With the difficulty to define equipment support command process with a formal mathematical formula, a simulation model framework for equipment support command is created. This paper introduces firstly the theory of Agent-Based Modeling (ABM) and its technical structures, analyzes the process of equipment support command. According to the characteristics of equipment support and the method of ABM,...
Remaining useful life (RUL) prediction is a key link in prognostics and health management. More accurate RUL prediction results will lead to more reasonable decision making on sequential management activities including maintenance, replacement, spare parts ordering, etc. In engineering practice, many products exhibit more volatile degradation paths when they have high degradation rates. By this observation,...
Analyze the cases that concepts in ontology are similar, establish a concept similarity computation model based on domain ontology; The computation of concept similarity not only considers the semantic distance between concepts, but also considers the conceptual layer factor and superior concepts coincidence degree, quantizing semantic similarity between concepts nodes in ontology network more comprehensively;...
Tailor rolled blank applied in panels is one of efficient approaches for automobile realizing lightweight, yet the stamping process schemes evaluating is the keypoint. Aimming at the uncertain problem of scheme decision-making for the evaluating parameters are equal or close, the actualized measure based on theory of fuzzy barycenter quadrature was presented to evaluate TRB process schemes, this ensured...
Open environments, like the Internet and corporate intranets, enable a large number of interested enterprises to access, to process and to present information on an as-needed basis. These environments support modern applications, like virtual enterprise (VE), which is a network alliance of cooperating enterprises. VE, involves a number of heterogeneous resources, services and processes. This paper...
For any mature enterprise which has integrated modern management concept, it should have a set of perfect computer decision support system in order to provide a scientific decision basis for the decision maker to carry on management and planning. In this paper, on the basis of automotive integrated supply chain management decision model and the optimized algorithm, a set of automotive integrated supply...
Firms often turn to supply chain management software to systematically standardize operations. But the challenge is that decision makers often find the software hard to master, say nothing of best utilizing the data provided. To input these data into Decision Support Systems (DSS) is a way to bridge the gap between management systems and decision makers. Wholesaler has been deemed as a part of the...
In this paper, we propose a security evaluation model for the web application and define a security evaluation function based on the Analytic Hierarchy Process (AHP) to describe the model. We use the evaluation method proposed by this paper to evaluate the vulnerability test effect of a BBS application named IPB. The experiment result reveals that the evaluation value calculated by the security evaluation...
Fuzzy-rough sets of existing mode are too abstract to the practical problems. It is not of much practical significance. But, the rough-fuzzy sets of existing mode for dynamic data processing capability are poor. This paper proposes new rough-fuzzy sets, which have integrated the advantages of the rough sets and fuzzy sets of data processing better, and have more practical significance for the settlement...
At present, the clinical pathways (CP) is developed and implemented manually by filling predefined paper. Computerization and automatic or semi-automatic implementation of CP based on workflow is one of the possible solutions. By introducing the rule places based on object-oriented Petri net, we build the CP workflow model to solve the workflow route decision-making. However, there are still some...
A cross-impact hierarchy process (CHP), which develops an extended model of the analytic hierarchy process (AHP) that is linked to cross-impact analysis, is a useful decision making tool to deal with dependent technological alternatives. However, the intrinsic drawbacks (i.e., the weight concept being undefined and the priority vector derived form the eigenvalue method (EM) violating a condition of...
