In order to make the profitability evaluation of the listed companies more effectively, and provide a basis for decision-making, profitability evaluation model was established in this paper based on particle swarm algorithm (PSO) and the back-propagation algorithm (BP). Then the case study of profitability evaluation of power listed companies in China is proposed. The model takes advantages of the...
The transportation volume of hazardous material is increasing, and the potential risk of hazardous material for environment and mankind is enlarging. How to select the best transportation route, insure transportation safety and reach destination rapidly is an important problem for decision department. The transportation route decision-making method of hazardous material is put forward in this paper...
The concept and characteristics of the ecotype supply chain are discussed in the paper firstly, and then a further improvement of performance evaluation index system of ecotype supply chain is made. Based on the above discussion, a fuzzy BP neural network evaluation method which optimized by PSO is established. Through an example, the proposed method is used to evaluate the performance of an ecotype...
