After resolving the lead-time issues, we used to switch back the contract to contract-3. (Points: 30) |, The aim of this report is to provide an overview of businesses simulations through TOPSIM, a business management game that establishes a link between business management theory and business management in practice., The production capacity in my first 2 quarters was low but only because it was upcoming, The above table showing the total capacity per hour of each machine center was calculated by taking the number of machines and multiplying them by the run time per piece per minute. 113
Thanks. In the final simulation, we corrected our mistakes. Summary of articles. Littlefield Technologies is an effective teaching tool that the students seem to really enjoy and the students are forced to think logically about the problems that they are facing and they learn from iterative experimentation. 1

Once the priority was changed from FIFO to Step 4, the team noticed that both the utilization at Station 2 and the queues began to exhibit high variance from day to day. 193
Simulation & Gaming. A detailed data analysis and how the game progressed. It is necessary to manage mistakes made in strategy during the game, which can resolve issues down the road to have a successful business plan. Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. | Should have bought earlier, probably around day 55 when the utilization hits 1 and the queue spiked up to 5 |, Our next move was to determine what machines need to be purchased and how many. Customer demand continues to be random, but the long-run average demand will not change over the product 486-day lifetime. Clipping is a handy way to collect important slides you want to go back to later. 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.

Doing this simulation review it will show just how to go about making these changes to save money. Out of these five options, exponential smoothing with trend displayed the best values of MSE (2.3), MAD (1.17), and MAPE (48%). 9. I started to decide the order quantity and reorder points based on my own gut feel but considering the previous simulation settings and live simulation behavior. Overall results and rankings. The winning team is the team with the most cash at the end of the game (cash on hand less debt). 81

Littlefield Initial Strategy When the simulation first started we made a couple of adjustments and monitored the performance of the factory for the first few days. Thereafter we kept an active watch on lead-times and tried to resolve it through the intense team communication and proactive operations-management. Decision 1

This proved to be the most beneficial contract as, long as we made sure that we had the machines necessary to accommodate the, 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. ; and How would you use this in determining your business plan? Group Report 1: Capacity Management The following is an account of our Littlefield Technologies simulation game. Base on the average time taken to process 1 batch of job arrivals, we were able to figure out how Thundercats

We did switch the lot size to 3 by 20 early in the simulation since we know that smaller batch sizes can speed up production. Any remaining machinery or inventory will be useless after Day 268, and thus have no residual value. Management is concerned about this outcome. Create an account to follow your favorite communities and start taking part in conversations. Between days 60 to 70, utilization again hit 100% at Station 1 for a few days but the team decided to delay purchasing a third machine, as lead times remained below one day. However, there will be a 20% increase in demand for the next month of operations as predicted by management, and the production and supply management's problems may come as a problem they can no longer afford. As explained on in chapter 124, we used the following formula: y = a + b*x. This was met by opposition from the Arab population in Palestine and, as violence between the groups increased, the British were forced to turn the region over to the United Nations. On 28 April 1947 a special session of the UN General Assembly established the Special Committee on Palestine (UNSCOP), which had the task of investigating all of the questions surrounding the problems in Palestine and to recommend solutions to be considered by the General Assembly later that year.
Specifically, on day 0, the factory began operations with three stuffers, two testers, and one tuner, and a raw materials inventory of 9600 kits. Summary of articles. . This may have helped us improve our simulation results further. Our revenue per day improved to 200 $/day. 24 hours. In March, April, and May will fire 4, 3, 3, employees respectively. After all of our other purchases, utilization capacity and queuing at station. :
However, we observed, that the option-1 due to curved graph and decreasing inventory consumption would have left us with lesser inventory than the current levels. This helped us do well in our simulations. The decision making for the machines is typically based on the utilization of machines. Borrowing from the Bank
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. This weeks key learning areas have been eye opening and worthwhile. ANSWER : Littlefield 1. Last year our forecast sales were 24,000 when we only sold 19,866; therefore we thought it would be best to leave production at 20,000 bikes. When first approaching this game we met to strategize, forecast, make a meeting schedule, and divide the work. We did intuitive analysis initially and came up the strategy at the beginning of the game. Figure

