Abstract

This research presents a study and an approach to improving the productivity of the fresh corn silage production process at a silage factory in Sukhothai province through computer simulation modelling. The proposed simulation program is called flexsim, which generated a prototype model. This prototype was compared with five alternative models to enhance productivity. Based on the analysis of the experimental results, the prototype model, designed to simulate the current production process of the factory, revealed poor machine utilization for large machine, with an idle time percentage of 75% and a processing percentage of 25%. After adding a raw material amount of 25,000 kilograms into the simulation model, it was found that the second scenario could reduce the machine idle time by 17.5% and increase output from 10 units per day to 17 units per day compared to the present operation. From the results, it can be concluded that the case study factory does not need to invest the money to improve the productivity by purchasing new machines.
