6. Work centers A and B are connected along a manufacturing flow line where A is the upstream and B is the downstream work center. Demand for B is 2,000 units per day. It also needs 10% extra units as a safety policy to handle the random jumps of demand in further downstream work centers. Kanban cycle time from B to A and back to B with a standard container of 22 units is approximately 0.1 day. A) Compute the number of kanban between these two work centers. B) What is the total number of kanban circulations per day from B to A (and return to B)? C) What is the maximum possible level of inventory at work center B? 6.
