Human, Ricardo Ronald. "Retention strategies of technical graded employees at Transnet." Thesis, Nelson Mandela Metropolitan University, 2014. http://hdl.handle.net/10948/11080.
Full textAbstract:
The recruitment and retention of personnel plays an important role in assisting organisations to adapt and remain competitive, thus ensuring their financial sustainability and becoming a leader in the market. It is also a crucial element in assisting organisations in reaching their long and short term goals. The employment and retention of highly skilled employees is a costly exercise and staff turnover impacts negatively, not only on a financial level but also on the organisation as a whole. The immediate implementation of specific strategies that ensures the recruitment and retention of these employees will guarantee a reduction in employee turnover thus ensuring organisational competitiveness. The purpose of this study was to investigate the organisational factors impacting on employee retention at Transnet Freight Rail (TFR). The population group for the study included 34 TFR employees from the G graded salary scale. The response rate for the questionnaire was 100% with the Likert scale instrument consisting of 27 questions divided into two sections: Section one explored the demographic profile of the respondents; Section two focused on getting responses on the five organisational factors impacting on employee retention namely: organisational association; monetary compensation; work satisfaction; work enrichment; career development. The following research design was adopted: Step 1: A literature review was conducted to determine the various organisational factors impacting on employee retention. Step 2: From the literature review the researcher structured the research questionnaire. Step 3: The results of the survey were analysed and interpreted. Step 4: Conclusions and recommendations were done.

Full textAbstract:
The study is about evaluating supervisor performance at Transnet Port Terminals (TPT) and the impact it has in the business world in general. The aim of the study was to evaluate the quality of supervisors at Transnet Port Terminals (TPT) in the Eastern Cape. The sample size of 43 supervisors working at TPT from different departments like operations, planning, key accounts and procurement participated in the study. The sampled supervisors are between the ages of 20 and 59 years and was composed of females and predominantly males. The data was gathered through a questionnaire that was designed particularly to address the lack of quality of supervisory support at TPT. The response from respondents were tied to themes that were constructed, which are: (a) organisational goals; vision and management competencies; (b) communication; (c) performance cycle-setting of goals; (d) supervisor/supervisee performance conversation; and (e) supervisory development programme. The literature gathered and deliberated on in the literature review emanate from different authors in the form of books, journals and treatises. The empirical results were linked to theories gathered from different authors. Research findings were used to curb the issues identified, which will be beneficial to both TPT and its employees. The recommendations were submitted to the company to look at developing an in-house supervisory programme, capacity building internally and creating platforms for effective communication.

Full textAbstract:
Thesis (MTech (Public Relations Management))--Cape Peninsula University of Technology, 2007.<br>In the twenty first century, companies are forced to transform and adapt continually to ensure their
survival and to stay competitive in a demanding and challenging business environment. Yet, 70 per cent of
all change initiatives fail and 28 per cent of the variance of change successes is directly linked to
employees. Research shows that one quarter to one third of the reasons why change fails or succeeds, is
directly linked to employee communication. Change implementation failures come at a high cost to
organisations. Research shows that poorly communicated strategies are the reason for approximately 14
per cent of lost financial value and that poor communication is the second largest factor that contributes to
the failure in implementing strategic change. This mini-dissertation aims to investigate change communication has and impact on the relationship
between employees and the organisation. The communication approach of Transnet during the
implementation of its Four Point Turnaround Strategy was investigated. Employees indicate that
organisational change cannot be introduced without regular up-ta-date communication to employees.
Once the Executive Management of Transnet actively communicating started with Transnet employees,
employees became more positive and supportive of the changes. However, concluding the sale and
belatedly informing the employees of Transnet Housing thereof increased employee resistance, negativity
and non-commitment.
The contribution this mini-dissertation will make to the public relations field lies therein that through
proper change communication, change can be implemented successfully within an organisation.
Inadequate change communication however negatively impacts on the employee/organisational
relationship and this in turn affects change implementation negatively. Change implementation failure
ultimately added costs to the company in terms of time and money. This understanding could assist
organisations to save millions, and in cases like Transnet, it could minimise huge losses and negative
impacts on the economy during organisational change implementation.

Full textAbstract:
The research is based on a case study of an internal newsletter, Platform. The objective was to obtain more information about Transnet Freight Rail employees‘ thoughts on its effectiveness and the effectiveness of internal newsletters by using Platform as an example. The treatise explored the perceptions of employees and Transnet in terms of the effectiveness of the internal newsletter as a communication tool as well as their attitudes towards the newsletter as an information disseminating medium. A mixed methods approach was used for analysis in this study. The first methodological paradigm took an interpretivist approach, focusing primarily on analysing the content of the newsletter. The second methodological design was based on the positivistic theory approach and utilised a survey by questionnaire. One hundred and twenty (120) questionnaires were issued to Transnet Freight Rail employees representing the three regions: Central Region, Eastern Region & Western Region and the Head Office of which 120 (100 percent) were received back by the deadline. Of these respondents 56 (46,66 percent) said that they find Platform very relevant as an internal newsletter. A further finding was that 68,33 percent of the respondents said Platform should stay as it is. About 58,33 percent of the respondents took 30 minutes to an hour to read the newsletter with ratings of 72,5 percent interested in communication from management, 65 percent in financial performance, 60 percent in news about people and 59,16 percent in departmental information. The main types of information required are about updates on business performance and safety news. The content of six editions of the newsletter was analysed. The newsletter editions used were from the latest one published counting backwards. The content of the newsletter varies in each edition and depends on the theme. There are similar themes that come up with every edition such as safety. The style of writing used is simple to ensure maximum understanding.

Full textAbstract:
At Transnet National Ports Authority (TNPA), disagreement existed in terms of the role of human resources in performance management, which resulted in different role expectations and perceptions, often leading to conflict. An overview of existing literature reviewed that performance management was mostly presented from the view of line management, and that the role of human resources was not well defined. The purpose of this study was therefore to clarify the role of human resources in performance management, and with specific application at Transnet National Ports Authority. The purpose of performance management in Transnet is to influence each employee to perform optimally in his/her position by ensuring that each employee understands his/her role in the performance management process. A very important aspect of performance management is that it does not entail one activity only; it is part of the employee development life cycle in which the employee agrees with the manager on the expected performance of tasks, evaluation standards, tools required and important dates when performance will be formally discussed. The objectives of the study were achieved by means of a literature review. Following the literature review interviews were conducted with the Group Performance Manager, a line manager and a human resources practitioner at TNPA to get their views of performance management at TNPA and specifically of the role of human resources in performance management. The interviews, in addition to the literature study, also served as a basis for a survey questionnaire, which was used to probe the views of line iv management and human resources practitioners at TNPA on the role of human resources in performance management. The results of the interviews and the survey showed that performance management was not applied as a continuous and developmental process at TNPA, and that it was often perceived as punitive. The results also indicated that human resources at TNPA should be well versed in the use of the score card method and apply quality assurance in performance management. Recommendations were made for the role of line management and the role of human resources in performance management at TNPA, as well as for the relationship between the two parties.

