Aiming　at　the　decision-making　problem　in　heterogeneous　information　environment　and　considering　the　influence　of　decision　makers’　psychological　behavior　on　decision-making　results,　this　paper　proposes　a　multi-attribute　decision-making　method　based　on　prospect　theory　in　heterogeneous　information　environment.　The　heterogeneous　information　in　this　paper　indicates　that　the　decision　attribute　value　is　represented　by　various　types　of　data　forms,　including　exact　number,　interval　number,　linguistic　term,　intuitionistic　fuzzy　number,　interval　intuitionistic　fuzzy　number,　neutrosophic　numbers,　and　trapezoidal　fuzzy　neutrosophic　numbers,　and　so　on.　Firstly,　the　distance　and　similarity　measure　of　various　heterogeneous　data　are　introduced,　and　the　heterogeneous　information　attribute　weights　are　obtained　using　the　deviation　maximization　method.　Then,　the　psychological　expectation　value　of　each　attribute　given　by　the　decision　maker　is　used　as　a　reference　point,　thereby　calculating　the　gain　and　loss　of　each　attribute　value　relative　to　the　reference　point,　and　establishing　a　gain　matrix　and　a　loss　matrix.　On　this　basis,　the　prospect　theory　is　used　to　obtain　the　comprehensive　prospect　value　of　each　alternative,　so　as　to　obtain　the　alternative　ordering　result　and　optimal　alternative.　Finally,　an　illustrative　example　about　typhoon　disaster　assessment　is　presented　to　show　the　feasibility　and　effectiveness　of　the　proposed　method,　and　the　advantages　of　the　proposed　method　are　illustrated　by　comparison　with　other　methods.　©　2019　The　Authors.
