Abstract
Purpose –This paper aims to analyze the Thai sugar industry supply chain and investigate the use of Value Stream Mapping (VSM) to identify waste. Design/methodology/approach – VSM is the main tool used to identify opportunities for improvement and elimination of waste in processes. Then, this paper proposes an approach to improve the sugar supply chain. Findings – The results of current state map found that non-value-added and necessary non-valueadded activities, which are waiting times, took 735 minutes, representing 56.84% of production time. An approach sequencing and scheduling arrival of sugar cane trucks proposes to improve the sugar supply chain in the future state map. Simulation results that eliminate waiting time associated with non-value-added activity save 185 minutes, reducing non-value-added activity to 49.19% of production time. Research limitations/implications – The findings are limited due to the focused nature of the case study. Originality/value – This paper is a real case study showing VSM applications and simulation approach sequencing and scheduling arrival of sugar cane trucks to eliminate waste in the process. In future research, this approach will be applied to reduce non-value-added activity in the Thai sugar industry.