Full textAbstract:
Numerous decisions in organisations are made by teams, groups or committees. The need for group decision making is brought about by the increased complexity of many decisions which require specialised knowledge in numerous areas usually not possessed by one person. As such there has also been an inherent recognition that different members bring different contributions and that a marshalling of these contributions enhances decision-making. Most research about how to make teams more effective has focused on identifying the task processes that distinguish the most successful teams - that is specifying the need for collaboration, involvement and commitment to goals. The assumption seems to be that, once identified; these processes can simply be imitated by other teams, with similar effects but it is not the case since they do not take the level of the team’s emotional intelligence into consideration. Emotional intelligence should always be considered in a team setting since teamwork is an inherently social activity and as such emotions play an important role in team processes including decision making. Surprisingly the study of the effects of emotions and emotional intelligence in decision making at group level is a relatively new research avenue. Research indicates that emotional intelligence has been the subject of a significant amount of literature for a number of years. However little has been contributed to how the behaviours associated with emotional intelligence may be practically applied to enhance both individual and group decision-making. Druskat and Wolff (2001a and 2001b) proposed a model for emotional intelligence at the group level. According to their model, groups develop a set of behavioural norms called the Group Emotional Competence Norms (GEC norms) which guide the emotional experience in groups. The proposed model by Druskat and Wolff was used to define and measure group emotional intelligence in this study. The aim of the study was to establish whether there was a relationship between team emotional intelligence and team decision making at Transnet Port Terminal’s Ngqura Container Terminal. The findings of the literature study and the empirical study were combined to evaluate whether team emotional intelligence affected team decision making in the chosen population.The literature study suggested that there was a relationship between team emotional intelligence and team decision making. The empirical study confirmed the relationship between group emotional intelligence and group decision making but failed to confirm whether the chosen population consisted of teams.

Full textAbstract:
Teams have increasingly become the means for completing tasks in many organisations, and organisations have turned to teams as a better way to use employee talents. Many South African companies have established work teams to solve both complex and minor problems, and some companies’ performance has increased due to the implementation of work teams. The fact that organisations are using teams does not necessarily mean they are always effective, there are many factors that contribute to team effectiveness in an organisation, and these factors need to be identified and managed properly so that the team can remain effective and produce the results that are expected. Management of most companies is unaware of the factors that contribute to group and team effectiveness, and most teams are ineffective because of the lack of focus on the factors that improve group and team effectiveness. This is the reason or objective why this study was conducted at Transnet Engineering, to identify the factors that are critical to improving team effectiveness. The researcher conducted a literature review in order to determine the factors that improve group and team effectiveness. Some of the factors deal with organisational culture, motivation (monetary and non-monetary motivation), diversity in teams, size of teams, formulation of teams, team leadership, team goals, team structures, team member training, trust in teams, etc. An empirical study with the use of a questionnaire was also conducted to determine the perceptions that supervisors, superintendents, foremen and managers have at Transnet Engineering with regards to factors that improve group and team effectiveness. The research instrument was grouped into five categories; organisational context, individual context, team context, management support and team effectiveness. More than 50 percent of the respondents agreed with the organisational and individual context factors that were tested, around 75 percent of the respondents agreed with team context factors that were tested, almost 60 percent of respondents agreed with management support factors, and more than 60 percent of respondents indicated that their teams are effective. Although there is general agreement between most factors identified in the literature study and the empirical study, the following will need more focus: Offering of team resources Leadership support from executive committee members (EXCO) Proper reward and recognition systems Conducting research to identify employee satisfaction levels Team development Diversity management Talent management Team size

Full textAbstract:
Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2017.<br>The balance between the dependency on Information and Communications Technology (ICT) and reducing costs has led to an increase in ICT outsourcing in many organisations. ICT outsourcing has benefits, but organisations have limited knowledge on information security and risks when outsourcing these functions. A lack of information security knowledge or a poor organisational risk culture carries the risk of project failure and security breaches. It is unclear how to manage information risks through the usage of ICT infrastructure risk management when outsourcing ICT projects, and this exposes organisations to ICT security risks. The aim of the study is to explore how a selected transport organisation can manage information risks through the usage of infrastructure risk management when outsourcing ICT projects.
Two primary research questions are posed namely, “what information risks does the ICT department manage when outsourcing ICT projects?”, and “how can the ICT department protect their information through the usage of infrastructure risk management against ICT security threats when outsourcing ICT?” To answer these two questions, a study was conducted at a transport organisation in South Africa. A subjective ontological and interpretivist epistemological stance has been adopted and an inductive research approach was followed. The research strategy was a case study. Data for this study was gathered through interviews (17 in total) using semi-structured questionnaires. Data collected were transcribed, summarised, and categorised to provide a clear understanding of the data.
For this study, forty findings and eight themes were identified. The themes are ICT outsourcing, information risks, costs, ICT vendor dependency, vendor access and management, risk management, user awareness, and frameworks. Guidelines are proposed, comprising six primary components.
The results point to gaps that need to be addressed to ensure that information is protected when outsourcing ICT projects. Measures need to be put in place and communication has to be improved among operating divisions. The findings lead to questions such as, ““how does business create an ICT security culture to ensure that information is protected at all times”, and “does vendor access management really get the necessary attention it requires?” Further studies on human behaviour towards ICT security is needed to ensure the protection of organisations against security risks.

Full textAbstract:
Social media is proving to be a critical factor for firms moving towards digital marketing strategies. Substantial economic advantage is gained when companies make use of social media platforms such as Twitter to modernise their businesses and start interactive communication with their target market. Social media can have a great impact on the efficiency and performance of state-owned enterprises, which are often plagued by information irregularities that compromise information disclosure and lower the standards of accountability within the state-owned enterprises. Without social media, customers are often unable to evaluate the product and services that the state-owned enterprise is offering before making an offer. An interpretivist research paradigm was adopted and informed this study which applied a mono qualitative research methodology. Sample elements were selected using non-probability purposive and convenience sampling techniques. Data was gathered through a pre-designed interview guide with open-ended questions from the research site. In addition, the case study research design was used in this study. All interview transcriptions were recorded with the aid of a voice recorder and exported to NVivo 11 for cleaning and coding, resulting in emerging themes. Thematic data analysis was performed on the data sets, allowing a detailed discussion of each theme in line with research objectives. The study established that adopting and using social media was the appropriate strategy for firms. Firms, especially state-owned enterprises, reached a larger audience. In addition, the study established that the quality of content uploaded and shared on social media should be of very high quality to project a positive image of the organisation. Appointing dedicated senior personnel to manage the social media strategy enhanced the effectiveness of social media. The study recommended that further research be conducted on other types of social media to allow organisations a wider selection of choices. The study indicated that employees were compelled to use Twitter; thus, a policy shift in the use of social media required managers to put in place Information Communications Technology and Privacy and Security Policies. In order to educate everyone in the organisation, management had to ensure that its policies did not infringe on human rights.

