Abstract: Characteristics of customers special requirements for special steel products, and their influence on the traditional modularized product and process planning were analyzed. Based on Quality Function Deployment (QFD), a House of Quality (HoQ) model for incremental multi-process planning on variety customized requirements for special steel industry was established, under which the mappings between the customers special requirements and the engineering/quality characteristics were accomplished by utilizing hybrid reasoning method for special requirements on the basis of modularized design for regular requirements; and the comprehensive evaluation of the multi-process plans were given by using the weighted linear method. A waterfall decomposition method of HoQ was applied for customers special requirements converting into process chain planning, sequence planning and quality planning in turn; via which an incremental multi-process planning method for the dynamic production environments was realized and an effective quality control on product and process planning development was generated.
