A K -sample testing problem is studied for multivariate counting processes with time-dependent frailty. Asymptotic distributions and efficiency of a class of non-parametric test statistics are established for certain local alternatives. The concept of efficiency is to show that for every non-parametric test in this class, there is a parametric submodel for which the optimal test has the same asymptotic power as the non-parametric one. The theory is applied to analyse a diabetic retinopathy study data set. A simulation study is also presented to illustrate the theory 相似文献

In electrical engineering, circuit designs are now often optimized via circuit simulation computer models. Typically, many response variables characterize the circuit's performance. Each response is a function of many input variables, including factors that can be set in the engineering design and noise factors representing manufacturing conditions. We describe a modelling approach which is appropriate for the simulator's deterministic input–output relationships. Non-linearities and interactions are identified without explicit assumptions about the functional form. These models lead to predictors to guide the reduction of the ranges of the designable factors in a sequence of experiments. Ultimately, the predictors are used to optimize the engineering design. We also show how a visualization of the fitted relationships facilitates an understanding of the engineering trade-offs between responses. The example used to demonstrate these methods, the design of a buffer circuit, has multiple targets for the responses, representing different trade-offs between the key performance measures. 相似文献

This paper is concerned with the organizationalchange and project management issues raised by theimplementation of a business process re-engineering(BPR) approach in the politicized hospital context. This is a report of research in progress,focusing on the issues arising at the problem definitionand project planning stages of a BPR application in anoperating theaters department experiencing problems with scheduling and delays. The research designrelies on a case study approach, with the researcher asparticipant observer, as both an adviser to the projectteam and as field interviewer. The paper argues that an ambitious BPR agenda is compromised inat least two regards. First, the lack of precisionsurrounding the focus and methodology of BPR givespolitically motivated actors considerable influence with respect to defining terms of reference in wayswhich will shape potential outcomes in their favor.Second, the complexity and indeterminacy of the businessprocess or patient trail can also diluteredesign attempts. The principal limitations of theapproach thus concern the impracticality of embarking onrapid and radical change working from a blanksheet of paper with respect to organizational and job design. BPR, unlike other organizationdevelopment interventions, is not a contextsensitive approach. The role of project manageris critical in establishing a working balance betweenindividual, occupational, and organizational goals in a manner perceivedto be legitimate in the context. Effective BPR projectmanagement thus requires a combination of political andprocess analysis skills. The principal opportunities of BPR derive from its process orientation,which brings a fresh perspective to a traditionally andfunctionally fragmented organizational setting, andwhich presents a potentially valuable platform for anevolutionary approach to process improvement. 相似文献

Consider the process with, cf. (1.2) on page 265 in B1, X1, …, XN a sample from a distribution F and, for i = 1, …, N, R , the rank of |X1 - q1ø| among |X1 - q1ø|, …, |XN - qNø|. It is shown that, under certain regularity conditions on F and on the constants pi and qi, TøN(t) is asymptotically approximately a linear function of ø uniformly in t and in ø for |ø| ≤ C. The special case where the pi and the qi, are independent of i is considered. 相似文献

Application of software for manufacturing processes is one of the resolutions many enterprises have resorted to in the 21st century. This has been a result of increased complexity of products, globalization, rapid changes in technology and so on. The idea was that application of software especially for product development would increase the competitive advantage of industry nevertheless the irony has been that most of the investment in software has not achieved the expected results. We carry out a case study to introduce a methodology, the analytical network process as a multiattribute strategic decision making approach to help in the selection of appropriate software to suit the product development process of a particular product. 相似文献
