ABSTRACT:
An improved system and method for scheduling a plurality of orders into a factory for processing by one or more of a plurality of machines located therein, based on the use of a Continuity Index job release strategy. The system and method is particularly addressed to the enhancement of such a job release strategy by introduction of Factory Profile and priority criteria and an algorithm for automatic determination of an optimum job release point based on such criteria. The scheduling methodology is characterized by defining a Continuity Index (CI) for each of the jobs as the ratio of the actual time the job is being processed by such one or more machines to the total time from release of the jobs into a shop wherein such machines are located until the completion of the job, establishing a Factory Profile curve of optimum CI value over time, determining a curve of actual CI for each of the jobs being tested for release beginning from a trial start date and extending through the expected completion of the job, comparing the actual CI curve for each of such jobs with the Factory Profile optimum CI curve and accepting the job for processing by the shop on the trial start date if the actual CI curve closely follows the Factory Profile curve throughout the processing time for the job, and otherwise determining a new curve of actual CI for the job from a new trial start date and repeating the comparison.
