O Littlefield Simulation Project Analysis. By getting the bottleneck rate we are able to predict which of the station may reach full utilization ahead of others and therefore needed more machines to cover the extra load of work to keep the utilization high but not at the peak of 100%. This taught us to monitor the performance of the machines at the times of very high order quantities when considering machine purchases. Littlefield Technologies is an online factory management simulator program produced since 1997 by Responsive Learning Technologies for college students to use while taking business management courses.

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. Once the initial first 50 days of data became available, we plotted the data against different forecasting methods: Moving average, weighted moving average, exponential smoothing, exponential smoothing with trend, and exponential smoothing with trend and season. ,&"aU"de f QBRg0aIq@8d):oItFMXtAQ|OVvJXar#$G *m J: (6uxgN.,60I/d%`h`T@& X(TBeAn There are two main methods of demand forecasting: 1) Based on Economy and 2) Based on the period. 9,
Which elements of the learning process proved most challenging? 1. As we see in an earlier post about predicting demand for the Littlefield Simulation, and its important to remember that the predicted demand and the actual demand will vary greatly. Out of these five options, exponential smoothing with trend displayed the best values of MSE (2.3), MAD (1.17), and MAPE (48%). Our primary goal for the Little field Simulation game is to meet the demand and supply. There is a total of three methods of demand forecasting based on the economy: Macro-level Forecasting: It generally deals with the economic environment which is related to the economy as calculated by the Index of Industrial . 6 | mas001 | 472,296 |

The simple EOQ model below only applies to periods of constant demand. 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. 3 orders per day. 1. The developed queuing approximation method is based on optimal tolling of queues. 8. change our reorder point and quantity as customer demand fluctuates? Plugging in the numbers $2500*.00027=.675, we see that the daily holding cost per unit (H) is $0.675. It also aided me in forecasting demand and calculating the EOQ . 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. Let's assume that the cost per kit is $2500; that the yearly interest expense is 10%; andy therefore that the daily interest expense is .027%. The new product is manufactured using the same process as the product in the assignment Capacity Management at Littlefield Technologies neither the process sequence nor the process time distributions at each tool have changed. 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. 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. Demand forecasting has the answers.
