Abstract
Computation is made of a production plan and sequence satisfying constraint conditions using an interaction model. A system includes a storage device to store management information about specifications on each of a plurality of things to be produced and a computational device to compute a planned sequence of things to be produced in a production process to produce the plurality of things using an interaction model, based on the management information. In this system, the computational device computes an interaction model in which an assignment event of a sequential position in a production process to each of the things is assumed as a variable and a constraint condition regarding the production process is set as strength of an interaction between variables.
