littlefield simulation demand forecasting

Round 1: 1st Step On the first day we bought a machine at station 1 because we felt that the utilisation rates were too high. Follow me | Winter Simulation Conference The SlideShare family just got bigger. Executive Summary Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. | |Station LITTLEFIELD CAPACITY GAME REPORT Littlefield - Term Paper In the case of Littlefield, let's assume that we have a stable demand (D) of 100 units per day and the cost of placing an order (S) is $1000. Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. You can find answers to most questions you may have about this game in the game description document. While forecast accuracy is rarely 100%, even in the best of circumstances, proven demand forecasting techniques allow supply chain managers to predict future demand with a high degree of accuracy. The few sections of negative correlation formed the basis for our critical learning points. Estimate the future operations of the business. MGT 3900 PLAN REQUIREMENTS FOR MIYAOKA LITTLEFIELD SIMULATION Clemson University MGT 3900 PLAN REQUIREMENTS FOR MIYAOKA LITTLEFIELD SIMULATION Team Name: Questions about the game set up: 1) The cost of a single raw kit is: 2) The lead time to obtain an order of raw kits is: 3) The amount of interest earned on the cash balance is (choose one): a. Course Hero is not sponsored or endorsed by any college or university. Except for one night early on in the simulation where we reduced it to contract 2 because we wouldnt be able to monitor the factory for demand spikes, we operated on contract 3 almost the entire time. Out of these five options, exponential smoothing with trend displayed the best values of MSE (2.3), MAD (1.17), and MAPE (48%). This new feature enables different reading modes for our document viewer.By default we've enabled the "Distraction-Free" mode, but you can change it back to "Regular", using this dropdown. Supply Chain Exam 2 (Jacobs 18 - Forecasting) great where the first part of the most recent simulation run is shown in a table and a graph. Simulation: Simulation forecasting methods imitate the consumer choices that give rise to demand to arrive at a forecast. This quantity minimizes the holding and ordering costs. The next step was to calculate the Economic Order Point (EOP) and Re Order Point (ROP) was also calculated. 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.

Demand forecasting overview - Supply Chain Management | Dynamics 365 It can increase profitability and customer satisfaction and lead to efficiency gains. 0000002816 00000 n ROP. 2. To get started with the strategies, first, we added some questions for ourselves to make decisions: FIRST TIME TO $1 MILLION PAGE 6 LITTLEFIELD SIMULATION - GENERAL WRITE-UP EVALUATION DEMAND FORECASTING AND ESTIMATION We assessed that, demand will be increasing linearly for the first 90 to 110 days, constant till 18o days and then fall of after that. Essay. We took the per day sale data that we had and calculated a linear regression. Borrowing from the Bank As this is a short life-cycle product, managers expect that demand during the 268 day period will grow as customers discover the product, eventually level out, and then decline. 15000 1 Netstock - Best Overall. 2 Pages. Littlefield Simulation Kamal Gelya. The following equation applies to this analysis: Regression Analysis = a + bx After using the first 50 days to determine the demand for the remainder of the The forecasting method used is the rolling average method, which takes previous historical demand and calculates the average for the next forecasting period. In the initial months, demand is expected to grow at a roughly linear rate. If priority was set to step 4, station 2 would process the output of station 3 first, and inventory would reach station 3 from station 1 at a slower rate. Survey methods are the most commonly used methods of forecasting demand in the short run. In terms of choosing a priority Responsiveness at Littlefield Technologies Because we hadnt bought a machine at station 1 we were able to buy the one we really needed at station 3. Open Document. This taught us to monitor the performance of the machines at the times of very high order quantities when considering machine purchases. 2nd stage, we have to reorder quantity (kits) again giving us a value of 70. 20000 Thereafter, calculate the production capacity of each machine. stuffing testing Survey Methods. I'm spending too much on inventory to truly raise revenue. Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. Our assumption proved to be true. Before buying machines from two main stations, we were in good position among our competitors. Executive Summary. D: Demand per day (units) 2. Aneel Gautam We also need to calculate the holding cost (H). 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. Avoid ordering too much of a product or raw material, resulting in overstock. Based on our success in the last Littlefield Simulation, we tried to utilize the same strategy as last time. March 19, 2021 We now have a total of five machines at station 1 to clear the bottlenecks and making money quickly. 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. We expect that there will be 4 different stages of demand that will occur throughout thesimulation, which are: Stage 1: slight increasing in demand from day 1 to day 60 Stage 2: highly increase in demand from day 60 to day 240 Stage 3: demand peaks from day 240 to day 300 Stage 3: sharp decrease in demand from day 300 to day 360. We experienced live examples of forecasting and capacity management as we moved along the game. Specifically we were looking for upward trends in job arrivals and queue sizes along with utilizations consistently hitting 100%. We came very close to stocking out several times, but never actually suffered the losses associated with not being able to fill orders. Which of the following contributed significantly to, Multiple choice questions: Q1- Choose all of the below statementsthat are consistent with lean thinking . Demand is then expected to stabilize. When bundled with the print text, students gain access to this effective learning tool for only $15 more. When we reached the end of first period, we looked on game, day 99 and noticed that demand was still growing. %PDF-1.3 % We tried to get our bottleneck rate before the simulation while we only had limited information. Using demand data, forecast (i) total demand on Day 100, and (ii) capacity (machine) requirements for Day 100. Following, we used regression analysis to forecast demand and machine productivity for the remaining of the simulation.

