An integrated decision-making approach for designing and selecting product concepts based on QFD and cumulative prospect theory

In this paper, both unbalanced linguistic terms and a risk decision-making problem with developers’ bounded rationality are considered; an integrated approach of Quality Function Deployment (QFD) and Cumulative Prospect Theory (CPT) is proposed to help increase customer satisfaction and facilitate product concepts selection. Firstly, QFD is employed to provide a customer-driven tool for developers, which can be used to generate product concept alternatives. Subsequently, enhanced information entropy is utilised to prioritise competing Customer requirements (CRs) based on unbalanced linguistic terms. These terms can be directly processed without being translated into fuzzy numbers, where the risk of information loss in fuzzification can be minimised. Product concept alternatives can be generated based on the outcomes of the subsequent QFD process. Moreover, CPT can be considered as a novel method by incorporating the developers’ psychological characteristics under risk, which can help identify the most relevant product concepts. The cost prospect values of each alternative can be calculated by the function based on the cost reference point. The deficit and profit prospect values can be obtained by aggregating the values and weights of potential results, where functions from the enhanced CPT are used. The order of all alternatives can be ranked based on their overall prospect values. Finally, the proposed approach can be evaluated by a case study concerning the development of a new hydraulic breaker. The deliverables of this study are used to evaluate the relative advantages of the proposed approach over existing multi-attribute utility ones.

Multivariate statistical process control with artificial contrasts

A multivariate control region can be considered to be a pattern that represents the normal operating conditions of a process. Reference data can then be generated and used to learn the difference between this region and random noise. Then multivariate statistical process control can be converted to a supervised learning task. This can dramatically reshape the control region and open the control problem to a rich collection of supervised learning tools. Such tools provide generalization error estimates that can be used to specify error rates. The effectiveness of such an approach is shown here. Such a computational approach is now easily accomplished with modern computing resources. Examples use random forests and a regularized least squares classifier as the learners.     

STEP和XML技术在制造业信息化中的应用

在制造业信息化实施中,必然会应用网络技术,要求产品信息的集成和共享扩展到不受时间和空间的限制。STEP可以成为设计和制造之间的桥梁,而XML则是网络数据的载体。根据产品制造的需要,将CAD系统的输出以相应STEP中性文件的形式存储起来,以利用STEP技术共享制造过程中的产品信息,但是它不能在网络上显示和表达。通过STEP-SML的转换过程,建立XML Schema库,将STEP所存储和表达的产品数据再以XML的形式存储和表示在网络上,最终可以利用XML实现多系统之间产品数据的网络传输。     

Compressibility of liquids: Theoretical basis for a century of empiricism

We show how the successful empirical results of the past century for the compressibility of liquids can be obtained from a recent statistical-mechanical theory that includes dense fluids as well as low-density gases and vapors. The theory also shows to what extent the results for liquids can be extended to dense supercritical fluids and how they can be generalized to any number of dimensions. For simplicity only argon and a Lennard-Jones (12,6) fluid are examined in detail, but the results can probably be extended to real molecular fluids.

A Backscatter Radiography Simulation Study

Backscatter radiography has become a well known inspection technique for the cases where the inspection is to be carried out only for one sided configurations. Compared to the conventional projection radiography, the backscatter radiography has more parameters to be adjusted for a well implemented inspection procedure. The interrogating beam and detector collimation, beam and detector orientation and the distance to the target surface are among those parameters that need to be adjusted. The adjustment of these parameters is not straightforward. A simulation based approach can provide good insight into adjusting the parameters. In this article, we show how simulations can be used for understanding the impact of various parameters. In doing that, we also document how the deterministic methods can prove to be very beneficial since the computations can be done only once and the scattered flux can be computed for various detector configurations without going back to transport computations. Some computational results are provided.     

双参数弹性地基上受压的正交异性板的自由振动

双参数弹性地基上面内受压的正交异性矩形薄板自由振动问题可分两种情况求解;当板的四边为简支时可用双正弦级数解法来求得各阶固有频率。对其他任意边界情形,可采用分离变量法先求得各种代数多项式解以及单正弦级数解,然后建立一个适用于除四边简支外能满足四边以及四角的一般解,其中的积分常数由边界条件来确定。以四边简支和平夹的正方形板为例进行了计算和分析。这种解法简单全面,便于实际应用。全部公式同样可用来求解板的稳定性问题。此时令板的固有频率为零,两个对边压力的比或其中一个为已知即可求得各阶临界压力。
