- Question Scenario: Early one Monday morning in Jamaica, Susan, a Restaurant Manager starts getting ready for the morning’s work operations. She is particularly happy because tonight he has a date with Marvin, the new Chef that was recently hired. The problem, as Susan sees it, is that Roberta, another Restaurant employee has been just a little too friendly with Marvin lately and that really upsets Susan. Susan has redone the work schedule, assigning Roberta the clean-up shift in the night and cutting back on her hours of work. She is hoping that Roberta would simply quit and out of her way. However, that plan doesn’t seem to be working. Despite a lighter pay cheque and frequent reprimand through the disciplinary process of creating reasons to write to her about her conduct and performance. Roberta has decided to quit her studies due to her inability to fund her tuition. A few days later, Susan noticed Marvin and Roberta having lunch together in the staff dining room. Susan got furious…arrow_forwardQuestion 34 Consider the processing times and priorities for four jobs: Job Processing time (minutes) Weight/Priority (cost per minute) A 10 6 B 2 1 C 50 2 D 16 10 Assume the weighted shortest processing time (WSPT) rule is used.

- Question3: Two processes are applied in the same order to the jobs coming to a workstation. The durations of both processes for the six jobs coming to the workstation are as seen in the table. In order to minimize the total time to be spent on the jobs, the order in which the jobs should be done will be determined by the "johnson" rule. Accordingly, in the table below, write the order in which the business should do the work, in order, with the first things to be done on the far left, and one action to be written in each blank.1-) When the jobs are done in this order, how many minutes will it take to complete all the jobs?2-)1.
