A batch production operation has a machine setup time of 4.0 hr and a processing time of 1.50 min per cycle. Three parts are produced each cycle. No tool handling time is included in the cycle. Part handling time each cycle is 30 sec. It consists of the worker obtaining three starting work units from a parts tray, loading them into the machine, and then after processing, unloading the completed units and placing them into the same tray. Each tray holds 27 work units. When all of the starting work units have been replaced with completed units, the tray of completed parts is moved aside and a new tray of starting parts is moved into position at the machine. This irregular work element takes 4.0 min. Batch quantity is 2,700 units.

Determine

(a) average cycle time,

(b) time to complete the batch,

A worker-machine operation was found to involve 4.6 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. The worker’s time averaged 3.1 minutes per cycle, and the worker was given a rating of 121 percent (machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance percentage of 13 percent of work time which is applied only to the worker element (not the machine element), determine...

Evan Schwartz has six jobs waiting to be processed through his machine. Processing time (in days) and due date information for each job are as follows: Job Processing Time Due Date A B C D E F 2 1 5 3 4 7 3 2 12 4 8 11 Sequence the jobs by FCFS, SPT, SLACK, and DDATE. Calculate the mean flow time and mean tardiness of the six jobs under each sequencing rule. Which rule would you recommend?

What factor influences the decision to employ real-time data collection with batch updating rather that purely real-time processing? Explain.

The Tools Company uses a lathe to machine an aluminum block. The operation time is 5 minutes. On average, the lathe requires maintenance after 200 parts. The average maintenance time is about 2 hours. (For the purpose of these calculations, maintenance is the same as failure. A.) What is the production rate of the machine in parts per minute? (Round to 3 decimal places) B.) Continuing from Part 1, the next operation after turning (lathe operation), is a milling operation....

A machine, currently in operation, has a market value of $4000. The machine can still be used over the next three years, but its market value will become $3000, $2500, $2,000 at the end of the first, second, and third years, respectively. The operating expenses of the machine amount to $20,000 during the first year, and will increase by $5,000 each year thereafter. This machine can be replaced by a newer model, which cost $30,000 for installation and will have...
