Chapter 16, Problem 3P
Summary Introduction
To draw: To compute the number of kanbans required for the circuit board during the assembly process.
Introduction
Lean production is a system for the management in which it focuses on reducing waste, checking the quality, and all the efforts are put to fulfill the market needs. All the activities starting from manufacturing to distribution are managed efficiently through the lean system.

An assembly station is asked to process 100 circuit boards per hour. It takes 20 minutes to receive the necessary com- ponents from the previous workstation. Completed circuit boards are placed in a rack that will hold 10 boards. The rack must be full before it is sent on to the next worksta- tion. If the factory uses a safety factor of 10%, how many kanbans are needed for the circuit board assembly process?
An assembly station is asked to process 100 circuit boards per hour. It takes 20 minutes to receive the necessary components from the previous workstation. Completed circuit boards are placed in a rack that will hold 10 boards. The rack must be full before it is sent on to the next workstation. If the factory uses a safety factor of 10%, how many kanbans would be needed in each case? (Round answers to 0 decimal places, e.g. 25.)
a. Demand is increased to 200 circuit boards per hour. How many kanbans?
b. The lead time for components is increased to 30 minutes. How many kanbans?
c. The rack size is halved. How many kanbans?
d. The safety factor is increased to 20%. How many kanbans?
The welding department supplies parts to the final assembly line. Management decides to implement a kanban system and has collected the following data:
The daily demand is 2000 units.
The production lead time is 4 days (this includes processing time, transport time, and waiting time).
Management has decided to have 1 day of safety stock.
One container fits 400 units.
How many kanban containers will be needed to support this system?
