Table 3 shows the process sequence in a production line and its related direct time study data. The production process must follow a specific route of processes A, B, C, and D respectively. Task A is in full automatic mode and requires one operator at the workstation. The worker at task B was rated with 90%, the worker at task C was rated with 115% and the worker at task D was rated with 80%. The standard allowances accepted by the company are 6% for fatigue, 5% for personal, and 4% for delay. The normal operating period is 8 hours per day and 24 days per month. Analyse the given information and determine the standard time for the product in minutes.

= Consider a four aisle AS/RS in which an S/R machine is used for each aisle. The length of the storage aisle 85 m and its height = 14 m. Suppose horizontal and vertical speeds of the S/R machine are 61 m/min and 23 m/min, respectively. The S/R machine requires 20 s to accomplish a P&D operation. The aisles in the AS/RS will be organized to follow a class-based dedicated storage strategy. There will be two classes, according to activity level. The more active stock is stored in the half of the rack system that is located closest to the input/output station, and the less active stock is stored in the other half of the rack system farther away from the input/output station. Within each half of the rack system, random storage is used. The more active stock accounts for 80% of the transactions, and the less active stock accounts for the remaining 20%. Assume that system utilization = 90%, and the number of single-command cycles = the number of dual-command cycles. Determine the throughput…

(c) What are the respective idle minutes per cycle for each (man and machine) based on an assignment of one machine? Eight machines?
Suppose a process has been monitored daily for the last ten days and the number of machine failures each day was noted. The results follow: Day Number: 1 2 3 4 5 6 7 8 9 10 Number of Failures: 8 9 6 10 12 4 9 11 9 12 Compute control limits for a c-chart that monitors the average number of machine failures per day. Is the process in a state of control?

The analyst in the Dorben Company wishes to assign a number of like facilities to an operator based on minimizing the cost per unit of output. A detailed study of the facilities revealed the following: Loading machine standard time = 0.30 minutes Unloading machine standard time = 0.25 minutes Walk time between two machines = 0.09 minutes Operator rate = $12.00 per hour Machine rate (both idle and working) = $18.00 per hour Machine cycle time = 1.55 minutes TEC = The Expected Cost a) With your initial estimation, how many machines can be serviced exactly?(please keep a non-integer with three decimal places) b) How much is your TEC per piece if the operator has idle time? (please keep three decimal places) c)How much is your TEC per piece if the machine has idle time? (please keep three decimal places) d) How many of these machines should be assigned to each operator?(please write down a numerical number)

Consider the following tasks that must be assigned to four workers on a conveyor-paced assembly line (i.e., a machine-paced line flow). Each worker must perform at least one task. There exists unlimited demand unless stated otherwise. Time to Complete Task (seconds): Task 1: 30 Task 2: 25 Task 3: 15 Task 4: 20 Task 5: 15 Task 6: 20 Task 7: 50 Task 8: 15 Task 9: 20 Task 10: 25 Task 11: 15 Task 12: 20 The current conveyor-paced assembly-line configuration assigns the workers in the following way: • Worker 1: Tasks 1, 2, 3 • Worker 2: Tasks 4, 5, 6 • Worker 3: Tasks 7, 8, 9 • Worker 4: Tasks 10, 11, 12 What is the capacity of the current line (in units per hour)?
