Modeling of combined discrete/continuous processes

摘要: The dynamic behavior of processing systems exhibits both continuous and significant discrete aspects. Process simulation is therefore a combined discrete/continuous problem. In addition, there critical need for declarative process modeling environment to encompass the entire range system operation, from purely batch. These issues are addressed by this article. A new formal mathematical description problem introduced enhance understanding fundamental changes required model systems. task decomposed into two distinct activities: physical behavior, external actions imposed on system. Both require components. Important contributions include powerful representation discontinuities in first detailed consideration how complex sequences control may be modeled general manner.
