The management of a drinking water refill station is planning to estimate the average cost of paying technicians to maintain the water refill stations. The management wants their OM to provide normal times and standard times for cleaning a station based on observed values, rating factors (RF), and a 20% allowance.

A foreman has determined the expected processing times at a machine for a set of jobs and now wants to sequence them. Given the following information, do the following: Job Time Due Date Job (days) (days) a 4.5 10 6.0 17 5.2 12 d. 1.6 27 e 2.8 18 f 3.3 19 a-1. Determine the processing sequence using (1) MST, (2) SPT, (3) EDD, and (4) CR. Rule Sequence a-с-b-е-f-d MST d-e-f-a-c-b SPT a-c-b-e-f-d EDD a-c-b-f-e-d O CR a-2. For each sequence, calculate the average days late, the average flow time, and the average WIP. (Do not round intermediate calculations. Round the final answers to 2 decimal places.) Rule Average lateness Average flow time Average WIP day (s) day (5) MST & EDD day(s) jobs day (s) jobs SPT day (s) day (s) jobs CR b. Which rule is best? SPT O has the lowest average flow time & average WIP, but EDD & MST have the lowest average days late.

Using the FCFS (first come, first served) decision rule for sequencing the jobs, the order is: Sequence 1 2 3 4 The total flow time for the sequence developed using the FCFS rule = decimal places). 5 The percentage utilization for the sequence developed using the FCFS rule = rounded to two decimal places). The average number of jobs in the system for the sequence developed using the FCFS rule = response to two decimal places). TL- The average tardiness (job lateness) for the sequence developed using the FCFS rule = to two decimal places). FALL:LL- /: I------ h Job Sequence 1 Using the EDD (earliest due date) decision rule for sequencing the jobs, the order is (to resolve a tie, use the order in which the jobs were received): 2 3 4 days (round your response to two 5 The total flow time for the sequence developed using the EDD rule = decimal places). % (enter your response as a percentage Job The average number of jobs in the system for the sequence developed using the EDD rule =…
