Littlefield Game Report Littlefield Technologies is a highly automated company specializing in blood samples testing. The process includes three types of machines and four stages. The four stages involve sample preparing (machine 1), testing (machine 2), centrifuging (machine 3), and additional testing (machine 2). The objective of the game is to maximize the cash on hand by managing the capacity, WIP limit, and the queue discipline. Our team began by analyzing the first 50 days arrival rate data. The demand was predicted to increase at a roughly linear rate for three months. Thus, we used the regression line analysis to estimate the demand for the next 100 days. We found that the demand would follow y=0.076x + 1.11 and we got 12.57 orders for day 150. Next, we decided the number of machines to purchase by comparing capacity of each machine with the capacity required to fulfill the demand. To calculate the capacity of each machine, we used the formula: utilization rate = arrival rate/service rate. Steps to calculate the capacity of each machine: 1) Find the capacity of each day using the utilization rate formula. For machine 2, we double the arrival rate assuming the arriving job went through the testing stage twice on the same day. 2) Average the daily capacity of each machine to get the service rate. Then we found that: Capacity of machine 1 = 8.19 orders/day Capacity of machine 2 = 13.99 orders/day
