Question

Anna works on an assembly line where it takes her 20 minutes to produce 150 units of a product needed to fill a container. It takes her an additional 5 minutes to transport the container to Josh, who works at the next station. The company uses a safety stock of 20%. The current assembly line uses 5 kanbans between Anna’s and Josh’s stations. What is the demand for the product? Calculate the answer in units per minute. Calculate in Excel and round down to the nearest whole number.

Answer 1

Hence the demand for the product D = 25 units per min.

Step-by-step explanation:

Units produced (C) = 150

Time for production = 20 min

Time for transport = 5 min

Total time (T) = 20 + 5 = 25 min

Safety stock (S) = 20%

Number of Kanban (y) = 5

Demand unit per min = D

`y = D*T*(1+x)/C\\5 = D*25*(1+0.2)/150\\30 = D*1.2\\D = 30/12*10`

D= 25 units per min.
