A method of risk assessment based on GRA algorithm

摘要

The theory of Grey Relational Analysis (GRA) is a problem solving method for linear unbiased prediction in many areas. In this paper, a method of risk assessment for gas station was presented. According to the features of gas station management and operation, the safety assessment index for gas station was proposed. The index was evaluated the safety status of a gas station from the aspects of equipments, personnel, management, and surroundings. Furthermore the GRA algorithm of comprehensive appraisal of gas station security was founded. According to GRA algorithm, the evaluating method was validated by one gas station. The result showed that the gas station was relative safety.
