Littlefield Technologies mainly sells to retailers and small manufacturers using the DSSs in more complex products. . Subjects. A summary of the rationale behind the key decisions made would perhaps best explain the results we achieved. where the first part of the most recent simulation run is shown in a table and a graph. The account includes the decisions we made, the actions we took, and their impact on production and the bottom line. We believe that it was better to overestimate than to. 5000 We have first calculated the bottleneck rate for each station before the simulation started. Managing Capacity and Lead Time at Littlefield Technologies Team 9s Summary 3. Littlefield Simulation Kamal Gelya. Figure Initially, we tried not to spend much money right away with adding new machines because we were earning interest on cash stock. 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. The team ascertained our job completion and our Lead Time. In the initial months, demand is expected to grow at a roughly linear rate. As station 1 has the rate of the process with the reorder point and reorder quantity will need to be adjusted accordingly. Summary of actions When the simulation began, we quickly determined that there were three primary inputs to focus on: the forecast demand curve (job arrivals,) machine utilization, and queue size prior to each station. How did you forecast future demand? This method verified the earlier calculation by coming out very close at 22,600 units. should be 690 units and the quantity of 190. The platform for the Littlefield simulation game is available through the Littlefield Technologies simulator. We will be using variability to The first step in the process is investigating the company's condition and identifying where the business is currently positioned in the market. We thought because of our new capacity that we would be able to accommodate this batch size and reduce our lead-time. used to forecast the future demand as the growth of the demand increases at a lower level, increases to a higher level, and then decreases over the course of the project. Based on Economy. Simulation: Simulation forecasting methods imitate the consumer choices that give rise to demand to arrive at a forecast. Our final inventory purchase occurred shortly after day 447. Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. Operations Policies at Littlefield Technologies Assignment We, quickly realized that the restocking cost for inventory was far, higher than the holding cost of inventory. In terms of when to purchase machines, we decided that buying machines as early as possible would be ideal as there was no operating costs after the initial investment in the machine. Bring operations to life with the market-leading operations management simulation used by hundreds of thousands! Any and all help welcome. Survey Methods.

You are in: North America Purchase a second machine for Station 3 as soon as our cash balance reached $137,000 ($100K + 37K). 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. endstream endobj 594 0 obj<>>>/LastModified(D:20040607164655)/MarkInfo<>>> endobj 596 0 obj<>/Font<>/XObject<>/ProcSet[/PDF/Text/ImageC/ImageI]/ExtGState<>/Properties<>>>/StructParents 0>> endobj 597 0 obj<> endobj 598 0 obj[/Indexed 607 0 R 255 608 0 R] endobj 599 0 obj<> endobj 600 0 obj<> endobj 601 0 obj<>/PageElement<>>>>> endobj 602 0 obj<>stream Pennsylvania State University A discussion ensued and we decided to monitor our revenue on this day. Using demand data, forecast (i) total demand on Day 100, and (ii) capacity (machine) requirements for Day 100. We conducted a new estimate every 24 real life hours. H=$0.675 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. Start studying LittleField Simulation 1 & 2 Overview. xb```b````2@( Ranking Based on our success in the last Littlefield Simulation, we tried to utilize the same strategy as last time. How did you use your demand forecast to determine how many machines to buy? Avoid ordering too much of a product or raw material, resulting in overstock. 73 The only expense we thought of was interest expense, which was only 10% per year. We took the per day sale data that we had and calculated a linear regression. You can read the details below. Led by a push from Saudi Arabia and Russia, OPEC will lower its production ceiling by 2 million B/D from its August quota. size and to minimize the total cost of inventory. Avoid ordering an insufficient quantity of product . We used demand forecast to plan purchase of our machinery and inventory levels. We tried to get our bottleneck rate before the simulation while we only had limited information. Although orders arrive randomly to LT, management expects that, on average, demand will follow the trends outlined above. 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. Assignment options include 2-hour games to be played in class and 7-day games to be played outside class. | Actions | Reasons | What should have been done | 2nd stage, we have to reorder quantity (kits) again giving us a value of 70. 153 A huge spike in demand caused a very large queue at station 3 and caused our revenues to drop significantly. 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. We nearly bought a machine there, but this would have been a mistake. 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.
