Improving lead time of pangasius fillet production process based on value stream mapping: a case study

Abstract

Value stream mapping (VSM) is one of the critical tools to identify waste ful steps in the production process and help build the future VSM by applying lean production system innovations. This research aims to identify wastes in non-value-added pangasius fillet lines at GEPIMEX 404 based on lean tools. Firstly, the article explores the company’s production process, builds the current value chain map, and identifies the wastes. Then, the authors use Kanban cards to ensure quality and output, eliminating inventory of semi-finished products in the production line. Next, the authors develop a future VSM and simulate the production process using Arena software to verify the effectiveness after proposing improvements. Finally, the results showed a significant step towards reducing production time from 7.59 to 4.96 hours.
