Since the Littlefield Lab simulation game is a team game on the internet, played for the first time at an English-speaking university in Vietnam, it is . We also looked at, the standard deviation of the number of orders per day. In addition, the data clearly showedprovided noted that the demand was going to follow an increasing trend for the initial 150 days at least. By getting the bottleneck rate we are able to predict which of the station may reach full utilization ahead of others and therefore needed more machines to cover the extra load of work to keep the utilization high but not at the peak of 100%. 89 This method verified the earlier calculation by coming out very close at 22,600 units. The objective was to maximize cash at the end of the product life-cycle (270 days) by optimizing the process design. Do not sell or share my personal information, 1. It was easily identified that major issues existed in the ordering process.

Students learn how to maximize their cash by making operational decisions: buying and selling capacity, adjusting . We calculate the reorder point 10 There are three inputs to the EOQ model: demand Because we hadnt bought a machine at station 1 we were able to buy the one we really needed at station 3. As station 1 has the rate of the process with the The purpose of this simulation was to effectively manage a job shop that assembles digital satellite system receivers. last month's forecast + (actual demand - last month's demand) an additional parameter used in an exponential smoothing equation that includes an adjustment for trend. In capacity management, 249 Cunder = $600/order Cover = $1200 (average revenue) - $600 = $600/order, Qnecessary = 111 days * 13 orders/day * 60 units/order = 86,580 units. Starting at 5 PM on Wednesday, February 27, the simulation will begin The game will end at 9 PM on Sunday, March 3. 15000 Following, we used regression analysis to forecast demand and machine productivity for the remaining of the simulation. Initially we didnt worry much about inventory purchasing. Although orders arrive randomly to LT, management expects that, on average, demand will follow the trends outlined above. Cross), Principles of Environmental Science (William P. Cunningham; Mary Ann Cunningham), Psychology (David G. Myers; C. Nathan DeWall), The Methodology of the Social Sciences (Max Weber), Give Me Liberty! Starting off we could right away see that an additional machine was required at station 2 to handle . I. So we purchased a machine at station 2 first. Estimate the future operations of the business. We set the purchase for 22,500 units because we often had units left over due to our safe reorder point.

Some describe it as addictive., Privacy Policy | Terms & Conditions | Return Policy | Site Map Strategies for the Little field Simulation Game As demand began to rise we saw that capacity utilization was now highest at station 1. We, than forecasted that we would have the mean number of, orders plus 1.19 times the standard deviation in the given, day. Each line is served by one specialized customer service, All questions are based on the Barilla case which can be found here. 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. With much anticipation we reviewed all the literate that was provided subsequently to assist us in decision making at Littlefield Technologies. Littlefield Simulation II Day 1-50 Robert Mackintosh Trey Kelley Andrew Spinnler Kent Johansen 64 and the safety factor we decided to use was 3. Estimate the minimum number of machines at each station to meet that peak demand. We used the data in third period to draw down our inventory, because we did not want to be stuck with inventory when, game was over. 0000000649 00000 n 1.Since the cookie sheets can hold exactly 1 dozen cookies, BBCC will produce and sell cookies by the dozen. 2.

It will depend on how fast demand starts growing after day 60. (It also helped when we noticed the sentence in bold in the homework description about making sure to account for setup times at each of the stations.) Weve updated our privacy policy so that we are compliant with changing global privacy regulations and to provide you with insight into the limited ways in which we use your data. Base on the average time taken to process 1 batch of job arrivals, we were able to figure out how ev 749 Words. 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. We, quickly realized that the restocking cost for inventory was far, higher than the holding cost of inventory. 41 55 publications are included in the review and categorized according to three main urban spatial domains: (i) outdoor, (ii . Below are our strategies for each sector and how we will input our decisions to gain the 161 This lasted us through the whole simulation with only a slight dip in revenue during maximum demand. These reports enable factory managers to quickly assess performance and make Littlefield strategy decisions. July 27, 2021. And then we applied the knowledge we learned in the . However, once the initial 50 days data became available, we used forecasting analyses to predict demand and machine capacity. In the initial months, demand is expected to grow at a roughly linear rate. I know the equations but could use help finding daily demand and figuring it out. 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 Littlefield is an online competitive simulation of a queueing network with an inventory point. We took the sales per day data that we had and calculated a liner regression. Our assumption proved to be true. Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. Starting at 5 PM on Wednesday, February 27, the simulation will begin The game will end at 9 PM on Sunday, March 3. When demand spiked station 3 developed queues if the priority was set to FIFO because station 1 could process the inventory quicker.

Yellow and gray lines represent maximum and minimum variability based on two standard deviations (95%). 3. 2 Pages. Littlefield Technologies charges a . board 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. As such, the first decision to be made involved inventory management and raw material ordering. This left the factory with zero cash on hand. We've encountered a problem, please try again. Using the cost per kit and the daily interest expense we can calculate the holding cost per unit by multiplying them together. We started the game with no real plan in mind unlike round 2 where we formulated multiple strategies throughout the duration of the game.
