Better Together: Responsive Community Programming at the U-M Library

In the past seven years, the University of Michigan Library's programming model has evolved to be responsive and reflective of staffing areas of interest and expertise. Our team-based, iterative model enables us to develop responsive exhibits, workshops, experiences, and events in our community. This article explores our experiences in developing this model through the lens of some of our collaborations with the Ann Arbor District Library (AADL). Our approach to programming opportunities builds on learning by doing, building deeper, mutually beneficial relationships with other organizations, and continually making sure we are truly developing programming with our audience (our community) in mind. While public and academic libraries often develop distinct sets of services, collections, and expertise to serve their respective communities, successful collaborations can yield interesting opportunities for more effective engagement and programming. Our relationship with AADL has helped us to identify and better understand how we can connect our teaching and research missions with the interests and needs of the broader community in which we are situated.

0-1整数规划最优模型在物品设计中的应用

以储药柜的设计为例介绍了0-1整数规划数学模型在物品设计方面的应用。药房内的盒装药品种类繁多,药盒尺寸规格差异较大,一般的储药柜为横纵向等距的设计方案,药盒与两侧竖向隔板之间的间隙会造成宽度冗余,药盒与上面隔板的间隙会造成高度冗余。增加竖向隔板的间距类型数量可以有效地减少宽度冗余,但会增加储药柜的加工成本,同时降低了储药槽的适用范围。研究确定储药柜横纵向隔板间距的类型数量,使得储药柜的总平面冗余量尽可能地小,对现实中储药柜的设计具有重要的指导意义。     

一类邮递员送信问题

本文讨论了一类有约束的邮递员送信问题,不同于经典的TSP(Travelling Salesman Problem)问题,它要求经过部分顶点一次且仅一次,回到初始点的最短路径.这里建立了0-1规划模型,给出了求解此问题的一种方法,对于类似邮路问题有一定的借鉴意义.

Expert group formation using facility location analysis

In this paper, we propose an optimization framework to retrieve an optimal group of experts to perform a multi-aspect task. While a diverse set of skills are needed to perform a multi-aspect task, the group of assigned experts should be able to collectively cover all these required skills. We consider three types of multi-aspect expert group formation problems and propose a unified framework to solve these problems accurately and efficiently. The first problem is concerned with finding the top k experts for a given task, while the required skills of the task are implicitly described. In the second problem, the required skills of the tasks are explicitly described using some keywords but each expert has a limited capacity to perform these tasks and therefore should be assigned to a limited number of them. Finally, the third problem is the combination of the first and the second problems. Our proposed optimization framework is based on the Facility Location Analysis which is a well known branch of the Operation Research. In our experiments, we compare the accuracy and efficiency of the proposed framework with the state-of-the-art approaches for the group formation problems. The experiment results show the effectiveness of our proposed methods in comparison with state-of-the-art approaches.     

时变条件下的危险品运输与应急救援双层规划研究

危险品运输因其发生事故的后果危害性大,因此对于如何选择一条既能保证运输安全又能满足运输需求的最优路径已经成为一项非常重要的研究内容。在总结前人研究的基础上,提出在时变条件下考虑应急救援的危险品运输路径双层规划模型,同时考虑运输时间限制与出发等待时间弹性以及运输网络中的应急救援能力。通过算法求解与应用算例,结果表明:双层规划更好地描述了企业和政府之间的博弈决策,而且将应急救援因素作为路径选择的重要依据有利于寻求更符合实际的最优路径。
