Beyond compliance and acceptance: Influence outcomes as a function of norm plausibility and processing mode.

A model that can account for influence outcomes beyond the compliance–acceptance dichotomy and that illuminates important conceptual ties between individual and group influence is proposed and tested. In a problem-solving setting, participants who were able to systematically process information complied with implausible majority responses and accepted plausible majority responses. Acceptance generalized to related items and persisted over time. Participants who were unable to systematically process information accepted majority responses, although acceptance neither generalized to related items nor exhibited other characteristics of effortful processing, The latter form of acceptance emerged regardless of norm plausibility, revealing an unanticipated influence outcome, blind acceptance. Discussion centers on implications toward an integrated model of individual–group influence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

无限元法在三维电测井计算中的应用

为了更有效地计算三维电测井资料的响应，在三维数值模式匹配法的基础上引入了一种无限元法。该方法把每层待求解的无限大区域划分为两部分：内部有限区域和外部无限区域。对内部区域，形成传统的矩阵；对外部区域，引入几何中的Kelvin变换，对变换后的场域形成另一个矩阵。内外区域的矩阵在公共边界上耦合，形成三维数值模式匹配法广义特征值矩阵。与原来的三维数值模式匹配法比较，这种新方法减少了形成的广义特征值矩阵维数。结果表明，改进后方法的计算速度比原方法快7倍，而使用内存仅为原方法的1/3，可广泛用于电缆和随钻三维电阻率测井的正反演计算。

An Overview of Optimization Formulations for Multiresponse Surface Problems

Many industrial applications involve more than one quality characteristic. For example, in robust parameter design, the quality characteristics include the process mean and process variance. Such applications lead to multiresponse surface problems in which it is necessary to determine optimal operating conditions according to some specified optimization criterion involving the quality characteristics. The purpose of this article is to address this problem from a multiobjective decision‐making framework. The foremost approaches in multiresponse optimization are categorized and integrated. Guidelines are presented to help select appropriate formulations. Moreover, the applicability and computational aspects of the methods in various decision‐making contexts are discussed. Numerical examples are also provided. Copyright © 2012 John Wiley & Sons, Ltd.     

Book review

Workload control (WLC) is a leading production planning and control (PPC) solution for small to medium sized enterprises (SMEs) and make-to-order (MTO) companies, but when WLC is implemented, practitioners find it difficult to determine suitable workload norms to obtain optimum performance. Theory has provided some solutions (e.g., based on linear programming) but, to remain optimal, these require the regular feedback of detailed information from the shop floor about the status of work-in-process (WIP), and are therefore often impractical. This paper seeks to predict workload norms without such feedback requirements, analysing the influence of shop floor characteristics on the workload norm. The shop parameters considered are flow characteristics (from an undirected pure job shop to a directed general flow shop), and the number of possible work centres in the routing of a job (i.e., the routing length). Using simulation and optimisation software, the workload norm resulting in optimum performance is determined for each work centre for two aggregate load-oriented WLC approaches: the classical and corrected load methods. Results suggest that the performance of the classical approach is heavily affected by shop floor characteristics but no direct relationship between the characteristics and norm to apply could be established. In contrast, results suggest that the performance of the corrected load approach is not influenced by shop floor characteristics and the workload norm which results in optimum performance is the same for all experiments. Given the changing nature of MTO production and the difficulties encountered with the classical approach, the corrected load approach is considered a better and more robust option for implementation in practice. Future simulations should investigate the influence of differing capacities across work centres on the workload norm while action research should be conducted to apply the findings in practice.

Non‐stationary autoregressive processes with infinite variance

Consider an AR(p) process , where {?_t} is a sequence of i.i.d. random variables lying in the domain of attraction of a stable law with index 0<α<2. This time series {Y_t} is said to be a non‐stationary AR(p) process if at least one of its characteristic roots lies on the unit circle. The limit distribution of the least squares estimator (LSE) of for {Y_t} with infinite variance innovation {?_t} is established in this paper. In particular, by virtue of the result of Kurtz and Protter (1991) of stochastic integrals, it is shown that the limit distribution of the LSE is a functional of integrated stable process. Simulations for the estimator of β and its limit distribution are also given.
