process considered to specific fuel molecules. In Chapter 2, spent coffee grounds from a range of geographical locations, bean types and brewing processes were assessed as a potential feedstock for biodiesel production. While the lipid yield was comparable to that of conventional biodiesel sources, the fatty acid profile remained constant irrespective of the coffee source. Despite this lack of variation, the fuel properties varied widely, presumably due to a range of alternative biomolecules present in the lipid. Though coffee biodiesel was produced from a waste product, the fuel properties were found to be akin to palm oil biodiesel, with a high viscosity and pour point. The blend level would therefore be restricted. In Chapter 3 the coffee lipid, as well as a range of microbial oils potentially derived from renewable sources were transformed into a novel aviation and road transport fuel through cross-metathesis with ethene. Hoveyda-Grubbs 2nd generation catalyst was found to be the most suitable, achieving 41% terminal bond selectivity under optimum conditions. Metathesis yielded three fractions: an alkene hydrocarbon fraction suitable for aviation, a shorter chain triglyceride fraction that upon transesterification produced a short chain biodiesel fuel, and a multifunctional volatile alkene fraction that could potentially have application in the polymer industry. Though there was variation for the road transport fuel fraction due to the presence of long chain saturates, the compounds fell within the US standard for biodiesel. The aviation fraction lowered the viscosity, increased the energy density, and remained soluble with Jet A-1 down to the required freezing point. Oleaginous organisms generally only produce a maximum of 40% lipid, leaving a large portion of fermentable biomass. In Chapter 4, a variety of ethyl and butyl esters of organic acids – potentially obtainable from fermentation – were assessed for their suitability as fuels in comparison to bioethanol. One product, butyl butyrate, was deemed suitable as a Jet A-1 replacement while four products, diethyl succinate, dibutyl succinate, dibutyl fumarate and dibutyl malonate, were considered as potential blending agents for diesel. Diethyl succinate, being the most economically viable of the four, was chosen for an on-engine test using a 20 vol% blend of DES (DES 20) on a chassis dynamometer under pseudo-steady state conditions. DES20 was found to cause an increase in fuel demand and NOx emissions, and a decrease in exhaust temperature, wheel force, and CO emissions. While fermentation is generally directed to one product, producing unimolecular fuels, they do not convert the entirety of the biomass available. An alternative chemical transformation is pyrolysis. In Chapter 5, zeolite-catalysed fast pyrolysis of a model compound representative of the ketonic portion of biomass pyrolysis vapour – mesityl oxide – was carried out. The aim of this study was to understand the mechanistic changes that occur, which could lead to improved bio-oil yields and more directed fuel properties of the pyrolysis oil. While HZSM-5 and Cu ZSM-5 showed no activity for hydrogenation and little activity for oligomerisation, Pd ZSM-5 led to near-complete selective hydrogenation of mesityl oxide to methyl isobutyl ketone, though this reduced at higher temperatures. At lower temperature (150-250 °C), a small amount of useful oligomerisation was observed, which could potentially lead to a selective pyrolysis oligomerisation reaction pathway.

The application of multivariate statistical analysis and batch process control in industrial processes

Lin, Haisheng January 2010 (has links)
To manufacture safe, effective and affordable medicines with greater efficiency, process analytical technology (PAT) has been introduced by the Food and Drug Agency to encourage the pharmaceutical industry to develop and design well-understood processes. PAT requires chemical imaging techniques to be used to collect process variables for real-time process analysis. Multivariate statistical analysis tools and process control tools are important for implementing PAT in the development and manufacture of pharmaceuticals as they enable information to be extracted from the PAT measurements. Multivariate statistical analysis methods such as principal component analysis (PCA) and independent component analysis (ICA) are applied in this thesis to extract information regarding a pharmaceutical tablet. ICA was found to outperform PCA and was able to identify the presence of five different materials and their spatial distribution around the tablet.Another important area for PAT is in improving the control of processes. In the pharmaceutical industry, many of the processes operate in a batch strategy, which introduces difficult control challenges. Near-infrared (NIR) spectroscopy is a non-destructive analytical technique that has been used extensively to extract chemical and physical information from a product sample based on the scattering effect of light. In this thesis, NIR measurements were incorporated as feedback information into several control strategies. Although these controllers performed reasonably well, they could only regulate the NIR spectrum at a number of wavenumbers, rather than over the full spectrum.In an attempt to regulate the entire NIR spectrum, a novel control algorithm was developed. This controller was found to be superior to the only comparable controller and able to regulate the NIR similarly. The benefits of the proposed controller were demonstrated using a benchmark simulation of a batch reactor.
