Home. capacity to those levels, we will cover the Economic Order Quantity (EOQ) and reorder point Supply Chain Exam 2 (Jacobs 18 - Forecasting) great Going into this game our strategy was to keep track of the utilization for each machine and the customer order queue. At the end of day 350, the factory will shut down and your final cash position will be determined. Sense ells no existirem. By getting the bottleneck rate we are able to predict which of the station may reach full utilization ahead of others and therefore needed more machines to cover the extra load of work to keep the utilization high but not at the peak of 100%. Right before demand stopped growing at day 150, we bought machines at station 3 and station 1 again to account for incoming order growth up until that point in time. Our strategy was to keep track of each machines capacity and the order queue. Part I: How to gather data and what's available. time contracts or long-lead-time contracts?
