Abstract: The system includes an ideal plan creation unit configured to create an ideal plan of the respective processes in a first process order based on a process knowledge information being a relationship between the product and an implementation time of the respective processes and on a predetermined indicator, a plan candidate planning unit configured to create a plurality of the plan candidates in the respective processes in an order opposite to the first process order based on a limitation condition being a limitation or condition which imposes on the respective processes, a plan candidate selection unit configured to calculate similarity between the ideal plan and each of the plurality of the plan candidates and to select the plan candidate having a high similarity to the ideal plan as an implementation plan, and a learning unit configured to reflect the selected implementation plan on the process knowledge information.
