Exam 9: Lean Systems

Lady Bug Machineries uses a lean production assembly line to make its generators. In one assembly area, the demand is 200 parts per 8-hour day. It uses a container that holds 10 parts. It typically takes about 5 hours to round-trip a container from one work center to the next and back again. They also desire to hold a 20% safety stock of this part in the system. -How many containers should the lean system be using?

Copenhagen Industries uses a kanban system to manage production of their subassembly. In a 10-hour day, they use 1,500 units and use containers that can hold 50 units each. It takes 45 minutes to fill and move a container of parts to the right place on the subassembly line that is currently rated at a 15% safety factor. -If the required safety stock was changed to zero and 3 containers were being used in the system, calculate the maximum inventory.

The Frankenmuth Fasteners Co. was implementing lean throughout their shop floor and needed to determine the number of containers at several of their work centers. In one such work center, the demand was 200 parts per hour, and the containers they used for this part held 50 parts. It normally takes 6 hours for a full container to make a circuit through the work cell and back to its input side, and they desired to carry 12% safety stock in the system. -How many containers should the lean system be using?

A lean system has the following characteristics: demand rate = 40 parts per hour; safety stock required = 10%; the container size = 8; lead time to replenish an order = 4 hours. -If the number of containers is decreased by 2 units, what would be the new required safety stock, all else being constant?

An integrated electronic-chip manufacturer has a demand for a specific component of 800 parts per 8-hour day. The manufacturer wants to design a lean system using containers. The containers the manufacturer used for this component held 20 parts. It takes about 4 hours to round-trip a container from one work center to the next and back again. The manufacturer also wants to hold 10% of safety stock of this part in its system. -Calculate the maximum system inventory for this part.
