The cost of not receiving inventory in time with a promised lead-time of 0.5 days was way too high. a close to zero on day 360. Littlefield Simulation 2 by Trey Kelley - Prezi Different Littlefield assignments have been designed to teach a variety of traditional operations management topics including: process analysis capacity management forecasting production control inventory control queueing lead time management. The findings of a post-game survey revealed that half or more of the . Thus, we did not know which machine is suitable for us; therefore, we waited 95 days to buy a new machine. maximum cash balance: 265 Thus we adopted a relatively simple method for selecting priority at station 2.

After viewing the queues and the capacity utilization at each station and finding all measures to be relatively low, we decided that we could easily move to contract 3 immediately. The information was used to calculate the forecast demand using the regression analysis. We also looked at, the standard deviation of the number of orders per day. This taught us to monitor the performance of the machines at the times of very high order quantities when considering machine purchases. We would have done this better, because we, had a lot of inventory left over. Before buying machines from two main stations, we were in good position among our competitors. Data was extracted from plot job arrival and analyzed. , Georgia Tech Industrial & Systems Engineering Professor. Furthermore, we thought that buying machines from Station 3 was unnecessary because of the utilization in that station. Get started for FREE Continue.

These data are important for forecasting the demand and for deciding on purchasing machines and strategies realized concerning setting up . 2 Pages. 0000002893 00000 n The game started off by us exploring our factory and ascertaining what were the dos and donts. For the short time when the machine count was the same, stations 1 and 3 could process the inventory at a similar rate. 4 | beaters123 | 895,405 | A linear regression of the day 50 data resulted in the data shown on Table 1 (attached)below. Right before demand stopped growing at day 150, we bought machines at station 3 and station 1 again to account for incoming order growth up until that point in time. I'm spending too much on inventory to truly raise revenue. We didnt consider the cost of paying $1000 a purchase versus the lost interest cost on the payment until demand stabilized after day 150 and we had resolved our problem with batch size and setup times. 03/05/2016 Now we can plug these numbers into the EOQ model to determine the optimal order quantity. 10% minus taxes Forecast of demand: Either enter your demand forecast for the weeks requested below, or use Excel to create a . 1. We calculate the reorder point We used the data in third period to draw down our inventory, because we did not want to be stuck with inventory when, game was over. Based on our success in the last Littlefield Simulation, we tried to utilize the same strategy as last time. 0000001740 00000 n It should not discuss the first round. In particular, we have reversed the previous 50 days of tasks accepted to forecast demand over the next 2- 3 months in the 95% confidence interval. Login . We looked at the first 50 days of raw data and made a linear regression with assumed values. In addition, we will research and tour Darigold Inc. to evaluate their operations, providing analysis and recommended changes where we deem applicable.

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. Renewable and Sustainable Energy Reviews, /, - X-MOL Figure Which station has a bottleneck? Borrowing from the Bank By doing this method, we determined the average demand to date to have been 12. Instant access to millions of ebooks, audiobooks, magazines, podcasts and more. The account includes the decisions we made, the actions we took, and their impact on production and the bottom line. Change the reorder quantity to 3600 kits. 3 | makebigmoney | 1,141,686 | Day 53 Our first decision was to buy a 2nd machine at Station 1. When the simulation first started we made a couple of adjustments and monitored the performance of the factory for the first few days. To ensure we are focused and accomplish these set goals, the following guidelines Running head: Capacity Management In capacity management, www.aladin.co.kr At the end of the final day of the simulation we had 50 units of inventory left over Cash Balance: $ 2,242,693 Days 106-121 Day 268 Day 218-268 Day 209 Focus was to find our EOQ and forecast demand for the remaining days, including the final 50 days where we were not in control.

Avoid ordering too much of a product or raw material, resulting in overstock. Figure 1: Day 1-50 Demand and Linear Regression Model Cunder = $600/order Cover = $1200 (average revenue) - $600 = $600/order, Qnecessary = 111 days * 13 orders/day * 60 units/order = 86,580 units. Littlefield Technologies mainly sells to retailers and small manufacturers using the DSSs in more complex products. According to our regressionanalysis using the first 30 days of demand data, the P-value is less than 0.05, so the variable time has a statistically significant relationship to demand.The demand line equation that we came up with is: Demand = 2.32 + 0.136 * (Day #). 9, We did calculate reorder points throughout the process, but instead of calculating the reorder point as average daily demand multiplied by the 4 days required for shipment we used average daily demand multiplied by 5 days to make sure we always had enough inventory to accommodate orders. Team Pakistan Once you have access to your factory, it is recommended that you familiarize yourself with the simulation game interface, analyze early demand data and plan your strategy for the game. | |Station LITTLEFIELD CAPACITY GAME REPORT Inventory Management 4. gives students hands-on experience as they make decisions in a competitive, dynamic environment.

Led by a push from Saudi Arabia and Russia, OPEC will lower its production ceiling by 2 million B/D from its August quota. When this was the case, station 1 would feed station 2 at a faster rate than station 3. The model requires to, things, the order quantity (RO) and reorder point (ROP). Improving Undergraduate Student Performance on the Littlefield Simulation The first step in the process is investigating the company's condition and identifying where the business is currently positioned in the market. 35.2k views . Using the EOQ model you can determine the optimal order quantity (Q*). To accomplish this we changed the priority at station 2 back to FIFO. 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. 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. Analysis of the First 50 Days We attributed the difference to daily compounding interest but were unsure. Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. should be 690 units and the quantity of 190. At this point we realized that long setup times at both stations were to blame. Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. mL, VarL mD, VarD mDL, VarDL Average & Variance of DL Average & Variance of D Average & Variance of L = Inv - BO (can be positive or negative) Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. Identify several of the more common forecasting methods Measure and assess the errors that exist in all forecasts fManagerial Issues We came very close to stocking out several times, but never actually suffered the losses associated with not being able to fill orders. Forecasting: What It Is, How It's Used in Business and Investing Manage Order Quantities: Station 2 never required another machine throughout the simulation. On For the purpose of this report, we have divided the simulation into seven stages after day 50, explicating the major areas of strategically significant decisions that were made and their resulting B6016 Managing Business Operations 2.
