Compute Lead Time Jackson Fabricators Inc. machines metal parts for the automotive industry. Under the traditional manufacturing approach, the parts are machined through two processes: milling and finishing. Parts are produced in batch sizes of 90 parts. A part requires 3 minutes in milling and 8 minutes in finishing. The move time between the two operations for a complete batch is 9 minutes. Under the lean philosophy, the part is produced in a cell that includes both the milling and finishing operations. The operating time is unchanged; however, the batch size is reduced to 5 parts and the move time is eliminated. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional and lean manufacturing methods. If required, round percentages to one decimal place.

Jitsmsmart is a retailer of plastic action-figure toys. The action figures are purchased from Tacky Toys, Inc. and arrive in boxes of 48. Full boxes are stored on high shelves out of reach of customers. A small inventory is maintained on child-levels shelves. Depletion of the lower-shelf inventory signals the need to take down a box of action figures to replenish the inventory. A reorder card is then removed from the box and sent to Tacky Toys to authorize the replenishment of a container of action figures. The average demand rate for popular action figure, Agent 99, is 36 units per day. The total lead time (waiting plus processing) is 11 days. Jitsmart's safety stocky policy variables 0.25. What is the authorized stock level for Jitsmart?

In a large microelectronics plant, the assembly cell for circuitboards has a demand for 200 units an hour. Two feeder cellssupply parts A and B to the assembly cell (one A and one Bfor each board). Standard containers that look like dividedtrays are used. A container will hold 20 As or 10 Bs. It takes10 minutes to fill up a container with As and 20 minutes tofill up a container with Bs. Transit time to the assembly cell is5 minutes for both A and B. No safety factor is used. Set up akanban control system for the assembly process.

The avail-ability of processing per shift, after accounting for breaks anda mid-shift employee meeting, is 436 minutes. The currentoperating characteristics of each processing step are foundin the table below. Note that each step can only processone part at a time and all steps must process the same sizedbatches. a. Calculate the average processing time per unit and thecapacity at each step assuming batch sizes of:i. 10 unitsii. 20 unitsiii. 30 unitsiv. 40 unitsb. Identify the bottleneck operation and the line’s processingcapacity for each batch size listed in part a.c. Explain why batch sizes beyond 40 units will not increasethe line’s processing capacity further.
