System Dynamics Simulation Modeling and Heuristic Optimization of the Business Production Distribution System

System Dynamic Simulating Modeling is one of the most appropriate and successful scientific dynamics modeling methods of the complex, non - linear, natural, technical and organizational systems. The methodology of this method, together with use of digital computer, showed its efficiency in practice as very suitable means for solving the problems of management, of behavior, of sensibility, of flexibility of behavior dynamics of very complex systems. All this is made by computer simulating, i.e. “ in laboratory” , which mean without any danger for observed realities. System Dynamics simulation models of organizational business system of management of material (raw-materials, orders, money, labor, personnel, population, capital equipment: tools, units and factories e.t.c.) and informational flows in productive company will be presented in this paper. Organizational business-production system is simulated by effective scientific discipline System Dynamic and realized by Dynamo (PD4) and PowerSim program packages, also. Due to complexity and extensiveness of business management of organizational business process, or production-distribution system global simulation models of companies are presented on the modular way, i.e. with seven relevant sub systems: 1. Production-inventory sub system ; 2. Credits sub system ; 3. Debits sub system ; 4. Sub system of productive capacities ; 5. Sub system of Cash-Flow ; 6. Gross income-net income sub system ; 7. Sub system of demand for organization products, which are common structural characteristic in every productive business organization. These sub system are modeled according to its specific quality.
