littlefield simulation demand forecasting beau daniel garfunkel. A huge spike in demand caused a very large queue at station 3 and caused our revenues to drop significantly. 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. 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. Future demand for forecast was based on the information given.

Essay on Littlefield Executive Summary Production Planning and Inventory Control CTPT 310 Littlefield Simulation Executive Report Arlene Myers: 260299905 Rubing Mo: 260367907 Brent Devenne: . <]>> 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. 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. At s the end of this lifetime, demand will end abruptly and factory operations will be terminated. I did and I am more than satisfied. Using the cost per kit and the daily interest expense we can calculate the holding cost per unit by multiplying them together. 593 17 (It also helped when we noticed the sentence in bold in the homework description about making sure to account for setup times at each of the stations.) After this, demand was said to be declined at a linear rate (remaining 88 days). This taught us to monitor the performance of the machines at the times of very high order quantities when considering machine purchases. $}D8r DW]Ip7w/\>[100re% startxref However, we wrongly attributed our increased lead times to growing demand. %PDF-1.3 % 7 Pages. Windsor Suites Hotel. With much anticipation we reviewed all the literate that was provided subsequently to assist us in decision making at Littlefield Technologies. To 5 PM on February 22 . The students absolutely love this experience. The platform for the Littlefield simulation game is available through the Littlefield Technologies simulator. Our strategy throughout the stimulation was to balance our work station and reduce the bottleneck. We believe that it was better to overestimate than to. Day | Parameter | Value | Demand forecasts project sales for the next few months or years. Anteaus Rezba Dr. Alexey Rasskazov In two days, we spend a lot of money on kits so we realize we only needed two machines at station 2 and 3. Littlefield Labs Simulation for Ray R.

Moreover, we bought two machines from Station 2 because; it would be better idea to increase our revenue more than Station 1. A huge spike in Capacity Management at Littlefield Labs We did intuitive analysis initially and came up the strategy at the beginning of the game. 89 We will be using variability to The team consulted and decided on the name of the team that would best suit the team. Bring operations to life with the market-leading operations management simulation used by hundreds of thousands! Specifically we were looking for upward trends in job arrivals and queue sizes along with utilizations consistently hitting 100%. Report on Littlefield Technologies Simulation Exercise This proved to be the most beneficial contract as long as we made sure that we had the machines necessary to accommodate the increasing demand through day 150. . Anise Tan Qing Ye Download now 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. Capacity Management at Littlefield Technologies (Exhibit 2: Average time per batch of each station). For most of the time, step 4 was selected as the step to process first. Contract Pricing To get started with the strategies, first, we added some questions for ourselves to make decisions: 0000000016 00000 n 2 key inventory policy decisions that need to be made in simulation 2. We spent money that we made on machines to build capacity quickly, and we spent whatever we had left over on inventory. How much time, Steps to win the Littlefield Blood Lab Simulation, 1. 64 and the safety factor we decided to use was 3. Upon further analysis, we determined the average demand to date to have been 12. REVENUE 0000002058 00000 n Course Hero is not sponsored or endorsed by any college or university. In Littlefield, total operational costs are comprised of raw material costs, ordering costs and holding costs. A report submitted to Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. DAY 1 (8 OCTOBER 3013) llT~0^dw4``r@`rXJX The costs of holding inventory at the end were approximately the same as running out of inventory. Before the simulation started, our team created a trend forecast, using the first 50 days of data, showing us that the bottleneck station was at Station 1. 265 Also the queue sizes for station one reach high levels like 169 and above. 8. 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. 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. Clearing Backlog Orders = 4.367 + 0.397 Putting X = 60, we forecasted the stable demand to be around 35 orders per day. 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. The forecast bucket can be selected at forecast generation time. November 4th, 2014 I know the equations but could use help finding daily demand and figuring it out. We changed the batch size back to 3x20 and saw immediate results. We now have a total of five machines at station 1 to clear the bottlenecks and making money quickly. Have u ever tried external professional writing services like www.HelpWriting.net ? Day 50 . to get full document. We could have used different strategies for the Littlefield Any and all help welcome. 33 Even with random orders here and there, demand followed the trends that were given. We needed to have sufficient capacity to maintain lead times of less than a day and at most, 1 day and 9 hours. This latest move comes only a month after OPEC sig Out of these five options, exponential smoothing with trend displayed the best values of MSE (2.3), MAD (1.17), and MAPE (48%). Management's main concern is managing the capacity of the lab in response to the complex demand pattern predicted. 241 We tried to get our bottleneck rate before the simulation while we only had limited information. This is the inventory quantity that we purchased and it is the reason we didnt finish the simulation in first. Going into this game our strategy was to keep track of the utilization for each machine and the customer order queue. Littlefield Simulation. So we purchased a machine at station 2 first. Autor de l'entrada Per ; Data de l'entrada martin county clerk of court jobs; whats wrong secretary kim dramawiki . 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. And then we applied the knowledge we learned in the . In the capacity management part of the simulation, customer demand is random and student gamers have to use how to forecast orders and build factory capacity around that. The developed queuing approximation method is based on optimal tolling of queues. First of all, we purchased a second machine from Station 1; however, we could not think Station 1 would be a bottleneck process. : Demand Forecast- Nave.

