This paper focuses on the problem of college physical teaching quality evaluation, which is of great importance in modern education. Firstly, we propose an index system for evaluating the quality of college physical teaching, and it can cover many influencing factors of college physical teaching quality estimating. Secondly, we propose a fuzzy AHP based college physical teaching quality evaluation...
The main object of workflow description is to map business requirements quickly and accurately mapped to business process. An approach of business semantic-oriented workflow description method is proposed aiming at the current workflow description method lack of resource allocation means oriented business staff. It provides a description way that business staff familiar with through which business...
Considering the shortcomings of the attribute weight setting method used currently in the decision model of choosing project transaction mode, which is typically characterized by precise weights, the stochastic problem of index weight of multi-attribute comprehensive evaluation is researched. Under the weight interval information is chosen, the stochastic weight assignment method is used to determine...
In this paper, the existing products' status about mechanical life-saving parachute device or unlock device is analiszed, and the key problems in specific design of multistate program control parachute is shown and illustrated. The prototype is development, which is formed mainly by PC104 as control core, 3-dimensional electrom compass as sensors and ball lock mechanism as release machine. Princinple...
With MoldFlow, the injection molding process of the fan back cover is simulated. The cover's structure is analyzed and its 3-D model is girded and improved. The filling process is studied with the gate's different forms and locations from the weld line, cavitation and so on, and the gate design is optimized. The warpage deformation and volume shrinkage in different processing parameters are analyzed,...
Mergers & Acquisitions (M&A) is an important way to expand the enterprises' scale and improve their core competitiveness, but M&A decision is a big challenge for the manager, especially in the highly uncertain environment. The main approach to value M&A by traditional financial theory is discounted cash flow (DCF) model. DCF models are used for M&A evaluation by most companies,...
As service behavior plays a key role in service interaction, behavior-based service discovery has been increasingly recognized as a critical activity for service-based systems. However, little attention has been paid to the retrieval of behavioral models, which is critical for behavior-based discovery. This paper proposes an approach for extracting service behavioral models from WS-BPEL, which has...
Through 335 questionnaires collected from 22 corporations in our survey, the two key factors which can influence the employee's knowledge reception readiness in the process of knowledge transfer, namely the degree of knowledge customization and the reliability of the knowledge source, are studied empirically. Moreover, the mediate effect of the employees' involvement degree and specialization degree...
In the research of software reuse, feature models have been widely adopted to organize the requirements of a set of applications in a software domain. However, there still lacks an effective approach to minimizing analysts' participation in feature models' construction. In this paper, we propose a use case based semi-automatic approach to the construction of feature models. The basic idea of this...
In this paper, by Logit regression technology, we construct a model for recognizing and warning credit risk based on financial and non-financial ratios. The testpsilas results show that the accuracy of the model is up to 86.6%. Obversely, it can offer enterprise some supports for recognizing and warning credit risk in credit sale.
Adopting game theories, this paper has analyzed on the judgments and strategies between enterprisespsila purchasers and suppliers under static and dynamic environment, when they have perfect information and imperfect information. Through the establishment of a principal-agent game model, the results show that the positive supply attitude of suppliers and incentive mechanism of purchasing enterprises...
Software architectures are considered the key means to manage the complexity of large-scale systems from the high abstraction levels and system-wide perspectives. The traditional software design methodologies and the emerging architecture design methods still fall short of coping with the architectural complexity and difficulty in practice. The recent research on the architecture design decisions...
The rapid progress of GIS application has put forward higher demands to GIS software. Although the secondary development capabilities and degree of openness of GIS software have improved greatly now, but there are still many problems, such as the inadequacy of spatial data handling and analysis capacity, poor openness, difficult sharing of data and services. The paper provides a solution of rapid...
A model is a blueprint of a system, which influences the quality of the system. A high quality model should specify not only the functional attributes of a system, i.e., what the system can do, but also the non-functional attributes, i.e., how well the system can do. Modeling for non-functional attributes, especially, the integration of nonfunctional attributes description with functional description...
