A company using a kanban system has an inefficient machine group. For example, the daily
demand for part L105A is 3,000 units. The average waiting time for a container of parts is 0.8
day. The processing time for a container of L105A is 0.2 day, and a container holds 280 units.
Currently, 29 containers are used for this item.What is the total planned inventory (WIP and
finished) for L105A?
8120 units
5400 units
5410 units
8102 units
The wheat harvesting season in the American Midwest is short, and farmers deliver their truckloads of wheat to a giant central storage bin within a 2-week span. Because of this, wheat-filled trucks waiting to unload and return to the fields have been known to back up for a block at the receiving bin. The central bin is owned cooperatively, and it is to every farmer's benefit to make the unloading/storage process as efficient as possible. The cost of grain deterioration caused by unloading delays and the cost of truck rental and idle driver time are significant concerns to the cooperative members. Although farmers have difficulty quantifying crop damage, it is easy to assign a waiting and unloading cost for truck and driver of $17 per hour. During the 2-week harvest season, the storage bin is open and operated 16 hours per day, 7 days per week, and can unload 34 trucks per hour according to a negative exponential distribution. Full trucks arrive all day long (during the…
