QUESTION TWO (15 MARKS) (a.) A hotel has two wings, an east wing and a west wing. Each wing has four 'room service maids' working seven-hour shifts to service the rooms each day. The east wing has 40 standard rooms, 12 deluxe rooms and 5 suites. The west wing has 50 standard rooms and 10 deluxe rooms. The standard times for servicing rooms are as follows: standard rooms 20 standard minutes, deluxe rooms 25 standard minutes, and suites 40 standard minutes. In addition, an allowance of 5 standard minutes per room is given for any miscellaneous jobs such as collecting extra items for the room or dealing with customer requests. What is the productivity of the maids in each wing of the hotel? What other factors might also influence the productivity of the maids? (b.) In the problem above, one of the maids in the west wing wants to job-share with her partner, each working three hours per day. Her colleagues have agreed to support her and will guar- antee to service all the rooms in the west wing to the same standard each day. If they succeed in doing this, how has it affected their productivity? QUESTION THREE (15 MARKS) A laboratory process receives medical samples from hospitals in its area and then subjects them to a number of tests that take place in different parts of the laboratory. The average response time for the laboratory to complete all its tests and mail the results back to the hospital (measured from the time that the sample for analysis arrives) is three days. A recent process map has shown that, of the 60 minutes that is needed to complete all the tests, the tests themselves took 30 minutes, moving the samples between each test area took 10 min- utes, and double checking the results took a further 20 minutes. What is the throughput effi- ciency of this process? What is the value-added throughput efficiency of the process? (State any assumptions that you are making.) If the process is rearranged so that all the tests are performed in the same area, thus eliminating the time to move between test areas, and the tests themselves are improved to half the amount of time needed for double checking, what effect would this have on the value-added throughput efficiency? QUESTION FOUR (15 MARKS) The regional government office that deals with passport applications is designing a process that will check applications and issue the documents. The number of applications to be processed is 1,600 per week and the time available to process the applications is 40 hours per week. (a) What is the required cycle time for the process? (b) If the total work content of all the activities that make up the total task of checking, processing and issuing a passport is, on average, 30 minutes, how many people will be needed to meet demand? (c) The passport office has a 'clear desk policy that means that all desks must be clear of work by the end of the day. How many applications should be loaded onto the process in the morning in order to ensure that every one is completed and desks are clear by the end of the day? (Assume a working day of 7.5 hours (450 minutes).)
