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. Different forecasting models look at different factors. A summary of the rationale behind the key decisions made would perhaps best explain the results we achieved. After we purchased machines from Station 1 and Station 2, our revenue and cash balance started to decrease due to the variable costs of buying kits. We attributed the difference to daily compounding interest but were unsure. Rank | Team | Cash Balance ($) | Course Hero is not sponsored or endorsed by any college or university. This meant that there were about 111 days left in the simulation. Therefore, the optimal order quantity (Q*) is 1721 units. It was easily identified that major issues existed in the ordering process.

Which station has a bottleneck? 153 This condition results in the link between heritage and tourism to be established as juxtaposed process, which gives rise to the need to broaden the concept of heritage and how it can be used through tourism to . Initial Strategy 1st stage, we knew there will be bottleneck at station 1 and 3 so additional machines must be purchased. Littlefield Simulation #1 Write Up Team: CocoaHuff Members: Nick Freeth, Emanuel Martinez, Sean Hannan, Hsiang-yun Yang, Peihsin Liao f1. If so, Should we focus on short lead- We've encountered a problem, please try again. When the simulation first started we made a couple of adjustments and monitored the performance of the factory for the first few days. We never saw a reason to set the priority to step 2 because we never had more machines at station 3 than at station 1.

Our final inventory purchase occurred shortly after day 447. xb```b````2@( The information was used to calculate the forecast demand using the regression analysis. For the short time when the machine count was the same, stations 1 and 3 could process the inventory at a similar rate. 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. However, once the initial 50 days data became available, we used forecasting analyses to predict demand and machine capacity. given to us, we know that we will see slight inflection around day 60 and it will continue to grow When bundled with the print text, students gain access to this effective learning tool for only $15 more. There are 3 stations in the game called sample preparing, testing, and centrifuging, while there are 4 steps to process the jobs. Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. Unfortunately not, but my only advice is that if you don't know what you're doing, do as little as possible so at least you will stay relatively in the middle However, we wrongly attributed our increased lead times to growing demand. So the reorder quantity was very less because the lead time was 4 days and with average demand of 13 the inventory in hand would be finished in 2 days which means no production for the next 2 days until . In addition, because the factory is essentially bootstrapping itself financially, management is worried about the possibility of bankruptcy. Base on the average time taken to process 1 batch of job arrivals, we were able to figure out how ev We are making money now at station 2 and station 3. How many machines should we buy or not buy at all? We, quickly realized that the restocking cost for inventory was far, higher than the holding cost of inventory. There was no direct, inventory holding cost, however we would not receive money. Open Document. Calculate the inventory holding cost, in dollars per unit per year. Looking at our Littlefield Simulation machine utilization information from the first 50 days, it was fairly easy to recognize the initial machine bottleneck. We now have a total of five machines at station 1 to clear the bottlenecks and making money quickly. To determine the capacity Survey Methods. Free access to premium services like Tuneln, Mubi and more. 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. The findings of a post-game survey revealed that half or more of the .

Forecasting is the use of historic data to determine the direction of future trends. Different Littlefield assignments have been designed to teach a variety of traditional operations management topics including: Assignment options include 2-hour games to be played in class and 7-day games to be played outside class. Decision topics include demand forecasting, location, lot sizing, reorder point, and capacity planning, among others. capacity is costly in general, we want to utilize our station highly. change our reorder point and quantity as customer demand fluctuates? You may want to employ multiple types of demand forecasts. 2. 1. We bought more reorder point (kits) and sold it for Strategy description We took the sales per day data that we had and calculated a liner regression.

FAQs for Littlefield Simulation Game: Please read the game description carefully. Use forecasting to get linear trend regression and smoothing models. In addition, we were placed 17th position in overall team standing. 2455 Teller Road We did not have any analysis or strategy at this point. 0000004484 00000 n We forecast demand to stay relatively stable throughout the game based on the information provided. Clearing Backlog Orders = 4.367 + 0.397 Putting X = 60, we forecasted the stable demand to be around 35 orders per day. 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.

We calculate the reorder point required for the different contract levels including whether it is financially viable to increase The account includes the decisions we made, the actions we took, and their impact on production and the bottom line. Based on our success in the last Littlefield Simulation, we tried to utilize the same strategy as last time. The few sections of negative correlation formed the basis for our critical learning points. . 2. | Actions | Reasons | What should have been done | However, this in fact hurt us because of long setup times at station 1 and 3. 265 20 I know the equations but could use help . V8. OB Deliverable. 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. Initially, we tried not to spend much money right away with adding new machines because we were earning interest on cash stock. 3. 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.
