Abstract
The inherent dangers of the petrochemical industry and the extreme meteorological conditions in the coastal areas make the island-type petrochemical parks have complicated safety hazards. In order to improve the safety management capability of my country’s island-type petrochemical parks, this paper analyzes the risk sources of the island-type petrochemical parks from the four subsystems of human, machine, environment and management, and uses the network analytic hierarchy process (ANP) to calculate the correlation weights between the indicators. The establishment of an evaluation model for the safety level of island-type petrochemical parks and quantitative analysis of the safety level of island-type petrochemical parks are of great significance for guiding the safety work of my country’s island-type petrochemical parks.
Highlights
The petrochemical industry is developing rapidly in China
Analytic Network Process is a decision-making method suitable for complex structures proposed by Professor T.L.Saaty in the 1990s
The traditional analytic hierarchy process (AHP) constructs a hierarchical structure, but does not consider the interrelationship between the indicators, while ANP considers the interdependence between the indicators on the basis of the analytic hierarchy process to determine the index weight More scientific and accurate
Summary
Analytic Network Process is a decision-making method suitable for complex structures proposed by Professor T.L.Saaty in the 1990s. It is a decision-making method developed gradually on the basis of analytic hierarchy process[10]. The traditional analytic hierarchy process (AHP) constructs a hierarchical structure, but does not consider the interrelationship between the indicators, while ANP considers the interdependence between the indicators on the basis of the analytic hierarchy process to determine the index weight More scientific and accurate. Network hierarchy analysis usually takes the following steps: constructing network hierarchy, constructing super matrix, constructing weighted super matrix, and calculating limit super matrix
