Nowadays, according to constant changes in the manufacturing style of products, there arises a requirement for rearrangement of facilities. The way how facilities are laid out might cause bottleneck or not in production processes, and decides production efficiency. Therefore, reasonable layout of facilities is a very important problem in factories to be newly built or already built.
Generally, layout of facilities is based on mathematical modeling and optimized planning. However, its complexity fails to meet the requirements of developing modern production modes.
Paek Chol Yong, a researcher at the Faculty of Automation Engineering, has proposed a reasonable layout of facilities. Deciding that the layout of facilities in the machining workshop is a typical discrete event system, he conducted a simulation of the layout of existing facilities by using FlexSim to find its disadvantages and eliminate bottleneck phenomena.
Then, he applied the proposed layout method to a workshop. As a result, the productivity increased by 1.15 times and the production time decreased by 1.21 times as much as the original layout of facilities.
