[0089] According to the above model and the corresponding solution method, the optimal x i and f i :

[0090] Table 1 Optimization result chart

[0091]

[0092] Substitute the parameter values ​​obtained from the planning model into the system dynamics model, and use VENSIM software for simulation. The data start from 2006, with year as the unit, a total of 15 years. See the main results Figure 3-8 :

[0093] These plots show the main results we want to investigate:

[0094] (1) Due to our scientific optimization technology, the natural gas industry has had a great improvement in economic growth and profit. exist image 3 Among them, it can be seen that the total value of the natural gas industry in 2010 will reach 19 billion yuan, which is 50% higher than that in 2006. By 2020, this figure will reach 60 billion yuan.

[0095] (2) Acetic acid products and butyrolactone are the most important developments. Depend on Figure 4-6 , these products have developed a ...

The method comprises the steps of (A) determining the product types included in the gas industry and corresponding weights, (B) setting a rough variable in the gas industry, (C) constructing a gas industry rough multi-objective programming model, (D) using a rough expectation operator to process the model, and (E) solving the model. The system and the method are suitable for the gas industry planning.

Description

technical field [0001] The invention belongs to the technical field of oil and gas reservoir development engineering management, specifically a method for simulating and optimizing a natural gas industry system in a rough environment, and relates to the establishment, simulation and solution of a regional natural gas industry dynamic programming model. Background technique [0002] At present, research related to natural gas mainly focuses on the use of new technologies, while research on the natural gas industry chain and its economic benefits is rarely involved. Natural gas industry planning is a complex decision-making problem involving different standard dynamic situations. If it is not scientifically simulated and optimized, it may cause wrong decision-making, resulting in huge economic losses. [0003] The invention is aimed at the planning of the natural gas industry in the Yangtze River Basin, and the natural gas is the raw material of chemical products. Identify m...
