Using the SPT (shortest processing time) decision rule for sequencing the jobs, the order is (to resolve a tie, use the order in which the jobs were received): Sequence 1 Job The following jobs are waiting to be processed at Rick Solano's machine center. Solano's machine center has a relatively long backlog and sets a fresh schedule every 2 weeks, which does not disturb earlier schedules. Below are the jobs to be scheduled today, which is day 241 (day 241 is a work day). Job names refer to names of clients and contract numbers. Compute all times based on initiating work on day 241. 2 3 4 5 ... The total flow time for the sequence developed using the SPT rule = days (round your response to two decimal places). The percentage utilization for the sequence developed using the SPT rule = ☐ % (enter your response as a percentage rounded to two decimal places). The average number of jobs in the system for the sequence developed using the SPT rule = jobs (round your response to two decimal…

Using the FCFS rule for scheduling, the sequence is 1-2-3 For the schedule developed using the FCFS rule, the total length of time taken to complete the three suits (including delivery) : hours (enter your response as a whole number). = G Sunny Park Tailors has been asked to make three different types of wedding suits for separate customers. The table below highlights the time taken in hours for cutting and sewing (process 1) and delivery (process 2) of each of the suits.
