Six ships are docked in a harbor awaiting unloading. The times required to unload the ships are random variables with respective means of 0.6, 1.2, 2.5, 3.5, 0.4, and 1.8 hours. The ships are given a priority weighting based on tonnage. The respective tonnages are 12, 18, 9, 14, 4, and 10. In what sequence should the ships be unloaded in order to minimize the expected weighted time?

Codeword
Codeword is a medium-size firm that designs and manufactures electronic systems for the mass transit industry. It competes with other firms to win contracts to provide such systems. When Codeword receives a contract, it creates a project to complete the work. Most projects range from $10 million to $50 million in cost and from one to three years in duration. Codeword can have 6 to 12 projects going on at any one time, in various stages of completion—some just starting and others finishing.
Codeword has a handful of project managers who report to the general manager; other people report to their functional manager. For example, the electronics engineers all report to the manager of electrical engineering, who reports to the general manager. The functional manager assigns particular individuals to work on various projects. Some people work full-time on a project, whereas others split their time among two or three projects. Although individuals are assigned to work for a project…

- The Mechanical Engineering department has a student team that is designing a formula car for national competition. The time required for the team to assemble the first car is 100 hours. Their improvement (or learning rate) is 0.8, which means that as output is doubled, their time to assemble a car is reduced by 20%. Use this information to determine: the time it will take the team to assemble the 10th car. Create an excel spreadsheet having the following table. You must show the formula used in the excel sheets to calculate values in the columns. Plot Number of Units vs Time (in hours) and Number of Units vs Cumulative Time (in hours) in the same plot.

- Author: Leo A. Ruggle, Professor, Department of Accounting, Mankato State University Arnie Armstrong has been with Pierce Auto Parts Manufacturing Company for 23 years. Recently, he was appointed Director of Manufacturing Computer Services. In just six weeks in this new position, [he] has moved to reduce the amount of information provided to manufacturing department managers by 60 percent. He argues that excess data is distracting, unused, and expensive to provide. Willy McClean has been department manager for 12 years. During a coffee break with some of his department production supervisors, Willy is quite vocal about the change. “Who’s this guy Armstrong to tell us what data we need? He needs to be out here for a few weeks to find out what it’s like.

- Five to six times a year, Kicker puts on tent sales in various cities throughout Oklahoma and the surrounding states. The tent sales are designed to show Kicker customers new products, engender enthusiasm about those products, and sell soon to be out-of-date products at greatly reduced prices. Each tent sale lasts one day and requires parking lot space to set up the Kicker semitrailer; a couple of show cars; a disc jockey playing music; a tent to sell Kicker merchandise, distribute brochures, and so on. Last year, the Austin, TX tent sale was held in a corner of the parking lot outside the city exhibition hall where the automotive show was in progress. Because most customers were interested more in the new model cars than in the refurbishment of their current cars, foot traffic was low. In addition, customers did not want to carry speakers and amplifiers all the way back to where they had originally parked. Total direct costs for this tent sale were $14,300. Direct costs…arrow_forwardAt a manufacturing assembly line, 30 jobs arrive perhour. Each job must pass through two production stages:stage 1 and stage 2. Stage 1 takes an average of 1 minute tocomplete, and 1 worker is available to perform stage 1.After completing stage 1, the job immediately passes tostage 2. Stage 2 takes an average of 2 minutes to complete,and 2 workers are available to work on stage 2. Aftercompleting stage 2, each job is inspected. Inspection takesan average of 3 minutes, and 3 workers are available toperform inspection. After inspection, 10% of the jobs mustbe returned to stage 1, and they then repeat both stages 1and 2. After inspection, 20% of all jobs return to stage 2 andrepeat stage 2.

- Mr. Ajit currently serves at a senior director with BSNL Mumbai. In his brigade of staff there are 10 supervisors and more than 200 telephone assistance operators. If any resident wants to call 197 for directory assistance ,he would be speaking with one of the employees from BSNL. Within this organisation the position of a telephone assistance operator requires high standards of communication ,a pleasant tone, good voice quality and familiarity with the company’s computer operator directories and software. The assistant also needs to be proactive in answering other queries asked by the caller. A major issue that is seen is that a lot of telephone assistance operators tend to leave the organisation , that turnover rates are high and people look unwilling. Mr. Ajit has noticed that upon joining, these telephone operators do not receive any detailed training. Being that it's a very busy workplace, these operators are given a short tour of the office and a five-page printed sheet that…arrow_forwardConsider a manufacturing process depicted by the following flowchart. flowchart Station A has 3 parallel operators, A1, A2, and A3. Station C has 2 parallel operators, C1 and C2. Each unit only needs to be processed by one of the operators A1, A2 and A3. After being processed at Station B, a unit then needs to be processed by either C1 or C2. The process time of the individual operators are given as follows. A1, A2, and A3: 12 minutes B: 14 minutes C1 and C2: 6 minutes. The process initiates the production of a new unit every 18 minutes. What is the utilization of Operator C2 in percentage? Note: Provide a number without the % mark. Round your final answer to 2 decimal places if it is not a whole number.arrow_forwardYou are the project manager for a construction project (maybe capstone design) and you must schedule the various jobs which must be completed before the project is finished. Some of the jobs can begin immediately but other jobs can only begin after others are completed. For example, grading can begin immediately but laying a foundation must be delayed until the grading is completed. The data below are for a project which includes ten jobs; the time it takes to complete each job is known and the set of jobs which must be completed before each job can begin is known. Your objective is to find a schedule (i.e. beginning times and ending times) for all of the jobs such that no jobs begins before any of its predecessors are completed and the time when all jobs are finished is minimized. Formulate a linear programming model to solve the problem. For the following problem, formulate the Linear program or LP as follows: 1) Define the decision variables and briefly explain the significance of…arrow_forward
