对越轨功能的新认识

对越轨功能的认识具有重要意义,但以往对越轨功能的认识仅停留在现象层面,深入到人类发展的内在过程和社会运行机制层次加以分析,可以发现越轨有若干独特的积极功能。由对越轨的这种认识,可以恰当地确定我们对越轨的态度和应对策略。     

Life distribution analysis based on Lévy subordinators for degradation with random jumps

For a component or a system subject to stochastic degradation with sporadic jumps that occur at random times and have random sizes, we propose to model the cumulative degradation with random jumps using a single stochastic process based on the characteristics of Lévy subordinators, the class of nondecreasing Lévy processes. Based on the inverse Fourier transform, we derive a new closed‐form reliability function and probability density function for lifetime, represented by Lévy measures. The reliability function derived using the traditional convolution approach for common stochastic models such as gamma degradation process with random jumps, is revealed to be a special case of our general model. Numerical experiments are used to demonstrate that our model performs well for different applications, when compared with the traditional convolution method. More importantly, it is a general and useful tool for life distribution analysis of stochastic degradation with random jumps in multidimensional cases. © 2015 Wiley Periodicals, Inc.

支持社会技术系统构造的程序设计模型和语言

互联网上越来越多软件系统呈现出社会与技术交融、环境多样和开放、系统动态和演化等特点,如何支持这类复杂软件系统的构造是软件工程面临的一项重要挑战。通过将社会技术系统视为多Agent组织,把社会组织学的概念和思想引入到面向Agent程序设计范畴,提出了以Agent、组织、角色和职位为核心的基于组织程序模型来支持社会技术系统的开发;通过对多Agent组织不同层次动态性的识别和分析,设计了一组程序设计机制来实现社会技术系统的动态演化;包括角色绑定和组合机制、基于角色的交互机制以及组织的自我管理机制。基于上述模型和机制,提出了社会技术系统程序设计语言OragentL,给出了OragentL程序在组织、角色和组合三个层次的语法形式定义,介绍了OragentL的编译器及其运行支撑环境OragentBurg,并通过案例分析和演示展示了研究成果的有效性。

An exact branch‐and‐price algorithm for multitasking scheduling on unrelated parallel machines

We consider the multitasking scheduling problem on unrelated parallel machines to minimize the total weighted completion time. In this problem, each machine processes a set of jobs, while the processing of a selected job on a machine may be interrupted by other available jobs scheduled on the same machine but unfinished. To solve this problem, we propose an exact branch‐and‐price algorithm, where the master problem at each search node is solved by a novel column generation scheme, called in‐out column generation, to maintain the stability of the dual variables. We use a greedy heuristic to obtain a set of initial columns to start the in‐out column generation, and a hybrid strategy combining a genetic algorithm and an exact dynamic programming algorithm to solve the pricing subproblems approximately and exactly, respectively. Using randomly generated data, we conduct numerical studies to evaluate the performance of the proposed solution approach. We also examine the effects of multitasking on the scheduling outcomes, with which the decision maker can justify making investments to adopt or avoid multitasking.