Full textAbstract:
Transnet is facing challenging market realities and a competitive operating environment. Performance management has been emphasised as a critical tool to guide Transnet in maintaining a competitive advantage. Performance management cannot be viewed in isolation from the organisational context and is inextricably linked to the Human Resources strategy, which in turn is aligned with the overall business strategy. Performance management may be defined as a systematic process by which an organisation involves its employees, as individuals and members of groups, in improving organisational effectiveness in the accomplishment of organisational mission and goals. For the purposes of this study, performance management was explored in terms of purpose, key role players, processes, criteria and challenges. The main research problem of this study was to determine the perceptions of non-bargaining unit employees of the performance management system at Transnet Engineering. The main research problem had three sub-problems which were addressed through the following actions: A literature study was conducted highlighting the importance of an effective performance management system which establishes a foundation for rewarding excellence by aligning individual objectives with organisational mission and objectives. In this way, performance management establishes clear expectations in terms of results, actions and behaviours. Through regular feedback and coaching, performance management provides a mechanism for detecting problems at an early stage and identifies ways in which to take corrective action. Perceptions of performance management are largely centred around fairness, and dependent on a number of issues, including openness, transparency, communication, and equitability, and the establishment of clear parameters of measurement such as whether both skill and effort will be evaluated. This is why it is important to link performance appraisals to employee goals. If mutually negotiated goals, which involve the participation of all stakeholders, are established at the beginning of the performance period and there is on-going feedback to employees about their performance, then performance appraisals may be perceived as objective, fair and reliable. The insights gained from the literature survey were incorporated into a survey questionnaire which was used in the empirical study to investigate the perceptions of non-bargaining unit employees of the performance management system at Transnet Engineering. This study revealed that most of the respondents were not satisfied with the performance management system within Transnet Engineering, that performance management could be enhanced by using multiple measures more frequently and that greater involvement of subordinates at each step in the performance management process would lead to a greater level of acceptance thereof.

Full textAbstract:
This research looks at Transnet a State owned Enterprise with a key focus on how it manages its non-core property assets that are currently highly dilapidated and in a poor state of repair with resultant sub-optimal returns being derived. The non-core property portfolio of Transnet is immediately visible, by way of comparison, of their deteriorating condition as opposed to those in close proximity or surrounding them that are privately owned. Transnet is a Freight and Logistics state owned company that owns huge tracts of prime and well located land countrywide that are not optimally utilized and also holds a large property portfolio consisting of predominantly 'D' grade buildings that are currently physically, functionally and economically obsolete lacking constant maintenance or engagement in redevelopments. Most assets were initially purpose built to support freight and rail logistics operations but have overtime become functionally obsolete due to changes in logistic chains operations, advancements in technology and nature of goods coming unto the railway system. The current study was aimed at assessing the reasons as to why the non-core property assets are physically deteriorated and achieving below market related returns. The study establishes a framework for optimal management of non-core property assets in Transnet, with literature review establishing the correct approach to issues impacting real estate management such as finance, maintenance and facilities management, property management structure and systems, legislative framework guiding SOE's and corporate governance. Theoretical models have made important contributions to the formalization of certain problems related to management of SOEs and the need to improve corporate governance with a lot of research done in SOEs in China and Europe in general. The key focus of this study was to establish the causes that have resulted in the noncore property assets being highly neglected and in a poor state of repair resulting in sub-optimal returns being achieved on portfolio. The results of the case study within a survey presented a divergent view of core property assets being better managed than non-core property assets. ii The research methodology undertaken was a survey within a case study. The case study is Transnet and the target respondents consisted of personnel involved in the direct management of core and non-core property assets within the company who were interviewed and questionnaires were also used to gather research findings data. The secondary data was analyzed using quarterly asset management data and benchmarked with Investment Property Data (IPD). The research findings present a comprehensive list of challenges faced by Transnet in the management of non-core property assets with the greatest impact being the Public Finance Management Act and National Government Immoveable Assets Management Act which clearly stipulates that when assets no longer serve the core business they must be disposed of. It is also clearly evident that funding cannot be granted for property development projects that are not aligned with the core business of Transnet which is freight and rail logistics. The study brings to the attention that capital investment and strategic decisions related to management of non-core property assets including legislation need to be reviewed. This will greatly shape the future of the non-core property business and its ability to manage its future operations financially viable and sustainable. Alternative sources of funding such as the Real Estate Investment Trusts on the Johannesburg stock exchange are other avenues that can be explored to raise capital funds for upgrading existing property portfolio or raising funds for property developments. The key focus on how the enterprise should behave, and what should be done is to make non-core property assets financially sustainable and viable for the business to achieve desired returns.

Full textAbstract:
This thesis examines the restructuring of the pension funds of Transnet, a South African state-owned company involved in transportation, from the 1990s. Two of its main pension funds, the Transport-Transnet Pension sub-Fund (TTPF) and the Transnet Second Defined Benefit Fund (TSDBF), have been surrounded by controversy, with major court actions brought by aggrieved pensioners in 2006-2012 and again from 2013, and smaller cases in 1997-1999 and 2004. (There were also a number of smaller cases, mostly unsuccessful, but the thesis will not examine them). The case that started in 2013 is the biggest class action in the country‟s history, and makes claims of serious mismanagement and bad faith against the Transnet management. But the fundamental grievance is that (according to the 2013 legal case) “more than 80% of pensioners earn less than R4 000.00 a month… 62 % earn less than R2 500.00… 45% of the pensioners earn less than the state‟s ordinary old-age pension” grant for the poor. Although that case is ongoing, this thesis examines the background and controversies that frame the case. It provides an overview of the history and development of the South African pensions system and South African state-owned companies; it examines how these have been shaped by the apartheid and post-apartheid periods, and by the rise of neo-liberalism; it examines the evolution of Transnet and its pensions systems, from the early days of the South African Railways and Harbours Administration (SAR&H, formed 1910), to its restructuring into the South African Transport Services (SATS) in 1982, and then into Transnet in 1990. The thesis shows that the operations of the TTPF and TSDBF, which are closed to new members, have had serious effects on pensioners that rely upon them. Pensions are very low (the main reason for the various court cases), and this is for a range of reasons. Annual increases in pensions are formally set at below-inflation levels, leading to falling real incomes. More pressure on pensioners‟ livelihoods has arisen from Transnet‟s cuts to other benefits, like the medical aid Transmed, provided to pensioners. While the schemes are solvent, the pensions generally started at a low base, partly because most pensioners were relatively poorly paid workers before retirement (and the pensions were linked to former salaries). There is also a racial dimension: while most white workers at SAR&H/ SATS and Transnet were poorly paid, black, Coloured and Indian workers were paid even worse, and, further, were only brought into the pension schemes late. Both TTPF and TSDBF are defined benefit funds, which means members are guaranteed specific benefits at retirement, with the employer obligated to inject funds to meet shortfalls where needed. Yet neither the state nor Transnet has been willing to take actions to lift the basic pensions, such as investments into the funds, or to make systematic ex gratia payments to bring the pensions to a reasonable level, to remove historic racial inequalities between pensioners, to increase medical aid co-payments or coverage or to otherwise address the pensioners‟ situation. It does not seem that the reason for the problems is that the two funds have been severely mismanaged or asset-stripped, as alleged in the 2013 class action: it must be noted that both funds report surpluses. But the surpluses are possible because the pensions are low and falling in real terms, and the numbers of pensioners declining due to deaths. It seems clear that Transnet is unable or unwilling to act to decisively improve the situation of the pensioners: ensuring a surplus on existing pension funds is a major goal. This is partly because Transnet itself has ongoing financial problems, and partly because it operates in the context of neo-liberal restructuring, like corporatisation, commercialisation and privatisation, which places limits on the additional funding of the funds. At the same time, the pensioners have very little real, as opposed to a nominal, say in the administration of the pension schemes, limiting their ability to affect the rules and administration or raise issues. The thesis seeks to use historical institutionalism, which sees policies and major institutions, including state-owned companies, as shaped by power and conflict, especially between classes. This is used to try and explain changing state policies and the changing role and actions of state-owned companies, as a way of understanding Transnet‟s actions, as well as its treatment of its pensioners.

