Clustering analysis is usually used to extract the time points in order to give a reasonable divisions of intersection traffic signal time intervals. However, in consideration that the volume is similar while the direction is different or similar cycle while different green ratio, the timing of the signal will be divided into different time periods. In this paper, a two-dimensional clustering analysis...
There are a lot benefits to enable intelligent agent understanding the information from semantic Web. It enhances the efficiency of information usage and at the same time, suffices the need of users. Semantic documents contain adequate semantic information which helps understanding. However, discrepancy between ontology which is an interpreter of semantic document prevents the share of knowledge....
The aim of virtual enterprise which is composed by a number of member enterprises is to gain its benefit, but how to distribute the benefit may impact its stability. The traditional Shapley value method only takes into account the important extent of member enterprises in virtual enterprise, in the actual operation it has some defects. In order to enhance the stability of virtual enterprise, in accordance...
With aggravating of market competition, the operation of supply chain coordination becomes more and more important. Therefore this paper firstly describes the capability and profit of supply chain members and the operation of supply chain coordination using multiple-objective programming and proposes a multi-product, multi-stage supply chain coordination model based on VMI ,which comprises one manufacturer...
The unfair interest distribution of virtual enterprises will cause their members' loss of trust in the justice of interest distribution, lead to the disharmony among the members of virtual enterprises, and result in conflict and confrontation during cooperation. Based on HeXie management theory, the HeXie mechanism is established from the angel of justice so as to settle the problem of unfair interest...
By utilizing the exterior resources, the virtual enterprise is an important organizational model to obtain competitive advantage and achieve rapid growth. Trust is one of the critical success factors of virtual enterprise, and success in virtual enterprise id heavily dependent on establishing and maintaining trust. This paper used HEXIE management theory, established virtual enterprise trust management...
Loan risk is one of most important source of risk that our commercial bank face and it constructs the main part of risk management. So strengthening the measurement is of much significance to our commercial bank. Based on brief introduction of the theory of loan projects risk, considering the complexity of multi-objective decision of credit risk assessment in commercial bank, this paper builds a new...
This paper proposes a cooperation mechanism among seller agents and builds a model based on multi-agent system. In the model, a manger agent has been set to watch activities of other agents. It will encourage the cooperative sellers and punish the non-cooperative seller agents by adjust the sellerpsilas reputation in the repository. With this mechanism, a seller would complete the trade with the buyer...
The principle advantage and shortcoming of quantum clustering algorithm (QC) is analyzed. Based on its shortcomings, an improved algorithm - exponent distance-based quantum clustering algorithm (EQDC) is produced. It improved the iterative procedure of QC algorithm and used exponent distance formula to measure the distance between data points and the cluster centers. Experimental results demonstrate...
Cementing quality directly influences exploitation of oil or gas layers in oil or water boreholes. Characteristic wave (or pseudo-Rayleigh wave) in acoustic full waveform can evaluate the cementing quality of the secondary interface in cased boreholes. Before evaluating the cementing quality of secondary interface, we must analyze bath propagation velocity and amplitude of the characteristic wave...
