We did not intend to buy any machines too early, as we wanted to see the demand fluctuation and the trend first. Starting off we could right away see that an additional machine was required at station 2 to handle . 86% certainty). After making enough money, we bought another machine at station 1 to accommodate the growing demand average by reducing lead-time average and stabilizing our revenue average closer to the contract agreement mark of $1250. 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. So we purchased a machine at station 2 first. Collective Opinion. When we started to play game, we waited a long time to play game because there are several stations for buying machines and these machines have different processes. 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.
