Metro systems are playing an increasing role in modern cities, and various management solutions are proposed to improve their efficiency. When analyzing the effects of those solutions, simulation proves to be an effective and cost-saving method. This paper presents an effective simulation model for multi-line metro systems based on the OD (origin-destination) data and the network connection data....
Considering the development situation of each object in different time interval in the dynamic evaluation problem, we provide a method with the feature of reward and punishment. In this method, the evaluation information participates in evaluation in the form of a whole vector. Then the timing weights are determined by the TOPSIS method, which can express the purpose of reward and punishment. Based...
The most common method of tender evaluation for engineering projects was traditional comprehensive scoring or the lowest tender price method after evaluation, and AHP or fuzzy comprehensive judgment was also used for tender evaluation, but all these methods had several defects such as having highly subjectivity, lacking analysis of evaluation indexes and not reflecting weaknesses of tenders and causes...
According to the characters of the third-party logistics enterprise, the article constructs an index system of performance evaluation that consists of four classification criteria which includes the financial performance, operational procedures, learning and innovation and customer relationship management. The index weights are determined by combining analytic hierarchy process (AHP) method and principal...
The most common method of tender evaluation for engineering projects was traditional comprehensive scoring, and analytic hierarchy process or fuzzy comprehensive judgment was also used for tender evaluation, but all these methods had the defect of having highly subjectivity. Although the traditional DEA model can exclude bias caused by human factors, it can't distinguish efficient decision-making...
Referring to administrative decision-making systems and procedures in developed countries, this paper proposes an improved model of administrative decision-making support system based on MAS, which emphasizes the effect of consulting and monitoring subsystems on administrative decision-making, to overcome the deficiency of present decision-making support system. Specifically, the framework of this...
The Grid offers new opportunities and raises new challenges for data integration. The Grid communities have paid great attention to data integration middle ware in grid environment. But few of those projects actually establish semantic connections among heterogeneous data sources. Recently, several resolutions of data integration in grid environment have been proposed. However most of them put their...
The administrative decision-making is very important for the government. However, the decision-making procedure of the government was low-efficiency in the past. Based on the multi-agent technology, an administrative decision-making support system is proposed in this study, which improves the decision-making effectiveness and efficiency through the distributed collaboration of different decision-making...
The functional orientations provide a guide for the construction of governmental informationalization in China. Based on the scope of organizational boundaries and the direction of information flow, the functional orientations of governmental informationalization in China are divided into four kinds of important types: e-procurement, the integration of governmental information resources, the open...
Along with rapid development of workflow technology, on the market, there are a lot of workflow products. Workflow exception handling study in the exception of workflow, through the appropriate method to deal effectively with the exception to ensure the implementation of the workflow. Most existing research on workflow management systems (WFMS) has been focused on workflow based on well structured...
As the need to meet the high security and reliability requirements of the electric power grids intensify, it is essential to make the existing relays smarter and more adaptive to changing system conditions. A successful implementation of enhanced relay performance requires both improved logic and the ability to manage computing and communications in near-real time. In this paper, we first summarize...
As the power systems in the United States become increasingly large, complex, and interconnected, the traditional relays are proving to be inadequate against blackouts. More "intelligent" relays are therefore needed to meet the security and reliability needs of the future power grid. In this paper, we propose a new logic for decision making and over-current relay setting. The proposed "smart"...
