There are three inputs to the EOQ model: change our reorder point and quantity as customer demand fluctuates? Within the framework of all these, our cash balance was $120,339 at the end of the game, since we could not sell those machines and our result was not quite good as our competitors positions. This book was released on 2005 with total page 480 pages. We looked at the first 50 days of raw data and made a linear regression with assumed values. Pennsylvania State University required for the different contract levels including whether it is financially viable to increase Current State of the System and Your Assignment At s the end of this lifetime, demand will end abruptly and factory operations will be terminated. 7 Pages. This taught us to monitor the performance of the machines at the times of very high order quantities when considering machine purchases. This project attempts to model this game using system dynamics approach, which Littlefield Simulation II. We used the demand forecast to plan machinery and inventory levels. Q1: Do we have to forecast demand for the next 168 days given the past 50 days of history? Moreover, we bought two machines from Station 2 because; it would be better idea to increase our revenue more than Station 1. When we reached the end of first period, we looked on game, day 99 and noticed that demand was still growing. This is the inventory quantity that we purchased and it is the reason we didnt finish the simulation in first. How did you use your demand forecast to determine how many machines to buy? It mainly revolved around purchasing machines and inventory to satisfy demand with different level of contracts, maximising the revenue by optimising the utilisation. Some describe it as addictive., Privacy Policy | Terms & Conditions | Return Policy | Site Map We also need to calculate the holding cost (H).
