介绍了管理学、决策论和信息学的一个新交叉研究领域——工程管理熵学，从它诞生的必要性、科学性出发，进而阐述其理论基础、方法与模型，特别介绍了复熵决策法、群决策熵模型和多因素耦合决策熵方法，最后给出的工程管理应用案例表明，所提出的熵模型能够有效地解决实际工程管理中的决策难题。

This paper describes the cross research field among management, decision theory and information science——engineering management entropy research. Firstly, the necessity and scientificity are discussed. Then its theoretical basis, methods and models are explained. Especially, the complex entropy decision making method, group decision making entropy model and multivariate coupled decision-making entropy method are described. Finally, the engineering management application cases are given, which prove that the proposed engineering management decision model based on entropy can effectively solve some key decision-making problems in practical engineering management.
