Reflecting on the simulation exercise, we have made both correct and incorrect decisions. So we purchased a machine at station 2 first. Marcio de Godoy LittleField Simulation 1 & 2 Overview Flashcards | Quizlet The following equation applies to this analysis: Regression Analysis = a + bx After using the first 50 days to determine the demand for the remainder of the Littlefield Simulation Analysis - Term Paper - TermPaper Warehouse 185 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. Thus should have bought earlier, probably around day 52 when utilization rate hit 1. When the simulation first started we made a couple of adjustments and monitored the performance of the factory for the first few days. The account includes the decisions we made, the actions we took, and their impact on production and the bottom line. 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. Littlefield Technologies mainly sells to retailers and small manufacturers using the DSS's in more complex products. Therefore, the optimal order quantity (Q*) is 1721 units. trailer This is the inventory quantity that we purchased and it is the reason we didnt finish the simulation in first. Q* = sqrt(2*100*1000/.0675) = 1721 Your forecast may differ based on the forecasting model you use. Instant access to millions of ebooks, audiobooks, magazines, podcasts and more.

We Does your factory operate under make-to-stock or make-to-order? Faculty can choose between two settings: a high-tech factory named Littlefield Technologies or a blood testing service named Littlefield Labs. When the exercise started, we decided that when the lead time hit 1 day, we would buy one station 1 machine based on our analysis that station 1 takes the longest time which is 0.221 hrs simulation time per batch. You are in: North America We did not intend to buy any machines too early, as we wanted to see the demand fluctuation and the trend first. As day 7 and day 8 have 0 job arrivals, we used day 1-6 figures to calculate the average time for each station to process 1 batch of job arrivals. 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. 153 Background Throughout the game our strategy was to apply the topic leant in Productions and Operation Management Class to balance our overall operations. 113 Should you need additional information or have questions regarding the HEOA information provided for this title, including what is new to this edition, please email sageheoa@sagepub.com.

If the order can be completed on-time, then the faster contract is a good decision. .o. 2, Using the EOQ model you can determine the optimal order quantity (Q*). Initially we set the lot size to 3x20, attempting to take advantage of what we had learned from the goal about reducing the lead-time and WIP. LT managers have decided that, after 268 days of operation, the plant will cease producing the DSS receiver, retool the factory, and sell any remaining inventories. Forecasting Littlefield Laboratories | PDF - Scribd 4 | beaters123 | 895,405 | We looked at the first 50 days of raw data and made a linear regression with assumed values. Initially we didnt worry much about inventory purchasing. 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. Thus, we did not know which machine is suitable for us; therefore, we waited 95 days to buy a new machine. Future demand for forecast was based on the information given. Students learn how to maximize their cash by making operational decisions: buying and selling capacity, adjusting . 7 Pages. In addition, because the factory is essentially bootstrapping itself financially, management is worried about the possibility of bankruptcy. 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.
