Littlefield Simulation Report Essay - 1541 Words

Executive Summary Our team operated and managed the Littlefield Technologies facility over the span of 1268 simulated days. Our team finished the simulation in 3rd place, posting $2,234,639 in cash at the end of the game. We did intuitive analysis initially and came up the strategy at the beginning of the game. 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 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. The Plan - Initial Strategy Our team’s†¦show more content†¦If we change batch size to 1*60, based on day1-50 data, the lead time is always 0.3, and we could not use contract number 2Contract 2 to increase revenue and still have to use Ccontract number 11 Revenue will be the same as 1 which is $1,596,000 . c. If we buy machine 3 because its a bottleneck, without changing anything else, utilization for station 3 will become less which will cause less queue, less waiting time, less lead time, no or less penalty, more revenue. Revenue (roughly) = 12 * 1500 * (268-135) = 12*133*1500 = $2,394,000 Machine cost = 100,000 $2,394,000-$100,000 = $2,294,000 $1,596,000 According to our analysis, So , c) is a betterthe optimal choice whichchoice, which confirmed our aggressive machine buying strategy since Day 135. And on Day 149, and Day 170, we immediately bought machine for station 2 and 1 again when the stationsit becomes bottle neck or when lead time is more than 0.28 which caused revenue decreased to $1,200. 3. Changing lot size : We changed lot size for 3 times. On Day 58, we changed to 2 lots/job in order to take Contract number 2 to make earn more money. On Day 64, we changed to 3 lots/job and hope the lead time would decrease. This was a big mistake we made. After this change, we noticed the queue for station #3 is very high, station #3 became bottleneck and ourShow MoreRelatedLead Time Management at Littlefield Labs642 Words   |  3 PagesLead Time Management at Littlefield Labs Background Littlefield Laboratories has opened a new blood testing lab.

The account includes the decisions we made, the actions we took, and their impact on production and the bottom line. Day 53 Our first decision was to buy a 2nd machine at Station 1. We did not have any analysis or strategy at this point. Nonetheless, this turned out to be a wise investment, since Station 1 was in danger of becoming a bottleneck in productionRead MoreCivic and Citizenship Education in Malaysia2711 Words   |  11 Pagesbecause, according to the Cabinet Committee Report Review Committee on Education, Ministry of Education, 1979 (known as the Cabinet Report 1979), the teaching and learning of civic found to be performed satisfactorily.

Perhaps our acts of perceiving and observing create much what we assume to be ‘out there’ rather than report what ‘is’ – a very different philosophical stance. This issue becomes evident when we turn to what is meant by the term organization below. In sum, theories are highly influential upon what we do and why we do it. Theories allow us to see the world