Full textAbstract:
With the advent of the new high Tc superconductors, liquid nitrogen will be one of the preferred cryogens used to cool these materials. Consequently, a more thorough understanding of the heat transfer characteristics of liquid nitrogen is required. In our investigations we examine the transient heating characteristics of liquid nitrogen to states of nucleate and film boiling under different liquid flow conditions. Using a platinum hot wire technique, it is verified that there is a premature transition to film boiling in the transient case at power levels significantly lower than under steady state nucleate boiling conditions. It is also shown that the premature transition can be reduced or eliminated depending on the flow velocity.

Thesis (MBA (Business Management))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: Transnet, the entity responsible for port infrastructure and the operating thereof, are faced with the difficult task of ensuring that the port system in South Africa is always ready to cater to all import and export requirements of the country. A major portion of these volumes will enter and leave the country in the form of containerised cargo, which effectively unitises the cargo for easier handling. What makes the task for Transnet that much more difficult, is that volumes are not easily forecasted and when one takes into account that ports need to be looking at least ten years down the line to ensure infrastructure can be put in place in time, it makes the problem that much more difficult. International studies show that trade between India, Europe and South America are growing, which provides South Africa with the opportunity to become a hub port based on the countries central location between these three areas. Currently Durban and the recently opened port of Ngqura are and will be serving as hub ports to cater for these and other volumes, but it is not certain under what conditions there would be a need for an additional hub port, if at all. Through the course of this research report three scenarios of growth are examined in an effort to answer this question.<br>AFRIKAANSE OPSOMMING: Transnet, die entiteit verantwoordelik vir hawe-infrastruktuur en die werking daarvan, is met die moeilike taak geplaas om te verseker dat die hawe-stelsel in Suid-Afrika altyd gereed is vir al die invoer en uitvoer vereistes van die land. 'n Groot gedeelte van hierdie vereistes sal die land betree en verlaat in die vorm van houers, wat goedere unitiseer vir makliker hantering. Wat die taak vir Transnet soveel moeiliker maak, is dat die volumes nie maklik geskat kan word nie, en wanneer Transnet ten minste tien jaar in die toekoms moet skat om seker te maak dat die infrastruktuur in plek kan gestel word in tyd, maak dit die probleem soveel moeiliker. Internasionale navorsing dui dat die handel tussen Indië, Europa en Suid-Amerika groei, wat vir Suid-Afrika die geleentheid skep om 'n ‘hub port’ to word wat gebaseer is op die land se sentrale ligging tussen hierdie drie lande. Op die oomblik sal Durban en die onlangs geopende hawe van Ngqura, as ‘hub ports’ funksioneer om voorsiening te maak vir hierdie en ander volumes, maar dit is nie seker onder watter omstandighede sou daar 'n behoefte vir 'n ekstra-hub port wees nie. Deur die loop van hierdie navorsing word verslag gelewer van die drie scenario's, en word hierdie vraag ondersoek in 'n poging om hierdie vraag te beantwoord.

Prior to the adoption of the Labour Relations Act 66 of 1995 (LRA), the Constitution of the Republic of South Africa, 1996 (Constitution) and subsequently the Promotion of Administrative Justice Act 3 of 2000 (PAJA), public sector employees were at an immense disadvantage since they did not enjoy the same benefits which accrued to private sector employees under the then Labour Relations Act 28 of 1956. Unfortunately an overlap was inadvertently created by these Acts, particularly with regard to employment related disputes in the public sector. As a result courts have long grappled with the question as to whether or not public sector employees could rely on administrative law principles in employment related disputes.
This dissertation examines the relationship between the LRA, PAJA and the Constitution and specific reference is made to the Constitutional Court's judgment in Chirwa v Transnet Ltd & Others [2008] 2 BLLR 97 (CC). It notes the conflicting judicial decisions on the overlap between the LRA and PAJA and the subsequent applicability of PAJA in public sector employment disputes.
The dissertation notes the difficulties in excluding PAJA in its entirety and whether it will be feasible for the LRA to surpass the applicability of PAJA, given the role of both labour law and administrative law in South Africa's constitutional dispensation, with their constitutionally entrenched international obligations in mind. In this regard, the author advances some proposals in relation to the best way forward on dealing with this complex interplay by keeping the minority judgment handed down in Chirwa at the forefront.<br>Thesis (LL.M.

<p>Cargo transfer between two vessels at sea requires the ramp connection between the vessels to be as stable as possible. The complex nature of the system makes employing control methods difficult. This thesis explores two ideas for improving performance of the interconnected system. First idea examines the possibility of actuating the smaller of the vessels with fins, so as to reduce the relative movement between the two points where the ramp is connected to the ships. The second idea using the larger ship to shield the smaller one from incoming waves. It is assumed that the total disturbance is minimized at a certain angle to the waves, and an Extremum-Seeking based controller is used to find this angle. To allow ship models to change dynamically as cargo offloads, the technique of extremum seeking is extended in this thesis to allow a certain type of model uncertainties.</p>

Full textAbstract:
In the presented thesis work, meshfree method with distance fields was extended to obtain solution of nonlinear transient heat transfer problems. The thesis work involved development and implementation of numerical algorithms, data structure, and software. Numerical and computational properties of the meshfree method with distance fields were investigated. Convergence and accuracy of the methodology was validated by analytical solutions, and solutions produced by commercial FEM software (ANSYS 12.1). The research was focused on nonlinearities caused by temperature-dependent thermal conductivity. The behavior of the developed numerical algorithms was observed for both weak and strong temperature-dependency of thermal conductivity. Oseen and Newton-Kantorovich linearization techniques were applied to linearized the governing equation and boundary conditions. Results of the numerical experiments showed that the meshfree method with distance fields has the potential to produced fast accurate solutions. The method enables all prescribed boundary conditions to be satisfied exactly.

