基于多属性局内决策的应急预案启动模型

通过对突发事件造成损失的连续性扩展和结束时间部分信息的扩展,基于多属性决策方法和集结损失函数,研究管理者面对突发事件应该何时启动应急预案的问题。在没有突发事件损失函数信息的条件下,利用局内决策理论与方法构建了决策者何时启动应急预案的启动模型,并利用竞争比说明了该方案的有效性。在此基础上,通过数值分析验证了启动方案的有效性。     

互文性与网络文学

网络文学就是网络中“在线写作”和阅读的文学样式,是计算机网络媒介与互文本观念联姻的产物。无论就其外在活动方式还是内在精神而言,都体现出明显的互文迹象,它最明显地反映了互文性的特点,是有史以来互文本的最高典范形态。

物流配送管理中的路径优化问题研究

经典的优化理论大多是在已知条件不变的基础上给出最优方案(即最优解),其最优性在条件发生变化时就会失去其最优性。本文提出的局内最短路问题,就是在已知条件不断变化的条件下,如何来快速的计算出此时的最优路径,文章设计了解决该问题的一个逆向标号算法,将它与传统算法进行了比较和分析,并针对实际中的物流配送管理中路径优化问题,按照不同的算法分别进行了详细的阐述与分析。

Time and Work–Life Balance: The Roles of ‘Temporal Customization’ and ‘Life Temporality’

This article poses a challenge to the orthodox binary, conceptualization of work–life balance only made possible by relying on the widespread ‘clock time’ worldview, which understands employment practices in terms of the basic time = money equation. In particular, it is the balance metaphor which relies on a quantification of both work and life in order to make sense and can therefore be seen to be based on an understanding of time as a measurable and value‐able unit. This article seeks to begin the exercise of examining the concept of work–life balance through a broader concept of the temporal dimension than simply limited quantitative notions. Two temporal themes are reported from a study which identified employees who had customized their working pattern to suit the various and multi‐dimensional facets of their lifestyles and thereby successfully improved their work–life balance. Participants in this study demonstrated that an improved work–life balance is more about a mind‐set that refuses to be dominated by a work temporality and is determined to create ‘me time’ rather than e.g. simply choosing a four day week or a part‐time job. It is argued that the notion of work–life balance is more usefully conceptualized within a broader notion of ‘livingscapes’ which contain both elements of work and life and that as researchers, our challenge must be to reflect the complexity of this weave within our analyses of individuals’ work–life balance.     

Mass Customization in the Automotive Industry: Comparing Interdealer Trading and Reconfiguration Flexibilities in Order Fulfillment

Mass customization has been viewed as desirable but difficult to achieve in the volume automotive sector. Here we consider flexibility in automotive order fulfillment systems to enhance the ability to satisfy customers with their desired vehicle variants within acceptable delivery lead times. Two types of flexibility are compared in a Virtual‐Build‐to‐Order system—reconfiguration in the planning pipeline and interdealer trading. A representative simulation model is used to investigate the impact of the two types of flexibility across a wide spectrum of product variety levels. The impacts on major stakeholders in the system—the producer, dealers, and customers—are considered. The study shows that both types of flexibilities can bring significant benefits in terms of reductions in lead time and inventory holding. The level of product variety strongly influences the observed effects—an important finding in the mass customization context. Upstream reconfiguration flexibility brings greater benefits than downstream trading flexibility. Reconfiguration tends to dominate trading as a fulfillment mechanism when both are in operation. The findings have implications for the design and management of automotive order fulfillment systems in improving their ability to offer mass customization. The study has relevance for companies in other sectors with high levels of variety that seek to combine efficiency, speed, and flexibility in order fulfillment.     

On-Line Scheduling of Two-Machine Open Shops Where Jobs Arrive Over Time

We investigate the problem of on-line scheduling two-machine open shops with the objective of minimizing the makespan.Jobs arrive independently over time, and the existence of a job is not known until its arrival. In the clairvoyant on-line model, the processing requirement of every job becomes fully known at the arrival of the job, while inthe non-clairvoyant on-line model, this processing requirement is notknown until the job is processed and completed.In both models, scheduling of a job is irrevocable.We study the two-machine open shop problem for both models in the preemptive and in the non-preemptive version. For each of the four variants, we provide an algorithm that is best possible with respect to the worst-case performance. In the clairvoyant on-line model, the best worst-case performance ratios are 5/4 (preemptive) and 3/2 (non-preemptive), and in the non-clairvoyant on-line model, they are 3/2 (preemptive and non-preemptive).
