DEMAND This is because we had more machines at station 1 than at station 3 for most of the simulation. In retrospect, due to lack of sufficient data, we fell short of actual demand by 15 units, which also hurt our further decisions. I know the equations but could use help finding daily demand and figuring it out. size and to minimize the total cost of inventory. We've updated our privacy policy. Customer demand continues to be random, but the long-run average demand will not change over the product 486-day lifetime. OPERATION MANAGEMENT As demand began to rise we saw that capacity utilization was now highest at station 1. Click here to review the details. As this is a short life-cycle product, managers expect that demand during the 268 day period will grow as customers discover the product, eventually level out, and then decline. 7 Pages. Our final inventory purchase occurred shortly after day 447. Once you have access to your factory, it is recommended that you familiarize yourself with the simulation game interface, analyze early demand data and plan your strategy for the game. In gameplay, the demand steadily rises, then steadies and then declines in three even stages.
