Problems solved by technology
However, there is no specific method for determining the fluctuation range of pipeline utilization, gas storage capacity, and gas consumption, no specific steps for calculating the weight of the evaluation index system, no specific calculation steps for calculating the weight index value of the evaluation index system, and no disclosure of gas transmission pipelines. The specific implementation steps of the comprehensive evaluation method for dispatching schemes, which is an incomplete and unrealizable technology
[0007] In the existing dispatching scheme evaluation method, the human influence factor is too large, and the evaluation result is not objective

Embodiment
[0268] Embodiment. This example is the method that carries out test in Sening Lan gas pipeline. Using the improved AHP analytic hierarchy process to specifically determine the weight value of the comprehensive evaluation index system of the gas pipeline dispatching scheme, and specifically determine the index values of the comprehensive evaluation index system of the dispatching scheme-gas pipeline flow, gas pipeline operation revenue, and pipeline peak-shaving capacity and operational risk evaluation indicators, and use the multi-level gray correlation method to comprehensively evaluate the scheduling scheme of the gas pipeline.
[0269] According to the actual situation of the Ning-Lan gas pipeline, considering the four criterion-level indicators of pipeline flow, operating income, operation risk, and peak-shaving capacity, the eight common working conditions of the Ning-Lan gas pipeline were evaluated, and the evaluation results See Table 1-3.

The invention relates to a comprehensive evaluation method of a gas pipeline scheduling scheme, which relates to the technical field of piping systems, and is characterized by adopting an improved analytic hierarchy process (AHP) to specifically determine the weight of the comprehensive evaluation index system of the gas pipeline scheduling scheme, and specifically determine the index values of the comprehensive evaluation index system of the gas pipeline scheduling scheme--gas pipeline flow, operation profit of gas pipeline, pipeline pitch peak capability and operational risk evaluation index, and a multilevel gray correlation method is used to comprehensively evaluate the gas pipeline scheduling scheme. The invention provides the comprehensive evaluation method of the gas pipeline scheduling scheme for guiding the production and operation of the gas pipeline, which is economical, reasonable and safe.
Description
technical field [0001] The invention is a comprehensive evaluation method for a gas transmission pipeline dispatching scheme. It relates to the technical field of piping systems. Background technique [0002] In recent years, around the multi-index comprehensive evaluation, relevant knowledge in other fields has been continuously integrated, which has enriched the multi-index comprehensive evaluation methods, and the research on this aspect has also continued to deepen. At present, there are dozens of comprehensive evaluation methods proposed at home and abroad, but generally they can be classified into two categories: the subjective weighting evaluation method and the objective weighting evaluation method. The former mostly adopts a qualitative method, and the weights are obtained by subjective judgments by experts based on experience, such as analytic hierarchy process, fuzzy comprehensive evaluation method, etc.; the latter determines the weights according to the relatio...
