  Performance Data

    The following table summarizes the process performance data for the performance metrics identified in the Pizza Store Layout simulation.

    A learning curve is the relationship between a unit production time and the cumulative number of units produced (Ref. Chase, Jacobs and Aquilno). The Pizza production system is a just-in-time (JIT) system where Learning curves is important and can be applied as a trade-offs. The organization can use learning curve by changes in seating arrangements, equipment, and staff.   In this scenario, efficiency is key to customer satisfaction so the learning curve is used to measure the time it takes to service a customer and the total number of customers serviced. The process performance is based on the shortest average time for delivering the pizza to the customer from the time he orders it. The learning curve concept is based on the improvement in performance of process due to repetitive nature of tasks operated by an individual or an organization.
    One of the scenario variables was increasing the conveyor ovens which had a significant impact on waiting time for...
