THIS PAPER PRESENTS A CASE STUDY OF APPLYING SIMULATION AS BOTH A DESIGN TOOL AND AN OPERATIONS PLANNING TOOL FOR A NEW AUTOMATED FLEXIBLE MANUFACTURING SYSTEM FOR THE ASSEMBLY, TEST, AND PACKOUT OF COMPUTER WORKSTATIONS. BOTH STATIC (SPREADSHEETS) AND DYNAMIC SIMULATION HAVE BEEN FOUND TO BE USEFUL IN DIFFERENT PROJECT PHASES. DYNAMIC SIMULATION RESULTS ARE PRESENTED. THE PAPER CONCLUDES THAT DYNAMIC SIMULATION IS PARTICULARLY USEFUL ON FLEXIBLE MANUFACTURING LINES SINCE MANY PRODUCT AND PROCESS OPTIONS ARE POSSIBLE.
