Abstract
System Dynamics Analysis of Integrated Pipeline Corridor Based on Risk Loops
Highlights
As a public tunnel for the centralized laying of municipal utility pipelines, integrated pipeline corridors can effectively solve many urban problems such as repeated road excavation and environmental deterioration caused by traditional pipeline laying and greatly improve the urban living environment
Method and the principle of pairwise comparison in the analytic hierarchy process (AHP), we determine the interaction and the strength of the relationship between the risks of integrated pipeline corridor operation and maintenance, construct a dynamic risk model based on system dynamics, and analyze the influence mechanism of the risk control input on the system risk in integrated pipeline corridor operation and maintenance management
Qualitative risk assessment is carried out based on the index system of expert judgment and is potentially subjective. Methods such as the analytic hierarchy process [4], fuzzy comprehensive judgment [5], and gray correlation analysis [6] are widely used in integrated pipeline corridor operation and maintenance risk assessment, which makes the determination of index weights and index assignment more scientific and objective
Summary
As a public tunnel for the centralized laying of municipal utility pipelines, integrated pipeline corridors can effectively solve many urban problems such as repeated road excavation and environmental deterioration caused by traditional pipeline laying and greatly improve the urban living environment. Qualitative risk assessment is carried out based on the index system of expert judgment and is potentially subjective Methods such as the analytic hierarchy process [4], fuzzy comprehensive judgment [5], and gray correlation analysis [6] are widely used in integrated pipeline corridor operation and maintenance risk assessment, which makes the determination of index weights and index assignment more scientific and objective. The quantitative risk assessment is mainly based on the physical model and calculation methods related to the integrated pipeline corridor, focusing on the quantitative risk assessment of the fire accident characteristics that have the greatest impact on the integrated pipeline corridor operation and maintenance risks. We get 5 types of Class I risks and types of Class II risks as presented in Tab. 1
