Abstract: To provide a more efficient resource allocation method and system using a genetic algorithm (GA). The present technology includes a method for allocating resources to a production process including a plurality of processes, the method including allocating priorities to the plurality of processes, selecting processes executable at a first time among the plurality of processes and capable of allocating necessary resources, allocating the necessary resources to the selected processes in descending order of priorities, selecting processes executable at a second time that is later than the first time among the plurality of processes and capable of allocating necessary resources, and allocating the necessary resources to the selected processes in descending order of priorities. The present technology also includes, as a method of expressing genes of GA, not having direct allocation information for genes but having information (priority) for determining an order for allocation.
