H6s k?(. ko"ZE/\hmfaD'>}GV2ule97j|Hm*o]|2U@ O Specifically we were looking for upward trends in job arrivals and queue sizes along with utilizations consistently hitting 100%. In addition, we were placed 17th position in overall team standing. With little time to waste, Team A began by analyzing demand over the first 50 days of operations in order to create a linear regression model to predict demand into the future in order to make critical operational decisions; refer to Figure 1. Some describe it as addictive., Privacy Policy | Terms & Conditions | Return Policy | Site Map We also set up financial calculations in a spreadsheet to compare losses on payment sizes due to the interest lost on the payment during the time until the next purchase was required. 5 We decided to purchase an additional machine for station 1 because it was $10,000 cheaper, utilization was higher here, and this is where all the orders started. Littlefield was developed with Sunil Kumar and Samuel Wood while they were on the faculty of Stanfords Graduate School of Business. We came very close to stocking out several times, but never actually suffered the losses associated with not being able to fill orders. We thought because of our new capacity that we would be able to accommodate this batch size and reduce our lead-time. Thus our inventory would often increase to a point between our two calculated optimal purchase quantities. Challenges The standard performance measure in the Littleeld simulation is each team's ending cash balance relative Play with lot size to maximize profit (Even with lower . Does your factory operate under make-to-stock or make-to-order? As this is a short life-cycle product, managers expect that demand during the 268 day period will grow as customers discover the product, eventually level out, and then decline. At this point, all capacity and remaining inventory will be useless, and thus have no value. The first time our revenues dropped at all, we found that the capacity utilization at station 2 was much higher than at any of the other stations.
