1. A production operation is a single-channel, single-phase, unlimited-queue-length queuing system. Products arrive at the operation at an average rate of 90 per hour, and the automated operation produces products at a constant rate of 95 products per hour. Engineering can modify the machinery at the operation to increase the production capacity to a constant rate of 105 products per hour. How much would the average lead time be reduced?
2. In Problem 1, how much would the average WIP be reduced with the improvement in lead time?
