Abstract: In this paper, in order to realize the allotment of the gas consumption of natural gas users rationally, the natural gas resources coordination and optimization model was established and solved by replacing the natural gas price with its utilization value, with the benefit maximization as the objective function and the gas consumption as the constraints. Without the deficiency of traditional methods which have bigger errors in gas allotment, this model has helped to realize coordinated and optimized allotment of natural gas resources, thereby increasing utilization value of natural gas. This model plays an instructive role for natural gas marketing departments to prepare gas consumption schemes, gas supply plans and emergency plans rationally for purpose of optimization, coordination and scheduling decision of natural gas resources.
