1. Berwyn Manufacturing is starting to use a Kanban pull system to manage its parts inventory. At a given workstation, the planned daily usage of a particular part is 2100 parts per 10 -hour shift. The company operates one shift per day. Standard containers have a capacity of 45 parts, and it takes an average of 90 minutes for an empty container to be replenished and produced (circuit time). In addition, management has determined that the workstations have an inefficiency factor of 4%. 12 points a) Calculate the number of Kanban cards/containers needed to implement the pull system. If you calculate a number with a fractional value, round UP to the nearest integer value. Show your work below. 6 points (3/ error ) Note: Carry D \& T to at most 3 decimals. D= T= N=CDT(1+X) b) Now assume that it takes average of 50 minutes for an empty container to be replenished and produced. Calculate the number of Kanban cards/containers needed to implement the pull system. If you calculate a number with a fractional value, round UP to the nearest integer value. Show your work below. 6 points (-3/error) D= T= N=CDT(1+X)
