Abstract

This project focuses on improvement and improvisation of a manufacturing line by using Total Productive Maintenance concept as tools to help reduce the amount oflosses due to machine breakdown and other blockage during production. The main objective of this project is to reduce the frequency of breakdown in order to avoid losses to scrap and also to increase internal supply chain performance in a given four month period. The methodology of this project consists of visual observation of the actual production line and at the same time doing the time study to help find out the waiting time for any bottleneck point and variability effect.. Manufacturing simulation software WITNESS also has been used in order to find the number ofthroughput in a controlled condition and shortest time possible. From that three models were developed to ensure every parameter is considered before taken into the real operation. Input data for the simulation is attained from real data from copper wire factory. Model 1 is generated based on reliability analysis, model 2 is focused on queuing theory and waiting time and model 3 is based on buffer flexibility. The model is generated to target time of four month time using WITNESS software.. The breakdown problem in model 1 has been reduced from 40 breakdowns per month to 25 breakdowns per month which is about 37.5% reductions. The total throughput from model 2 yield 16800 kg of copper wire compared to normal model which yield 8400 kg in a basis of four month. Model 2 is preferable to be use in real production base on highest throughput yielding and considerable amount of breakdown per month.
