Method and system for analyzing throughput
First Claim
1. A throughput analysis method for a manufacturing line including a plurality of machines, each configured to generate event codes which are input to the throughput analysis, the throughput analysis method comprising:
- calculating a first throughput value for the plurality of machines based on the input;
ranking the plurality of machines and their associated event codes according to their effect on throughput;
altering a value of a first event code associated with a first machine to generate an altered first event code for a new event code input;
recalculating a second throughput value based on the new event code input; and
comparing the first throughput value with the second throughput value to generate a weight of the first event code on the first throughput value.

Abstract
Described is a method and system for analyzing throughput of a production line. The method includes selecting among the stations, a set of susceptible stations that are affected by at least one selected event, ranking the susceptible stations with respect to a selected event and the predetermined criteria to determine an ordered list of more susceptible stations, altering the selected events to generate a new set of events, reranking the susceptible stations with respect to the selected events comprising the new event to determine a new ordered list of more susceptible stations and determining the most susceptible station based on a comparison criterion of the original ordered list of more susceptible stations and the new ordered list of more susceptible stations.
