In the process of achieving enterprise value maximization, agricultural enterprises will face external and internal risks of uncertainty. The premise of risk control is to conduct a risk assessment. The key of risk assessment is to establish and optimize the evaluation index system. In this paper, we use factor analysis to optimize the evaluation index system of agricultural enterprises risk. The...
In order to explore relation between evaluation results from different methods, a new model is proposed to choose the optimal scheme based on set pair analysis though comparing the affiliation degree among the given schemes in this paper. Considering the discrepancy degree of evaluation results, it comes up with a method for selecting optimum from evaluation schemes, using the quantity of ranking...
Summary form only given. There is an extensive literature on decision-making under uncertainty. Unfortunately, up to day there are no valid decision principles. The widely used principle of maximization of expected utility has serious shortcomings. The first approach in classical theory of choice was formulated axiomatically in the expected utility theory of von Neumann and Morgenstern and is the...
This paper addresses the portfolio selection problem in a robust manner. In practice, it is difficult to collect all information to determine the precise bounds of the box uncertainty set used in robust portfolio optimization. To solve this problem, we introduce a novel uncertainty set: interval random uncertainty. We apply our interval random chance-constrained programming to robust semi-absolute...
