计算机物流信息管理系统设计及应用

<正>0.引言实现物流信息管理,就是实现对物流信息的全面收集、有效整理、稳定存储以及传播利用。当前,物流信息管理方面仍存在很多不足,为此,本文设计了计算机物流信息管理系统,将系统硬件框架进行优化,并在此基础上对系统软件进行优化设计,在分析系统需求的基础上,划分需求功能,按功能分区将数据信息建立相应的管理模块,包括企业前台信息管理模块、用户信息管理模块以及企业后台信息管理模块三类,同时,建立善物流信息数据库,完善数据库信息表,完成系统的设计。通过实验测试,验证本文设计系统的使用性能,实际结果表明,本文设计的系统能够有效便捷地进行物流信息的管理,提高了信息管理的操作简易度,在提高物流企业信息管理效率方面具备极高的有效性。

An exact solution approach for vehicle routing and scheduling problems with soft time windows

A new column generation based exact optimization approach for the vehicle routing and scheduling problem with semi soft time windows (VRPSSTW) is presented. Elementary shortest path problem with resource constraints and late arrival penalties is solved as a subproblem, which rises from the Dantzig–Wolfe decomposition method. Exact solutions of VRPSSTW and hard time windows variant are compared on Solomon’s benchmark instances as well as on an instance based on Tokyo road network. It was found that the VRPSSTW solution results in fewer routes thus overall costs are reduced and late arrival penalties contribute only a small fraction to total cost.     

Planning towing processes at airports more efficiently

This paper addresses the towing process of airplanes as part of the turnaround process. We introduce a VRP based MIP model which assigns different types of towing tractors to jobs with specified service time windows. The objective function minimizes operating costs subject to operational restrictions such as technical compatibility of tractor types with plane types. Our modeling approach allows for multiple depots as well as multiple trips. To solve the model we develop a column generation heuristic. Computational results show the superior behavior of the proposed heuristic compared to the original MIP formulation solved with CPLEX. In a case study we derive insights which support schedulers in their daily work. For this, we identify cost drivers and evaluate the efficiency of manual schedules in retrospect.

Ride service outsourcing for profit maximization

Transportation service subcontracting is becoming an effective means of business for many leading carriers to maintain their market dominance and profitability. This research is based on an outsourcing practice in one of the few largest limousine fleet companies in the US, whose (mostly advance) demand for services often exceeds its capacity. We develop a model for ride service outsourcing. A column generation method is proposed. The outsourcing decision is made simultaneously with pre-scheduling of in-house ride services as well as staffing. Test with services data indicates that the developed method dramatically improves the carrier’s outsourcing decision.     

Hungry for Growth? Small and Medium‐sized Tourism Enterprise (SMTE) Business Ambitions,Knowledge Acquisition and Industry Engagement

Differences are identified between the preferred information and learning channels of small and medium‐sized tourism enterprise (SMTE) proprietors, who have an interest in business operations (growers) or who have relatively less interest (lifestylers). Lifestylers sign up frequently to tourism industry associations, whereas growers have a tendency to join generic business groupings. The most common information for both groups is marketing related, and intensive use is made of online information to support day‐to‐day business operations. In aggregate, SMTE proprietors are avid information seekers, attaching importance to the advice provided from experienced and trusted sources. Growers proactively gather information about general management as well as tourism‐specific knowledge. Adopting a ‘one size fits all’ approach to providing information for the SMTE sector is unlikely to be effective. Copyright © 2012 John Wiley & Sons, Ltd.

A new approach to travel information sources and travel behaviour based on cognitive dissonance theory

This study examines the influences of en route information on travel behaviours, based on cognitive dissonance theory, which explains that selective exposure to new information leads to the presence of dissonance. Fifteen travel activities were identified from the related literature to measure levels of unplanned travel behaviours. Moreover, two types of information sources used during trips were tested to evaluate the degree of dissonance in accordance with new information provided to travellers while on vacation. The results indicated that during trips, those who use information technology change their intended behaviours, while those who use ‘traditional’ information sources actualize their intended behaviours. In line with cognitive dissonance theory, information technology is viewed as dissonance-increasing information, while traditional information sources used during trips are considered consonance-increasing information.     

Providing packages of relevant ATM information: An ontology-based approach

ATM information providers publish reports and notifications of different types using standardized information exchange models. For a typical information user, e.g., an aircraft pilot, only a fraction of the published information is relevant for a particular task. Filtering out irrelevant information from different information sources is in itself a challenging task, yet it is only a first step in providing relevant information, the challenges concerning maintenance, auditability, availability, integration, comprehensibility, and traceability. This paper presents the Semantic Container approach, which employs ontology-based faceted information filtering and allows for the packaging of filtered information and associated metadata in semantic containers, thus facilitating reuse of filtered information at different levels. The paper formally defines an abstract model of ontology-based information filtering and the structure of semantic containers, their composition, versioning, discovery, and replicated physical allocation. The paper further discusses different usage scenarios, the role of semantic containers in SWIM, an architecture for a semantic container management system, as well as a proof-of-concept prototype. Finally the paper discusses a blockchain-based notary service to realize tamper-proof version histories for semantic containers.     

情报信息主导警务战略下基层民警信息素养的提高

情报信息工作是公安工作的重要内容，公安机关要履行三大政治和社会责任，实现全方位服务人民的宗旨，就必须构建情报信息主导警务战略机制，切实把情报信息工作置于公安工作的基础性、先导性位置，以情报信息引导实战，指导防范和打击犯罪。然而，当前基层公安机关存在的思想认识不到位、信息系统分散、信息化素质不高、信息研发滞后等问题，严重制约了公安工作的深入开展，因而有必要对基层公安民警的信息素养进一步加强和提高。
