Using System Simulation to Compare the Performance of Different Dispatching Rules - A Case Study of a Stone Enterprise in Taiwan

Abstract

It takes plenty of processes to manufacture daily construction and decorative material from nature marble which is obtained from open cast quarries and nature From these manufacturing process marble cutting spends lots of time Regarding the overall production throughput and the schedule of customers’ order which is within time limit I conduct this research on the problem and try to solve the bottleneck of production line Dispatching rule plays a significant role in the production flow It decides the priority of each process Traditionally dispatching rule is based on experience and current order information However this rule makes a decline in profits because of not finishing specific process in time and the marble would be damaged This research is to solve marble dispatching problem and using Arena Simulation Software to build up the procedure model for marble manufacturer Besides it considers for the different dispatching rule and compares with each result to find out the optimal solution In the conclusion the study shows Stone Size method is the most appropriate for dispatching rule based on the normal factory production plan and order schedule There are some advantages To begin with Stone Size method can reduce the consumption of saw blade Then it can efficiently reuse the tool and reduce the cost Finally the total profit can be the biggest Besides Stone Size method if the product is high value of timeliness the study also shows another method (First in First Out) spends less cost and time because it doesn’t need to do permutations and combinations
