Pipeline Failure

Gas is a flammable, explosive and high-pressure medium. Gas pipelines are passing through many different geographical conditions of changing natural environment with gas. Therefore, a lot of adverse consequences will be bought by the gas pipeline failure, however not all consequences have a great impact on assessment of the losses. The rough set theory is used to simplify the accident loss. In this paper, the accident loss of gas pipelines of the gas enterprise in one city taken as an example is evaluated and forecasted with the rough set theory, which can bring the scientific foundation for the managers management and decision.

With the rising of the supply chain in all areas, trust issues become more and more concern. An applied-information technology with trust risk evaluation method is presented. Trust risk rating index system is built after analyzing trust risks in the supply chain. The key indexes of trust risk indexes are selected based on rough set theory, and a simplified trust risk evaluation index system is constituted. The weight of each index is calculated by rough set theory. Supply chain trust risk is assessed based on the determined index system, index weight and advantages of the uncertain multiple attribute decision making methods, which provide the basis for trust of supply chain risk prevention.
