Abstract&Keyword Cite

Abstract :

In order to deal with the management problems which embodies "path dependence" and "context-sensibility" more effectively, a hybrid system which integrates the methods of ESBSA(Expert System Based on Scenario Analysis)with other KBR(Knowledge Based Reasoning) sub-systems is established. The problem-solving ability of ESBSA will be improved consequently by the integration which is based on the classification of the related knowledge. The model of this hybrid system is discussed in details.

Abstract :

To successfully develop a region's or country's economy, policy-makers have to utilize foreign investments. To attract the right foreign investors, the host has to understand not only the investors, but more importantly its own investment environment. This article presents a practical method for evaluating investment environment from the viewpoint of a host region or country. A real Chinese case was analysed by applying this method. The evaluation method is recommended not only to China, but also to those countries having investment environments similar to China's. (C) 1997 Elsevier Science B.V.

Abstract&Keyword Cite

Abstract :

A virtual company is a temporarily organized "productive facility". Through the Information Expressway, it can share information about social manufacturing resources and market demands. On the basis of the principles of Agile Manufacturing (AM), a mold & die center could actually be set up as a "virtual company". It can take full advantage of the superiorities in terms of human and facility resources of a variety of mold & die manufacturing enterprises to supply the vast and competitive mold and die market with high-quality products coupled with the fastest delivery and the lowest cost.

Numerical analysis on heat transfer and fluid flow for arrays of non-uniform plate length aligned at angles to the flow direction EI SCIE Scopus

Abstract&Keyword Cite

Abstract :

The periodically fully developed laminar heat transfer and fluid flow of an array of non-uniform plate length, aligned at angles to air flow direction, have been investigated by numerical analysis in the Reynolds number range from 15 to 410. To implement the periodic boundary condition in both streamwise and spanwise directions and to confine the computation exactly within one cycle, proposes a linear interpolation technique, which has been proved successful by comparing the results with those obtained in an extended domain. It has been found that with an increase in the ratio of the long plate length to that of the short plate and with a decrease in the ratio of the transverse pitch to the streamwise cycle length, both the Nusselt number and friction factor decrease. Comparison of the numerical results of Nusselt number and friction factor with relevant experimental results have been performed. The agreement should be judged reasonably good.

The development of a consultation expert system for metal materials processing and manufacturing SCIE Scopus

Abstract&Keyword Cite

Abstract :

In this paper, a research work on the development of a consultation expert system for metal materials processing and manufacturing (ESMMPM) is presented, which can be run under Chinese DOS and programmed by PROLOG and C. A three-dimensional domain framework consisting of surface processing technologies, failure types, and machine components is proposed, from which the expert knowledge can be acquired. A method of combining predicate logic with production rules is applied to represent knowledge. A hybrid inference strategy is employed in which backward inference computation is used as a major tool, and forward inference as an auxiliary one. The knowledge base can be easily updated, deleted and added to in operation. The development of a cold forming tools subsystem has been completed, and the further development work based on neural networks and genetic algorithms is continuing.

Strip model plasticity analysis of mixed mode crack opening displacement in aluminum alloy LY12 SCIE Scopus

Abstract :

Under mixed mode loading, the crack tip blunts and undergoes displacements in two directions, the normal and shear component corresponding to Mode I and Mode II loading, respectively. These local displacements are determined by the duplicated film method and used to analyze the behavior of mixed mode fracture in aluminum alloy LY12. The mixed mode resultant crack opening displacement (GOD) at fracture initiation tends to increase more rapidly with increase of the Mode II shear component, The fracture initiation value of COD for pure Mode II loading is six (6) times greater than that for Mode I loading, The same applies to the maximum effective plastic strain crack growth near the crack front. Observed are two typical morphologies, the equal-axes dimples and the parabolic dimples with evidence of slippage as dominated, respectively, by Mode I and Mode II loading.

A new subgraph of minimum weight triangulations SCIE Scopus

Abstract :

In this paper, two sufficient conditions for identifying a subgraph of minimum weight triangulation of a planar point set are presented. These conditions are based on local geometric properties of an edge to be identified. Unlike the previous known sufficient conditions for identifying subgraphs, such as Keil's beta-skeleton and Yang and Xu's double circles, The local geometric requirement in our conditions is not necessary symmetric with respect to the edge to be identified. The identified subgraph is different from all the known subgraphs including the newly discovered subgraph: so-called the intersection of local-optimal triangulations by Dickerson et al. An O(n(3)) time algorithm for finding this subgraph from a set of n points is presented.
