janitorial service, Mother’s Helpers, provide workers to clean office buildings during late evening hours using workers with two skill levels, 1 and 2. Each level 1 person is paid $12 per hour and each level 2 person is paid $8 per hour. The workers wash floors and vacuum offices. Each level 1 person can vacuum 9 offices per hour, whereas level 2 person can vacuum only 2 offices per hour. Each level 1 person can wash 2 floors per hour; whereas level 2 person can wash 3 floors per hour. In order to complete a new job in the allotted time, 18 offices must be vacuumed per hour and 12 floors must be washed per hour.

Jennifer supervised 50 employees in 5 departments. She sent a memo to her team in order to be efficient and cut costs of unnecessary overtime. The message was the following: “When workloads increase to a level requiring hours in excess of an employee’s regular duty assignment, and when such work is estimated to require a full shift of eight hours or more on two or more consecutive days, even though unscheduled days intervene, an employee’s tour of duty shall be altered so as to include the hours when such work must be done, unless an adverse impact would result from such employee’s absence from his previously scheduled assignment”. After the 50 copies were sent out, Jennifer’s office received 40 phone calls asking what the memo meant. The 10 employees left did not call but their thoughts about the memo is uncertain. It took two weeks to clarify the new policy. What is the main problem that the supervisor is trying to solve? What is the purpose of the message: to inform, persuade,…

The topic is about Quantitive analysis and decision making. Problem: A firm just completed a new plant that will producemore than 500 different products, using morethan 50 different production lines and machines.The production scheduling decisions are criticalin that sales will be lost if customer demands arenot meet on time. If no individual in the firmhas experience with this production operationand if new production schedule must begenerated each week, why should the firmconsider a quantitative approach to theproduction scheduling problem?
A leatherworks factory has two punch presses for punching holes in the various leathergoods produced in the factory prior to sewing. Suppose that 12 different jobs must beprocessed on one or the other punch press (i.e., parallel processing). The processingtimes (in minutes) for these 12 jobs are given in the following table.Job 1 2 3 4 5 6 7 8 9 10 11 12Time 26 12 8 42 35 30 29 21 25 15 4 75Assume that both presses are initially idle. Compare the performance of SPT andLPT (longest processing time) rules for this example. (In parallel processing the nextjob is simply scheduled on the next available machine.)
In an evaluation of labor assignment rules when workers are not perfectly interchangeable, Paul. M. Bobrowski and Paul Sungchil Park created a dynamic job shop with 9 work centers and 9 workers, both numbered 1–9. The efficiency of each worker is specified in the following labor efficiency matrix, which represents the degree of worker cross-training.† Work Centers 1.00 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 1.00 W o r k e r s (a) For what work center(s) is worker 2 least efficient?
