Batch chemical process is typical and complicated hybrid production process where discrete variable and continuous variable coexist. Traditional scheduling research ignores or simplifies the practical factors, so it can't accurately direct the production practice. The project will research basic theories, methods and technologies of batch chemical process production scheduling under true environment where uncertainty is taken into account. It will break out the research bottleneck when uncertain factors and robustness are both considered. The affect laws of different uncertain factors to production time, production scheduling and production system will be revealed, and the production time model will be built to unify and simplify all kinds of uncertain factors. Multistage uncertainty scheduling strategies which includes robust scheduling, scheduling rectification and scheduling compensation will be put forward. Scheduling expectation model, batch process scheduling and stochastic programming compensation model will be built, and several new scheduling algorithms matching above models will also be designed. The uncertain factors processing methods will be studied, and scheduling rectification rule base and scheduling rectification trigger mechanism will be designed. The multi-objective evaluation based on fuzzy measure and fuzzy integral will be put forward. The uncertainty scheduling platform will be designed and the simulation system will be constructed in order to actualize uncertainty simulation and scheduling validation. The research results will offer the effective methods for batch chemical process production management and improve the chemical industry competitiveness.
