The Hybrid Manufacturing Enterprise (HME) incorporates both continuous processes and discrete processes in an integrated way, with more complex constraints among the production periods. The conflict, between the complexity of production management and the deficient management innovation, becomes increasingly fierce along with the development of contemporary market that is chracterized by diverse demands, etc. The Production Process Management System Oriented to HME (PPMS-HME) was researched, according to the analysis of special characteristics and typical problems in the production processes in HME.6 d; U1 `: `6 _/ L# z
A comprehensive functional framework for the PPMS-HME was proposed, including a series of functional modules which were responsibile for planning, organizing or control in each department and the whole process. An agile Matrix System Architecture was designed, to reduce the coupling among layers. The system complexity was decreased and the average risks were radically lower in developing and implementing the PPMS-HME.9 l9 W, g) e( A) V
A HME-oriented hierarchy push-pull production planning and control model 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 continue and discrete processes according to the craft networks. The actucl 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.

Y# y4 x& WThe general, constructed and dynamic material transition mapping models were presented respectively, aiming at the diversity, e.g. material substitution, 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.
% g8 \6 r a" @- ]0 b2 }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 furtherly 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 supporting to implement advanced modern management approaches such as acitivity based management. ` s8 e( F! l1 g
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. + h4 q9 ?: j2 Y* i$ S: t& L7 q
