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. Q1: Do we have to forecast demand for the next 168 days given the past 50 days of history? We nearly bought a machine there, but this would have been a mistake.

It also never mattered much because we never kept the money necessary to make an efficient purchase until this point. For example, ordering 1500 units will increase the overall cost, but only by a small amount. Thus we spent $39,000 too much. We needed to have sufficient capacity to maintain lead times of less than a day and at most, 1 day and 9 hours. As we see in an earlier post about predicting demand for the Littlefield Simulation, and its important to remember that the predicted demand and the actual demand will vary greatly.

In addition, we will research and tour Darigold Inc. to evaluate their operations, providing analysis and recommended changes where we deem applicable. The only expense we thought of was interest expense, which was only 10% per year. We have first calculated the bottleneck rate for each station before the simulation started. To set the reorder point and order quantities for the materials we will be choosing between three

Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. 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. The LT factory began production by investing most of its cash into capacity and inventory. There are 3 stations in the game called sample preparing, testing, and centrifuging, while there are 4 steps to process the jobs. We thought because of our new capacity that we would be able to accommodate this batch size and reduce our lead-time. If actual . tuning

Below are our strategies for each sector and how we will input our decisions to gain the In early January 2006, Littlefield Technologies (LT) opened its first and only factory to produce its newly developed Digital Satellite System (DSS) receivers. In addition, the data clearly showedprovided noted that the demand was going to follow an increasing trend for the initial 150 days at least. Return On Investment: 549%
This meant that there were about 111 days left in the simulation. Contact 525 South Center St. Rexburg, ID, 83460 (208) 496-1411 [email protected] Feedback; Follow Facebook Twitter Youtube LinkedIn; Popular . 4816 Comments Please sign inor registerto post comments. 2 Pages.
Subjects. Login . Cunder = $600/order Cover = $1200 (average revenue) - $600 = $600/order, Qnecessary = 111 days * 13 orders/day * 60 units/order = 86,580 units. 1. 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. 0000007971 00000 n

Managements main concern is managing the capacity of the factory in response to the complex demand pattern. 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. Littlefield was developed with Sunil Kumar and Samuel Wood while they were on the faculty of Stanfords Graduate School of Business. . This method relies on the future purchase plans of consumers and their intentions to anticipate demand.
littlefield simulation demand forecasting At the end of day 350, the factory will shut down and your final cash position will be determined. Throughout the game our strategy was to apply the topic leant in Productions and Operation Management Class to balance our overall operations. 25000

We did intuitive analysis initially and came up the strategy at the beginning of the game. Rank | Team | Cash Balance ($) |
Now we can plug these numbers into the EOQ model to determine the optimal order quantity. 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. Figure 1: Day 1-50 Demand and Linear Regression Model
Ahmed Kamal-Littlefield Report Capacity Management At Littlefield Technologies. Initially we set the lot size to 3x20, attempting to take advantage of what we had learned from the goal about reducing the lead-time and WIP.

In addition, because the factory is essentially bootstrapping itself financially, management is worried about the possibility of bankruptcy.
Littlefield Pre-Plan.docx - 1. How to forecast demand? We Analysis of the First 50 Days
Home. 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. Borrowing from the Bank
It was easily identified that major issues existed in the ordering process. The students absolutely love this experience. Thus, at the beginning, we did not take any action till Day 62. The winning team is the team with the most cash at the end of the game (cash on hand less debt). Although the process took a while to completely understand during the initial months of the simulation, the team managed to adjust, learn quickly and finish in 7th place with a cash balance of $1,501,794. prepare for the game, we gathered all the data for the last 50 days and analyzed the data to build We further reduced batch size to 2x30 and witnessed slightly better results. Figure
Going into this game our strategy was to keep track of the utilization for each machine and the customer order queue. 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. SAGE Starting off we could right away see that an additional machine was required at station 2 to handle . 233
Faculty can choose between two settings: a high-tech factory named Littlefield Technologies or a blood testing service named Littlefield Labs.

S: Ordering cost per order ($), and Moreover, we bought two machines from Station 2 because; it would be better idea to increase our revenue more than Station 1. 217
Answer : There are several different ways to do demand forecasting. Strategies for the Little field Simulation Game The next step was to calculate the Economic Order Point (EOP) and Re Order Point (ROP) was also calculated. In addition, we were placed 17th position in overall team standing.

As day 7 and day 8 have 0 job arrivals, we used day 1-6 figures to calculate the average time for each station to process 1 batch of job arrivals. As the demand for orders increases, the reorder According to Holt's exponential model we forecast the average demand will be 23, by using There was no direct, inventory holding cost, however we would not receive money. It also aided me in forecasting demand and calculating the EOQ . average 59%, Station 2 is utilized on average 16% and station 3 is utilized only 7.2% 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. 1 yr. ago.

Littlefield Simulation - YouTube 03/05/2016 When demand stabilized we calculated Qopt with the following parameters: D (annual demand) = 365 days * 12.5 orders/day * 60 units/order = 273,750 units, H (annual holding cost per unit) = $10/unit * 10% interest = $1. a close to zero on day 360. As station 1 has the rate of the process with the 3. Regression Analysis: The regression analysis method for demand forecasting measures the relationship between two variables. How did you forecast future demand? REVENUE
Hence, we wasted our cash and our revenue decreased from $1,000,000 to $120,339, which was a bad result for us. 24 hours. This is a tour to understand the concepts of LittleField simulation game. Using regression analysis a relationship is established between the dependent (quantity demanded) and independent variable (income of the consumer, price of related goods, advertisements, etc. We did not want the revenue to ever drop from $1000, so we took action based on the utilization rates of the machines.
