中小型房地产经纪机构电子商务平台架构

对于中小型房地产中介企业而言，建立完善的电子商务应用系统需要的巨大投入阻碍了电子商务在这些表现活跃的房地产交易中坚力量中的发展，其中大多数仅停留在信息发布平台的层面。而大型房地产企业因为资金和实力相对雄厚，所以能够建立起完善的B2B或B2C型电子商务，在引入电子商务改造业务流程和供应链的实践中较为成功。本文旨在探讨一种将政府、大型房地产商、中小型房地产经纪机构和客户有机整合的新型房地产电子商务模式，让中小型房地产经纪机构也能充分利用电子商务提升服务和竞争能力。

一种水平井双侧向测井的围岩校正方法

水平井测井靠近界面时,会受到围岩的影响,且离界面距离不同,测井响应受围岩影响也不同。建立水平井钻遇地层模型,分析认为界面附近自然伽马值可较好反映离界面的距离,可利用自然伽马计算离层界面的距离;分析了离界面距离不同时水平井双侧向测井响应特征,越靠近界面,双侧向测井受围岩影响越严重,建立了水平井双侧向测井围岩校正方法。方法应用于苏里格气田苏XH水平井,双侧向围岩校正后,计算平均含气饱和度提高了2.8%,精度提高了5.21%,为水平井双侧向测井提供了一种简单有效的围岩校正方法。

Weekly scheduling models for traveling therapists

This paper presents a series of models that can be used to find weekly schedules for therapists who provide ongoing treatment to patients throughout a geographical region. In all cases, patient-appointment times and visit days are known prior to the beginning of the planning horizon. Variations in the models include single vs. multiple home bases, homogeneous vs. heterogeneous therapists, lunch break requirements, and a nonlinear cost structure for mileage reimbursement and overtime. The single home base and homogeneous therapist cases proved to be easy to solve and so were not thoroughly investigated. This left two cases of interest: the first included only lunch breaks while the second added nonlinear overtime and mileage reimbursement costs. For the first case, 40 data sets were solved, each consisting of either 15 or 20 therapists and between roughly 300 and 540 patient visits over five days. For each instance, we were able to obtain the minimum cost of providing residential healthcare services using a commercial solver. The results showed that CPU time increases more rapidly than total cost as the total number of visits grows. For the second case, which was much more difficult, it was necessary to develop heuristics to find good solutions quickly. Results for 5- through 20-therapist instances are presented and compared to the linear programming relaxation lower bounds. In the first of two parametric analyses, the tradeoff between the number of therapists on staff and the cost of providing service was examined. In the second, a similar tradeoff was explored between cost can the number of home bases used by the therapists.
