System dynamics of process organization in the sphere of traffic safety assurance
Abstract The paper is devoted to studying trends in organization of traffic safety assurance systems in various countries. The materials in the paper focus on synthesis of management decision support systems in the sphere of traffic safety assurance. Structural and parametric identification of dynamic models for the level of traffic safety management in 8 countries (USA, Canada, England, France, Germany, Italy, Sweden, and Russia) is carried out. Calculation results are presented.
Abstract Making schedules for batch controlled plants in the chemical process industry is a topic often discussed. A wide range of scheduling tools have a separated model and a mathematical optimizer. In this paper we discuss a solution where a event discrete simulation tool is connected to the DCS. With all necessary model information stored in the DCS the scheduling tools in plant independent, where a optimizer (a combination of heuristics and genetic algorithms) generates a proposal for the final schedule.