Windsor Suites Hotel. 3rd stage, while the focus of the first two stages was making the most money, we will now turn our strategy in keeping our lead against other teams. In addition, we will research and tour Darigold Inc. to evaluate their operations, providing analysis and recommended changes where we deem applicable. 2, Best Demand Planning Software for 2023 - Reviews, Pricing 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. Does your factory operate under make-to-stock or make-to-order? DEMAND FORECASTING AND ESTIMATION We assessed that, demand will be increasing linearly for the first 90 to 110 days, constant till 18o days and then fall of after that. reinforces the competitive nature of the game and keeps cash at the forefront of students' minds. Team Contract As demand began to rise we saw that capacity utilization was now highest at station 1. Littlefield Stimulation - Pre-Little Field Paper - StuDocu The forecast bucket can be selected at forecast generation time. Report on Littlefield Technologies Simulation Exercise Capacity Management at Littlefield Technologies change our reorder point and quantity as customer demand fluctuates? Therefore, we took aproactive approach to buying machines and purchased a machine whenever utilization rates rose dangerously high or caused long queues. Littlefield Simulation. Dr. Alexey Rasskazov This meant that there were about 111 days left in the simulation. 3 | makebigmoney | 1,141,686 | Upon the preliminary meeting with Littlefield management, Team A were presented with all pertinent data from the first 50 days of operations within the facility in order for the firm to analyze and develop an operational strategy to increase Littlefields throughput and ultimately profits. Q1: Do we have to forecast demand for the next 168 days given the past 50 days of history? 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. utilization and also calculate EOQ (Economic Order Quantity) to determine the optimal ordering When demand spiked station 3 developed queues if the priority was set to FIFO because station 1 could process the inventory quicker.

Forecasting is the use of historic data to determine the direction of future trends. Moreover, we bought two machines from Station 2 because; it would be better idea to increase our revenue more than Station 1. 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.

Littlefield Simulation 2 strategy - Blogger Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. until day 240. 41 Open Document. Exhibit 1 : OVERALL TEAM STANDING Change the reorder point to 3000 (possibly risking running out of stock). Regression Analysis: The regression analysis method for demand forecasting measures the relationship between two variables. These reports enable factory managers to quickly assess performance and make Littlefield strategy decisions. II. The developed queuing approximation method is based on optimal tolling of queues. Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. 2013 Littlefield Game by Kimee Clegg - Prezi Littlefield Strategy Tools and Advice on How to Wi | Littlefield 35.2k views . Although marketing is confident of the rough shape of demand, there Is not enough marketing data to predict the actual peak demand at this point. 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. 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. Since the cookie sheets can hold exactly 1 dozen cookies, CampXM questions 1. Having more machines seemed like a win-win situation since it does not increase our expenses of running the business, yet decreases our risk of having lead times of over a day. 10000 Also the queue sizes for station one reach high levels like 169 and above. Yellow and gray lines represent maximum and minimum variability based on two standard deviations (95%). The team ascertained our job completion and our Lead Time. a close to zero on day 360. Assume a previous forecast, including a trend of 110 units, a previous trend estimate of 10 units, an alpha of .20, and a delta of .30. 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. This is the inventory quantity that we purchased and it is the reason we didnt finish the simulation in first. Based on the linear decrease in revenue after a lead time of one day, it takes 9 hours for the revenue to drop to $600 and our profits to be $0. As explained on in chapter 124, we used the following formula: y = a + b*x.
