  • Description: M.Ing. , Until very recently reactive maintenance was still used in the mining industry. Equipment failures occurred without warning and resulted in catastrophic breakdowns and large production losses and maintenance cost. As a result, the mining industry turned to preventative maintenance that focused on changing parts before they fail. Although preventative maintenance was an improvement over reactive maintenance practices, equipment reliability did not necessarily improve. Next came predictive diagnostics, which monitored the health of components within assemblies, and thereby predicting the life expectancy of assemblies through vibration analysis, infrared thermography, lubrication and oil analysis and ultrasonic detection. However, the level of success could not be achieved. Many hours and a lot of money are spent in developing and implementing a maintenance management system, but without the correct approach, efficient maintenance might not be achieved. The overall objective of this dissertation is to introduce a logical approach to managing the maintenance of mining equipment over the economical life of the equipment. This concept can be defined as Life Cycle Management. The research included in this dissertation is partially aimed at developing the Life Cycle Management program for P&H MinePro Services A division of Joy Global (South Africa) (Pty) Ltd. The dissertation also includes case studies on the P&H Mining Equipment (Blast Hole Drills) and their alliance partners (LeTourneau Front-end Loaders). The dissertation focuses on the cradle to grave approach of maintenance for mining machinery, referred to as the Life Cycle Management of Mining Machinery.

  • Description: M.Ing. , This dissertation investigates the fatigue and monotonic tensile properties of cast aluminium alloy wheels in various post cast conditions. It was found that monotonic tensile properties could be used in the original universal slopes method of Manson to predict the fatigue properties as a conservative first approximation for A356 cast aluminium alloy wheels. Using finite element analysis and the predicted fatigue properties the fatigue life of A356 aluminium alloy wheels could be determined. Further work is required on the surface effect of paint on the wheel and residual stress on the surface of the wheel.

  • Description: M.Ing. , The focus of this dissertation is on the evaluation of management in traffic safety, and how it is applied, using the Road Traffic Management Corporation (RTMC) as a case study. Road Traffic Management in South Africa is in a state of crisis. The constitution provides for concurrency with respect to road traffic management, however, no mechanism has been implemented for co-operation and coordination. It has been found that the current institutional arrangements are not conducive to co-ordination and rapid interventions. Due to the scarcity of resources and the desire to streamline the institutional arrangements, an innovative model has been developed which will perform road traffic management collectively, the Road Traffic Management Corporation, RTMC. The implementation of the RTMC will require full co-operation and acceptance by all the various departments concerned, from National Government level, through to Provincial levels, and the Local Authorities. Before the Corporation can be implemented, the funding needs to be secured, and the source of the funding must be stable and committed. The implementing of such a corporation will be delicate, and organizational structure needs to be clear to all parties. At this early stage of the RTMC, the methods of management already used by the RTMC need to be compared to proper management principles, to ensure that the RTMC will have the best structure to ensure its success. Any uncertainties or concerns that may exist among those involved at lower levels can be communicated to top-level management implementing the corporation. By conducting an independent, external investigation, any short falls can be identified which may have been over looked previously. This dissertation aims to ensure that the RTMC adheres to the relevant management principles, focussing on the objective of improving road safety. A questionnaire is devised for the National Department of Transport, so that an independent view of the vision of the RTMC can be acquired. The organizational structure proposed by the RTMC is examined and evaluated to determine the relationship, communication channels, functions and responsibilities, which are intended between the various levels of management and stakeholders. The funding of a corporation such as the RTMC is considered, as the source of such funds needs to be secured before the RTMC can be implemented. A preliminary budget prepared for the RTMC is compared to what funding has been made available. The main objective of the RTMC is to improve road safety. Therefore, the process it intends to use is evaluated to determine whether the goals it intends to achieve through this process are realistic. The engineering function required to improve road safety will also be evaluated in terms of what can be done by engineers to improve the safety on South African roads.

