In Line Balancing principles, the total workload in the assembly process is divided as evenly as possible among the workstations, without violating the sequences and relations in the assembly operations. Line balancing is important in an assembly system as it balances the line and increases the efficiency, as well as the productivity of a system. A case study was conducted in the assembly line of an electrical accessories manufacturer in Malaysia. The cycle time for each station was recorded, and the standard cycle time was estimated. The productivity, as well as the efficiency of the current assembly line, were studied. In terms of the productivity, the performance of the current systems was 500 units/worker/day, while the expected productivity was 600 units/worker/day. An assembly line setting was proposed based on the Line Balancing Method; the productivity for the proposed line increased to 671 units/worker/day, or in rough additional increase around 34%.

Abstract Social, economic, and technological recent developments leading companies to face new production challenges. Companies will need physical and virtual structures allowing cooperation and quick adaptation along all value chain. To this matter, one of the main foundations of industry 4.0 is the use of information and communication technologies systems. Many companies are using information and communication systems without integration with business partners and even also with internal departments. This gap needs to be analyzed and it can be made by measuring the status of the industry 4.0 enabling technologies adoption inside a company using maturity or readiness models transmitting knowledge and pathing initiatives to help on progress and monitorization, looking forward to the future status of the internal value chain. On a qualitative and quantitative matter, this study presents the industry 4.0 enabling technologies readiness level of three departments of an automotive company internal value chain. This case study shows different readiness level on each department and limitations to reach better levels such as potential results if the benefits of industry 4.0 enabling technologies were reach on a company that assumes to be aligned with the industry 4.0 strategy.

The construction sector plays an important role in a country’s economic development. The financial performance of a company is a good indicator of its financial health and status. In Malaysia, the government encourages the construction industry to develop an advanced infrastructure related to health, transport, education and housing. In view of the COVID-19 pandemic, the operations and financial performance of construction sector companies have been affected recently. Additionally, uncertainty plays a vital role in the multi-criteria decision-making (MCDM) process. Based on previous studies, there has been no comprehensive study conducted on the evaluation of the financial performance of construction companies by integrating entropy and fuzzy VIKOR models. Therefore, this paper aims to propose an MCDM model to evaluate and compare the financial performance of construction companies with an integrated entropy–fuzzy VIKOR model. A case study is carried out by evaluating the listed construction companies in Malaysia with the proposed model. The findings of this paper indicate that the company ECONBHD achieves the best financial performance over the study period. The significance of this paper is to determine the priority of the financial ratios and ranking of the construction companies with the proposed entropy–fuzzy VIKOR model.

All companies strive towards lowering their manufacturing costs. Few companies do however succeed in continuously improving their production after the launch of a new production process. This article introduces a method for companies having an established technology to optimize their production in terms of part cost without disrupting the normal, day-to-day production. By incrementally chancing the process parameters such as for example cutting data as a function of the originally selected values, it is possible to optimize the production process. This is closely related to the lean production philosophy and long term sustainability which strives towards efficient use of resources and involvement of all employees in improving the production process. In the case study presented in this article it was found that by adding extra sulfur to the cutting fluid it was possible to decrease the part cost. By using the proposed method the company was able to decrease the part cost when manufacturing a specific part with approximately 5 %.
