Multi-Criteria Decision Making (MCDM) is a widely used method in decision science. Group Decision Making (GDM) helps to fuse the judgments of individual decision makers (DMs) through MCDM to reach better decision. This study presents a decision fusion model based on AHP and fuzzy integral to possess both advantages of MCDM and GDM. Each DM uses hierarchical AHP structure to separately obtain the evaluations of alternatives. In addition, the evaluations of DMs can be integrated by fuzzy integral through nonlinear combination. Supply chain management strategy is used to illustrate the proposed model, which demonstrates the feasibility of this model. From the demonstrative example, the group decision process demands shorter time and avoids tedious group meetings. The nonlinear fusion function performs better than average method especially for extreme preference.
