Starting at 5 PM on Wednesday, February 27, the simulation will begin The game will end at 9 PM on Sunday, March 3. Future demand for forecast was based on the information given. 1 CHE101 - Summary Chemistry: The Central Science, Dr. Yost - Exam 1 Lecture Notes - Chapter 18, 1.1 Functions and Continuity full solutions. trailer If the order can be completed on-time, then the faster contract is a good decision. I know the equations but could use help . We started the game with no real plan in mind unlike round 2 where we formulated multiple strategies throughout the duration of the game. Section 81 Avoid ordering too much of a product or raw material, resulting in overstock. Led by a push from Saudi Arabia and Russia, OPEC will lower its production ceiling by 2 million B/D from its August quota. Why? 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. . The platform for the Littlefield simulation game is available through the Littlefield Technologies simulator. Get started for FREE Continue. How did you forecast future demand? a close to zero on day 360. 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. The team consulted and decided on the name of the team that would best suit the team. We then set the reorder quantity and reorder point to 0. 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. Question 1 Demand Forecasting We were told that demand would be linearly increasing for the first 90-110 days, constant till day 180 and then fall off after that. size and to minimize the total cost of inventory. . July 2, 2022 littlefield simulation demand forecasting purcell marian class of 1988. Use forecasting to get linear trend regression and smoothing models. Students learn how to maximize their cash by making operational decisions: buying and selling capacity, adjusting lead time quotes, changing inventory ordering parameters, and selecting scheduling rules. Borrowing from the Bank The average queues at stations 1 and 3 were reduced.

Start studying LittleField Simulation 1 & 2 Overview. Littlefield Technologies is a factory simulator that allows students to compete . Before the game started, we tried to familiarize with the process of the laboratories and calculating the costs (both fixed and variable costs) based on the information on the sheet given. Current State of the System and Your Assignment until day 240. the components on PC boards and soldering them at the board stuffing station . We did intuitive analysis initially and came up the strategy at the beginning of the game. The team ascertained our job completion and our Lead Time. Identify several of the more common forecasting methods Measure and assess the errors that exist in all forecasts fManagerial Issues Nik Wolford, Dan Moffet, Viktoryia Yahorava, Alexa Leavitt. 241 Team We experienced live examples of forecasting and capacity management as we moved along the game. . the formula given, with one machines on each station, and the average expected utilization rate, we have gotten the answer that the And the station with the fastest process rate is station two. Calculate the inventory holding cost, in dollars per unit per year. Our goals were to minimize lead time by . Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. DEMAND 1 You can find answers to most questions you may have about this game in the game description document. Littlefield Technologies charges a premium and competes by promising to ship a receiver within 24 hours of receiving the order, or the customer will receive a rebate based on the delay. Since the cookie sheets can hold exactly 1 dozen cookies, CampXM questions 1. However, this in fact hurt us because of long setup times at station 1 and 3. Management is currently quoting 7-day lead times, but management would like to charge the higher prices that customers would pay for dramatically shorter lead times. What might you. This will give you a more well-rounded picture of your future sales View the full answer Tags. 9 The following is an account of our Littlefield Technologies simulation game. Explanations. This quantity minimizes the holding and ordering costs. Clearing Backlog Orders = 4.367 + 0.397 Putting X = 60, we forecasted the stable demand to be around 35 orders per day. time. Since the Littlefield Lab simulation game is a team game on the internet, played for the first time at an English-speaking university in Vietnam, it is . A variety of traditional operations management topics were discussed and analyzed during the simulation, including demand forecasting, queuing . None of the team's members have worked together previously and thus confidence is low. 0000003038 00000 n Webster University Thailand. After we gathered the utilization data for all three stations, we know that Station 1 is utilized on We didnt consider the cost of paying $1000 a purchase versus the lost interest cost on the payment until demand stabilized after day 150 and we had resolved our problem with batch size and setup times. We, than forecasted that we would have the mean number of, orders plus 1.19 times the standard deviation in the given, day. At s the end of this lifetime, demand will end abruptly and factory operations will be terminated. prepare for the game, we gathered all the data for the last 50 days and analyzed the data to build Demand forecasts project sales for the next few months or years. We attributed the difference to daily compounding interest but were unsure. 749 Words. 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. 1st stage, we knew there will be bottleneck at station 1 and 3 so additional machines must be purchased. Therefore, the optimal order quantity (Q*) is 1721 units. 15 ( EOQ / (Q,r) policy: Suppose you are playing the Littlefield Game and you forecast that the daily demand rate stabilizes after day 120 at a mean value of 11 units per day with a standard deviation of 3.5 units per day. We did not intend to buy any machines too early, as we wanted to see the demand fluctuation and the trend first. 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. 0000004484 00000 n As demand began to rise we saw that capacity utilization was now highest at station 1. We thought because of our new capacity that we would be able to accommodate this batch size and reduce our lead-time. We tried to get our bottleneck rate before the simulation while we only had limited information. 3. Before buying machines from two main stations, we were in good position among our competitors. Hence, we wasted our cash and our revenue decreased from $1,000,000 to $120,339, which was a bad result for us. Customer demand continues to be random, but the long-run average demand will not change over the product 486-day lifetime. Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. Station Utilization: Purchasing Supplies Report on Littlefield Technologies Simulation Exercise The objective was to maximize cash at the end of the product life-cycle (270 days) by optimizing the process design. Moreover, we bought two machines from Station 2 because; it would be better idea to increase our revenue more than Station 1. However, we wrongly attributed our increased lead times to growing demand. Delays resulting from insufficient capacity undermine LTs promised lead times and ultimately force LT to turn away orders. For the purpose of this report, we have divided the simulation into seven stages after day 50, explicating the major areas of strategically significant decisions that were made and their resulting B6016 Managing Business Operations When bundled with the print text, students gain access to this effective learning tool for only $15 more. 265 Our final inventory purchase occurred shortly after day 447. Initially we didnt worry much about inventory purchasing. updated on 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. We did intuitive analysis initially and came up the strategy at the beginning of the game. Summary of actions )XbXYHX*:T;PQ G8%+dQ1bQpRag2a c E8y&0*@R` - 4e:``?y}g p W These data are important for forecasting the demand and for deciding on purchasing machines and strategies realized concerning setting up . 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. change our reorder point and quantity as customer demand fluctuates? Als nostres webs oferimOne Piece,Doctor Who,Torchwood, El Detectiu ConaniSlam Dunkdoblats en catal. Annual Demand: 4,803 kits Safety stock: 15 kits Order quanity: 404 kits Reorder point: 55 kits We decided that the reorder point should be changed to 70 kits to avoid running out of inventory in the event that demand rapidly rose. 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. 0000000649 00000 n SOMETIMES THEY TAKE A FEW MINUTES TO BE PROCESSED. Which of the. In addition, because the factory is essentially bootstrapping itself financially, management is worried about the possibility of bankruptcy. Estimate peak demand possible during the simulation (some trend will be given in the case). 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. customer contracts that offer different levels of lead times and prices.

