You are asked to analyze the kanban system of LeWin, aFrench manufacturer of gaming devices. One of the worksta-tions feeding the assembly line produces part M670N. Thedaily demand for M670N is 1,800 units. The average process-ing time per unit is 0.003 day. LeWin’s records show thatthe average container spends 1.05 days waiting at the feederworkstation. The container for M670N can hold 300 units.Twelve containers are authorized for the part. Recall that r isthe average processing time per container, not per individualpart.a. Find the value of the policy variable, a, that expresses theamount of implied safety stock in this system.b. Use the implied value of a from part (a) to determinethe required reduction in waiting time if one containerwas removed. Assume that all other parameters remainconstant.
