| Abstract: | Some conditions and some properties of state variable weights are discussed. It is proved that the set of state variable weight is semi-group on addition, maximum, minimum and the Hadarmard product respectively. Some methods of constructing new state variable weights are given based on the results. The equivalence of constructed state variable weights and the original state variable weights are studied. |

| Keywords: | Multi-factor synthesis decision-making state variable weights semi-group the equivalence of state variable weights |
