Thesis. (D. Tech. - Business, Faculty of Management Sciences)--Vaal University of Technology, 2010. / The study explored the South African coal mining industry and it’s role players to establish the causes of the bottlenecks/constraints experienced in the coal mining industry supply chain. A qualitative research paradigm methodology was used. Both theoretical and philosophical assumptions were utilised with inferences from and references to works by other researchers to broaden the knowledge horizons for the study. Thirteen supply chain executives and professionals from the key role players in the coal mining industry were interviewed and provided invaluable input for the study. The study determined the presence of communication barriers between the industry role players in the public and private institutions that culminated in main themes and sub-themes being established from which the industry constraints were uncovered. The study identified six main constraints affecting the various role players within the coal mining supply chain and it culminated in the model that would enable the industry to minimise such constraints. To this end, the study proposes the development of an Integrated Strategy for the Development of Coal Mining (ISDCM).The model is based on the public and private partnership arrangement that would alleviate most of the prevailing constraints when implemented. The model would furthermore have the capacity to rectify most of the existing constraints. It would be funded from the commercial sector and would operate on triple bottom lines of economic, social and environmental factors, with equal weight. This is a desirable direction for the future in order to maintain sustainable development. Emanating from the study are policy and research recommendations for the South African coal mining industry, covering the coordination of the critical areas of the proposed integrated strategy for the development of the coal mining industry. Such recommendations include further research into new coal mines and power stations as well as perceptions and expectations of potential investors in the industry, among others.

Thesis (MPhil)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: In the last decade, the use of computers has proliferated the industrial arena in South Africa. Due to frequent changes in computer programs and developments in the computing field, users have often been adversely affected. Users experience problems with computer programs that are not user friendly. Usability is about satisfying the user needs by allowing the user to accomplish their goals quickly, efficiently and easily. Thus it is crucial that industries invest in computer programs that offer optimum usability. In this research an attempt is made to provide a framework for methodology that can be used to test and evaluate usability in the Transwerk Risk Management Information System, that is Computer Assisted Risk Management Systems (CARMS). I first consider the difference between unusable and usable programs. Usability properties are then identified including properties enhancing effectiveness, efficiency, flexibility, laemability and attitude of the computer program. The CARMS components or modules and users were identified. Usability problems were identified that cause the users to be selective and discouraged to use other components of CARMS. To further verified and address the usability problems identified, the whole program needs to be tested and evaluated. The methodology was laid for how to do usability testing and evaluation in computer program that are currently in use like CARMS. Benefits and limitations of testing and evaluating usability were detailed in this research. It is recommended that, testing and evaluating usability should be done to prevent errors, dissatisfaction and to improve usability of the CARMS program. / AFRIKAANSE OPSOMMING: In die laaste dekade het die gebruik van rekenaars uitgebrei in die industriele arena in Suid-Afrika. Weens gereelde veranderings in rekenaar programme en ontwikkellings in die informatika veld is gebruikers gereeld nadelig geraak. Gebruikers ervaar probleme met rekenaar programme wat nie gebruikersvriendelik is nie. Bruikbaarheid het te make met bevrediging van gebruikersbehoeftes deur hulle in staat te stel om hulle doelwitte vinnig, doelmatig en maklik te bereik. Dit is dus van kritiese belang dat industriee investeer in rekenaar programme wat optimale bruikbaarheid bied. In hierdie navorsing word gepoog om 'n raamwerk vir metodologie wat gebruik kan word om die bruikbaarheid van die "Transwerk Risk Management Information System" (dit is "Computer Assisted Risk Management Systems" of CARMS) te toets en te evalueer. Ek bespreek eerstens die verskil tussen onbruikbare en bruikbare programme. Bruikbaarheidseienskappe word dan geidentifiseer, insluitend eienskappe wat doeltreffendheid, doelmatigheid, buigsaamheid, aanleerbaarheid en houding van die rekenaar program verbeter. Die CARMS komponente of modules en gebruikers is geidentifiseer. Bruikbaarheidsprobleme is geidentifiseer wat veroorsaak dat gebruikers selektief raak en ontmoedig raak om ander komponente van CARMS te gebruik. Om verder die geidentifiseerde bruikbaarheidsprobleme te verifieer en adreseer moet die hele program getoets en evalueer word. Die metodologie is vasgele waarvolgens bruikbaarheidstoetsing en evaluasie van rekenaar programme wat tans in gebruik is (soos CARMS) gedoen kan word. Voordele en beperkings van bruikbaarheidstoetsing en -evaluasie is in hierdie navorsing vervat. Dit word aanbeveel dat bruikbaarheidstoetsing en -evaluasie gedoen moet word om foute en ontevredenheid te voorkom en om die bruikbaarheid van die CARMS program te verbeter.

