K Courtney is a programmer receiving requests each week to analyze a large data base. Five jobs were on her desk Monday morning, and she must decide in what order to write the code. Assume that all jobs arrived today (day 1 and hour 1), in the order shown below. Courtney has assigned the number of hours required to do the coding as noted. Note that Courtney works an 8-hour day and today is a work day. JOB A C D E DUE DATE (HOURS HENCE) 10 16 14 36 26 DURATION (HOURS REQUIRED) 6 3758 a) Sequence the jobs according to EDD. According to the EDD rule, the sequence of jobs should be A, C, B, E, D b) What is the average completion (flow) time? The average completion (flow) time is days (round your response to one decimal place).

Five jobs are ready for processing at time zero through a workstation. The details of the processing time and the due date of completion is provided in the following table. Job A B Processing Time (days) I5 Due Date 11 6 3 16 19 10 D E 15 Using the earliest due date (EDD) rule, the average lateness for the five jobs is decimal place. Round your answer to one Your Answer: Answer

What is the answer

Five customers brought in computers to be repaired to a small shop. Estimated repair times (in days) and dates promised are given below. Due dates were set based on available technicians; however, one technician had a medical emergency and will be unavailable for at least two weeks so processing times were adjusted. Customer job 1 Processing time (days) Due date (days) 6 Use the EDD rule and compute the start time, flow time, lateness, and tardiness for each job. Use minus sign to enter negative lateness values, if any. If your answer is zero, enter "0".
