A new method of trusted optimum measurement based on non-optimum analysis

According to the previous practice of optimization, kind of method has been developed to approach the optimum from non-optimum. It is considered that the non-optimum system does not exclude the targets and the results of optimum in practice. The formation of non-optimum serves as the basis for existence of optimum in uncertainty. Besides, the various characteristics and functions of the trusted optimum system can be measured from the maximum sub-optimum. By summing the practice, this paper has also come at maximum sub-optimum principle, established the conception of trusted optimum thresholds and put forward three theorems about trusted optimum parameters. Based on trusted optimum analysis, it puts out the new approach of system optimization. Meanwhile, it discusses about the general framework of trusted optimum.
