- Description: Abstract: Inventory management system that aims at managing, controlling and storing of the spare parts is a cost driver for aerospace equipment in operating and maintaining those equipment. During those breakdowns, maintenance personnel spent too much time trying to find and acquire replacement parts. Requisition volume depends on instinctive feel and past experiences, with some casual meeting with the maintenance technicians manufacturing designers and specialists. Consequently, the concept of inventory management systems has become a buzz word amongst the scholar and industry practitioners. Despite the fact that, the concept of inventory management system in aerospace is attending higher level of significance within the western countries, America and Asia due to its ability of smoothing the business environment, in Africa, particularly in south Africa, the integration and adoption of inventory management system in aerospace is facing several challenges. To date, over the past decades a huge number of studies have been conducted with the aim of investigating the benefit of inventory management implementation in manufacturing as well as Aerospace industry at global level. However, very few studies have been conducted from South African aerospace industry level. Hence, the overall goal of this paper is to fill this gap by means of critically analyzing studies that were developed various inventory management frameworks over the past decade.

- Description: Abstract: Regardless of the overhaul outages planned with the aim of preventing failures on the energy plants in South Africa, it is witnessed not to be effective based on the production ratio outcomes. The production ratio as per the South African power enterprise is 80:10:10. The ratio is based on 80 % availability, a fixed 10% planned maintenance and 10 % unplanned maintenance. Consequently, the concept of preventative maintenance has become a buzz phrase amongst scholars and industry practitioners, even though, preventative maintenance is attaining a higher level of significance in well developed countries, such as America and China due to its ability to smoothening the energy sector. In Africa, particularly in South Africa the integration and adoption of the concept of preventative maintenance is phasing challenges. To date, over the past decades several studies have been led to investigate the benefit of preventative maintenance implementation in the energy sector at global level. However, very few investigative studies concerning the implementation and adoption of preventative maintenance in the South African energy generation sources have been conducted, hence the overall objective of this paper is to fill this gap by means of critically analyzing studies that were conducted or developed in the field of preventive maintenance over the past two decades. The outcome of the analysis of the existing literature on preventative maintenance clearly illustrates that there are flaws in the current body of knowledge related to a lack of sufficient studies in the context of South African electricity sector.

- Description: Abstract: Lean production has a potential to strengthen the competitive advantage of the companies. As the airline business sector proceeds to quickly extend and advance; the current aircrafts management is facing a challenge of having to balance the long term goals with short term answers. Satisfaction of the clients has turned out to be altogether critical for airline operations and this resulted to more focus on the service quality. Lean's client centered topic for enhancing service quality has picked up a drive in services; but, the implementation of Lean in this industry is way behind health and manufacturing services. Although a number of studies have been conducted over the past few decades to address these issues but there is still a gap in the current literature review, therefore the aim of this paper was to theoretically assess the lean implementation in airline industry. The results of the critical analysis of the current literature clearly indicate that there are flaws related to the country and area of the studies. Most of the studies are based in UK and USA and the previous researchers have focused more on manufacturing companies.

- Description: Abstract: Inadequate spare parts stock or inventory leads to wind tunnel facilities unavailability and loss of revenue if the wind tunnel subsystem or equipment fails and cannot be repaired or replaced immediately. At the point when the extra part is required however missing in stock, it must be requested from a provider. This causes the operational downtime relying upon the lead time of the extra part. On the other hand, inventory management which handling, controlling and storage of the spare parts is a cost driver for wind tunnel facilities in operating and maintaining wind tunnels. During wind tunnel breakdowns, maintenance personnel spent too much time trying to find and procure spare parts. Requisition amount depends on gut feel and past experiences, with some casual conference with the maintenance technicians and specialists. Although the number of studies have been conducted in the past two decades to address this issues, therefore the aim of this paper is to theoretically assess the theoretical assessment framework of inventory Management System in wind tunnels and the results of the critical analysis of the current literature clearly demonstrates that there are flaws in the current body of knowledge related to the effectiveness of inventory management in the aerospace industry, especially in wind tunnel facilities and also few of those studies concentrated on spare parts inventory management.

- Description: Abstract: As a major sector contributing to economic development, the construction industry also has substantial impacts on the environment and society. There are numerous environmental issues derived from construction activities such as outdoor and indoor environmental pollution, greenhouse gas emission, and influences on the ecological environment. As a response to these contests, the shift of the construction industry from the traditional paradigm towards more balanced development among the economic, social and environmental dimensions, i.e. sustainable development, has received global attentions. Even though many studies have been conducted on sustainable manufacturing, the critical assessment conducted in this study posits that there is much gap to be covered as far as research in this filed is concerned. Considering this gap, this study aimed at theoretically assessing sustainability in construction sector. The results of the critical appraisal of the current literature, clearly illustrate that there is a gap in the current body of knowledge particularly with SMEs. These can feed in future endeavours of crafting a framework for sustainable manufacturing for construction industry SMEs.

