Soft Computing Evaluation Logic

3.1An Overview of the LSP Method

LSP is a decision method, and decisions are human mental processes performed by human perceptual computers. Consequently, the main credo of the LSP method is that the only right way to develop a decision method is by strictly following those logic patterns that are observable in intuitive human reasoning. To satisfy those goals, the LSP method follows the structure of SMER (Standard Model of Evaluation Reasoning), introduced in Section 2.2.1. The corresponding outline of the LSP method is shown in Fig. 3.1.1.

Figure 3.1.1 Main components of the LSP method.

The first step in the LSP method is to define the stakeholder and to specify the evaluation project based on stakeholder’s goals and interests. The second step is to develop a set of elementary suitability attributes, which contains all quantifiable inputs that affect the overall suitability of the evaluated object. The third step is to create for each elementary attribute an elementary criterion that specifies the suitability score as a degree of satisfaction of stakeholder’s requirements. Suitability scores are indicators between 0 (interpreted as no satisfaction) and 1, or 100% (interpreted as a complete satisfaction). Once we have n attribute suitability scores, it is necessary to aggregate them and generate an overall suitability score. So, in the fourth step of the LSP method we must ...
