SIMULATION SYSTEM OPTIMIZE THE TIME OF PROCESS

Abstract

PT. LTX is a company engaged in manufacturing that produce tin plate coil form. Coil packaging process needs to be done before it is sent to the customer. In the process of packaging the coil is found on the machine appender bottleneck causing measurement stations of diameter and wrapping coil to be delayed which makes the time coil packaging is not optimal. This study aims to determine the simulation model of the existing coil packaging process, determining the proposed improvements to optimize the timing of coil packaging process, as well as find out the time optimal coil packaging process. This study uses a software simulation with ProModel 7.5. ProModel simulation results showed that the average time coil packaging process for 657.81 hours per month, so that made three design alternatives and the best improvement is the third alternative with the addition of resources such as forklifts and additional mounting stations crown that yield an average of 315.296 hours per month.