- Description: Abstract: Products with low quality, long lead time, and limited variety are no longer acceptable among customers due to the drastic change in the global market during the past years. Customers’ demands are increasing by time and traditional production systems cannot meet this new level of demand. Hence, applying new production methods in order to produce high quality product, in short time, with low price becomes essential for survival in current competitive global market. Lean manufacturing is one of the approaches which has been used by many companies around the world to achieve these competitive advantages. However, lean manufacturing as a competitive advantage tool has not fully been implemented in the food manufacturing industry. Although numerous studies have been conducted over the past decade to address this issue there is still a gap in the current literature. Therefore, the aim of this paper is to theoretically assess status-quo of lean manufacturing. The results of the critical analysis of the current literature clearly demonstrate that there are flows in the current established body of knowledge related to various industry such as the food industry and the small and medium enterprises.

- Description: Abstract: Due to the fast growth of renewable energy resources, the analysis and comparison of costs associated with different forms of electricity generating sources are crucial for decision policy makers and investors. To this end, the Levelized Cost of Electricity (LCOE) is a widely tool employed to assess the economic viability of a power plant, however the issue with this tool is that it does not considers all the complexities involved. Thus, the Levelized Avoided Cost of Electricity (LACE) has been introduced to cover the elements ignored by LCOE, which are becoming critical to business decision. Despite the development of LACE, various studies continue using LCOE to evaluate the economic competitiveness of various power plants, especially in South Africa. To this end, this paper used both LCOE and LACE tools assess and compare the economic viability of 10 technologies which are: coal, gas, nuclear, biomass, geothermal, hydroelectric, wind offshore, wind onshore, solar photovoltaic, concentrated solar power. The results indicate that of all technologies, geothermal ranks at the first place as the most economic competitive alternative, followed by coal technology. Furthermore, the results illustrate that the worse technologies in terms of economic viability are solar photovoltaic, concentrated solar power, and wind. As far as the authors are aware this study is the first example in the context of the South African energy sector.

- Description: Abstract: Construction in many nations is one of the prevalent industries that uses both skilled and unskilled labor, as well as providing an opportunity for seasonal employment of various age groups. Construction work is a major component of all infrastructure and industrial development, such as buildings, highways, airports, railroads, hospitals, schools, housing, dams, irrigation systems, etc. With increasing growth in the construction industry, the construction business has become a competitive environment in recent years. To keep up with this competitive challenge, organizations throughout the world employ many factors, such as public-sector awards, profits derived from changes instead of sticking to the initial bid, access to state-subsidized financing, and preference for constructors who employ unionized workers, among others. One of the main factors for firms to consider in such a competitive environment is the need to strike a balance between the level of end-product quality and concomitant expenses. The increasing costs of material supplies and wages greatly impact construction activity costs, thus raising expenditures for businesses and organizations. Although a number of studies have been conducted over the past two decades to address these issues, there is still a gap in the current literature review. Therefore, the aim of this paper was to theoretically assess studies on the cost of poor quality in different sectors. The results of the critical analysis of the current literature clearly demonstrates that there are flaws in the current body of knowledge related to the choice of company size and the research methodology used.

- Description: Abstract: Regardless of the overhaul outages planned with the aim of preventing failures on the energy plants in South Africa, it is witnessed not to be effective based only on the production ratio outcomes. The production ratio, as per the South African power enterprise is 80:10:10. The ratio is based on 80 % availability, the only fixed figure of 10% planned maintenance and 10 % unplanned maintenance of the power plants. The production ratio on most South African power station is not close to the above mentioned ideal ratio as witnessed on some stations whereby the station’s ratio is recorded at 55:10:35. Overhaul maintenance on equipment are ideally rolled out as a failure preventative measure to prevent unplanned maintenance and thus ensure satisfactory availability of the power generating plant. In this paper, we illustrate the effectiveness and benefits of maintenance operations or strategies. Although numerous studies have been conducted over the past two decades to analyze effectiveness of maintenance strategies, there remains a gap in the current overview. Therefore, the objective of this paper is to conduct a theoretical assessment on the effectiveness of overhaul maintenance in the energy sector. The results of the critical analysis of the current literature on the subject matter, clearly demonstrates that there are flaws in the current body of knowledge related to a lack of boiler and quantitative studies.

SME industry is an exceptional industry for the fact that large percentage of construction sectors it’s possible to categories them as small as well as Medium sized Enterprise (SMEs). This study assesses how applicable the ERP is to construction industry. It as well estimates a manuscript founded on enterprise data techniques as well as mirrors it to ERP via the case revision of segmental household industrialist.

Assumed that assembling took place by the use of Commercial off the Shelf Software (COTS), this as well may need the not as much of awareness as well as information technology skills from the operators, decreasing the upskilling the economic importance too. Founded on the information, the script founded technique looks as feasible substitute to ERP for the construction sector. Although a number of studies have been conducted over the past two decades in order to address these issues, but there is still a gap in the current literature review, therefore the aim of this paper was to theoretically assess, the status quo of ERP implementation in small and medium enterprise. The results of critical analysis of the current literature clearly demonstrate that there are gaps related to lack of exploring the SME.

