    ABSTRACT: This paper models the aeroengine health assessment problem as a multi-criteria decision-making (MCDM) problem and proposes a three-step evaluation model, which combines the techniques of fuzzy analytic hierarchy process (fuzzy AHP), fuzzy preference programming (FPP) and technique for order performance by similarity to ideal solution (TOPSIS). Fuzzy AHP and FPP methods are used to determine the relative weights of multiple evaluation criteria and synthesize the ratings of candidate aeroengines. Aggregated the evaluators’ attitude toward preference, then TOPSIS is employed to obtain a crisp overall performance value for each alternative to make a final decision. To illustrate how the approach is used for the aeroengine health assessment problem, an empirical study of a real case involving eleven evaluation criteria and ten initial commercial aeroengines of Air China Ltd. is conducted. The case study demonstrates the effectiveness and feasibility of the proposed evaluation procedure.

    ABSTRACT: Mandibular defects need customized titanium plates for reconstruction. The conventional design process of titanium plate is prior to surgical interventions. The efficiency and accuracy of the conventional method is mainly dependent on experiences and skills of the designer. In order to decrease the dependence on design experience and enhance the participation of surgeons in the design process, designing and fabricating a customized titanium plate implant according to Rapid Prototyping (RP) biomedical model could be employed. RP biomedical model is greatly convenient to diagnosis and treatment planning. It could decrease the operation time and the risk of misinterpretation of the medical problem. In these cases, the operation time was reduced by 1.5-2.5 hours. A physical biomedical model also facilitates surgery planning and makes the rehearsal and simulation of the operation possibly. The customized titanium plate shape conforms to the patient's mandible anatomy and is thick enough to provide the strength and stiffness needed to fix the mandible until the bone grafts and soft tissues heal. At the same time it is thin enough to avoid extensive intrusion into soft tissues and to avoid weighing too much for the patient's jaw.

    ABSTRACT: The traditional study on grinding is testing the same material in conditions of different grinding parameters on a dedicated grinder, or testing different materials separately, which will not only waste a lot of human and material resources, but also extend the research and development cycle of wheel products, increase wheel product development costs, reduce the efficiency of study. If virtual reality and simulation technology are used to replace or reduce the actual experimental work, the grinding wheel manufacturing costs can be decreased and the competitiveness of R & D departments are increased, especially the diamond, CBN and others higher-cost super hard abrasives. This paper briefly introduce to some of the basic theory about the virtual reality simulation technology, then develop the grinding process modeling and simulation system of vitrified bond CBN grinding wheel by the MFC with OpenGL graphics library in the Microsoft Visual C + + 6.0 platform. After system simulation testing, the wear state of vitrified bond CBN grinding wheel on different conditions and different periods in the grinding process are predicted.
