Different simulation assignments are available to demonstrate and teach a variety of operations management topics including: Weve made it easy for students to get Littlefield Labs with Operations Management: A Supply Chain Process Approach by Joel D. Wisner all in one convenient package at a student-friendly price. we need to calculate utilization and the nonlinear relationship between utilization and waiting We did not have any analysis or strategy at this point. Demand Forecast- Nave. By getting the bottleneck rate we are able to predict . Thus, at the beginning, we did not take any action till Day 62. *FREE* shipping on qualifying offers. Operations at Littlefield Labs Littlefield Labs uses one kit per blood sample and disposes of the kit after the processing of the sample is completed After matching the sample to a kit, LL then processes the sample on a four step process on three machines as shown in Figure 2. The standard deviation for the period was 3. 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. Furthermore, we thought that buying machines from Station 3 was unnecessary because of the utilization in that station. Anteaus Rezba Start studying LittleField Simulation 1 & 2 Overview. Essay on Littlefield Executive Summary Production Planning and Inventory Control CTPT 310 Littlefield Simulation Executive Report Arlene Myers: 260299905 Rubing Mo: 260367907 Brent Devenne: . 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. When the simulation began, we quickly determined that there were three primary inputs to focus on: the forecast demand curve (job arrivals,) machine utilization, and queue size prior to each station. However, once the initial 50 days data became available, we used forecasting analyses to predict demand and machine capacity. These data are important for forecasting the demand and for deciding on purchasing machines and strategies realized concerning setting up . 0000002058 00000 n November 4th, 2014 The purpose of this simulation was to effectively manage a job shop that assembles digital satellite system receivers. Thus our inventory would often increase to a point between our two calculated optimal purchase quantities. Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. It also never mattered much because we never kept the money necessary to make an efficient purchase until this point. 225 To determine the capacity 9, The few sections of negative correlation formed the basis for our critical learning points. We forecast demand to stay relatively stable throughout the game based on the information provided. 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. | |Station LITTLEFIELD CAPACITY GAME REPORT required for the different contract levels including whether it is financially viable to increase As such, the first decision to be made involved inventory management and raw material ordering. after what period of time does revenue taper off in Simulation 1. The information was used to calculate the forecast demand using the regression analysis. Day | Parameter | Value | It should not discuss the first round. becomes redundant? The game can be quickly learned by both faculty and students. Open Document. I'm spending too much on inventory to truly raise revenue. D: Demand per day (units) Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. We now have a total of five machines at station 1 to clear the bottlenecks and making money quickly. 5.Estimate the best reorder point at peak demand. To get started with the strategies, first, we added some questions for ourselves to make decisions: Littlefield Labs Simulation for Joel D. Wisners Operations Management [Wood, Sam, Kumar, Sunil] on Amazon.com. tudents gain access to this effective learning tool for only $15 more. Faculty can choose between two settings: a high-tech factory named Littlefield Technologies or a blood testing service named Littlefield Labs. And in queuing theory, What might you. Please include your name, contact information, and the name of the title for which you would like more information. The costs of holding inventory at the end were approximately the same as running out of inventory. The demand during the simulation follows a predefined pattern, which is marked by stable low demand, increasing demand, stable high demand and then demand declining sharply. highest utilization, we know thats the bottleneck. Next we calculated what Customer Responsiveness Simulation Write-Up specifically for you for only $16.05 $11/page. At day 50. Bring operations to life with the market-leading operations management simulation used by hundreds of thousands! 4. 6. The traditional trend in heritage management focuses on a conservationist strategy, i.e., keeping heritage in a good condition while avoiding its interaction with other elements. When do we retire a machine as it So the reorder quantity was very less because the lead time was 4 days and with average demand of 13 the inventory in hand would be finished in 2 days which means no production for the next 2 days until . 1. In our final purchase we forgot to account for the inventory we already had when the purchase was made. S: Ordering cost per order ($), and Initially we didnt worry much about inventory purchasing. 89 Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. Littlefield Labs makes it easy for students to see operations management in practice by engaging them in a fun and competitive online simulation of a blood testing lab. PRIOR TO THE GAME See whats new to this edition by selecting the Features tab on this page. 0000004706 00000 n 301 certified . Out of these five options, exponential smoothing with trend displayed the best values of MSE (2.3), MAD (1.17), and MAPE (48%). 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. Operations Policies at Littlefield It is worth mentioning that the EOQ model curve generally has a very flat bottom; and therefore, it is in fairly insensitive to changes in order quantity. To accomplish this we changed the priority at station 2 back to FIFO. Customer demand continues to be random, but the long-run average demand will not change over the product 486-day lifetime. In addition, because the factory is essentially bootstrapping itself financially, management is worried about the possibility of bankruptcy.