- Description: Abstract: The rapidly increasing advancements in manufacturing sector has created pressure for manufacturers to rethink and redesign their existing systems in order to cope with the challenges that emerged with globalization and environmental concerns. This trend brought about the introduction of the sustainable manufacturing concept; this concept of sustainable manufacturing is generally referred to as “green business” which emerged towards the end of the 20th century. An increase in customer awareness and pressures from stakeholders shifted manufacturers' focus; no longer were financial benefits the primary concern in the contemporary business environment. As a result, many innovative strategies were brought into the realm of manufacturing systems, such as lean, green, agile, and sustainable manufacturing practices. Sustainable manufacturing has been acclaimed in recent years for its significant benefits directed at triple bottom line factors (social, environmental, and financial) also known as the sustainable development pillars. Even though many studies have been conducted on sustainable manufacturing, the critical assessment conducted in this study posits that there is much gap to be covered as far as research in this filed is concerned. Considering this gap, this study aimed at theoretically assessing sustainability in food manufacturing SMEs. The results of the critical appraisal of the current literature, clearly illustrate that there is a gap in the current body of knowledge particularly with SMEs. These can feed in future endeavours of crafting a framework for sustainable manufacturing for food manufacturing SMEs.

- Description: Abstract: Growing pressures from various players such as governments, non-governmental organizations, and customers have impelled business corporations to address the economic, environmental, and social issues associated with their supply chain activities. Consequently, the concept of sustainability has become a buzzword among scholars and industry practitioners. Although, the concept of sustainability is attaining high level of importance in Europe, America, and Asia due to its ability of ensuring environmental sustainability, in Africa the integration and application of sustainability’s concept is facing several challenges. To date, several studies were conducted to investigate the barriers affecting sustainability practices in mining sector at country’s level. However, an investigative study regarding the barriers of sustainability practices in mining sector of the Southern African Development Community (SADC), which involve fifteen African countries is missing, this paper aims at filling this gap. The data were collected through a quantitative approach. At least 1 423 participants were involved in the survey. The findings revealed that the major barriers blocking the development of Sustainable Supply Chain in mining industry of SADC region include Lack of commitment on environmental deterioration, lack of communication and knowledge sharing, Ineffective monitoring and control system, lack of effective policy and legislation direction, high cost associated with the implementation of SSCM, Poor Supplier Commitment, lack of green practitioners, poor senior managements’ commitment, lack of recycling activities. Lack of Political commitment and support, Lack of managerial support and practical tools, and inadequate individual capacity.

- Description: Abstract: Over the last decade, South Africa has been experiencing an electricity supply crisis. This power crisis has been threatening the stability of the national power grid. The crisis was caused by insufficient generation capacity as well as an increased demand for electricity. In order to counteract this situation, the state owned electricity utility, Eskom decided to increase its power capacity by building new power plants, and implementing demand side management (DSM) initiatives to save energy. All of this came at a cost. Therefore, the present study was aimed at helping decision makers in the South African electricity sector to decide on the optimum funding allocation for the above projects. The research methodology adopted in this study was cost analysis. Three levels of cost comparison were developed in this study. These were based on power generating technologies (coal, gas, nuclear, wind, concentrated solar power, and solar photovoltaic), and on DSM programmes (residential mass rollouts, standard offer programme, standard product programme, performance contracting programme, and energy services companies model mass rollouts). The first level analysed the costs of building power plants as well as costs of producing electricity using different power generating technologies. The second level analysed the costs of implementing DSM programmes as well as costs of saving energy by implementing DSM programmes. Lastly, the third level analysed the costs of building power plants against the costs of implementing DSM programmes, as well as assessing the costs of producing electricity versus the costs of saving energy. The results for both power plants and DSM measures were tested through sensitivity analyses. At the first comparison, it was revealed that renewable energy technologies have the highest costs, higher than other generating technologies. At this level, a conclusion was drawn up in three parts noting that (1) although renewable technologies are expensive, they should be given more weight due to the fact that they are inexhaustible, (2) they guarantee safety to the environment, and (3) they do not emit greenhouse gases into the environment. At the second level of cost comparison, it was demonstrated that residential mass rollout (RMR) has the highest cost, higher than any other programme. At this level, it was concluded that due to the target market of RMR, which is residential sector, RMR should be given more weight, because more energy is wasted in this sector. It was further observed that residential consumers use a lot of electricity during peak period, and this increases during the winter season. The third level of cost comparison demonstrated that DSM measures were the resource alternative available at the lowest cost to the electricity utility. Hence, DSM initiatives could help to alleviate power outages issues and therefore, delay the need for building new power plants. Since DSM initiatives were found to be cheaper to run, their implementations meant that the utility would save billions of Rand by not using large amounts of water, coal, fuel, operating the plant at lower levels of intensify and doing less maintenance on the power plant. , M.Ing.
