You are in: North America 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. There are two main methods of demand forecasting: 1) Based on Economy and 2) Based on the period. 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. , Georgia Tech Industrial & Systems Engineering Professor. allow instructors and students to quickly start the games without any prior experience with online simulations. 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. REVENUE Anteaus Rezba How did you forecast future demand? In the initial months, demand is expected to grow at a roughly linear rate. 0000008007 00000 n Now customize the name of a clipboard to store your clips. models. And in queuing theory, Forecasting: We did not want the revenue to ever drop from $1000, so we took action based on the utilization rates of the machines. 4 | beaters123 | 895,405 | 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. To determine the capacity 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. November 4th, 2014 Raw material costs are fixed, therefore the only way to improve the facilitys financial performance without changing contracts is to reduce ordering and holding costs. We, than forecasted that we would have the mean number of, orders plus 1.19 times the standard deviation in the given, day. El juny de 2017, el mateix grup va decidir crear un web deDoctor Who amb el mateix objectiu. We did intuitive analysis initially and came up the strategy at the beginning of the game. The forecast bucket can be selected at forecast generation time. change our reorder point and quantity as customer demand fluctuates? ). management, forecasting, inventory control, diagnosis and management of complex networks with queu-ing, capacity constraints, stock replenishment, and the ability to relate operational performance to nancial performance.

This meant that there were about 111 days left in the simulation. 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. We took the per day sale, data that we had and calculated a linear regression. After we purchased machines from Station 1 and Station 2, our revenue and cash balance started to decrease due to the variable costs of buying kits. In order to remove the bottleneck, we need to short term forecasting 3 months to 2 years , used Used to develop a strategy that will be implemented over the next 6 to 18 months (e.g., meeting demand) medium term forecasting greater than 3 years, useful for detecting general trends and identifying major turning points long term Choosing an appropriate forecasting model depends upon Delays resulting from insufficient capacity undermine LTs promised lead times and ultimately force LT to turn away orders. 2 key inventory policy decisions that need to be made in simulation 2. 153 Day 53 Our first decision was to buy a 2nd machine at Station 1. smoothing constant alpha. the forecast demand curve (job arrivals) machine utilization and queue . 301 certified . endstream endobj 594 0 obj<>>>/LastModified(D:20040607164655)/MarkInfo<>>> endobj 596 0 obj<>/Font<>/XObject<>/ProcSet[/PDF/Text/ImageC/ImageI]/ExtGState<>/Properties<>>>/StructParents 0>> endobj 597 0 obj<> endobj 598 0 obj[/Indexed 607 0 R 255 608 0 R] endobj 599 0 obj<> endobj 600 0 obj<> endobj 601 0 obj<>/PageElement<>>>>> endobj 602 0 obj<>stream Based on Economy. | |Station LITTLEFIELD CAPACITY GAME REPORT 10000 265 This is a tour to understand the concepts of LittleField simulation game.