  • Description: M.Phil. , The important role that research and development (R&D) plays in the economic well being of a nation, and by implication the profitability of a business enterprise, has long been recognized. In this era, in which the world live in turbulent times, technology advances at an ever-increasing pace and customers needs are constantly changing. Global competition has reached unprecedented levels. Globalisation brings new economic powers and opportunities constantly. The global marketplace has emerged as a battlefield of the world, were many competitors are fighting for a share. These factors urge the need more than ever for new products, processes and services to be able to enter this battlefield and emerge as a victorious. The way to these new products, processes and services is the adaptation of an effective program of R&D. It is therefore important to appreciate the many aspects of the R&D function, which is the subject of this work. This research stresses the benefits that R&D brings to the nation and what measures that nation can adopt to promote R&D programs. The work also stresses the importance of R&D to private firms, and how the performance of such firms is linked to their use of technology and to the intensity of their R&D programs. Firms sustain economic growth and secure a competitive position by creating new products and new services, and these are the natural results of the R&D process. In the course of executing their R&D programs, firms are faced with many barriers and constraints that impede successful R&D activities. Many barriers have been identified and classified into different categories. Firms function in different environments, have different sizes, and different affiliations, hence it is difficult to suggest that there is a fixed set of R&D management practices that will fit all kinds of firms. In this research many general R&D management practices are recommended, which if implemented may lead to a successful R&D results. R&D is one of the important functions of the business; hence its strategy should be a natural extension of the business and should support this strategy. The concept of business strategy and why firms need to develop business strategy are discussed. Also elements needed to develop a best R&D strategy are recommended.

Towards improved project and product management in a software environment

  • Authors: Malan, Andre

  • Description: M.Ing. , The competitive world of commercial software development exacts unremitting regeneration, innovation and adjustment from each and every company that chooses to perform this function. The said regeneration, innovation and adjustment could result either from the proactive decisions of a company, or from its reaction to certain changes, such as changes in the market place and changes in available technologies. Should the business model fundamental to the software development of a company, however, fail to be adjusted for technological innovation (for example, object-orientated development), the chances of such innovations culminating in actual improvements in productivity are, however, greatly diminished. The principal aim of the present research study is to investigate the project-management and product-development processes within a specific organization selected as a case study, and, if possible, to propose improvements to these processes. Rubico, the selected company, has decided on account of observed marketing opportunities to focus on the development of software components and patterns for the financial-services sector. In order to realise the said focus, some of the current and envisaged activities of the company, for example, marketing and project delivery, have been outsourced to third parties. The Rubico Products Company (hereafter called Products) and Rubico Delivery Services (hereafter called Delivery Services) utilise a formalised methodology of interaction in order to find software solutions for their clients. Products is responsible for developing software components and software solutions, whilst Delivery Services specifies the said components and solutions with the client, in addition to reselling them to other clients. Products has entrusted the management of software products and patterns to product architects, whilst Delivery Services have employed project managers to manage the delivery of the said products and patterns. The golden thread that ties together the activities and roles of these two divisions is the product-delivery methodology to which both divisions subscribe. Proposals for the improvement of project management and product architecture are made not only in terms of a new definition for and in terms of the execution of the said processes, but also in terms of the responsibilities implied by these two roles. The present dissertation, however, contains merely the author’s opinions and conclusions in this connection, and does not necessarily reflect the vision and opinions of Rubico Company.

  • Description: M.Ing. , This dissertation deals with the structural integrity analysis of a low pressure (LP) turbine with transverse cracking. Cracks are initiated in the centre ring keyway of the shaft by a fretting mechanism and propagate during barring operation. The cracks arrest during normal operation when they are still relatively shallow. The aim of the calculations is to predict the transition where cracks start propagating by high cycle fatigue during normal operation of the shaft. Most influencing factors, including continuum mechanics, mathematical modelling, material behaviour, service loads and industry experience, are studied in detail as a precursor to the case study. The calculated results show that the case study is an example where the application of fracture mechanics on the crack-free stress field leads to erroneous results. There is a significant redistribution of stress in the presence of the crack so that the actual stress ratio, as calculated from three dimensional cracked models, varies significantly compared to the crack-free model. Calculated results, together with carefully researched material properties, confirm the postulated crack growth during barring operation and predict limiting crack sizes where high cycle fatigue would ensue during normal operation. The case study concludes that the shaft has a significant remaining life and that it can be returned to service with periodic non-destructive examinations.

