We did not have any analysis or strategy at this point. Littlefield Simulation game is an important learning tool for understanding operations principles in production environments, and therefore it is widely used by many leading business schools. We did not intend to buy any machines too early, as we wanted to see the demand fluctuation and the trend first. Except for one night early on in the simulation where we reduced it to contract 2 because we wouldnt be able to monitor the factory for demand spikes, we operated on contract 3 almost the entire time. To calculate the holding cost we need to know the cost per unit and the daily interest rate. As shown by the figure above, total revenues generally followed the same trend as demand. These reports enable factory managers to quickly assess performance and make Littlefield strategy decisions. @littledashboard / littledashboard.tumblr.com. Furthermore, we thought that buying machines from Station 3 was unnecessary because of the utilization in that station. gives students hands-on experience as they make decisions in a competitive, dynamic environment.
