Benders' cuts guided large neighborhood search for the traveling umpire problem

This article introduces the use of Benders' cuts to guide a large neighborhood search to solve the traveling umpire problem, a sports scheduling problem inspired by the real‐life needs of the officials of a sports league. At each time slot, a greedy matching heuristic is used to construct a schedule. When an infeasibility is recognized first a single step backtracking is tried to resolve the infeasibility. If unsuccessful, Benders' cuts are generated to guide a large neighborhood search to ensure feasibility and to improve the solution. Realizing the inherent symmetry present in the problem, a large family of cuts are generated and their effectiveness is tested. The resulting approach is able to find better solutions to many instances of this problem. © 2011 Wiley Periodicals, Inc. Naval Research Logistics, 2011     

Polynomial‐time approximation scheme for concurrent open shop scheduling with a fixed number of machines to minimize the total weighted completion time

In this article, we consider the concurrent open shop scheduling problem to minimize the total weighted completion time. When the number of machines is arbitrary, the problem has been shown to be inapproximable within a factor of 4/3 ‐ ε for any ε > 0 if the unique games conjecture is true in the literature. We propose a polynomial time approximation scheme for the problem under the restriction that the number of machines is fixed. © 2011 Wiley Periodicals, Inc. Naval Research Logistics, 2011     

Batch scheduling on a two‐machine jobshop with machine‐dependent setup times

The problem of minimum makespan on an m machine jobshop with unit execution time (UET) jobs (m ≥ 3) is known to be strongly NP‐hard even with no setup times. We focus in this article on the two‐machine case. We assume UET jobs and consider batching with batch availability and machine‐dependent setup times. We introduce an efficient \begin{align*}(O(\sqrt{n}))\end{align*} algorithm, where n is the number of jobs. We then introduce a heuristic for the multimachine case and demonstrate its efficiency for two interesting instances. © 2011 Wiley Periodicals, Inc. Naval Research Logistics, 2011     

A genetic algorithm with neighborhood search for the resource‐constrained project scheduling problem

The resource‐constrained project scheduling problem (RCPSP) consists of a set of non‐preemptive activities that follow precedence relationship and consume resources. Under the limited amount of the resources, the objective of RCPSP is to find a schedule of the activities to minimize the project makespan. This article presents a new genetic algorithm (GA) by incorporating a local search strategy in GA operators. The local search strategy improves the efficiency of searching the solution space while keeping the randomness of the GA approach. Extensive numerical experiments show that the proposed GA with neighborhood search works well regarding solution quality and computational time compared with existing algorithms in the RCPSP literature, especially for the instances with a large number of activities. © 2011 Wiley Periodicals, Inc.

基于模糊AHP的武警分队处突效能评估

当前国内局势不太稳定,武警部队作为处置突发事件的主要力量,必须随时做好战备工作。通过分析影响武警分队处突效能的主要因素,建立了武警分队处突效能评估指标体系,给出评估模型。利用层次分析法AHP(The Analytic Hierarchy Process)确定各指标的权重,应用专家打分法确定单因素评判矩阵,最后运用模糊综合评判模型对某武警分队处突效能进行评估。评估结果与处突分队现实表现能力相一致。该方法不仅可以为首长机关在处突时提供决策支持,而且还可以根据评估结果对该分队的短板进行针对性训练,提高战斗力。

飞行器试验多测控目标发射零点应急处理方法

飞行器飞行试验任务中,发射零点T0是整个测控系统启动运行的基准点,是保证测控系统有条不紊正常工作的关键因素。特别是执行多个测控目标连射飞行试验任务,多个发射零点的正确处理更是关乎试验任务的成败。在分析发射零点形成机制基础上,对发射零点在指控系统实时测控软件中的处理方法进行了研究,提出了一种实时测控软件重启后重新获得多测控目标正确发射零点的应急处理方法,解决了试验过程中一旦实时测控软件因重大软件故障导致初始发射零点丢失的问题,保障了试验任务的顺利进行。
