Embodiment Construction

[0079] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below taking a city gas pipeline system as an example. In particular, the specific examples described here are only used to explain the present invention, not to limit the present invention.

[0080] Step 1: Establish a system risk assessment index system.

[0081] Taking a city gas pipeline system as an example, the risk prediction index system of the city gas pipeline system is obtained through investigation and screening, and the risk influencing factor index system of the city gas pipeline system is as follows: figure 2 shown.

[0082] According to the index screening principle, establish the risk assessment index system of the system, as shown in the table below.

[0083]

[0084]

[0085] Step 2: Use rough set theory to assign index weights.

[0086] Since the calculation of the rough set weight assig...

Abstract

The invention discloses an urban gas pipeline system danger forecast and evaluation method. The method comprises the following steps: 1) establishing a system danger evaluation index system; 2) carrying out index weight assignment through a rough set theory; 3) carrying out system danger grading; and 4) carrying out system dynamic prediction and analysis. The method can solve the problem that, for the previous gas pipeline system danger evaluation methods, evaluation index weight assignment depends on subjective grading, and since the subjective grading has too many subjective views of an evaluator, the assignment result is not objective; the method can also solve the problem of the static evaluation method, and thus dynamic evaluation of the system is realized, and dynamic prediction of the system can be carried out; and the method is of great significance to safety management of gas pipelines, and meanwhile, provides important theoretical reference basis for the public safety management of a city.

Description

Technical field: [0001] The invention belongs to the field of evaluation methods for urban gas pipeline systems, and in particular relates to a risk prediction and evaluation method for urban gas pipeline systems. Background technique: [0002] The urban gas pipeline system is an important part of urban infrastructure, and its safe operation is related to the safety of people's lives and property, as well as the overall situation of social stability. With the continuous advancement of urbanization in our country, the living standards of urban residents are also constantly improving, and the application of city gas is becoming more and more extensive. The urban gas pipeline network is like the blood vessels of the human body. While it brings convenience to people's production and life, it is very easy to cause safety accidents due to its flammability, explosion and toxicity. In recent years, due to reasons such as overage service of the gas pipeline network, improper mainten...
