Application of Possibility and Satisfiability Concepts in Multi-Objective Desicion-Making

In this paper the concepts of 'possibility' and 'satistiability'are intro-duced together with their calculations. These concepts are the quantitative descriptions of ideas of the 'demand' and 'possible'. Whenever it is expected not only to satisfy 'demand',but also to be 'possible' in practice, the application of possibility and satisfiabilityconcepts is sure to be useful. Numerical examples and brief discussions are given.
