Supernetwork and entropy theory in quantitative decision-making of emergency logistics

Supernetwork theory is a newly tool which is used to study complex network. The quantitative decision-making of emergency logistics can be analyzed by the supernetwork definition which is defined by hypergraph. In order to adjust decisions and improve the overall efficiency, emergency logistics capability should be evaluated according to different stages in emergency logistics activities. Emergency logistics supernetwork model is built based on supernetwork theory, which is composed of three sub-networks, consisting of the organization, information and infrastructure. Four evaluation indicators relating to the emergency logistics supernetwork capability are analyzed, which include time effectiveness, quality, operation and supernetwork structure. Entropy evaluation model of emergency logistics supernetwork capability is built based on entropy theory and the definition of order degree. The methods are discussed for calculating the time effectiveness, quality, operation, supernetwork structure and total order degree. The practicability of the model is proved by the result of the numerical example given.
