PURPOSE:To extremely decrease the number of solution candidates and at the same time to facilitate program correction in response to the system change, by making use of the human experiential and theoretical knowledge to decide a planning order. CONSTITUTION:The superiority relation existing between processes of a production process plan is known to some extent by a human being owing to its conventional experiences. In this respect, the knowledges obtained by the experiences of human begins are described in a declarative language and stored in a system. Based on this storage contents, a production process plan is effectively decided. In other words, the number of solutions can be limited by means of the superiority relation obtained from experiences of human beings. Thus it is possible to prevent an extraordinarily large number of combinations of solutions produced by a linear planning method only. Furthermore the program correction is facilitated when the system is changed thanks to the description in a declarative language.
