Petri Nets based Framework of Process Industries for Energy Saving Production

Petri Nets are powerful simulation tool for process industries, based on theories of Petri Nets, this paper structured the framework of process industries. Quantitative and qualitative relationships between production and energy consumption system and Information system are surveyed. According to production and energy consumption model, enterprises integrated Petri Nets framework are divided into linear and nonlinear models. Due to parameter of scheduling or optimization time, the integrated model furthermore were assigned as constraints depend on time and in-depend on time, and energy saving production optimization algorithms library were proposed. Finally, the approach is proved by an engineering example.
