Abstract: To improve the collaborative response efficiency of logistics business discovered through logistics information platforms and to optimize the design of the corresponding decision supportive modules, how to get the key information influencing decisions of logistics business trading parties is focused on. By constructing a logistics business collaborative response decision system, 17 potentially influential information factors such as knowledge level is identified from three aspects: decision makers, decision tasks and environment. The importance degree of each information factor is obtained by calculating their weights based on AHP, DEMATEL and AHP-DEMATEL methods. Moreover, the best order of the all information factors is determined according to the theory of the total orders and the important degrees above. Then, let the information with 85% cumulative weights as the key information, and all the key information data are derived from the intersection among the best order and the consensus key information under the three methods, which are marginal revenue, marginal cost, business matching degree, and so on. It may greatly reduce the design workload of logistics business control/decision-making system.
