Thematic data analysis was used to analyse the data collected from managers and specialist IT staff. The assessment revealed that the main organisational adoption readiness barriers were the lack of a formal green IT policy, an unclearly defined green IT governance framework, and a lack of green performance management. The main drivers of adoption were economic imperatives and regulatory and ethical requirements. Interestingly, a contextual variable – an exogenous shock caused by COVID-19 and the robustness of the organisation’s crisis response during the pandemic – rapidly increased the rate of green IT adoption at the firm.

Thus brickyards seek to reduce the amount of waste to increase productivity and reduce cost overruns. In this study, the problem that has the greatest economic impact on a brick company is the excessive amount of waste. For this reason, the implementation of a model based on the Lean Six Sigma (LSS) methodology is proposed, applying Poka Yoke, Jidoka, Standardised Work, and Just in Time in order to reduce the number of defective bricks and cost overruns. The research project focused on the tambourine brick, the type whose percentage of generated waste is the highest in the production batch. To do this, the current situation was analysed; the main causes of the problem were identified and measured; and then Lean Six Sigma tools were used to attack the root cause. Finally, the proposed design reduced overheated bricks by 2.36%, wet bricks by 2.01%, and poorly stacked bricks by 1.8%, obtaining a 6.92% reduction in shrinkage and increasing the level of Six Sigma to 3.9, which contributed to the reduction of losses in the brickyard.

However, maintenance causes infrastructure to be taken out of service, which impacts traffic flow. In this study, the requirements of a maintenance possession scheduler for a South African application were investigated and a proposed solution was developed. The main objective of the scheduler was to minimise the deviation of the train service on a subset of rail infrastructure while ensuring that the required maintenance was done. An application case – the railway infrastructure between Bellville and Wellington in the Western Cape province of South Africa – was identified. A novel mixed-integer linear programming model that could do possession scheduling for 24 hours on a microscopic level was formulated for this case, and implemented in the software Cplex, after which it was validated. Finally, several experiments were conducted to investigate the model’s performance and the results. It was found that the model delivered optimal results in less than nine minutes, which makes it a feasible maintenance possession scheduler for day-to-day work in the immediate planning horizon.

The Six Sigma improvement method mainly uses quality control and statistical methods to improve product quality, so as to reduce the cost and waste caused by defective products. Taiwan is the world leader for original equipment manufacturing in the laptop industry, and related peripheral accessories are also a major concern of customers. The subject of this study was a professional supplier of laptop batteries. Through the collection of customer complaint data, it was found that battery case deformation was the most important problem for customers. Therefore, in order to remain competitive, the battery case deformation problem needed to be overcome first. Enterprises need to improve their existing processes to reduce the rate of product defects, improve output efficiency and product quality, and reduce production costs, so as to improve their competitiveness in the industry.This study took a Taiwanese company as an example to improve the plastic injection process through the improvement steps of Six Sigma. In this process, two key process factors, namely the injection speed and the cooling time, were identified by analytical tools. After calculating customers’ daily product demand, the most suitable parameters were found using the ‘design of experiments’ method. The results showed that the process capacity and product yield could be significantly improved. The key to the success of this Six Sigma project was the project implementer’s design of the experiment.","PeriodicalId":49493,"journal":{"name":"South African Journal of Industrial Engineering","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135001983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The regulation and application processes are as much a challenge in South Africa as they are elsewhere. The number of drones is growing at a rapid pace, and there is a need to improve the current status to benefit from the technology. The purpose of this paper is to evaluate the South African drone industry and to propose recommendations to enhance drone technology in South Africa. The research design applied in this paper was qualitative. Data was collected by interviewing drone operators who were interested in participating in this study. This was done to understand the drone approval process in South Africa and the perceptions of drone operators. The results indicated that commercial drone operators are being negatively impacted by the drone approval structure in South Africa and that it is holding the industry back. Key factors affecting the existing drone approval structure were identified and used to propose the strategies for improvement. The findings in this study could assist stakeholders in the South African drone industry to make effective decisions and to formulate policies that would promote the technological growth of the industry.

An Initial survey confirmed that only 56.86% of respondents agreed that INDI 4.0 accurately measured readiness in manufacturing operations. Unlike the primary I4.0 indices, INDI 4.0 lacks comprehensive I4.0 dimensions and characteristics. This paper aims to identify the dimensions and indicators of I4.0 readiness to enhance INDI 4.0 through an exploratory mixed-method research approach with a multiphase research design. The first phase consisted of a qualitative approach through a documentary review, interviews, and observations to explore the dimensions and indicators of I4.0 readiness. This phase successfully identified four dimensions that experts, academics, and practitioners validated: technology, data life cycle, I4.0 design principles, and smart factory. These dimensions were broken down into 27 indicators of I4.0 readiness, then validated again through a statistical approach before being affirmed by a survey with a Pearson’s correlation > 0.361 and Cronbach’s alpha of 0.987, which indicated validity and reliability. The second phase, using a quantitative approach through a survey, confirmed the four dimensions and 27 indicators for measuring I4.0 readiness levels; these were ‘not ready’, ‘early stage’, ‘moderate readiness’, ‘readiness ripe’, and ‘already implemented’. This finding comprehensively measured I4.0 readiness based on feedback from industries struggling to adopt I4.0, especially in developing countries such as Indonesia. This finding also differed from existing indices (Acatech, RAMI 4.0, Dreamy, SIMMI 4.0. IMPULS) from developed countries and industries already stable in implementing I4.0. eywords: (Industry 4.0, I4.0 readiness indicators, INDI 4.0)","PeriodicalId":49493,"journal":{"name":"South African Journal of Industrial Engineering","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135001994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
