Solve the question below- except that availability = 95%.
In a sequential batch machining operation, setup time is 1.5 hours, and the batch size is 120 units. The cycle time consists of part handling time of 30 sec
and processing time of 2.85 min. One part is produced each cycle. Tool changes must be performed every 10 parts, and this takes 2.0 min. Determine the
average production rate.

ILLUSTRATION 2: An operator manufactures 50 jobs in 6 hours and 30 minutes. If this time
includes the time for setting his machine. Standard time allowed for the job was:
Setting time = 35 min
Production time per piece = 8 min

What is the minimum number of customers that must be in the system in order for the lead-time (LT) to exceed the raw processing time? Round to one decimal place.arrow_forwardAn emergency situation has arisen in the milling department, because the ship carrying a certain quantity of a required part from an overseas supplier sank on Friday evening. A certain number of machines in the department must therefore be dedicated to the production of this part during the next week. A total of 1000 of these parts must be produced, and the production cycle time per part = 16.0 min. Each milling machine used for this rush job must first be set up, which takes 5.0 hr. A scrap rate of 2% can be expected. Assume availability = 100%. (a)If the production week consists of 10 shifts at 8.0 hr/shift, how many machines will be required? (b)It so happens that only two milling machines can be spared for this emergency job, due to other priority jobs in the department. To cope with the emergency situation, plant management has authorized a three-shift operation for six days next week. Can the 1000 replacement parts be completed within these constraints?arrow_forward
- In a factory where there are three shifts: The machine overhead cost is found to be £8.20 / hr, the labour overhead cost is found to be £30.20/hr, and the premises overhead cost is found to be £3.50/hr.
