探讨模拟数学在学术论文搞质量综合评价中的应用

首先提出，目前仍采用三审制，以语言设计院评价学术文稿质量，其结果模糊，缺乏量化、缺乏稿件之间的可比性，还受到评价人人为因素的影响，有失公正性，探讨应用模糊数学方法评价论文稿质量的可行性，介绍同属模糊数学范畴的方法一和方法二的运用过程，并将运用两方法的结果作比较，提出：方法二的基本内容是主因素决定型的数学模型M（∧，∨），其运用结果仍显模糊，缺乏准确性；方法一简单，实用，结果直观，因为其运用过程中采用了以百分数表达的单因素评价矩阵与几项权重向量的合成运算，运用方法一，可促进编辑部审稿工作的程式化，标准化、自动化。     

Transport and society1

In 1963, the Buchanan Report in the UK advocated a combination of new road capacity, improved public transport and traffic restraint as a means to tackle congestion. Forty years on, and the advice from many transport experts remains the same. However, the scale and complexity of the problems associated with a mobility‐dependent society have grown. The need for politicians to make tough but realistic policy decisions on transport is now becoming unavoidable. They must confront the realities of living with the car as must the general public. Policymakers now also have social well‐being and sustainable development moving higher on their agendas alongside transport. Against such a backdrop, the paper makes the case for transport research, policy and practice to acknowledge more fully the inherent links between transport and society. It argues that greater recognition and understanding of such links is crucial to confronting the present realities. Transport does not merely serve society: it shapes society, as in turn society shapes transport. The future of each is dependent on the other, and this fact must be recognized. The paper advocates in turn that the transport profession must move from its heartlands in engineering and economics also to embrace more fully such disciplines as sociology and psychology. A factual picture of the many facets of present‐day society is presented and the implications for travel demand are discussed. Through considering phenomena such as social norms and habitual behaviour, it is then argued that the travel choices and behaviour of individuals are not simply a matter of economic optimization. This points to the need for decision‐makers to be furnished with better evidence about the transport problems faced and the potential efficacy of measures that might be taken. Discussion of public attitudes and the role of the media are included in the context of assessing how politicians can be encouraged and supported in their implementation of realistic but unpopular policies. Evidence and experience within the paper are UK based, although many of the issues and arguments apply world wide.

基于图论与故障树结合的控制系统故障诊断

探讨了一种图论与故障树结合的方法，可用于复杂控制系统的故障诊断，主要采用故障树图论模型的算法实现系统的故障诊断。图论（有向图）可直观反映故障传播关系，把故障节点分层，用矩阵表示节点与顶事件的关系，通过矩阵运算出各层节点到顶事件的通路长度，通过底事件的失效率算出各节点关键重要度，确定每条通路的权值，进而确定每一层故障节点的排查次序。矩阵表示便于计算机处理，避开了寻找故障树割集或路集的困难，提高了诊断效率。