Aspects of engineering project failure: a managerial approach

  • Date: 2009-02-26T12:22:11Z
  • Subjects: Project management , Building failures
  • Type: Thesis
  • Identifier: uj:8176 , http://hdl.handle.net/10210/2180
  • Description: M.Ing. , It is of cardinal importance to accept that failure is a fundamental part of every day life. The difference is however, that one does not only need to learn from ones own failures, but also from others’ failures. This is similar to the situation of not working harder, but working smarter. There are several factors within the project environment that can cause a project to fail, but once these factors have been identified the project manager can implement “preventive maintenance” to ensure that these factors do not affect the project. Further investigations on a recently failed project and questionnaires set-up by the author confirm the factors contributing to project failure as discussed in the literature case study. One way to manage these factors is by means of proper project management and risk management, which is a sub-set of project management. This dissertation highlights certain problem areas that can hinder project success and provides recommendations to achieve project success.

  • Description: M.Ing. , The purpose of this research investigation is to develop and simulate a current manufacturing production line, for a company by the name of Aerosud, using a 3- dimensional software tool called Delmia Quest ®. The company in question is a mechanical and aeronautical manufacturing organisation that supplies components to both the civil and military sectors to a variety of global points. The aim of this investigation was to develop a simulation model that, initially, mapped the actual workings of the real production line with the use of actual time data recorded through measurement. Secondly, various observations were made to discover how much work-in-progress (WIP) remains idle during the manufacturing procedure and how much productivity is reached after a standard production week of forty-five hours. Hence, the aim of the simulation model is to improve those two factors by increasing the productivity of the entire production line and reduce the amount of WIP idle to a minimum. To achieve this, the author created a baseline model for both the throughput time and the WIP at each cell of production. The results of these curves were obtained using actual statistical time data obtained during the observation period. These results were then plotted onto individual axis to visually identify the outputs. Next, the author analysed the baseline model, within the 3D virtual world of the software, to witness where possible errors exist in terms of throughput time and the amount of WIP idle at various stations of production. It was clearly identified that the cell with the most production problems, was assembly. The author thus identified possible methods of reducing these problems and simulated those actions. The results showed various improvements in the amount of throughput time gained as well as a significant reduction to the amount of WIP idle at that particular cell. The simulations were thus mapped onto the same axis as the baseline model, in terms of throughput time and WIP respectively. This provides visual identification to the outcome of such simulations so that the reader can identify clarity in the results. A basic comparison of each simulation was described with reference to the baseline curve in order to clarify what the results had shown. Finally, the investigation was concluded highlighting that the baseline model created was a good start to analysing the company’s production line; however, as further research, it was recommended that various types of improvements can still be made to this model in order to improve its realism when compared to the real production line.

  • Description: M.Phil. , In this study, diversity management is introduced as an issue of global concern. Based on the assumption that diversity, if well-managed, can be beneficial to organizations, a positive approach to diversity is strongly supported. Diversity management has an important role to play in South Africa for mainly two reasons. Firstly, because of South Africa's rich cultural history and apartheid legacy, diversity management issues arise as a concern more often than in other countries. Secondly, due to apartheid, South Africa was internationally isolated for many years, which gives issues around global competitiveness even more significance. In the South African context, the engineering sector is regarded as a motor for the country's development, in which the management of diverse workforces is highly relevant. This has to be seen in light of a serious challenge facing the sector, where diversity management requirements have to be reconciled with a skills shortage that seems to afflict the engineering sector in particular. All of these issues are illustrated by a case study. The practice of diversity management in Siemens South Africa serves to demonstrate that diversity management in South Africa is clearly centred on the contexts of race and race relations. Furthermore, the case study presents a comprehensive example of how a diverse workforce can be managed in a South African engineering company.