Thesis (DPhil (Logistics))--University of Stellenbosch, 2007. / South Africa currently experiences the double jeopardy problem of catching up to global economic competitiveness whilst at the same time feeling the pressures of sustainability management spearheaded by a global agenda. Global sustainability is defined as growth that is shared without depleting natural resources or damaging the environment. Academic disciplines are challenged to make a contribution and economics as such should contribute by providing the lead and lag indicators for the planning and measurement of scarce resources usuage. This integrative view includes economic sub-disciplines, such as logistics. This integrative view is an acknowledged part of the economics discipline, except that the macro-economic context of some sub-disciplines, such as logistics, often receives less attention during the course of academic activities. The distribution of resources and outputs in the economy is a logistics controlled cross-cutting factor, but suffers from a lack of macro-economic perspective, and lead and lag orientated measurement. This state of the affairs is a historic backlog of logistics and its specific position within economics. During the primary economic era the world began to configure networks and markets, which became more pronounced and settled with the dawn and settling of the industrial era. Logistics then was a “given” and did not receive much thought even as industrial, market economies developed. Transport was regarded as an administered cost, i.e. inefficiencies in logistics systems were evenly distributed between competitors, not giving any specific entity an advantage. With the advent of global competition and the diminishing returns on other cost saving measures, companies began to collaborate and integrate logistics functions within value chains, but the administered part of transport costs failed to receive the attention it required. In this way, global competitors did begin to experience disadvantages on a national level as whole economies suffered from inefficiencies in logistics and specifically transport systems.

The purpose of this study was to explore the strategising practices of sustainability champions at Transnet, a South African state-owned enterprise (SOE). The study set out to discover what these micro-strategising practices were and what strategic outcomes they had for the organisation at the corporate level of strategy praxis. The problem that this research sought to address was the need for greater progress towards corporate sustainability and the lack of research into the role, contributions and practices of sustainability champions in formal sustainability roles within relatively large organisations. This exploration was carried out in the form of a qualitative single-case study which drew on serial interviews (two per participant) and case documentation as sources of evidence. The data were analysed using Applied Thematic Analysis (ATA) in the CAQDAS software Atlas.ti. The study answered the research questions and found that sustainability champions engaged in seven sets of strategising practices with seven corresponding strategic outcomes. While it was not the intention of the study to develop a conceptual model, the process of synthesising the main findings resulted in a model termed the web of sustainable strategising. The study concludes that sustainability champions are strategists who aid their organisation in the pursuit of corporate sustainability while influencing the direction of macro-institutional arrangements towards sustainable development. These results cannot be generalised, but they are transferrable to similar contexts. / Business Management / M. Com. (Business Management)

A severe capital shortage in South Africa during the 1980s resulted in significant losses for both freight and passenger rail, which gave rise to cutbacks in new investments for rail. By 1986 expenditure on fixed rail assets was reduced from R1.44 billion to R500 million; this was the beginning of the decline of freight rail. During this period freight transport was deregulated and road freight used this opportunity to compete with rail transport in the same market segment by transporting bulk goods on long hauls. The result of this was an increase in truck traffic on the roads, causing a negative impact on the conditions of the road and placing freight rail in a continuous decline, leading to the obsolete state of the rail infrastructure, rolling stock and its under-utilisation. This had a detrimental impact on freight rail and the economy. Having realised the extent of the problem, government, through the Department of Transport (DoT), decided to intervene by changing the current model of the freight transport system. To that effect the DoT is in the process of developing a National Rail Policy, with the main focus being to encourage the shift of freight transportation of bulk commodities from road to rail. As the National Rail Agency, Transnet undertakes all South Africa‟s freight rail operations through its Transnet Freight Rail (TFR) division. As such, TFR is ultimately responsible for the implementation of the road to rail implementation project. To that effect, TFR developed the MDS to revitalise itself and ensure its success. The objective of this research is to (a) assess the capacity of TFR to successfully implement the road to rail policy; (b) determine whether the implementation of road to rail will lead to freight rail efficiency and competitiveness, reliability and sustainability; and (c) establish the industry‟s reaction towards the shift from road to rail. In order to respond to the research question, qualitative research was chosen as the most appropriate approach. This facilitated an in-depth exploration and understanding of the issues around the road to rail project including how the industry feels about the issue, as well as an exploration of other possible alternatives which could provide the same or better results in a simpler and more effective manner. This research may serve as additional information for authorities to consider during the implementation of the road to rail project, and could render a better chance of success. Upon completion of this research the author concluded that Transnet Freight Rail has a good chance of success. The implementation of road to rail is being given adequate attention. Integration is possible as the industry welcomes and supports the road to rail programme, in fact a number of collaboration agreements already exist between rail and other transport modes. This will enable Transnet Freight Rail to achieve efficiency, sustainability and a competitive advantage within the seven year timeframe of the MDS. / Graduate School of Business Leadership (SBL) / M.

Based on literature review, statistics of waste management at ports in South Africa is hard to come by. The research critically assessed the current waste management practices at Transnet National Ports Authority. Transnet National Ports Authority, Port of Richards Bay (TNPA RCB) was used as a case study to examine the different types and quantities of waste produced, analysing the current waste management model as well as determining TNPA RCB compliance to pertinent waste legislation. A 10 day waste audit was conducted to obtain quantitative data and to identify the different types of waste generated. The baseline data resulting from the waste audit conducted for the first time since the establishment of the TNPA RCB, found 402 kg of general waste generated, 74 kg of this total is segregated for recycling and the remaining 328 kg is landfilled. The overall conclusion gained during compliance audit was that the TNPA RCB was partly compliant with pertinent waste legislation and obligations. Furthermore, questionnaires about waste were sent to staff members working in offices to get an overview of how they deal with current waste management. A number of barriers to sustainable waste management were identified, including: lack of knowledge and awareness; constraints on facilities and human resources; culture that resists change and contamination. To overcome these, there needs to be education, as well as co-operation between top management, staff and waste service providers to help implement new strategies. The primary conclusions from this dissertation are that there are opportunities to divert waste streams from landfill and to attain a sustainable waste management system at TNPA RCB. / Environmental Sciences / M.