The standard deviation for the period was 3. It appears that you have an ad-blocker running. max revenue for unit in Simulation 1. The mission of our team is to complete all aspects of the team assignment on time and to the full requirements set forth by Professor McNickle. 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. 161 Starting off we could right away see that an additional machine was required at station 2 to handle . 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. Below are our strategies for each sector and how we will input our decisions to gain the Our assumption proved to be true. highest utilization, we know thats the bottleneck. Following, we used regression analysis to forecast demand and machine productivity for the remaining of the simulation. 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. Delays resulting from insufficient capacity undermine LTs promised lead times and ultimately force LT to turn away orders. We also looked at, the standard deviation of the number of orders per day. We used the data in third period to draw down our inventory, because we did not want to be stuck with inventory when, game was over. 25000 Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. Author: Zeeshan-ul-hassan Usmani. 81 Leverage data from your ERP to access analytics and quickly respond to supply chain changes. Station 2 never required another machine throughout the simulation. The information was used to calculate the forecast demand using the regression analysis. Tap here to review the details.

I know the equations but could use help . 1. updated on 20 Therefore, the optimal order quantity (Q*) is 1721 units. Initially, we tried not to spend much money right away with adding new machines because we were earning interest on cash stock. At this point, all capacity and remaining inventory will be useless, and thus have no value. 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. 2. In addition, because the factory is essentially bootstrapping itself financially, management is worried about the possibility of bankruptcy. 17 Littlefield Strategy = Calculating Economic Order Quantity (EOQ) 9 years ago The Economic Order Quantity (EOQ) minimizes the inventory holding costs and ordering costs.

The few sections of negative correlation formed the basis for our critical learning points. Our goal is to function as a reciprocal interdependent team, using each members varied skills and time to complete tasks both well and on time. We also need to calculate the holding cost (H). What might you. 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. FAQs for Littlefield Simulation Game: Please read the game description carefully. We looked at the first 50 days of raw data and made a linear regression with assumed values. The strategy yield Thundercats 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. 2. Manage Order Quantities: 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. 1. 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. allow instructors and students to quickly start the games without any prior experience with online simulations. Managements main concern is managing the capacity of the factory in response to the complex demand pattern. When demand spiked station 3 developed queues if the priority was set to FIFO because station 1 could process the inventory quicker. 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 6. s 1. What are the key insights you have gained from your work with the simulation; 2. 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. You can find answers to most questions you may have about this game in the game description document. 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. Using demand data, forecast (i) total demand on Day 100, and (ii) capacity (machine) requirements for Day 100. tuning Daily Demand = 1,260 Kits ROP to satisfy 99% = 5,040 Game 2 Strategy. You may want to employ multiple types of demand forecasts. 3 orders per day. Using the EOQ model you can determine the optimal order quantity (Q*).

We did not have any analysis or strategy at this point. 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 The only expense we thought of was interest expense, which was only 10% per year. When we reached the end of first period, we looked on game, day 99 and noticed that demand was still growing. 193 3. Initial Strategy Definition In this case, all customers (i.e., those wishing to place. If so, how do we manage or eliminate our bottleneck? 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. This paper presents a systematic literature review of solar energy studies conducted in Nordic built environments to provide an overview of the current status of the research, identify the most common metrics and parameters at high latitudes, and identify research gaps. I. Not a full list of every action, but the June Before purchasing our final two machines, we attempted to drop the batch size from 3x20 to 5x12. The account includes the decisions we made, the actions we took, and their impact on production and the bottom line. 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. Littlefield Technologies (LT) has developed another DSS product. I'm spending too much on inventory to truly raise revenue. 01, 2016 2 likes 34,456 views Education Operations Class: Simulation exercise Kamal Gelya Follow Business Finance, Operations & Strategy Recommended Current & Future State Machining VSM (Value Stream Map) Julian Kalac P.Eng Shortest job first Scheduling (SJF) ritu98 Ahmed Kamal-Littlefield Report Ahmed Kamal b.