  • Description: M.Ing. , The telecommunications industry worldwide is experiencing massive downsizing activities as the mobile telecommunications market is flooded with mobile operators. In Europe and other leading countries world wide, fixed line operators are able to cover more than 90% of the population of the country and there is not such a necessity for a mobile service as in a country such as South Africa, where less than 50% of the population is connected to a fixed line operator. Together with many investors, planning to create substantial returns on investments saturated the communication market in these worldleading countries. When mobile data transfer, in the form of GPRS (General Packet Radios Services) and UMTS (Universal Mobile Telecommunication System), was developed it was estimated that the amount of mobile data transferred (via mobile operators) per annum would exceed the amount of data transferred by normal fixed line transport (fixed line operators). Many mobile cellular operators worldwide have invested in these technologies but their ROI (Return on Investment) is not nearly as good as was estimated in the initial feasibility study of the technologies. Together, these issues have had a negative impact on all the world leading mobile communication infrastructure suppliers, which had to downsize to accommodate the decrease in world business. Only 3rd world countries (such as in Africa) are still expanding their mobile networks and are creating some business opportunities for the world leading suppliers, but it is unfortunately not sufficient to sustain the current business. With the initial roll out of GSM (Global system for mobile communication) network infrastructure suppliers could ask what they want for the equipment and services supplied, as these were hard to imitate, but as the market grew, more competitors were able to meet their standards in equipment quality and better the price and service.

A case study in industrial risk management

  • Authors: Raubenheimer, Pieter Jacobus
  • Date: 2011-12-06
  • Subjects: Risk management
  • Type: Thesis
  • Identifier: uj:1853 , http://hdl.handle.net/10210/4210
  • Description: M.Ing. , This dissertation focuses on an industrial risk management case study, which aims to illustrate how the risks involved in a new project have to be identified, approached and managed. The aim of this dissertation is therefore to act as an example of modem risk management theory and implementation in an industrial engineering environment. The first part of the dissertation focuses on the theoretical background of risk management. It starts by giving the history of risk after which a definition of risk is concluded from a variety of text books. The history of risk shows how risk developed through the ages and evolved into a way of making sure that the right strategic decisions are taken. The following chapters focus on the frameworks that have been developed by different international parties to structure the risk management process. The financial environment is also highlighted as an industry in which risk has been developed to help companies tremendously in making investment decisions. Although there are fundamental differences between risk management in the industrial and financial environment, there are however a few similarities. One aspect that can be taken from the financial environment and be implemented in the industrial environment is the fact that risk management has to be done according to a fixed structure or framework. A short literature case study shows how businesses made crucial mistakes in the past, and how implementing modem risk management techniques can rectify these mistakes. A big part of risk management is not only the qualitative analysis, but also in the quantitative analysis, which was ignored in the literature case study. The theory behind these quantitative techniques is highlighted as the last theoretical background before the second part of the dissertation focuses on the risk involved in the expansion project of an oil refinery. After the theoretical background of the expansion project is given as an introduction to the case study, the quantitative analysis for the expansion project is done. Through A Case Study in Industrial Risk Management 2 the quantitative analysis, the high risks involved in the project are highlighted more clearly and numbers or figures will indicate how realistic the objectives of the project are. By monitoring and controlling these critical project variables through the project life cycle, the chances of achieving the project results are greatly increased.

  • Description: M.Ing. , As the title of the dissertation implies, 'control' and 'risk' are the core issues regarding the dissertation. The approach by which a property development company manages these two issues are the focal points. The primary research objective was to draw conclusions from feedback obtained via a property developer and compare the findings to its literature counterpart. Expanding on the primary objective one aimed to determine commonalties and differences (case study and literature) and derive logical explanations for those differences. The second research objective was a by-product from the first. That being if the property developer is controlling his risk in the best manner possible given the inherent restrictions, in other words is the system efficient. It was evident that control measures and ways to identify and manage risk were put in place by the developer. Most of the literature theory corresponds with that of the property developer. Elements of risk were noted via analysis of the results. One way of increasing the efficiency of the system would be to increase the focus/resources in the evaluation/planning phase. In turn by improving the control mechanisms it may be possible to improve the systems efficiency. Risk can not be eliminated in its entirety - it is part and parcel of any business, particularly that of property development. Risk and control are therefore critical elements in any business. Understanding the core issues surrounding those elements can only prove beneficial to a company's success. Furthermore, the dissertation raised important issues that may be addressed in future research. Issues that may be followed up on in future research include and are not limited to the following: • Analysis of control and risk management' methods on a broader scale, in terms of a larger survey population. • Investigate and analyze the efficiency of a property development company/companies. • Expand on various risk issues: - return on investment, the market, project site, the project, the process, the organization and contingency. • Expand on various control measures: - tools (charts, schedules etc.), communication.