Download now Introduction To Forecasting for the Littlefield Simulation BUAD 311: Operations Management fForecasting Objectives Introduce the basic concepts of forecasting and its importance within an organization. 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. We set the purchase for 22,500 units because we often had units left over due to our safe reorder point. Littlefield Simulation Analysis, Littlefield, Initial Strategy, Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01. 2 moving average 10 and 15 day, and also a linear trend for the first 50 days that predicts the 100th day. DAYS 25 Our goal is to function as a reciprocal interdependent team, using each members varied skills and time to complete tasks both well and on time. 257 We tried not to spend our money right away with purchasing new machines since we are earning interest on it and we were not sure what the utilization would be with all three of the machines. You can find answers to most questions you may have about this game in the game description document. From the instruction At s the end of this lifetime, demand will end abruptly and factory operations will be terminated. We changed the batch size back to 3x20 and saw immediate results. After all of our other purchases, utilization capacity and queuing at station 2 were still very manageable. By accepting, you agree to the updated privacy policy. Future demand for forecast was based on the information given.

We calculate the reorder point As shown by the figure above, total revenues generally followed the same trend as demand. It mainly revolved around purchasing machines and inventory to satisfy demand with different level of contracts, maximising the revenue by optimising the utilisation. In gameplay, the demand steadily rises, then steadies and then declines in three even stages. Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. Initially we set the lot size to 3x20, attempting to take advantage of what we had learned from the goal about reducing the lead-time and WIP. Based on the peak demand, estimate the no. By Your forecast may differ based on the forecasting model you use. However, we wrongly attributed our increased lead times to growing demand. Which of the. Which elements of the learning process proved most challenging? How did you forecast future demand? There are two main methods of demand forecasting: 1) Based on Economy and 2) Based on the period. Rank | Team | Cash Balance ($) | S=$1000 LITTLEFIELD TECHNOLOGIES Lastly don't forget to liquidate redundant machines before the simulation ends. tuning 62 | Buy Machine 1 | The revenue dropped and the utilizations of Machine 1 were constantly 1 or near 1 on the previous 5 days. 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.

Daily Demand = 1,260 Kits ROP to satisfy 99% = 5,040 Game 2 Strategy. D=100. Also the queue sizes for station one reach high levels like 169 and above. cost for each test kit in Simulation 1 &2. Using the EOQ model you can determine the optimal order quantity (Q*). For assistance with your order: Please email us at textsales@sagepub.com or connect with your SAGE representative. Background 0 | P a g e We First of all, we purchased a second machine from Station 1; however, we could not think Station 1 would be a bottleneck process. Here are some steps in the process: 1. For questions 1, 2, and 3 assume no parallel processing takes place. Littlefield Simulation game is an important learning tool for understanding operations principles in production environments, and therefore it is widely used by many leading business schools. We also need to calculate the holding cost (H). Round 1 of Littlefield Technologies was quite different from round 2. Available in PDF, EPUB and Kindle. Write a strategy to communicate your brand story through: Each hour of real time represents 1 day in the simulation. Because we didnt want to suffer the cost of purchasing inventory right before the simulation ended we made one final purchase that we thought would last the entire 111 days. 5 PM on February 22 .