Full textAbstract:
Includes bibliographical references.<br>This thesis is concerned with the numerical modelling of the transient nonlinear heat conduction problem in solid continua. The hyperbolic governing equation is specialised to a parabolic equation which is sufficient for most engineering applications. The theoretical development includes the effects of conduction, specific heat, internal heat generation and the boundary conditions of convection, radiation, specified temperatures and flux, as well as point sources in the domain. The finite element spatial semidiscretisation of the equations is formally derived from the weak form of the governing equations. Temporal discretisation is obtained through an implicit/explicit difference scheme. The material properties are allowed to be temperature dependent, and consequently a modified Newton-Raphson iterative scheme is employed to solve the equations. The fully discretised equations are solved by implementing the algorithm in an existing finite element stress analysis code. Modelling is possible using four or eight-noded isoparametric elements, and solution control is possible through choice of time step size and choice of time integration method. Five examples are employed to demonstrate the ability of the program. The results compare well with published analytical solutions.

Full textAbstract:
In public transport, seamless coordinated transfer strengthens the quality of service and attracts ridership. The problem of transfer coordination is sophisticated due to (1) the stochasticity of travel time variability, (2) unavailability of passenger transfer plan. However, the proliferation of Big Data technologies provides a tremendous opportunity to solve these problems.
This dissertation enhances passenger transfer quality by offline and online transfer coordination. While offline transfer coordination exploits the knowledge of travel time variability to coordinate transfers, online transfer coordination provides simultaneous vehicle arrivals at stops to facilitate transfers by employing the knowledge of passenger behaviours.

En utilisant les spectroscopies d'absorption UV-vis et d'émission stationnaire et résolue dans le temps (femto- et sub–nanoseconde, caméra à balayage de fente), nous avons étudié, au cours de cette thèse, les processus photophysiques au sein de différentes molécules et supramolécules. Les propriétés photophysiques de nouveaux complexes de Ru(II) polypyridine et de Ir(III) cyclométallé présentant un transfert d'énergie électronique réversible entre le noyau métallique et les chromophores organiques auxiliaires énergétiquement appariés (anthracène et pyrène) ont été analysées en détail.

Approved for public release; distribution is unlimited.<br>The heat transfer along the axis of a pulse detonation combustor has been characterized for various frequencies and fill fractions at 2.5 atmospheres of pressure for chamber refresh conditions. In a pulse detonation combustor, a supersonic detonation wave is the method for transforming chemical energy into mechanical energy and the wave propagates much faster than the subsonic flames in devices such as rockets and ramjets. The flow field inside a pulse detonation combustor is highly turbulent, unsteady, and varies largely during each combustion cycle. By determining the heat transfer properties at multiple axial locations and the associated combustor wall temperatures, proper combustor material selection can ensure the material properties will not deteriorate and therefore allow for practical operational lifetimes. Experimental testing measured the axial heat transfer characteristics in a pulse detonation combustor at various operating conditions and multiple cooling jacket locations. Computer simulations were used to model the heat transfer inside the pulse detonation combustor and correlate those predications with empirical data. The acquired data from the comparison of the computer simulations and the experimental results was correlated and demonstrated good agreement. The determined values should allow designers the ability to consider regenerative fueling strategies for future systems.

Full textAbstract:
Braking is mainly controlled by the engine. Friction between a pair of pads and a rotating disc converts the kinetic energy of the vehicle into heat. High temperatures can be reached in the system which can be detrimental for both, components and passenger safety. Numerical techniques help simulate load cases and compute the temperatures field in brake disc and brake pads. The present work implements a Finite Element (FE) toolbox in Matlab/Simulink able to simulate different braking manoeuvres used for brake dimensioning mainly in the early phase of car development process. The brake pad/disc geometry is considered as an axisymmetric body assuming negligible temperature gradient along the circumference of the disc. Calibration using three control factors namely: heat coefficient during braking , acceleration and emissivity for the implemented thermal model is performed using experimental investigation at Volvo Car Corporation (VCC) for three specific severe load cases. The thermal model is extended to measure brake fluid temperatures to ensure no vaporisation occurs. Simulation results of the brake disc and brake pad show good correlation with the experimental tests. A sensitivity analysis with the control factors showed convective coefficient during acceleration the most sensitive, with temperature change of around 16%.

Full textAbstract:
This dissertation presents a system-wide approach, based on genetic algorithms, for the optimization of transfer times for an entire bus transit system. Optimization of transfer times in a transit system is a complicated problem because of the large set of binary and discrete values involved. The combinatorial nature of the problem imposes a computational burden and makes it difficult to solve by classical mathematical programming methods.
The genetic algorithm proposed in this research attempts to find an optimal solution for the transfer time optimization problem by searching for a combination of adjustments to the timetable for all the routes in the system. It makes use of existing scheduled timetables, ridership demand at all transfer locations, and takes into consideration the randomness of bus arrivals.
Data from Broward County Transit are used to compute total transfer times. The proposed genetic algorithm-based approach proves to be capable of producing substantial time savings compared to the existing transfer times in a reasonable amount of time.
The dissertation also addresses the issues related to spatial and temporal modeling, variability in bus arrival and departure times, walking time, as well as the integration of scheduling and ridership data.

