July 2, 2022 littlefield simulation demand forecasting purcell marian class of 1988. We looked at the first 50 days of raw data and made a linear regression with assumed values. By getting the bottleneck rate we are able to predict which of the station may reach full utilization ahead of others and therefore needed more machines to cover the extra load of work to keep the utilization high but not at the peak of 100%. According to Holt's exponential model we forecast the average demand will be 23, by using We never saw a reason to set the priority to step 2 because we never had more machines at station 3 than at station 1. Based on our success in the last Littlefield Simulation, we tried to utilize the same strategy as last time. In early January 2006, Littlefield Technologies (LT) opened its first and only factory to produce its newly developed Digital Satellite System (DSS) receivers. We took the per day sale data that we had and calculated a linear regression. Average Daily Demand = 747 Kits Yearly Demand = 272,655 Kits Holding Cost = $10*10% = $1 EOQ = sqrt(2DS/H) = 23,352 Kits Average Daily Demand = 747 Kits Lead Time = 4 Days ROP = d*L = 2,988 99% of Max. In terms of when to purchase machines, we decided that buying machines as early as possible would be ideal as there was no operating costs after the initial investment in the machine.

Moreover, we also saw that the demand spiked up. Rank | Team | Cash Balance ($) | In a typical setting, students are divided into teams, and compete to maximize their cash position through decisions: buying and selling capacity, adjusting lead time quotes, changing lot sizes and inventory ordering parameters, and selecting scheduling rules. So we purchased a machine at station 2 first. 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. Purchase a second machine for Station 3 as soon as our cash balance reached $137,000 ($100K + 37K). To forecast Demand we used Regression analysis. Analysis of the First 50 Days So the reorder quantity was very less because the lead time was 4 days and with average demand of 13 the inventory in hand would be finished in 2 days which means no production for the next 2 days until . Initially, we tried not to spend much money right away with adding new machines because we were earning interest on cash stock. : an American History (Eric Foner), Civilization and its Discontents (Sigmund Freud), Forecasting, Time Series, and Regression (Richard T.
