a)
To determine: The number of Kanban containers required for a container size of 100 parts.
Introduction:
Lean systems in an organization have greater impact on the customers and their values. The goal of lean thinking is to improve the productivity of the department, and the goal for any lean system is to maximize the customer value.
a)
Explanation of Solution
Given information:
It is given that the plant would operate 2,000 hours per year, the demand rate is 100,000 units per year, and the circulation time is 24 hours.
Determine the number of Kanban containers needed for a container size of 100 parts:
It is calculated by dividing the multiple of demand and lead-time, and the container size. Standard container size is 100 parts and the demand rate is 100,000 units per year.
Determine the lead-time (T):
It is calculated by dividing the circulation time and the operating hours per year.
Determine the number of standard containers needed:
It is calculated by dividing the multiple of demand and lead-time, and the container size. Standard container size is 100 parts and the demand rate is 100,000 units per year.
Hence, the number of containers needed is 12.
b)
To determine: The effect of reducing container size from 100 parts to 60 parts.
Introduction:
Lean systems in an organization would have greater impact on the customers and their values. The goal of lean thinking is to improve the productivity of the department, and the goal for any lean system is to maximize the customer value.

Determine the lead-time (T):
It is calculated by dividing circulation time and the operating hours per year.
Determine the number of standard containers needed:
It is calculated by dividing the multiple of demand and lead-time, and the container size. Standard container size is 60 parts and the demand rate is 100,000 units per year.
Hence, the number of containers needed is 20.
c)
To determine: Process takt time.
Introduction:
Lean systems in an organization would have greater impact on the customers and their values. The goal of lean thinking is to improve the productivity of the department, and the goal for any lean system is to maximize the customer value.
c)
Explanation of Solution
Given information:
It is given that the plant would operate 2,000 hours per year, the demand rate is 100,000 units per year, and the circulation time is 24 hours.
Determine the process takt time:
It can be calculated by multiplying the minutes per hour with the operating time per hour and dividing it by the demand rate (D).
Hence, the process takt time is 1.2 minutes or 72 seconds.
c)
To determine: Process takt time if the demand is 80,000 units.
Introduction:
Lean systems in an organization would have greater impact on the customers and their values. The goal of lean thinking is to improve the productivity of the department, and the goal for any lean system is to maximize the customer value.
c)
Explanation of Solution
Given information:
It is given that the plant would operate 2,000 hours per year, the demand rate is 80,000 units per year, and the circulation time is 24 hours.
Determine the process takt time:
It can be calculated by multiplying the minutes per hour with the operating time per hour and dividing it by the demand rate (D).
Hence, the process takt time is 1.5 minutes or 90 seconds.

- For a particular operation, the setup time is 10 minutes and the run time is 50 minutes to produce a standard lot of 40 parts. It takes three additional hours to circulate a container of parts after production is completed. The demand rate is 20,000 parts per month. There are 160 production hours in a month.a. How many standard containers are needed?b. What is the takt time of this process?arrow_forwardCletus and Spike Company is implementing a Kanban system for a heated water bowl manufacturing line that produces 1,500 units in an eight-hour day. The heating element has a waiting time of 30 minutes and a processing time of one hour. The container size is 40 heating elements, and the safety factor is 15 percent. What is the maximum inventory of heating elements in the system?arrow_forwardExplain the following things related to lean: a) Don't get it, don’t make it and don’t send it b) Five golden rules of Gemba Management c) Jobs per hourarrow_forward
- Eakins Enterprises makes model boats, and it is switching to a lean manufacturing process. At one assembly area, Eakins is using one part container that holds 240 parts, and it wants the output to be approximately 80 finished parts per hour; they also desire a 20 percent safety stock for this part. How fast will the container have to make it through the system to accomplish this? Do not round intermediate calculations. Round your answer to two decimal places.arrow_forwardA JIT system uses kanban cards to authorize movement of incoming parts. In one portion of thesystem, a work center uses an average of 100 parts per hour while running. The manager hasassigned an inefficiency factor of .20 to the center. Standard containers are designed to hold sixdozen parts each. The cycle time for parts containers is about 105 minutes. How many containersare needed?arrow_forwardSandy is asked to produce 250 squidgets an hour. It takes30 minutes to receive the necessary material from the previous workstation. Each output container holds 25 squidgets.The factory currently works with a safety factor of 10%.How many kanbans should be circulating between Sandy’sprocess and the previous process?arrow_forward
