relative chance
2.Abstract: Through building the appraisal model of investment chance and relative appraisal index, the best investment chan ce could be chosen by systematic analysis scientifically and objectively, so as to avoid blind investment and ensure the development of national economy and the interests of investors.
3.According to management and behavior theory, the concept of base efficiency is established. Referring to P, N programming, two fuzzy chance constrained DEA models based on P, N measure, FCCPDEA, FCCNDEA are proposed, which handle fuzzy uncertainty with confidence level and identify the efficient decision making units with efficiency discriminator, and reach the conclusion that at least one DMU (decision making unit) is efficient relative to its base efficiency with a certain confidence level.
