The objective was to maximize cash at the end of the product life-cycle (270 days) by optimizing the process design. We took the sales per day data that we had and calculated a liner regression. The first step in the process is investigating the company's condition and identifying where the business is currently positioned in the market. In the LittleField Game 2, our team had to plan how to manage the capacity, scheduling, purchasing, and contract quotations to maximize the cash generated by the lab over its lifetime. Decisions Made Contract Pricing 2, last month's forecast + (actual demand - last month's demand) an additional parameter used in an exponential smoothing equation that includes an adjustment for trend. Next we, calculated what game it would be in 24 hours, and then we, plugged that into the linear regression to get the mean, forecasted number of orders on that day. A huge spike in demand caused a very large queue at station 3 and caused our revenues to drop significantly. until day 240. This proved to be the most beneficial contract as long as we made sure that we had the machines necessary to accommodate the increasing demand through day 150. The students absolutely love this experience. Round 1: 1st Step On the first day we bought a machine at station 1 because we felt that the utilisation rates were too high. I know the equations but could use help finding daily demand and figuring it out. You can find answers to most questions you may have about this game in the game description document. 41 Although marketing is confident of the rough shape of demand, there Is not enough marketing data to predict the actual peak demand at this point.
