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. After checking on the applicants’qualifications for life insurance, the underwriting department forwards the file to policy control for the issue of the policy. At the present time, the company has five new policy applications waiting to be processed. The time required for processing in each department is shown below. Policy Department/Hours 1 I/3, U/6, P/8 2 I/2, P/10 3 I/1, U/3, P/4 4 I/2, U/8, P/6 5 I/1, P/6a. Prepare a Gantt chart schedule for these policies.
In a few words, explain how to prevent a process getting starved in priority scheduling.

- How do you schedule 100 regular manufacturing employees working four to six-hour shifts and three skilled employees on a typical plant process? Each machine and employee must be scheduled over the day and the standard time for planning is an hour?arrow_forwardAn order for 100 of a product is processed on operation A and operation B. The setuptime on A is 50 minutes, and the run time per piece is 9 minutes. The setup time onB is 30 minutes, and the run time is 6 minutes per piece. It takes 20 minutes to movea lot between A and B. Since this is a rush order, it is given top priority (president’sedict) and is run as soon as it arrives at either workstation.It is decided to overlap the two operations and to split the lot of 100 into two lotsof 60 and 40. When the first lot is finished on operation A, it is moved to operation Bwhere it is set up and run. Meanwhile, operation A completes the balance of the 100units (40) and sends the units over to operation B. These 40 units should arrive asoperation B is completing the first batch of 60; thus, operation B can continue withoutinterruption until all 100 are completed.a.

See the flowchart below .Small tables are made in batches of 100, and large tables are made in batches of 50. A batch includes a fixed setup time for the entire batch at each process step and a run time for each piece in the batch. Both large and small tables have the same processing times. The capacities of each process step are given, and apply to production of either type of table, as shown in the flowchart. a. What is the capacity of the system, and what is thebottleneck? b. What are the throughput times for batches of large and small tables? c. When producing at a rate of six small tables per hour on average, how many tables will be in the system?arrow_forward
