After the article introduces the basic concepts of the information tree and information visualization and displays image, with its Delphi 6.0 programming tools and university evaluation of database management systems as examples, the article discusses the process of building information tree, and gives information tree the specific algorithm and part of program about the most widely used traversal...
Based upon the summary of software quality management, this paper concretely sets forth the quality management model of “Three-layer and Four-field” and the measures of the application software of the information system, and clearly puts forward the work emphases, such as promoting software engineering practice, specifying software classification management, strengthening software design quality,...
At present, the software project risk management as an emerging management theory, have attracted domestic and foreign large numbers of software project management staff of all ages, and they have achieved certain results. this article reviewed the research results made by domestic and foreign scholars in this area, reviewed the software industry and software development process of project risk management,...
Management information system is a marginal cross discipline that is featured with comprehensiveness. Through the analyses of the factors influencing the teaching of management information system in the specialty of industrial and commercial management, the paper proposes the application of contingency theory to solve the problems with teaching practice reform of management information system. It...
Computer experiments play a very important role in computer major education. How to make the students master various computer skills better by the experiments is always a big challenge for the teachers. Here the method of micro-test is put forward to improve the experimental effect. Combined with some major factors like the course's features, the students' knowledge structure, their psychology, the...
The discrete characteristic of data points leads to the visualization of three dimensional meshless method numerical results with difficulty. This paper proposes using three dimensional Delaunay tessellation, which constructs the background tetrahedron mesh from three dimensional data points, to visualize numerical results of meshless method with cloud contour by coloring the 4 triangular facets of...
The actual flexible job-shop scheduling problem usually involves multiple objectives optimization, more than one resource constraint and uncertain operation time. The model of dual-resource multi-objective flexible job shop scheduling problem, which considers dual-resource constraints of machines and workers and uncertain operation time constraint, is established, and it takes delivery satisfaction,...
Prolog is a declarative language that describes problems by facts and rules and solves problems by searching, matching and backtracking mechanism, which is particularly applied to symbol reasoning. This paper firstly introduces the main features and basic structure of Prolog and then presents the expression of three kind of control structure in structured programming language by interior predicate...
This paper studies from the next three aspects as follows: Firstly, this thesis introduces CRM theory and Network Marketing conception. Secondly, this paper analyzes the relationship between CRM and Network Marketing. Thirdly, Maibaobao Aveyond is illustrated as a case to analyze its application situation and put forward some proposals of CRM in Network Marketing.
This paper discusses the VaRU minimization portfolio selection problem assuming that the return rates of risky securities are uncertain variables. Considering the realistic financial market, we propose a new model which adds the integer constraint of the transaction lot. Then the crisp form of the model is given. In the meanwhile, a revised branch-and-bound method is introduced in the paper. Finally,...
Inspired by the basic concepts of CAS, this paper suggests that firms' adaptive behaviors are one of the driving forces which push the evolution of industrial clusters, and hence proposes Swarm simulation model of the evolution of industrial clusters based on multi-agents games. The impacts and effects of the geographical factors are discussed. By the analysis of the simulation results, this paper...
Under the premise of user equilibrium criterion, a bilevel programming model, which regards the most optimal income of the water suppliers and the least water costs of users as targets, is established to describe optimal allocation of water resources. Finally, the application of the model and its algorithm are illustrated with a simple example.
In this paper, a new method is proposed to obtain the interval weights from interval reciprocal comparison matrices. Firstly, some basic theorems about consistent interval reciprocal comparison matrix are presented. Then, based on the theorems, an algorithm is proposed to approximate a column of approximated intervals which contains all of the consistent information. Furthermore, another algorithm...
The system is an open one and the examination topics databases can be browsed, appended and edited by users, the contents of the topics can be anything which can be recognized and accepted by application Word; This system can create examination topics Databases for many different curricula and manage their own databases by users using its corresponding functions; All the automatically saved examination...
The purpose of this study is to discuss risk deal scheme decision methods for real estate projects. The paper puts forward the fuzzy multi-target risk deal scheme decision model for real estate projects by the research of multi-target risk decision problem with uncertain hobby information, this model can translate multi-targets risk deal scheme decision into single target risk deal scheme decision.
The two sets of management systems formed by the project team built under the matrix organization structure, vertically and horizontally are not only to the benefit of the centralization of leadership, but also to the cooperation and complement of team members. The key of the problem is how to choose the suitable members for the project team according to the needs of different projects. Based on this,...
Along with computer technology and hydraulic skill development, the application of Artificial Intelligence in water conservancy has been extending. In the article the author introduced two main respects: he important skill and the system in working out water resources distribution plan. T he purpose is to help management water resources in the river basin.
Software reliability analysis is a significant measure to guide design of software reliability. Now software fault tree method to carry on software reliability analysis is used more and more. But it can only qualitative carry on the analysis because of many reasons. For example, the scale of software is enlarging, the software architecture is getting more and more complex, the reason of software fault...
Multidisciplinary design optimization (MDO) is a methodology for the design of complex engineering systems and subsystems that coherently exploits the synergism of mutually interacting phenomena. Because of the complex design space of the large-scale system MDO design problem and the serious conflicts between the different design objectives, there is the necessary to seek an objective, flexible, effective...
Computer security has always been the one that is an important and serious issue. The stability of the running program design often becomes important for judging the success. The stability of the code is not only a security issue, or computer programming is crucial and related areas of basic research is important. This article introduced the concept of stability of the significance and importance...
