- The first five columns of the following table contain information about a set of four jobs that just arrived (end of Hour 0 or beginning of Hour 1) at an engine lathe. They are the only ones now waiting to be processed. Several operations, including the one at the engine lathe, remain to be done on each job. Determine the schedule by using (a) the CR rule and (b) the S/RO rule. Compare these schedules to those generated by FCFS, SPT, and EDD.

Open the spreadsheet and perform the required analysis to answer the questions below. Questions 1. Use the shortest-processing-time (SPT) sequencing rules to sequence the jobs. Compute the flow time, tardiness, and lateness for each job, and the average flow time, average tardiness, and average lateness for all jobs. Use minus sign to enter negative lateness values, if any. Round the average values to two decimal places. Sequence Job Processing Time Due Date Flow Time Lateness Tardiness 1 2 3 4 5 Average 2.

- The Security Life Insurance Company processes all new life insurance policies through three departments: incoming mail (I), underwriting (U), and policy control (P). Theincoming mail department receives applications and customer payments and then routes the files to the underwriting department.