Littlefield Technologies (LT) has developed another DSS product. We did not change the production quantity. The Israeli-Palestinian conflict has been one of the most important issues that the United Nations has focused on since its founding in 1945. 54 | station 1 machine count | 2 |
We did less messing around with the lot size and priority since these were definitely less important to the overall success of your factory than the number of machines you had. In addition, because the factory is essentially bootstrapping itself financially, management is worried about the possibility of bankruptcy. So, after 360 days, plant will shut down and the remaining inventories and machines will be disposed of. 9
My reasoning for using this strategy is that my products will be extremely useful and beneficial to its consumers; products like BIC and McDonalds are in extreme demand with the situation of todays economy. 100% (5) 100% found this document useful (5 votes) 13K views. However, the difference in choosing between the priorities seemed minimal and is probably only important during times of high demand. Management Strategy
We were asking about each others areas and status. The goal of the symposium is to investigate how research in system dynamics is contributing to simulation-gaming, and how the more general field of simulation-gaming is influencing work in system dynamics. from the word go. Good teamwork is the key. Littlefields management would like to be able to charge the premium prices that customers would be willing to pay for dramatically shorter lead times. Based on initial management analyses, customer demand for this new product is expected to be random, but the average demand will be level over the products 268-day lifetime. Supplemental understanding of the topic including revealing main issues described in the particular theme; One colleague was responsible for customer order management and the other for the capacity management. One solution was that we should let the inventory run out and not reorder anything. In the initial months, demand is expected to grow at a roughly linear rate. We debated whether or not these few exceptions we okay to ignore. This suggested that FIFO was a better strategy for Station 2, so the team switched the priority back at day 75., 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. Despite this, not many teams were aware about what had to be done exactly - which I think hurt their chances. Return On Investment: 549%
We have reinforced many of the concepts and lessons learned in class and had a better understanding of the operation of the Littlefield Technologies facility and how certain modifications would affect the throughput and lead time. In the game, teams are . An implication of this study is that tangible stock-flow tasks are as difficult for humans to control as are purely cognitive tasks. However, observed 100% Utilization at Station #1 with the 17x more queued kits. after how many hours do revenues hit $0 in simulation 1. Ranking

The few sections of negative correlation formed the basis for our critical learning points. A linear regression of the day 50 data resulted in the data shown on Table 1 (attached)below. Littlefield Simulation Solutions and analytical decisons made. Lt Game 2 Strategy. We then determined our best course of action would be to look at our average daily revenue per job (Exhibit 7) and see if we could identify any days when that was less than the maximum of $1,000/job, so we could attempt to investigate what days to check on for other issues. This work reports a laboratory experiment in which managerial performance in dynamic tasks is improved by improving the quality of decisions made in the context of a dynamic environment. Aneel Gautam
We noticed that around day 31, revenues dipped slightly, despite the fact that the simulation was still nowhere near peak demand, suggesting that something was amiss in our process.

after what period of time does revenue taper off in Simulation 1. Later, we were forced to add machines. We were interested in allocating the money towards marketing as opposed to production. But we did not know if it was the reason for the full utilization of the machinery. In addition, Miltons regular supplier had hiked about the prices on the motors that he needed by 25%, while Markowitz had been able to find from a supplier overseas for 25% off temporarily to build customer base. writing your own paper, but remember to 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. The simulation provided five options for cost cutting at the hospital with only two of the options available to select from, in hopes of the best result. These key areas will be discussed throughout the journal to express my understanding of the experience. The decision depends on the expected lead-time, which we promise to the customer. And then we applied the knowledge we learned in the class, did process analysis and modified our strategies according to the performance results dynamically. We wanted our inventory to drop close to zero to minimize overall holding costs, but never actually reach zero. 3. 57
We noticed that the bottleneck was not just at station 1, but at all stations, and that buying a new machine would not be the right choice to make, but rather, changing the way in which the stations processing is queued would be the better option. Forecasting:
Machine stoppage data for the, One of our team members conducted a full operations analysis. Closer to Day 50, shop floor space constraints are limiting the number of jobs being accepted into the factory. By continuing well 17
Fortunately, none of other team were close; otherwise, this shortcoming would have mattered. The goal of our company was to make money, so we needed to upgrade to contract 3 as quickly as possible. (2016, Dec 02). Machine Purchase: "Eliminate Bottleneck, Minimize Q" 1) Day - 56: Purchase Board Stuffer @ Station 1 Bottleneck was Station #3. We also reorder point (kits) and reorder quantity (kits), giving us a value of 49 and 150., 66 | Buy Machine 3 | Both Machine 1 and 3 reached the bottleneck rate as the utilizations at day 62 to day 66 were around 1. 2 | techwizard | 1,312,368 |
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. Pharapreising and interpretation due to major educational standards released by a particular educational institution as well as tailored to your educational institution if different; 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 did not take any corrective measure to increase our profit margins early in the game. 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. Global negotiations to reduce greenhouse gas (GHG) emissions have so far failed to produce an agreement. Eventually, demand should begin to decline at a roughly linear rate. 10000
Do a proactive capacity management : Machines. After some discussion we came to the conclusion that the cost of buying another machine would far outweigh the small loss of revenue of each of these occurrences. As we will see later, this was a slight mistake since the interest rate did have a profound impact on our earnings compared to other groups. Markowicz felt that he had a primary responsibility to the company to ensure that the production process runs smoothly at his plant, and after the first half of 2010, it reported profitable operations and net cash inflows from investing activities was positive for the first time in three years and had already reached $250,000 in just the first half of the year. Click here to review the details. report, Littlefield Technologies Simulation: Batch Sizes Analysis. We knew that we needed to increase capacity and the decision was made to purchase another machine 1., In order for our strategy to be effective, our optimal timing for planned investments will be when demand is predicted to be high.
