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. 2nd stage, we have to reorder quantity (kits) again giving us a value of 70. Littlefield simulation - V.1.docx - LITTLEFIELD SIMULATION 72 hours. 57 | Should have bought earlier, probably around day 55 when the utilization hits 1 and the queue spiked up to 5 | time contracts or long-lead-time contracts? Search consideration: bbl | SPE We did not want the revenue to ever drop from $1000, so we took action based on the utilization rates of the machines. 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. The game started off by us exploring our factory and ascertaining what were the dos and donts. and then took the appropriate steps for the next real day. We took the sales per day data that we had and calculated a liner regression. Course Hero is not sponsored or endorsed by any college or university.

Select: 1 One or more, You are a member of a newly formed team that has been tasked with designing a new product. In addition to this factor, we thought that buying several machines from different stations would decrease our revenue in the following days. 5 | donothing | 588,054 | We tried to get our bottleneck rate before the simulation while we only had limited information. When the simulation first started we made a couple of adjustments and monitored the performance of the factory for the first few days. If priority was set to step 4, station 2 would process the output of station 3 first, and inventory would reach station 3 from station 1 at a slower rate. D=100. Future Students Current Students Employees Parents and Family Alumni. There are 3 stations in the game called sample preparing, testing, and centrifuging, while there are 4 steps to process the jobs. Upon the preliminary meeting with Littlefield management, Team A were presented with all pertinent data from the first 50 days of operations within the facility in order for the firm to analyze and develop an operational strategy to increase Littlefields throughput and ultimately profits.

We, than forecasted that we would have the mean number of, orders plus 1.19 times the standard deviation in the given, day. Demand Prediction 2. In this case, all customers (i.e., those wishing to place. Decisions Made 3. 9 Initial Strategy Choosing the right one depends on your business needs, and the first step is to evaluate each method. Yup, check if you are loosing money (if actual lead time is more than specified in contract) then stop the incoming orders immediately and fulfill the orders in pipeline to minimise the losses. Different forecasting models look at different factors. 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. There are three inputs to the EOQ model: We calculate the reorder point stuffing testing Please discuss whether this is the best strategy given the specific market environment. We now have a total of five machines at station 1 to clear the bottlenecks and making money quickly. Managing Capacity and Lead Time at Littlefield Technologies Team 9s Summary To set the reorder point and order quantities for the materials we will be choosing between three Leena Alex By getting the bottleneck rate we are able to predict which of the . 129 The few sections of negative correlation formed the basis for our critical learning points. : an American History (Eric Foner), Civilization and its Discontents (Sigmund Freud), Forecasting, Time Series, and Regression (Richard T.

Operations Policies at Littlefield Technologies Assignment ). 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. Stage 2 strategy was successful in generating revenue quickly. Although orders arrive randomly to LT, management expects that, on average, demand will follow the trends outlined above. In addition, we were placed 17th position in overall team standing. Topics: Reorder point, Safety stock, Maxima and minima, Inventory. 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. In retrospect, due to lack of sufficient data, we fell short of actual demand by 15 units, which also hurt our further decisions. Before the last reorder, we, should have to calculate the demand for each of the, remaining days and added them together to find the last, We used EOQ model because the game allowed you to place, multiple orders over a period of time. Ending Cash Balance: $1,915,226 (6th Place) This taught us to monitor the performance of the machines at the times of very high order quantities when considering machine purchases. a close to zero on day 360. In addition, this group was extremely competitive they seemed to have a lot of fun competing against one another., Arizona State University business professor, I enjoyed applying the knowledge from class to a real world situation., Since the simulation started on Monday afternoon, the student response has been very positive. Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. 225 DAY 1 (8 OCTOBER 3013) How many machines should we buy or not buy at all?

Plan The next step was to calculate the Economic Order Point (EOP) and Re Order Point (ROP) was also calculated. To minimize this threat, management policy dictates that new equipment cannot be purchased if the remaining cash balance would be insufficient to purchase at least one order quantity worth of raw materials. The cost of not receiving inventory in time with a promised lead-time of 0.5 days was way too high. and Now we can plug these numbers into the EOQ model to determine the optimal order quantity. 4 | beaters123 | 895,405 | @littledashboard / littledashboard.tumblr.com. At this point we realized that long setup times at both stations were to blame. Initial Strategy Definition Next we calculated what Customer Responsiveness Simulation Write-Up specifically for you for only $16.05 $11/page. It also never mattered much because we never kept the money necessary to make an efficient purchase until this point. Students also viewed HW 3 2018 S solutions - Homework assignment Click here to review the details. We found the inventory process rate at stations 1 and 3 to be very similar. Assume a previous forecast, including a trend of 110 units, a previous trend estimate of 10 units, an alpha of .20, and a delta of .30. . When we started to play game, we waited a long time to play game because there are several stations for buying machines and these machines have different processes. How much time, Steps to win the Littlefield Blood Lab Simulation, 1. Anteaus Rezba So we purchased a machine at station 2 first. Students learn how to maximize their cash by making operational decisions: buying and selling capacity, adjusting . November 4th, 2014 When we reached the end of first period, we looked on game, day 99 and noticed that demand was still growing. H: Holding Cost per unit ($),
