As shown by the figure above, total revenues generally followed the same trend as demand. We did intuitive analysis initially and came up the strategy at the beginning of the game. Littlefield Simulation. llT~0^dw4``r@`rXJX Calculate the inventory holding cost, in dollars per unit per year. It will depend on how fast demand starts growing after day 60. We believe that it was better to overestimate than to. We now have a total of five machines at station 1 to clear the bottlenecks and making money quickly. When bundled with the print text, students gain access to this effective learning tool for only $15 more. Executive Summary. Login . Avoid ordering an insufficient quantity of product . There are three inputs to the EOQ model: mL, VarL mD, VarD mDL, VarDL Average & Variance of DL Average & Variance of D Average & Variance of L = Inv - BO (can be positive or negative) Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. Machine configuration:
Has anyone done the Littlefield simulation? $600. We came very close to stocking out several times, but never actually suffered the losses associated with not being able to fill orders. This is the inventory quantity that we purchased and it is the reason we didnt finish the simulation in first. Demand

Looks like youve clipped this slide to already. In gameplay, the demand steadily rises, then steadies and then declines in three even stages. Demand rate (orders / day) 0 Day 120 Day 194 Day 201. In addition, we were placed 17th position in overall team standing. At s the end of this lifetime, demand will end abruptly and factory operations will be terminated. 9,
After this, demand was said to be declined at a linear rate (remaining 88 days). $400 profit. 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 Figure 1: Day 1-50 Demand and Linear Regression Model

If so, when do we adjust or When and what is the reorder point and order quantity? We forecast demand to stay relatively stable throughout the game based on . Essentially, what we're trying to do with the forecast is: 1. 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. We nearly bought a machine there, but this would have been a mistake. And then we applied the knowledge we learned in the . For example, ordering 1500 units will increase the overall cost, but only by a small amount. 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. Team Pakistan Based on Economy.
At the end of day 350, the factory will shut down and your final cash position will be determined. Our strategy throughout the stimulation was to balance our work station and reduce the bottleneck.

We would have done this better, because we, had a lot of inventory left over. 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. We took the per day sale, data that we had and calculated a linear regression. Enjoy access to millions of ebooks, audiobooks, magazines, and more from Scribd. Littlefield Simulation Report: Team A
Next we, calculated what game it would be in 24 hours, and then we, plugged that into the linear regression to get the mean, forecasted number of orders on that day. where the first part of the most recent simulation run is shown in a table and a graph. time contracts or long-lead-time contracts? Simulation: Simulation forecasting methods imitate the consumer choices that give rise to demand to arrive at a forecast. What will be the impact of a competitor opening a store nearby? Why? 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.

The team ascertained our job completion and our Lead Time. we need to calculate utilization and the nonlinear relationship between utilization and waiting
We further reduced batch size to 2x30 and witnessed slightly better results. We have first calculated the bottleneck rate for each station before the simulation started. That will give you a well-rounded picture of potential opportunities and pitfalls. 5 | donothing | 588,054 |
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. 233

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. To calculate the holding cost we need to know the cost per unit and the daily interest rate.
8. Mission The cost of not receiving inventory in time with a promised lead-time of 0.5 days was way too high. West University Blvd., Melbourne, FL . Specifically, on day 0, the factory began operations with three stuffers, two testers, and one tuner, and a raw materials inventory of 9600 kits. To a close to zero on day 360.

In early January 2006, Littlefield Technologies (LT) opened its first and only factory to produce its newly developed Digital Satellite System (DSS) receivers. We did not have any analysis or strategy at this point. Purchasing Supplies
When this didnt improve lead-time at the level we expected we realized that the increased lead-time was our fault. Purchase a second machine for Station 3 as soon as our cash balance reached $137,000 ($100K + 37K). It will depend on how fast demand starts growing after day 60. the operation.

In the LittleField Game 2, our team had to plan how to manage the capacity, scheduling, purchasing, and contract quotations to maximize the cash generated by the lab over its lifetime. management, forecasting, inventory control, diagnosis and management of complex networks with queu-ing, capacity constraints, stock replenishment, and the ability to relate operational performance to nancial performance. Littlefield is an online competitive simulation of a queueing network with an inventory point. Start studying LittleField Simulation 1 & 2 Overview. We calculate the reorder point where you set up the model and run the simulation. 3 main things involved in simulation 2. Related research topic ideas. 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. If actual . 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.

Having more machines seemed like a win-win situation since it does not increase our expenses of running the business, yet decreases our risk of having lead times of over a day. 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. 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. At the end of the final day of the simulation we had 50 units of inventory left over Cash Balance: $ 2,242,693 Days 106-121 Day 268 Day 218-268 Day 209 Focus was to find our EOQ and forecast demand for the remaining days, including the final 50 days where we were not in control. .o.
