After the initial observations of demand for littlefield labs (day 52), one of the first steps we took was to identify the bottleneck in the production chain. This was determined by looking at the rate of utilization of the three machines and the number of jobs in the queue waiting for these machines. It was quickly determined that the machine 1 was our bottleneck, as it was the only machine with 100% utilization and excess number of jobs in the queue. This meant that machine 1 was not able to keep up with the incoming demand and lacked the proper capacity. We knew that we needed to increase capacity and the decision was made to purchase another machine 1.
Following the decision to purchase a machine, our focus shifted to the inventory

Using the excel spreadsheet and looking at the linear regression line, we determined that the approximate level of demand on day 120 would be about 18 kits per day. This number was critical to our overall strategy going forward. Since we knew the demand would average around 18 kits a day, we wanted to have enough capacity in the machines to handle the demand. We figured to calculate the demand capacity of each machines by looking at the level of utilization of each machines on day 1, when the very first order arrived. Using the percentage of utilization and the actual number of job coming in for the first time, we were able to calculate the capacity of each machine with relative accuracy. It was determined that machine 1 had the capacity of 4.5 jobs per day, machine 2 with capacity of 12.5 jobs per day, and machine 3 with capacity of 12jobs per day. This meant that in order for us to accommodate the expected level of demand, we needed to have five units of Machine 1, two units of Machine 2, and two units of Machine 3. We wanted to have five units of Machine 1 because we did not want to have just 4 and have 100% utilization, causing a bottleneck situation.
We also wanted to figure out the optimal reorder point and order quantity using the forecasted average demand of 18 jobs per day. We set the number of reorder point to 95 kits, accounting for the four day lead period and the level of safety stock we wanted to have.
The second Littlefield simulation game focused on lead time and inventory management in an environment with a changing demand (“but the long-run average demand will not change over the product’s 268-day lifetime”). Therefore our strategy to win this game was controlling the Littlefield Lab’s system capacity and the inventory level with choosing a right contract as well as keeping the cash daily as much as possible. In other

Oakland fell into the Alternative Education Law program. Students worked at their own pace and speed to complete school. Oakland High School generally graduated between 15-20 students a year. Several smaller programs existed within the school, such as Region 5, or ALC (Alternative Learning Center) program or Lincoln Tree Farm. Region 5 were for student who were in transition from just being released from either Echo Glenn or Green hill youth jail facilities. They worked with a JRA representatives and would complete school work and prepare to reenter the comprehensive high school setting. They would have no contact with the remainder of the building and programs. This program ended during the 2007-2008 school year.
Matt Lamkin’s “A Ban On Brain-Boosting Drugs is Not the Answer” first appeared in Chronicle of Higher Education in 2011. In this essay Lamkin aims to convince his reader not to deter improper conduct with threats, but to encourage students to engage in the practice of education. Lamkin tells us “If colleges believe that enhancing cognition with drugs deprives students of the true value of education, they must encourage students to adapt that value as their own” (642). Appeal to logic, consistency, and compare/contrast are techniques Lamkin skillfully uses to create a strong effective essay.
We then determined our best course of action would be to look at our average daily revenue per job (Exhibit 7) and see if we could identify any days when that was less than the maximum of $1,000/job, so we could attempt to investigate what days to check on for other issues. We noticed that around day 31, revenues dipped slightly, despite the fact that the simulation was still nowhere near peak demand, suggesting that something was amiss in our process.
Glen A. Wilson High School is a four-year comprehensive public high school, grades 9-12th grade. Wilson High School located in Hacienda Heights, California, serves a middle class community of about 54,000 residences, with the median income of $50,000 (www.gwhs-hlpusd-ca-schooloop.com). Wilson has a six-year accreditation from Western Association of Schools and Colleges, as well as being a part of International Baccalaureate Organization. Wilson High School has a total of 42-chartered active clubs and comprehensive interscholastic athletic program in 23 different sports (www.gwhs-hlpusd-ca.schoolloop.com). As of 2014-2015, the total student enrollment is 1616, with 407 seniors, 419 juniors, 377 sophomores, and 395 freshmen (www.gwhs-hlpusd-ca-schooloop.com). The racial/ethnic composition includes 38% Asian, 53% Latino, 5% Caucasian, and 1% African American. The facility consists of one principal, three vice principals, six counselors, including one international student counselor, 57 teachers, one International Baccalaureate coordinator, two-part time psychologists, two ELD program aides, one community Liaison, and a Special Education Coordinator, (www.gwhs-hlpusd-ca-schooloop.com). As shown in Figure 4 there has been a steady decrease in number of enrollments, with over 100 students less than the 2011-2012 school year. In addition there are a total of 922 who were eligible for free and reduced lunches, along with 104 students who were classified as English Learners
Communities are all over the place, multiple people belong to all types of communities. The community I belong to is the community of Fox Hall. I’ve lived in Fox Hall for the whole time I have been attending the University of Massachusetts Lowell. I have met numerous amounts of people and made several friends while living in Fox Hall. Fox Hall is a fascinating building because it has eighteen floors of residence. Fox Hall is the tallest building in Lowell which is very interesting. Since I have been here, I was curious about all the activities that have been going on in Fox Hall. I chose Fox Hall as my residence hall because it offers many opportunities to meet new people and make new friends. I find it important to see how people react during
The assignment method was used in determining ways that the schedule can be change to maximize production while reducing idle time, completion time, and potentially labor costs. Using the information that was provided, Operator A will cost $10.00 for the first job, $11.00 for the second, $9.00 for the third, and $10.00 for the fourth. Operator B will cost $12.00 for the first job, $9.00 for the second job, $8.00 for the third, and $8.00 for the fourth. Operator C similarly will cost $11.00 for the first, $11.00 for the second, $11.00 for the third, and $9.00 for the fourth. Last, Operator D will cost $11.00 for the first, $11.00 for the second, $9.00 for the third, and $10.00 for the fourth. While
At Maryland Elementary School, I have a kindergarten class. Which means the kindergartners don’t know that there is whole new idea of school and knowing that there are rules in a classroom. For the kindergartners, it will be a something new and different because in this stage they will be developing more of their motor skills. Meaning that they will be more active and many times difficult to teach. The kindergarten teacher uses the rules that the school provides the essentials. Which are give it your best, use kind words, be mindful of others thoughts and beliefs, etc. and the teacher implements these rules in the first few days in school. The teacher reminds the students about these rules almost everyday just to put it meaning into those rules.
Revenue maximization:Our strategy main for round one was to focus on maximizing revenue. We did not want the revenue to ever drop from $1000, so we took action based on the utilization rates of the machines. We needed to have sufficient capacity to maintain lead times of less than a day and at most, 1 day and 9 hours. 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. In terms of when to purchase machines, we decided that buying machines as early as possible would be ideal as there was no operating costs after the initial investment in the machine. Having more machines seemed like a win-win situation since it does not
5. How would you go about deciding the appropriate batch size for the Stonehaven factory? What factors would you consider? How do they interrelate? (You may wish to do some calculations, but concentrate on thinking conceptually.)

According our estimation from day 640 to 730, we had the mean 14.098 drums. Hence, we set the capacity number to 15 and let the production non-stop by adjusting higher order number and 200 quantity per truck. Let’s summary our work as the following: Our process: figure out whether we should build factory and warehouse in specific region. estimate the demand of four region and Fargo region, change capacity, adjust order point, quantity, and priority order, check and adjust parameters from time to time
Setup for the machine is done for one batch of items. If we look at the the batch size of valves, it will be 375 units(=7500 units/ 20 production runs)
