The Improvement of fireproof suit by using line balancing techniques case study : creative polymers co.tld

Abstract

The purpose of this research were to 1) study the production factors and efficiency of fireproof suit; 2) analyze the three line balancing models of fireproof suit; and 3) make comparison of production efficiency for fireproof suit’s manufacturing processes. A group of representative sample for assessments is 90 dressmakers of Creative Polymers Co., Ltd. The used tool for collecting data is the data recoding form, consisting of production process list, data recording date, processing operation, and duration of processing. Accordingly put the sewing line layout and make production test with the three line balancing models of fireproof suit, then record all data and entry all data to SPSS program to average statistics on percentage and standard deviation. The research showed that the improvement of the three line processing models of fireproof suit, comparing to the data of the three line balancing models are identified that C model increased from traditional production system 74.05 percentage, B model increased from traditional production system 57.51 percentage, then A model increased from traditional production system 48.53 percentage. The result showed that the fireproof suit’s production processing of Creative Polymers Co., Ltd. ought to take the C model, in order to fasten production process and augment better quality. A minimum process of producing is amount of 110 steps with less time per one unit; minimum 177.41 minutes; with 30 workers; and 27 machines. The waste product of the three line processing models: A, B, and C model; not over 20 percentage during 8 hours of working. It shows that the c model has the least of waste product. The over operation that product has not much wasted, not include in choosing the model for improving production efficiency and C model