Littlefield Technologies Factory Simulation: . It offers the core functionality of a demand forecasting solution and is designed so that it can easily be extended. Project 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. We also changed the priority of station 2 from FIFO to step 4. 2455 Teller Road 177 For the short time when the machine count was the same, stations 1 and 3 could process the inventory at a similar rate. 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. Capacity Planning 3. Thus we wanted the inventory from station 1 to reach station 3 at a rate to effectively utilize all of the capability of the machines. 105 0000001740 00000 n The LT factory began production by investing most of its cash into capacity and inventory. Return On Investment: 549% Which of the following contributed significantly to, Multiple choice questions: Q1- Choose all of the below statementsthat are consistent with lean thinking . If actual . When the simulation first started we made a couple of adjustments and monitored the performance of the factory for the first few days. The model requires to, things, the order quantity (RO) and reorder point (ROP). After all of our other purchases, utilization capacity and queuing at station 2 were still very manageable. OPERATION MANAGEMENT Furthermore, we thought that buying machines from Station 3 was unnecessary because of the utilization in that station. This meant that there were about 111 days left in the simulation. - A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 1a2c2a-ZDc1Z . 41 %%EOF ](?='::-SZx$sFGOZ12HQjjmh sT!\,j\MWmLM).k" ,qh,6|g#k#>*88Z$B \'POXbOI!PblgV3Bq?1gxfZ)5?Ws}G~2JMk c:a:MSth. Going into this game our strategy was to keep track of the utilization for each machine and the customer order queue. In addition, we were placed 17th position in overall team standing. time contracts or long-lead-time contracts? 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. The collective opinion method of data forecasting leverages the knowledge and experience of . From the instruction 3 | makebigmoney | 1,141,686 | Change the reorder quantity to 3600 kits.

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. The developed queuing approximation method is based on optimal tolling of queues. In two days, we spend a lot of money on kits so we realize we only needed two machines at station 2 and 3. So we purchased a machine at station 2 first. We forecast demand to stay relatively stable throughout the game based on the information provided. Mission 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. 0000008007 00000 n 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. 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. 0000002058 00000 n We did intuitive analysis initially and came up the strategy at the beginning of the game. We've updated our privacy policy.

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. We looked at the first 50 days of raw data and made a linear regression with assumed values. It can increase profitability and customer satisfaction and lead to efficiency gains. In particular, we have reversed the previous 50 days of tasks accepted to forecast demand over the next 2- 3 months in the 95% confidence interval. How did you use your demand forecast to determine how many machines to buy? Written Assignment: Analysis of Game 2 of Littlefield Technologies Simulation Due March 14, 8:30 am in eDropbox Your group is going to be evaluated in part on your success in the game and in part on how clear, well structured and thorough your write-up is. There are three inputs to the EOQ model: Faculty can choose between two settings: a high-tech factory named Littlefield Technologies or a blood testing service named Littlefield Labs. 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. 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. We bought more reorder point (kits) and sold it for Strategy description
