Research On Production Process Management System Oriented To Hybrid Manufacturing Enterprises

The Hybrid Manufacturing Enterprise (HME) incorporates both continuous processes and discrete processes in an integrated way, with complex constraints during multiple production periods. The conflict, between complexity of production management and deficient management innovation, becomes increasingly fierce along with the development of a contemporary market which is mainly characterized by diverse demands, etc. The Production Process Management System Oriented to HME (PPMS-HME) was explored, based on the analysis of special characteristics and typical problems in the production processes in HME.A comprehensive functional framework for PPMS-HME was proposed, including a series of functional modules responsible for planning, organizing or controlling in each department while including the whole process. In order to reduce the coupling among layers, an agile Matrix System Architecture was designed. Consequently the system complexity was decreased and the average risks were radically lowered in developing and implementing the PPMS-HME.A HME-oriented hierarchy model for push-pull production planning and control was proposed. A Simplified Simulated Annealing Algorithm (SSA), based on heuristic rules such as production progress, and a Dynamic Scheduling Algorithm (DSA) were designed for efficient optimization of planning and scheduling respectively. The planning model adopted SSA to achieve optimized feasible master plans, MRP, etc., pulled by integrative production demands, with constrains of limited capacities and special rules at workshops, preplanning for both continuous and discrete processes according to the craft networks. The actual production processes were designed to be pushed by such approaches as process circulation card, etc. To advance efficiencies in neighbor workshops with the same type of capacities and special conditions, a shared capacities balancing model was proposed, symbolized as connected vessels in hydromechanics, and the scheduling rules and DSA were developed.The general, constructed and dynamic material transition mapping models were presented respectively, aiming at the diversity, e.g., material substitution and lot merging/splitting, in the HME. The simulated Hook technology in software engineering was employed for speedy compound mapping calculation, improving the information-integrating abilities of material tracking and tracing in complex materials transition processes in the HME.Based on the integrated extensive process information, an activity data mart, oriented to Activity-Based Management (ABM), was established using data processing approach such as defined activity transformation, and the tri-dimensional activity analysis model was further developed. Depending upon the different activity management demands, different activity categories can be chosen and the rational cost drivers can be measured to select the corresponding costing view. Therefore, costing information collection and cost accumulation can be realized as instant automated procedures, providing foundation data and technical support to implement advanced modern management approaches such as activity based management.A case study was conducted at an actual business, explaining the implement, application and effectiveness of PPMS-HME. This research helps the HME to adopt information technologies for management innovation, and is of theoretical and practical significance to the informationization in China.
