The optimal linear assignment method for multiple attribute decision making

The multiple attribute decision making method is an active area of research. We arrange schemes in simple order based on the positive and negative ideal schemes. Then we synthesize all indexes and seek the schemes' sequencing frequency. When it is difficult to give schemes' total sequencing, we turn it into an optimal linear assignment model. So we can optimize the schemes. At the same time, we provide another reliable and feasible method for the multiple attribute decision problem.
