Increasing manufacturing complexity continues to be one of the most significant challenges facing the manufacturing industry today. Due to these rapid changes in manufacturing systems, one of the most important factors affecting production is recognized as the frequent production setup or changeovers, consequently affecting the overall production lead times and competitiveness of the company. Developing responsive production setup and process capability is increasingly important as product ranges and varieties in manufacturing companies are growing rapidly and, at the same time, production business models are operating more towards being customer-oriented. Furthermore, although different conventional methods have been used to manage complexity in production changeovers, sustainability and competitiveness development in a manufacturing company needs to be scientifically addressed by managing manufacturing complexity. In this paper, a sustainable manufacturing-oriented approach is presented in mind of managing manufacturing changeover complexities. A case study is carried out specifically concerning changeover complexity in a pharmaceutical company, aiming at minimizing complexities in production changeover and waste, increasing plant flexibility and productivity, and ultimately the sustainable competitiveness of the company in managing manufacturing changes.

PurposeIn recent years, many manufacturing companies are attempting to implement lean manufacturing systems (LMS) as an effective manufacturing strategy to survive in a highly competitive market. Such a process of selecting a suitable manufacturing system is highly complex and strategic in nature. The paper aims to how companies make a strategic decision of selecting LMS as part of their manufacturing strategy, and on what basis such strategic decisions are made by the managers.Design/methodology/approachA case study of a small‐ and medium‐sized enterprise is presented, in which the managers are contemplating on implementing either computer integrated manufacturing systems (CIMS) or LMS. To supplement the decision‐making process, a multi‐criteria decision making (MCDM) model, namely, the preference ranking organisation method for enrichment evaluations (PROMETHEE) is used to analyse how it will impact the stakeholders of the organisation, and the benefits gained.FindingsAn extensive analysis of PROMETHEE model revealed that LMS was the best for the given circumstances of the case.Research limitations/implicationsThe same problem can be extended by incorporating the constraints (such as financial, technical, social) of the organisation by utilising an extended version of PROMETHEE called the PROMETHEE V. Since, a single case study approach has been utilised, the findings cannot be generalized for any other industry.Practical limitations/implicationsThe methodology of PROMETHEE and its algorithm has been demonstrated in a detailed way and it is believed that it will be useful for managers to apply such MCDM tools to supplement their decision‐making efforts.Originality/valueAccording to the authors’ knowledge there is no paper in the literature, which discusses the application of PROMETHEE in making a strategic decision of implementing LMS as a part of an organisation's manufacturing strategy.

Manufacturing systems, in pursuit of cost, time and flexibility optimisation are becoming more and more complex, exhibiting a dynamic and nonlinear behaviour. Unpredictability is a distinct characteristic of such behaviour and effects production planning significantly. Complexity continues to be a challenge in manufacturing systems, resulting in ever-inflating costs, operational issues and increased lead times to product realisation. This challenge must be met with appropriate decision-making by manufacturing companies to secure competitive advantage without compromising sustainability. Assessing complexity realises the reduction and management of complexity sources which contribute to lowering associated engineering costs and time, improves productivity and increases profitability. Therefore, this study was undertaken to investigate the priority level and current achievement of manufacturing performance in Malaysia’s manufacturing industry and the complexity drivers on manufacturing productivity performance. The results showed that Malaysia’s manufacturing industry prioritised product quality and they managed achieved a good on-time delivery performance. However, for other manufacturing performance, there was a difference where the current achievement of manufacturing performances in Malaysia’s manufacturing industry is slightly lower than the priority given to them. The strong correlation of significant value for priority status was observed between efficient production levelling (finished goods) and finish product management while the strong correlation of significant value for current achievement was minimised the number of workstation and factory transportation system. This indicates that complexity drivers have an impact towards manufacturing performance. Consequently, it is necessary to identify complexity drivers to achieve well manufacturing performance.

PurposeThe purpose of this study is to explore reshoring drivers and barriers from a Swedish manufacturing perspective.Design/methodology/approachThis paper is a case study, including four Swedish manufacturing companies, with focus on drivers and barriers from the context of the Swedish manufacturing industry. A literature review of previously established drivers and barriers is used to map out the empirical findings and thereby identify potential gaps between the current body of literature and drivers and barriers from a Swedish manufacturing context.FindingsThe findings of the study suggest that quality issues continue to be one of the strongest reshoring drivers. Except for product quality, quality is also connected to host country’s infrastructure, communication and service. The supply chain perspective is a source of several drivers and is identified as a perspective often overlooked in offshoring decisions. Barriers related to firm specifics were more elaborately discussed by the companies, especially concerning calculation of location decision and the need to invest in resources, which allows for a higher level of capacity at the home country facility.Research limitations/implicationsThe study develops a structured table of reshoring drivers and barriers which can serve as a base for future research. Future research on the calculation of location decisions is deemed as a crucial step to further understand reshoring and aid companies in the decision-making process.Practical implicationsThe drivers and barriers identified in the study can give practitioners insight into reshoring from the perspective of the Swedish manufacturing industry and thus aid in future manufacturing location decisions. The table of drivers and barriers can also be important to understand how Sweden can strengthen its competitive advantage and motivate more companies to reshore manufacturing.Originality/valueThis is one of only few papers from the Nordic countries and also one of few case studies examining reshoring in manufacturing companies.

Manufacturers tend to carry out certain important and continuous activities with respect to internal operations which could contribute to their success. These activities are termed organization critical activities (OCAs). The main objective of this study is to elicit the OCAs in the manufacturing industry to understand what can cause them to be successful. Through the case study approach including the interviews with the senior managers from three manufacturing companies in Taiwan and a series of prioritizing activities, 12 OCAs have been identified. This study found that Taiwanese manufacturers placed more importance on the activities of quality and cost control while placed relatively less importance on the marketing related activities. More findings and future research suggestions are also provided.
