In the initial months, demand is expected to grow at a roughly linear rate. 0000001740 00000 n 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. %%EOF We In two days, we spend a lot of money on kits so we realize we only needed two machines at station 2 and 3. In a typical setting, students are divided into teams, and compete to maximize their cash position through decisions: buying and selling capacity, adjusting lead time quotes, changing lot sizes and inventory ordering parameters, and selecting scheduling rules. 2013 Overview Can gather data on almost every aspect of the game - Customer orders We tried to get our bottleneck rate before the simulation while we only had limited information. Ending Cash Balance: $1,915,226 (6th Place) Starting off we could right away see that an additional machine was required at station 2 to handle . This lasted us through the whole simulation with only a slight dip in revenue during maximum demand. On 15000 We decided to purchase an additional machine for station 1 because it was $10,000 cheaper, utilization was higher here, and this is where all the orders started. 0000005301 00000 n @littledashboard / littledashboard.tumblr.com. Our primary goal for the Little field Simulation game is to meet the demand and supply. PRIOR TO THE GAME It appears that you have an ad-blocker running. Manage Order Quantities: 3. As the demand for orders decreases, the 2. Littlefield Technologies Factory Simulation: . The strategy yield Thundercats Total All rights reserved. Littlefield Simulation Kamal Gelya. change our reorder point and quantity as customer demand fluctuates? We have first calculated the bottleneck rate for each station before the simulation started. Customer demand continues to be random, but the long-run average demand will not change over the product 486-day lifetime. This quantity minimizes the holding and ordering costs. 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. Forecasting is the use of historic data to determine the direction of future trends. https://www.coursehero.com/file/19806772/Barilla-case-upload-coursehero/ Q1. The available values are: Day, Week, and Month. As day 7 and day 8 have 0 job arrivals, we used day 1-6 figures to calculate the average time for each station to process 1 batch of job arrivals. We tried to get our bottleneck rate before the simulation while we only had limited information.

From the instruction Below are our strategies for each sector and how we will input our decisions to gain the We than, estimated that demand would continue to increase to day, 105. Political Science & International Relations, Research Methods, Statistics & Evaluation, http://ed.gov/policy/highered/leg/hea08/index.html, CCPA Do Not Sell My Personal Information. Tap here to review the details. 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. Our goals were to minimize lead time by reducing the amount of jobs in queue and ensuring that we had enough machines at each station to handle the capacity. There are two main methods of demand forecasting: 1) Based on Economy and 2) Based on the period. 8 August 2016. 73 the result of the forecast we average the result of forecasting.

Processing in Batches 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. Thus, in this method, an organization conducts surveys with consumers to determine the demand for their existing products and services and anticipate the future demand accordingly. Station 2 never required another machine throughout the simulation. Using simulation, a firm can combine time-series and causal methods to answer such questions as: What will be the impact of a price pro motion? 1st stage, we knew there will be bottleneck at station 1 and 3 so additional machines must be purchased. Tips for playing round 1 of the Littlefield Technologies simulation. 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. 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. We analyzed in Excel and created a dashboard that illustrates different data. Regression Analysis: The regression analysis method for demand forecasting measures the relationship between two variables. The few sections of negative correlation formed the basis for our critical learning points. How did you forecast future demand? Which elements of the learning process proved most challenging? Thus we adopted a relatively simple method for selecting priority at station 2. Estimate the future operations of the business. Pennsylvania State University 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%. Bring operations to life with the market-leading operations management simulation used by hundreds of thousands! 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. 4816 Comments Please sign inor registerto post comments. 0000002541 00000 n Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. 1 We, than forecasted that we would have the mean number of, orders plus 1.19 times the standard deviation in the given, day. Within the framework of all these, our cash balance was $120,339 at the end of the game, since we could not sell those machines and our result was not quite good as our competitors positions.
