시뮬레이션 기반 식품 제조 공정 개선 연구

The fresh food manufacturing process is labor-intensive that usually requires careful manual operations from raw materials to produce merchantable consumer food products. In particular, the manufacturing processes of Kimchi which is a traditional Korean side dish usually consist of highly manual operations except material handling processes. Workers of a Kimchi manufacturing line, in general, are not allowed sufficient time to complete their work units in order to keep the freshness of final food products. This paper presents a simulation based approach to improve the salting process of vegetables that generates a semi-final product of Kimchi. We apply ANOVA to sort out bottleneck processes, and then we improve these processes using RSM to determine reasonable parameter values of manufacturing equipment.
