摘　　要：The scheduling of by-product gases in by-product gas system,cogeneration system and production system is studied.All gas-consuming users are divided into three kinds according to their different characters and then a distribution model is built.A dynamic mixed integer linear programming（MILP）model for multiperiod optimization of by-product gas is performed to optimize by-product gas distribution to achieve total cost reduction.Case study shows that 6.2% operation cost is reduced by using the proposed model.The scheduling of by-product gases in by-product gas system,cogeneration system and production system is studied.All gas-consuming users are divided into three kinds according to their different characters and then a distribution model is built.A dynamic mixed integer linear programming（MILP）model for multiperiod optimization of by-product gas is performed to optimize by-product gas distribution to achieve total cost reduction.Case study shows that 6.2% operation cost is reduced by using the proposed model.