La demande énergétique de l’humanité augmente rapidement et ne montre aucun signe de ralentissement. Parallèlement à cette problématique, l'utilisation abusive de combustibles fossiles est l'une des principales causes d'augmentation de la concentration de CO₂ dans l'atmosphère. Ces problèmes doivent être résolus en termes de limitation des émissions de CO₂ et de recherche de sources d'énergie renouvelables pour remplacer les combustibles fossiles. De nos jours, l’énergie solaire est l’une des sources d’énergie renouvelables les plus efficaces. La conversion de l'énergie de la lumière solaire en électricité dans le photovoltaïque ou en énergie chimique par le biais de processus photocatalytiques implique invariablement un transfert d'énergie photo-induit et un transfert d'électrons. Dans ce contexte, l'objectif de la thèse est d'étudier les processus photo-induits dans les photosystèmes moléculaires utilisant la photolyse par flash laser. Le premier thème de cette thèse porte sur l’étude du transfert monoélectronique dans des systèmes de dyades donneur-accepteur en vue d’optimiser l’efficacité de la séparation des charges et de son application dans la cellule solaire organique photovoltaïque. Le deuxième thème de cette thèse porte sur l’étude de deux systèmes modèles de photosynthèse artificielle étudiés pour la possibilité d’une accumulation de charge par étapes. Ensuite, différents systèmes photocatalytiques, développés pour la photoréduction du CO₂, ont été étudiés. La compréhension des processus photo-induits devraient permettre l’amélioration de l'efficacité de la réduction du CO₂ dans les systèmes photocatalytiques pratiques<br>The energy demand of humanity is increasing rapidly, and shows no signs of slowing. Alongside this issue, abuse using fossil fuels is one of the main reasons which leads to an increase in atmospheric CO₂ concentration. These problems have to be solved in terms of both limiting CO₂ emission and finding renewable energy sources to replace fossil fuels. Nowadays, solar energy appears as one of the most effective renewable energy sources. Conversion of solar light energy to electricity in photovoltaics or to chemical energy through photocatalytic processes invariably involves photoinduced energy transfer and electron transfer. In this context, the aim of the thesis focuses on studying photoinduced processes in molecular photosystems using laser flash photolysis. The first theme of this thesis focus on studying single electron transfer in Donor-Acceptor Dyad systems towards optimization efficiency of charge separation and application in the photovoltaic organic solar cell. In the second theme of this thesis, two model systems of artificial photosynthesis were investigated to assess the possibility of stepwise charge accumulation on model molecules. A fairly good global yield of approximately 9% for the two charge accumulation on MV²⁺ molecule was achieved. Then, different photocatalytic systems, which have developed for CO₂ reduction, were studied. Understanding of the photoinduced processes is an important step toward improving the efficiency of reduction of CO₂ in practical photocatalytic systems

Full textAbstract:
The dynamic response of a packed bed to a pulse of heat input has been studied to provide estimates of the axial dispersion coefficient, fluid-particle heat transfer coefficient, intraparticle thermal conductivity and particle heat capacity. Packings of spheres and cylinders of different material and size were investigated. The dynamic response found in experiment was compared with the dynamic response calculated for the same inlet perturbation by numerical analysis of the partial differential equations for the fluid-phase dispersion model including intraparticle conduction. The fluid-phase dispersion model was used in the analysis as unlike other models it has been subjected to statistical tests which showed its validity and its consistency over a wide range of experimental results. The method of analysis of beds of spheres was the Alternating Direction Implicit Method and it has been given in an earlier study. This method was then developed to the Alternating Phase Implicit-Explicit Method to enable its application to beds of cylinders. A Bayesian approach was followed in parameter estimations. In this approach prior information and information provided by the experimental run were combined to give mean posterior values of the four heat transfer parameters together with estimates of their accuracy. The Bayesian approach adopted in this study was also applied to resolve the parameter interaction which existed between the axial thermal dispersion and the heat transfer coefficient, two parameters which were found to be highly correlated.

Full textAbstract:
Free liquid-jet impingement is well researched due to its high heat transfer ability and ease of implementation. This study considers both the steady state and transient heating of a patterned plate under slot-free-liquid jet impingement. The primary working fluid was water (H2O) and the plate material considered was silicon. Calculations were done for Reynolds number (Re) ranging from 500 to 1000 and indentation depths from 0.000125 to 0.0005 m for three different surface configurations. The effect of using different plate materials and R-134a as the working fluid were explored for the rectangular step case. The distributions of the local and average heat-transfer coefficient and the local and average Nusselt number were calculated for each case. A numerical model based in the FIDAP computer code was created to solve the conjugate heat transfer problem. The model used was developed for Cartesian coordinates for both steady state and transient conditions.
Results show that the addition of surface geometry alters the fluid flow and heat transfer values. The highest heat-transfer coefficients occur at points where the fluid flow interacts with the surface geometry. The lowest heat-transfer coefficients are found in the indentations between the changes in geometry. The jet velocity has a large impact on the heat transfer values for all cases, with increasing jet velocity showing increased local heat-transfer coefficients and Nusselt number. It is observed that increasing the indentation depth for the rectangular and sinusoidal surfaces leads to a decrease in local heat transfer whereas for triangular patterns, a higher depth results in higher heat-transfer coefficient. The transient analysis showed that changing surface geometry had little effect on the time required to reach steady state. The selection of plate material has an impact on both the final maximum temperatures and the time required to reach steady state, with both traits being tied to the thermal diffusivity (α) of the material.

A measurement-based reduced-order heat transfer modeling framework is developed to optimize cooling costs of dynamic and virtualized data centers. The reduced-order model is based on a proper orthogonal decomposition-based model order reduction technique. For data center heat transfer modeling, the framework simulates air temperatures and CPU temperatures as a parametric response surface with different cooling infrastructure design variables as the input parameters. The parametric framework enables an efficient design optimization tool and is used to solve several important problems related to energy-efficient thermal design of data centers.
The first of these problems is about determining optimal response time during emergencies such as power outages in data centers. To solve this problem, transient air temperatures are modeled with time as a parameter. This parametric prediction framework is useful as a near-real-time thermal prognostic tool.
The second problem pertains to reducing temperature monitoring cost in data centers. To solve this problem, transient air temperatures are modeled with spatial location as the parameter. This parametric model improves spatial resolution of measured temperature data and thereby reduces sensor requisition for transient temperature monitoring in data centers.
The third problem is related to determining optimal cooling set points in response to dynamically-evolving heat loads in a data center. To solve this problem, transient air temperatures are modeled with heat load and time as the parameters. This modeling framework is particularly suitable for life-cycle design of data center cooling infrastructure.
The last problem is related to determining optimal cooling set points in response to dynamically-evolving computing workload in a virtualized data center. To solve this problem, transient CPU temperatures under a given computing load profile are modeled with cooling resource set-points as the parameters.

heat loss to the ambient is controlled by means of thermal
insulation, which is
designed for steady state operations. During shutdowns,
the stagnant fluid in the

reaching some critical
temperature. As a result, several problems can occur, such
as formation of
hydrates or deposition of high molecular weight paraffins
on the inner wall of the
subsea line, which can lead to flow line blockage and
production shutdown. Restart
of very viscous fluid after shutdown is also critical,
since viscosity increases
significantly with the reduction of the temperature. This

of the influence of the pipe wall thermal capacitance on
the transient behavior of
heavily insulated lines. The heat loss from the pipeline
is determined, by solving
the transient heat conduction equation for the pipewall
layers, utilizing a simple
one-dimensional model in the radial direction. The finite

employed to solve the transient flow inside the pipeline,
from the time instant that

