Abstract
Various systems that support the production planning by such as an automatic generation systems of the assembly procedure and the best scheduling are developed. However, it is difficult to say to support the entire production planning integrated. So, the integration of a variety of information processing in the planning is expected. Information on the production plan is not generated at a certain stage alone at a time, and planner has to generate information phased and growing up by changing his view of a plan from global aspect to local aspect.
In this research, the authors paid attention to a phased information processing of the production planning, and consider the management of job information to integrate the each planning level. The network model of information is applied as an integrated model to manage a phased generating and processing of job information. The composition (has-a) relation between an upper layer job and relation and a lower layer ones is proposed in this model and integrated management of various hierarchies of the production planning is proposed by describing the job model and the relational model of job positively.
