Application of SMED Methodology and Scheduling in High-Mix Low Volume Production Model to Reduce Setup Time: A Case of S Company

Abstract

Nowadays rapid changes in consumer demand determines the production model. The demand for "single and large quantity" products has gradually turned into a "high-mix and low volume" product demand. The main problem of high-mix low volume model is significantly increasing frequency of set up, causing an increase in set-up time for production. For set-up reduction strategies, Shingo (1985) proposed single minute exchange of die (SMED) methodology. The SMED methodology makes it possible to reduce setup (changeover) operations time within 10 minutes. Therefore, in this study take a cable processing company as a case for improvement. The potential of faster setup cannot be completely achieved with SMED method. So, in this paper, it also provides an optimized scheduling reference indicator for the molding machine that decision makers to determine the sequencing rule of scheduling by each criterion through the system to achieve maximum benefit for company.
