The ranking of interval numbers is an important research topic for undecided multiple-criteria decision-making (MCDM) problems. This paper mainly focuses on the problem that different interval numbers have the same possibility degree values in MCDM with interval numbers. First, we propose three compatibility relations theory models corresponding to different risk preferences type decision-makers to...
Based on the former researches by minimum method on the impacts of the ecological impact factors (water depth, water temperature, substrate, et al) on suitability indices of adult fish growth, spawning and hatch, we calculate the habitat suitability indices by the parallel method, and use different simulation equations (polynomial equation, exponential equation, logistic equation, et al) to compare...
Poly (ethylene terephthalate) (PET), the most important specie of thermoplastic polyester, have been widely used in humans' life. Waste PET is not easy to degradation and become a burden for the environment; therefore, its recycling is very important. High surface area activated carbon is prepared by chemical activation using waste PET. The experiment condition are as follows: carbonization temperature...
This paper presents a new economic approach for studying competition and innovation in a complex and highly interactive system of network providers, users, and suppliers of digital goods and services (i.e., service providers). It employs Cournot and Bertrand games to model competition among service providers and network providers, respectively, and develops a novel unified model to capture the interaction...
DNA algorithms have solved some NP-complete problems such as Hamilton path and Chinese postman problem; however there are only some suggestions for the shortest path problem. Weight encoding is a very important and challenge aspect in DNA computing. In this paper a computing method which based on incomplete Molecule Commixed Encoding (IMCE) is proposed. In this method, the vertex of the graph is encoded...
A simple fuel economy operating mode and a comprehensive fuel economy operating mode of tractor equipped with CVT are proposed in this paper. The former takes the minimum fuel consumption rate point in the whole engine operating range as the target, the throttle opening keeps constant, the gear ratio of CVT is adjusted by the controller which is a single parameter control system. The later takes the...
This paper analyzes the main factors impacting electricity intensity (namely power consumption per unit GDP) in China first, which include power price, gross domestic product and the proportion of industry in whole economy. Then the relationships between power price and electricity intensity was studied based on Granger-causality and cointegration tests. The result indicates that there exists Granger...
It is only an order quantity which is decided for a spot selling time in the previous supply chain contract with options. However, the effect of the lead-time on the supply chain is indispensable. This paper considers the options contract with the time-based parameters on the background of food supply chain in which the model analyze that the contract parameters and accuracy of forecasting demand...
