Five sorority sisters plan to attend a social function. Each requires hair styling andfitting for a gown. Assume that the times required are independent exponentiallydistributed random variables with the mean times for the fittings of 0.6, 1.2, 1.5,0.8, and 1.1 hours, respectively, and mean times for the stylings of 0.8, 1.6, 1.0,0.7, and 1.3 hours, respectively. Assume that the fittings are done before thestylings and that there is only a single hair stylist and a single seamstress available.In what sequence should they be scheduled in order to minimize the total expectedtime required for fittings and stylings?

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?
The chief of police, Karen Stanley, of the Make-BelievePolice Department needs to assign five detective squadsto five pending criminal cases. Karen wants to comeup with an optimum assignment that will minimize thetotal time it takes to conclude the cases. Data on past performance of each detective squad to complete each case assigned in terms of average number of days ispresented in the following table.Average Completion Time (in Days)Detective Squad Case-1 Case-2 Case-3 Case-4 Case-5A 15 8 4 8 28B 21 8 13 7 32C 11 4 5 6 20D 9 12 8 13 20E 14 24 25 27 9Use the assignment method to solve the problemIf Squad D cannot be assigned to Case-5 as a result ofa conflict of interest, solve the problem given this new constraint.
Many business schools are increasing their offerings of internship and study abroad programs. In fact, some schools are requiring an internship and/or international study program as part of business degree requirements. They believe that on-the-job experience and global studies increase students’ knowledge base and employability. Consider the following variables for completing (1) an internship and (2) a study abroad program: costs (e.g., tuition, program fees, travel, lodging, food, and so on), timing (when these experiences are available and can be fit into your college years), options offered by your business school, and outcomes (how your preferences support your personal and professional growth). Construct a chart and then summarize the best plan for you to complete these experiences
Mike Reynolds has four assignments due in class tomorrow, and his class times are as follows: Class Time Marketing 304 9 a.m. OM 385 12 p.m. Finance 216 2 p.m. Psychology 200 5:30 p.m. Each class lasts one hour, and Mike has no other classes. It is now midnight, and Mike estimates that the finance, OM, marketing, and psychology assignments will take him two, three, five, and four hours, respectively. Assume that all time till the last class begins can be spent on completing assignments but each assignment should be done till the time of the class on the same subject. (Mike can prepare assignments for the next classes during previous classes.) Use the Excel to determine how he should schedule the work. Use minus sign to enter negative lateness values, if any. Enter the half an hour value as 0.5, e.g., 3:30 p.m. should be entered as 15.5. If your answer is zero, enter "0". Round your answers for the due date, lateness, and tardiness to one decimal place.

One possible solution method for the machine-tojob assignment problem is the following heuristic procedure. Assign the machine to job 1 that completes job 1 quickest. Then assign the machine to job 2 that, among all machines that still have some capacity, completes job 2 quickest. Keep going until a machine has been assigned to all jobs. Does this heuristic-procedure yield the optimal solution for this problem? If it does, see whether you can change the job times so that the heuristic does not yield the optimal-solution.
Please formulate the problem as AN OPTIMIZATION MODEL only and I will finish the rest. Health Center is planning to open its facilities 24 hours a day and wants to determine an optimal schedule. for their nurses. A nurse's work schedule is 8 hours in a row and can only start at the beginning of each shift. The personnel requirement for each shift is shown in Table 1. Table 1 – Personnel Requirement
A restaurant operates from 8 a.m. to 8 p.m. and employs both full-time and part-time workers. Full-time workers work from 8 a.m. to 6 p.m., 9 a.m. to 7 p.m., or 10 to 8 p.m. and are paid $140 per day. Part-time workers work either 12 p.m. to 6 p.m. or 1 p.m. to 7 p.m. and are paid $85 per day. The number of employees needed every hour is as follows.

The Baton Rouge Police Department has five detectivesquads available for assignment to five open crime cases. Thechief of detectives, Jose Noguera, wishes to assign the squads sothat the total time to conclude the cases is minimized. The averagenumber of days, based on past performance, for each squad tocomplete each case is as follows: Each squad is composed of different types of specialists, andwhereas one squad may be very effective in certain types of cases,it may be almost useless in others.a) Solve the problem by using the assignment method.b) Assign the squads to the above cases, but with the constraintthat squad 5 cannot work on case E because of a conflict.
Lee Beedo, a hip bachelor in Edmond, has a date for Saturday night and finds himself without a thing to wear. Faced with the daunting task of doing enough laundry to fully accessorize during his night out, Lee has sorted his clothes into loads according to fabric and color. Based on his vast experience doing laundry, Lee knows how long each load will take in both the washer and the dryer. He glances at his watch; it is now 2:00 p.m. and he has to have the last load dry by 8:30 p.m. to be there in time. Help Lee develop a schedule that will enable him to make his date on time and depict that schedule using a Gantt chart. Can he make it and, if so, by how much?
