Two-stage flowshop earliness and tardiness machine scheduling involving a common due window

This paper studies a non-preemptive two-stage flowshop scheduling problem to minimize the earliness and tardiness under the environment of a common due window. The window size and the window location are considered to be given parameters. The just-in-time problem exists naturally and has many practical applications. The problem is shown to be NP-complete in the strong sense. We develop a branch and bound algorithm and a heuristic to solve the problem. We conduct the computational experiments to test the performances of the algorithms. A strong lower bound is derived for the branch and bound algorithm that can efficiently solve 15 jobs problem for about 5 minutes. The heuristic is shown to be efficient and effective, which can solve the problem of 150 jobs for about 20 seconds and provide near-optimal solution. We justify that the heuristic is an excellent solution approach for large problem instances. We also show that four special cases are either polynomial solvable or NP-complete in the ordinary sense.

Coping with sales call anxiety: The role of sale perseverance and task concentration strategies

The authors study how salespeople cope with social anxiety during customer contacts and find that two tactics, sale perseverance and task concentration, ultimately reduce dysfunctional protective actions. Both coping tactics, however, are differentially moderated by strength of felt physiological sensations and strength of negative expectations and thoughts. Salespeople experiencing anxiety cognitions should distract themselves by concentrating on their task to free up their thinking in relation to the task at hand. Engaging in behaviors to modify the situation by persevering on the sale, on the other hand, occupies action space and should be the coping strategy of choice for those salespeople confronting physiological sensations in relation to felt anxiety. Hypotheses are tested on a sample of 171 salespersons.

TinyOS任务调度策略改进研究

针对无线传感器网络操作系统TinyOS任务调度策略的不足,该文提出了一种基于快速任务排队算法和动态优先级的FQ—IP任务调度策略。随着无线传感器技术的发展,TinyOS任务队列长度由8增加到了256,这使得任务队列排队算法显得愈发重要,该文提出了一种平均查找长度较小的排队算法,通过仿真测试表明,该算法可以在增加很小的计算开销下显著提高排队速度。同时,本文提出的策略通过定时的增加任务队列中任务的优先级的大小,使得低优先权任务能够在预订的时间范围内得到系统的调度,提高了系统的整体任务吞吐量。
