The automotive manufacturers are trying to manage production by introducing the Digital Virtual Manufacturing (DVM) or the Digital Virtual Factory(DVF) simulation technology and unitary Supply Chain Management(SCM) systems in order to provide product quickly that consumers desire. However, it is difficult to introduce by small supplier except for car-maker or Tier 1 in cost, manpower and time. In this study, The Target is Tier 2 and Tier 3 or small supplier. Using the TimePrism which is work-analysis and work-improvement tool based on recording video with the QUEST(QUeuing Event Simulation Tool, Dassault Systems DELMIA D5 Solution) which is process analysis Simulation software, we developed and set up the methodical process analysis process which is usable when small supplier installs the assembly product line of the automotive part for pilot or production and we evaluated effectiveness in respect of methodology application by validating in practice.