Hydrodynamics and heat transfer characteristics found in fluidization were studied in a small scale laboratory fluidized bed. Experiments were designed to capture field data on multiple slit jet gas distributor systems for the validation of computational models. Localized data was quantified through the use of several novel non-intrusive experimental measurement techniques. The analyses provide a unique study that connects full field-of-view multiphase flow dynamics with transient heat transfer distributions.
The gas-solid hydrodynamics were captured through three non-invasive measurement techniques, viz. Particle Image Velocimetry (PIV), Digital Image Analysis (DIA), and pressure drop spectral analysis. The effects of inlet gas flowrate, Geldart B and D classified particle types, and the number inlet gas slit jets were investigated. Frequency analysis of a differential pressure signal resulted in the classification of four difference flow regimes. The coupling of PIV with DIA captured particle velocity, solid circulation rates, average cycle times, dead zone sizes, jet merging effects, gas void fraction distributions, and maximum expanded bed heights.
The heat transfer in fluidized and spouted beds containing a heated inlet gas source was studied through transient heat transfer measurements and analyses. Innovative experimental procedures were introduced to quantify bed-to-wall and gas-to-particle heat transfer characteristics. Two techniques were developed to overcome the spatial, time varying, and instrumental intrusive limitations often found in multiphase flow heat transfer studies. Infrared thermography was utilized along with derived discrete differential equations, and an inverse heat conduction analysis to solve for transient localized heat flux profiles and heat transfer coefficient distributions. As a result new data containing increased spatial resolution is presented on gas, wall, and particle temporal maps. Computations based from the thermal gradients quantified bed-to-wall heat flux profiles, gas-to-particle heat transfer coefficients, and localized rates of energy stored.<br>Master of Science

En utilisant ces approches numériques, nous présentons les résultats pour plusieurs types d’écoulements non-stationnaires, de gaz raréfiés monoatomiqueset de mélanges binaires de gaz monoatomiques<br>A gas inside the microsystems or the porous media is in its non-equilibrium state, due to the fact that the molecular mean free path is comparable to the characteristic dimension of the media. The same state of a gas, called rarefied, is found at high altitude or in the vacuum equipment working at low pressure. All these types of flow can be described by the kinetic models derived from the Boltzmann equation. This thesis presents the development of the numerical tools for the modeling and simulations of the rarefied gas flows. The two models of the full Boltzmann equation, the Shakhov model (S-model) for the single gas and the McCormack model for the gas mixture, are considered. The discrete velocity method is used to the numerical discretization in the molecular velocity space and the TVD-like scheme is implemented in the physical space. The main aspect of this work is centered around the transient properties of the gas flows and, especially, on the transient heat and mass transfer behaviors. However, for some configurations only steady-state solutions are considered and the implicit scheme is developed to reduce the computational cost. Using the proposed numerical approach several types of the transient rarefied single gas flows as well as the binary mixture of the monoatomic gases are studied

Thesis (MPhil)--Stellenbosch University, 2005.<br>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.<br>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.

Date: 11 October 2016<br>This research investigates Transnet‟s Foundry Quality System, focusing on the quality issues in the Foundry. This includes determining the total cost of quality for the business, investigating the impact of the specific defects on the productivity of the business. Two products were analysed namely, the top centre casting and the brake shoe holders.
Root cause analysis was done on each stage of the Foundry process to understand the causes of defects. Data was collected and analysed and most of the defects that occur were found to be the result of poor quality management which consequently causes low productivity and low profits. Also identified was a lack of skilled personnel in specific areas in the Foundry. Furthermore data collection as part of the quality system in the Foundry is not effectively executed and this implies that performance cannot be fully measured.
Non Compliance reports from customers were analysed and the total cost of quality was calculated to be R1 214 690.73 based on the data that was available. The impact of defects on productivity was also analysed for the financial year 2014/2015 and it was calculated to be 47% for the brake shoe holders. The target for the Foundry for the financial year was R4 048 799.30 for the actual productivity in sales amounted to R 1 915 510.60. For the top centre the estimated target for the financial year 2014/2015 was R6 271 500.00 and the actual productivity amounted to R3 305 250.00. Statistical process control charts were drawn and it was discovered that some of the machines owned by the business are not capable of producing to specification. Qualifound was identified as a framework to improve the Transnet foundry quality system.
It is recommended that top management be educated in the concept of cost of quality and its impact on business profitability and that skilled quality coordinators be appointed to facilitate continuous quality maintenance.<br>MT2017

D.Phil.<br>The strategic change process that the South African Transport Services, South Africa's largest transport undertaking, had to undergo with its transformation into Transnet Limited in April 1990, was one of the most extensive any undertaking in South Africa had yet to go through. Central to the change process was the transformation of the company from an "undertaking of the State" to a commercialised/privatised entity. The process is characterised by three phases viz. deregulation, commercialisation and possible future privatisation. This discontinuous change process affects every aspect of the company, in particular the Human Resource processes thereof. Against this background an extensive theoretical conceptualisation of change management was devised from a modernist perspective. A model was developed describing the WHY, the WHAT, the HOW (process and micro-dynamics) and the WHO of the change process. Human Resource Management was identified as Human Resource Provision, Human Resource Maintenance, Human Resource Development, Labour Relations, Equal Opportunities/Affirmative Action and Social Investment. This dissertation is the result of an extensive diagnostic exercise on micro-level within Transnet to ascertain what the perceptions of Transnet employees are towards cardinal Human Resource variables. These variables were identified against the background of Human Resource theory and deemed as critical for the successful strategic change of Human Resources in Transnet. Against this background, problem areas could be identified, the readiness of employees to change could be scientifically measured and the overall "fit" of employees with the changing conditions could be ascertained. A test sample of 1 875 employees of all employee groups in Transnet (excluding the general group) was taken. The sample was spread out over ten regions of the country. The practical research was done in conjunction with the HSRC in September 1991 - roughly 18 months after Transnet was formed amidst an extensive process of commercialisation. An effective response of 60% was achieved. All statistical processing and analyses were done at the HSRC's computer centre in Pretoria. To make sense out of the mass of information, a factor analysis was done. Two main factors were identified in a second order analysis - one factor which was construed as broad Human Resource Management/Social Investment and a second as broad Labour Relations/Equal Opportunities. The main finding of the research was evidence of an entrenched Human Resource system and that a gap exists between aspects of Transnet's mission and the practical realisation thereof and perceptions of employees on the work floor. A participative culture has not yet been formed while additional problem areas were identified as the management style of the company, employees' motivation, discrimination, work organisation and individual relations, work security and upward mobility. An extensive strategic change model was conceptualised out of these findings so that problem areas could be addressed and managed effectively. Due to the diversity of Transnet's work force a second model, namely a typological model, was devised. The model was conceptualised after further statistical analysis (MANOVA/ANOVA) was done. Accordingly, further problem areas were identified around population group, language, region and occupation.

