基于可能度的坦克分队进攻战斗作战方案决策方法

将不确定属性决策理论和方法应用于坦克分队进攻战斗作战方案的决策,提出了一种基于可能度的坦克分队进攻作战方案决策方法,主要用于解决在决策过程中由于决策属性值是区间数而导致的不确定性问题。首先定义了基于可能度的坦克分队进攻作战方案决策的相关概念,然后阐述了基于可能度的坦克分队进攻作战方案决策步骤,最后给出了基于可能度的坦克分队进攻作战方案决策示例。研究表明,基于可能度的坦克分队进攻战斗作案决策方法特别适用于决策属性值为区间数而权重为确定实数的情况。

An efficient metaheuristic for integrated scheduling and staffing IT projects based on a generalized minimum cost flow network

Scheduling IT projects and assigning the project work to human resources are an important and common tasks in almost any IT service company. It is particularly complex because human resources usually have multiple skills. Up to now only little work has considered IT‐specific properties of the project structure and human resources. In this article, we present an optimization model that simultaneously schedules the activities of multiple IT projects with serial network structures and assigns the project work to multiskilled internal and external human resources with different efficiencies. The goal is to minimize costs. We introduce a metaheuristic that decomposes the problem into a binary scheduling problem and a continuous staffing problem where the latter is solved efficiently by exploiting its underlying network structure. For comparison, we solve the mixed–binary linear program with a state–of–the–art commercial solver. The impacts of problem parameters on computation time and solution gaps between the metaheuristic and the solver are assessed in an experimental study. Our results show that the metaheuristic provides very favorable results in considerable less time than the solver for midsize problems. For larger problems, it shows a similar performance while the solver fails to return feasible solutions. © 2012 Wiley Periodicals, Inc. Naval Research Logistics 59: 111–127, 2012

对Sosemanuk算法改进的猜测决定攻击

Sosemanuk算法是欧洲eSTREAM计划最终获选的七个算法之一。从比特层面对该算法进行剖析,通过对Serpent1组件S盒、模232加法和线性反馈移位寄存器的研究,找到了关于内部状态的一个方程组,并利用Groebner基方法改进了对Sosemanuk算法基于字的猜测决定攻击。结果表明只需要猜测7个32比特的字就可以完全确定出其余5个32比特的内部状态,其攻击的复杂度为O(2192)。
