With the growing worldwide awareness of environmental protection and sustainable development, green purchasing has become an important issue for companies to gain environmental and developmental sustainability. Thermal power is the main power generation form in China, and the green supplier selection is essential to the smooth and sustainable construction of thermal power plants. Therefore, sel...

The study aims to avoid the phenomenon that thousand cities seem same in construction of smart and efforts all walks life are jointed implement creation city brands. First, basic theory is introduced. Second, restricting promoting factors influencing development analyzes, evaluation system established. Then, model for based on neural network implemented. Finally, some domestic selected as datas...

The location of logistics nodes that facilitate the China Railway Express (CRexpress) and rail-sea intermodal transportation has received increasing attention in under Belt Road initiative. This paper selects 38 cities as candidate Chinese international container hubs (CICIHs) through qualitative screening by considering current operations CRexpress/rail-sea government planning strategies. Subs...

The grey systems theory aims at the objects that their information is inadequate and this situation is general in reality. It has been urgent work to study the uncertain problems using the missing information. With the help of the simple introduction of grey systems theory, we further study the covered operation and get some calculation rules about grey number. The definition of grey matrix (GM...

When huge disasters strike, the afflicted areas need help from all sides. However, it is difficult for relevant departments to quickly obtain relief needs of disaster and accurately distribute materials on demand. To solve this problem, paper proposes a demands urgency evaluation approach which integrates Natural Language Processing (NLP), Analytic Hierarchy Process (AHP), EWM (the entropy weig...

Supplier selection is a multi-criterion decision making problem under uncertain environments. Hence, it is reasonable to hand the problem in fuzzy sets theory (FST) and Dempster Shafer theory of evidence (DST). In this paper, a new MCDM methodology, using FST and DST, based on the main idea of the technique for order preference by similarity to an ideal solution (TOPSIS), is developed to deal w...

Energy efficiency evaluation of industrial park customers is carried out to help develop optimization strategies and improve the energy level. The indexes are proposed based on pressure-state-response (PSR) model redundant selected by combining principal component analysis (PCA) correlation analysis. Thus dynamic index system constructed. weight calculated entropy method (EWM). An improved Grey...

Accurate prediction of the future electricity consumption is crucial for production electricity management. Since the storage of electrical energy is very difficult, reliable and accurate prediction of power consumption is important. Different approaches for this purpose were used. In this paper, Grey model (1,1) based on grey system theory has been used for forecasting results. Annual electric...

rapid technological and economic growth over the last several decades has changed human lives and made modern society face complex decision making problems. these kinds of problems are characterized by incommensurate and conflicting criteria or objectives such as cost, reliability, performance, safety and productivity. multi criteria decision making is an approach that can be used to deal compl...
