- 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).
