Abstract:
The concepts of Lean Supply Chain, Just-in-time and Kanban System influenced to apply in the industrial sector. The purposes of this research are; 1) to study a current raw material feeding process 2) to study the process with the Kanban system and 3) to provide a comparison of time and cost incurred between both systems of car accessories company. The two of participant observation tools are applied for gathering primary & secondary data. The comparative analyzing is used for population in 7 product groups. The results of the research in the current process show that the standard cycle time of the raw material issuance is 60 minutes per cycle, with 352 times of the issuance is 21,120 minutes and having direct labor cost 33,440 Baht. The results of the research in the process with Kanban system show the issuance time can be reduced by 6 minutes or 10% through eliminating the hand-written form. Moreover, the emergency issuance will be 100% eliminated, make only 248 times of the issuance is 13,392 minutes and having direct labor cost 21,204 Baht. The comparative analysis results between both systems show time consuming is lower 7,818 minutes or 36.59% and direct labor cost incurred is lower 12,238 Baht or 36.59%.
