Research on the Evaluation of Contingency Plan System of Emergency Management in Supply Chain: Based on Two-Tuple Linguistic Information

The emergency events on the supply chain may have adverse impact on the enterprises as well as the supply chain itself, which may also directly put threat on building up a harmonious society. As a result, a specific contingency plan for emergency management should be set up in order to deal with the emergency events. For the purpose of ensuring that the emergency events can be perfectly handled under the existing contingency plan. it is vital to make an accurate evaluation on the ability of the contingency plan to settle these events. This paper aims to set up the evaluation criteria for the contingency plan based on theoretical research and empirical study, and meanwhile. the contingency plan is assessed comprehensively by the two-tuple linguistic information model as well as IT-WAA operators. In addition, the effectiveness and practicability of the evaluation criteria and model are also verified through the empirical study.