133, [5] leaves<br>Project Management is the wave of the future. This discipline and its evolution continues to be one of the principal means by which operational and strategic changes are managed in the enterprise. The importance of Project Management for organisational success will expand, rather than wane, in years to come.
Projects, particularly large scale complex ones with multiple stakeholders, are failing at alarming rates despite a wide spectrum of efforts to solve the problem. The lack of meaningful results and outcomes is due, in part, to the fact that organizations tend to operate on a set of unproven assumptions concerning project objectives, business requirements, user expectations, motivations, agendas, schedules, costs and time frames.
The management dilemma is that Transnet has committed R 65 billion to projects in the hope of developing its core businesses to that of world-class standards as a logistics service provider in South Africa. Transnet’s capital project division, Protekon, is responsible for managing the projects committed to this R 65bn capital expenditure.
Transnet’s perception of Protekon’s failure to successfully deliver projects could result in appointments of external consultancies such as Hatch McDougal and Guba (HMG – an engineering consultant firm). Whereas, previously, Protekon was the monopoly service provider of engineering and project management skills within Transnet, Transnet’s sub-divisions appear to be utilizing outside consultancies more frequently. The reason for procuring engineering and consultancy services external to Transnet, among others, is the perception that Protekon is performing poorly in delivering successful projects. The outsourcing of work, fuelled by the negative perception of Protekon’s performance, directly impacts on the profitability of Protekon in the short to medium term.
The objective of this dissertation was firstly to investigate the effect of Protekon’s involvement in Transnet’s project success; and secondly, to recommend strategies to improve the rate of project success, that could be applied within Transnet and Protekon.

M.Com. (Business Management)<br>Affirmative action is extremely topical in South Africa today, not only in terms of business principles but among individuals and communities as well. Since the establishment in the late 1850's of the South African Railways and Harbours and it's eventual change to the present-day Transnet, a "white" culture was constantly being established. For the past number of years Transnet is engaged in bringing about a culture change to transform the company into an equal opportunity company. The purpose of this study is to describe the the full meaning of affirmative action in Transnet and to put the importance of such action for both the Company and it's employees into perspective. The methods used by Transnet to apply affirmative action with the least possible resistance and interruption of business are also discussed. In Transnet affirmative action is part of a process known as the tum strategy. Through a personal interview with the Group General Manager (Human Resources) of Transnet the origin and implementation of the turn strategy is explained. The tum strategy consists of thirteen substrategies that must be completed before the exercise can be called a success. The success of the turn strategy could rest on the evaluation and monitoring of the results of the substrategies. A spirit of co-operation between Management and organised labour was achieved by involving both parties as members of the Turn Strategy Council. The Turn Strategy Council is responsible, inter alia. for monitoring the turn strategy. In conclusion specific findings and recommendations are made. Although it may be necessary to make adjustments to suit local circumstances, the value of the study is in the opportunity it affords other companies/organisations to use Transnet's model to implement affirmative action.

Project failure continues to be a concern even though standards and procedures have been in place for years to counteract the issue. Many reasons for the high rate of project management failure have been purported in the research literature (Bauer, 2006; Hammoud, 2008 & Kerzner, 2002). This study analyzes the problem of high failure rate of major capital projects within Transnet Freight Rail. In addition to reviewing research literature that addresses projects failure concepts, critical success factors, project management principles, strategic alignment, skills and capabilities of project managers and how these factors might relate to major capital projects failure, the study will examine possible problems at the organizational and functional level that might be contributing to the high failure rate of major capital projects within TFR.<br>Graduate School of Business Leadership<br>M.B.A.

D. Litt. et Phil.<br>The white paper on privatisation and deregulation in the Republic of South Africa, was tabled in 1987. This paper outlined a policy for the possible privatisation of state-owned enterprise. Generally this step was favourably met by "Big Business" and a number of political players, but rejected and resisted by the Congress of South African Trade Unions (COSATU). This phenomena led to the central assumption of this study. It was assumed that the rejection of privatisation (or manifestations thereof, such as commercialisation) by COSATU, would not necessarily be indicative of the cognitions and attitudes which labour union employee members, hold of privatisation/commercialisation. The purpose of this study was to explore this assumption. This assumption was to be researched among a sample of official members of the South African Railway and Harbours Workers Union (SARHWU); an affiliate of COSATU. A further purpose was to explore the influence which an official communication action, (aimed at the employees of a commercialised parastatal), may have had on the cognition and attitude of the sample. The aim was to draw from these findings to formulate directives for the internal strategic communication management of commercialisation to black SARHWU members. To achieve this purpose, the concept privatisation and commercialisation were conceptualised, and fundamental differences between the two concepts highlighted. An extensive "theoretical study was undertaken to identify the communication principles on which the communication of innovation (change) are based. The concepts of privatisation/commercialisation and the principles of the communication of innovation, were integrated into a framework for the formulation of a communication strategy and strategic communication plan for commercialisation.

Precisely and timely cash flow and information flow are its identity. Although commerce could be done on internet, goods can’t be transferred through the internet by present technology. Shops need to deliver goods to consumers through logistics system. The efficiency and availability of logistics system depend on logistician can use tools which like logistics vehicles, carts and Auxiliary systems efficiently or not. The industry use both motorized vehicles (truck, motor scooter) and non-motorized vehicles (cart, dray) as delivery equipment for now. Therefore, Because Taiwan is a highly urbanized community many narrow alleys are hard to reach by the vehicle currently being used. In this study we use this background as our motivation and want to know if there are any possible to develop an auxiliary accessory for improving the working environment of logisticians by our profession. We care also contribute to the community.
According to Innovation and New Product Development method, this study can be separated into 4 stage: (1) the first stage is identifying opportunities. Through data collection and interviewing major delivery industry executives and drivers which includes industries from northern, central and southern Taiwan. After further understanding, we found that improving existing 4 wheel cart is a positive suggestion; (2) the second stage is understanding opportunities. Conduct STEEP and analyze product opportunity gap. STEEP is a modern STEP analyze which can analyze product trend in external environment or in internal policies. By integrating the interviewing into the results, we can find out the relationship between product and product opportunities. An initial innovative concept will generate. The concept can be put into the third stage; (3) the third stage is conceptualize opportunities. By collecting opinions from target users to clarify whether the concept is appropriate or not; (4) the fourth stage is realizing opportunities. Using the result from 3 stage above to correct the initial concept. Through Innovation and New Product Development method, we can design a product which truly fit the environment and care users. The product also can make a positive influence to environment and community.
After the analyzing, we found that specific product functional requirements in concepts get more attention from target users. In 11 design features, there are 4 needs correction. There are no significant difference in abstract product satisfaction. Only in northern area have higher satisfaction to “power”. Because northern area has a heavier business volume, they have a greater need to Auxiliary power of dray. In the last, using 3D modeling to present the innovation concept design which has been improved.