  • Description: M.Phil. , This study identifies and evaluates dynamic models used to characterise the dynamic stiffness and phase angle of hydraulic elastomeric mounts that are primarily used as engine and operator cab isolators in vehicular applications. Linear models developed for hydraulic elastomeric mounts are analysed for their suitability to be used to characterise the dynamic stiffness and its phase angle in the low and high frequency range. A sensitivity analysis provides insight into the parameters with a high level of sensitivity to changes in model parameters. The models selected from the linear analysis are enhanced and updated by performing a quasi-linear analysis to compensate for the dynamic behaviour of certain parameters. Non-linear dynamic behaviour of the decoupler is also investigated. These models are then verified experimentally. To set-up an analytical model that can be used to predict the dynamic characteristics of the hydraulic elastomeric mount it is necessary to develop a physical model from which the system differential equations are extracted. From the physical model flow continuity equations and fluid momentum equations are developed to obtain an expression that describe the fluid response in the inertia track and decoupler respectively. Lumped parameter mechanical models are developed next from which equivalent differential equations are derived to describe the internal dynamics of the hydraulic mount. These differential equations along with the transmitted force equation directly derived from the physical model are used to develop the dynamic stiffness transfer function. Time domain input displacement and output transmitted force data are taken at a specific frequency and amplitude, and are used to generate hysteresis loops to extract the dynamic stiffness and phase angles. For most of the computational effort, both analytical and experimental, MATLAB programs are written to perform curve fitting, FFT calculation, numerical integration and dynamical simulation. Emphasis is placed on the dynamic considerations of hydraulic mount design in the automotive industry and where machines are subjected to shock and vibration. The results and techniques used to model and the mounts are useful to designers in the field of shock and vibration isolation. Finally, the aim of the work is to keep the dynamic models as simple as possible, to be used effectively in the identification of the structural dynamic characteristics of hydraulic elastomeric mounts. To avoid complexity two models are used to describe the dynamics of the mount, one model for the low frequency, large amplitude conditions and one for the high frequency, small amplitude conditions. The information is then used to determine how the mount will respond under certain dynamical conditions.

  • Description: M.Phil. , Procurement, design and construction of an engineering or building project is a process that involves the broadest range of engineering and construction skills. There are risks throughout that can lead to a strategy that cannot succeed in terms of time, cost effectiveness, quality and profitability. There are also various contracting approaches employed in both building and engineering construction projects. Each has its own advantages, disadvantages, degree of flexibility, incentives and allocation of risks. A risk profile leads to important aspects considered in selecting a suitable contracting strategy for a construction project. The risk considered includes among others the design and functionality, variations, errors and/or omissions, budget overruns, price fluctuations, project timing, change in quantities, design and construction defects, etc (Morton and Jagger, 1995). In South Africa's tradition, the responsibilities of design and construction of projects have been separated, where the contractors undertake to provide the works in accordance with employer's and/or employer's agent's design and specifications. Disadvantages of this strategy include among others the fact that the design and specifications may not suit the construction process in terms of time cost savings. More than often this approach results in an adversarial relationship between the professional team and the contractor, and between professional team members. Globally, especially in developed countries, projects were executed using design and build strategy (Construction world, April 2006). This is an arrangement whereby the contractor assumes the responsibility of producing the design and the works. Recently the construction industry has been experiencing an unprecedented high level of economic growth both locally and in the global arena. In an attempt by construction stakeholders to redefine the approach to contracting to facilitate delivery, partnering evolved to bring all parties together to form common goals, to integrate design and construction into a collaborative working by involving contractors at an earlier stage, to set up mechanisms to resolve disputes and to share the risk and rewards of projects (Gould and Joyce, 2003).
