Production resource management using genetic algorithm

A computer program product, the computer program product being tangibly embodied on a non-transitory computer-readable storage medium and comprising instructions that, when executed by at least one processor, are configured to:

• schedule production events for each of a plurality of production resources used to manufacture one or more products relative to one or more time intervals while considering constraints related to product dependency trees for each of the one or more products and maintaining collaboration among the production resources, at least two of the production resources manufacturing and outputting a same product or same product component, wherein the instructions, when executed by the at least one processor, are further configured to:
• retrieve information related to each of the plurality of production resources,
• evaluate each production event for each product to determine a sequence of the production events for each of the plurality of production resources,
• generate a respective potential production scheduling scheme for use of each production resource within the one or more time intervals by:
• modelling each constraint as a production scheduling chromosome, and using a genetic algorithm handler to compare each of a plurality of production scheduling chromosomes relative to the constraints to select a subset of the production scheduling chromosomes to generate the respective potential production scheduling scheme for use of each production resource;
• generate a production schedule for the production events within the one or more time intervals based on the respective potential production scheduling schemes for use of each of the plurality of production resources within the one or more time intervals, wherein the production schedule includes a manufacturing schedule in which the one or more products are manufactured simultaneously and the component parts in each product are manufactured in sequence in the production resources;
• and
• manufacture the one or more products according to the production schedule for the production events at each of a plurality of production resources by minimizing a sum a transportation cost between the different production resources and a time cost of manufacturing the component parts in different production resources, the time cost including costs in time and capital related to switching production events and operations from a first component part to a second component part in one of the different production resources and costs related to assembling each product from the component parts.

A computer-implemented method, comprising:

• scheduling production events for each of a plurality of production resources used to manufacture one or more products relative to one or more time intervals while considering constraints related to product dependency trees for each of the one or more products and maintaining collaboration among the production resources by:
• retrieving information related to each of the plurality of production resources;
• evaluating each production event for each product to determine a sequence of the production events for each of the plurality of production resources;
• generating a respective potential production scheduling scheme for use of each production resource within the one or more time intervals by modelling each constraint as a production scheduling chromosome, using a genetic algorithm handler to compare each of a plurality of production scheduling chromosomes relative to the constraints and, based on the comparison, select a subset of the production scheduling chromosomes to generate the respective potential production scheduling scheme for use of each production resource;
• generating a production schedule for the production events within the one or more time intervals based on the respective potential production scheduling schemes for use of each production resource within the one or more time intervals, wherein the production schedule includes a manufacturing schedule in which the one or more products are manufactured simultaneously and the component parts in each product are manufactured in sequence in the production resources;
• and
• manufacturing the one or more products according to the production schedule for the production events at each of a plurality of production resources by minimizing a sum of and a transportation cost between the different production resources and a time cost of manufacturing the component parts in different production resources, the time cost including costs in time and capital related to switching production events and operations from a first component part to a second component part in one of the different production resources and costs related to assembling each product from the component parts.
