Resource virtualization and service selection in cloud logistics

Cloud computing and Internet of Things have promoted a new logistics service mode, i.e., the cloud logistics mode. This work studies the resource virtualization and service encapsulation of a logistics center, and focuses on the technologies of resource expression and service encapsulation. After the resources of a logistics center are encapsulated in web services, how to find the “best” concrete web service among many is a critically important issue. This work considers service selection as an optimization problem and establishes a Particle Swarm Optimization (PSO)-based web service selection model with quality of service (QoS) constraints. It can be used to address the horizontal adaptation issues from the composite web services. The feasibility and effectiveness of the model are verified by several experiments.

Service Encapsulation-Based Model for Smart Campus

Currently, many universities are equipping information facilities, the informatization construction on which the basis of Internet and the information service in the campus begins. The smart campus is an advanced stage in the construction of campus informatization, which can make the daily life in a campus more convenient. This paper analyzes the current construction of campus informatization, proposes an intelligent campus space model, and discusses key technologies based on the idea of object-oriented technique and service encapsulation. This model can support most campus activities, such as access control, e-commerce, and e-services.

Electronic Warfare Simulation-based on Service Oriented Architecture

The realisation of service oriented architecture (SOA) is embodied in the accomplishments of various simulation applicable functions in the form of service encapsulation and the interconnection and interoperation of services. In this paper, an electronic warfare (EW) simulation is structured to SOA and achieved the effect of dynamic sharing and reusability. As a proof of concept, a radar electronic support (ES) simulator, which intercepts and classifies radar signals is designed and explained in this paper.

Study on 4PL Information Platform based on Web Services

The forth party logistics (4PL) information Platform is an information platform for comprehensive supply chain solutions for the customers in modern logistics environment. This paper put forward a web services based information platform for 4PL based on the analysis of information management requirements for regional logistics management and operation, and analysis the operation process of 4PL information platform. Furthermore, some key enable technologies supporting for 4PL information platform are studied, which including Web services encapsulation technology for logistics services and constructing technology for logistics services chain. The realization of the information platform provided an information operation platform for regional logistics operation and is validated in the 4PL information platform construction in Ningbo City.

Business processes oriented heterogeneous systems integration platform for networked enterprises

Supply chains, dynamic alliances, e-business, extended enterprises, and virtual organizations are typical networked enterprises which are formed based on partner companies’ core competencies. Different partners have different infrastructures; the interoperability among heterogeneous systems is the solid foundation for the networked enterprise to work seamlessly and effectively. Due to the distributed and heterogeneous characteristics of different partner companies, it is a big challenge to implement a satisfying and cost effective solution in the networked enterprise. Aiming at the problems of system integration and cross-system interoperability, Service-Oriented Architecture (SOA) provides a new integration pattern and relative system infrastructure. The key for the development and implementation of SOA is services encapsulation and orchestration of applications through certain mechanism to operate a complex business. However, cross infrastructures services access protection and relative services orchestration are still the bottleneck for the SOA implementation. This paper develops a business processes oriented heterogeneous systems integration platform with relative methodology for networked enterprises integration. The platform is a space distributed and management centralized platform for networked enterprises. The service access agent (SAA) mechanism is developed to realize cross-domains identity authentication, service authorization, and information transmission security. Every Web service or SAA in the platform has a unique ID. The interoperating process only relies on IDs, which endows the platform with a loose coupling feature. Aiming at service orchestration, a graphic service process modelling method is developed, with which the developed process model can link atom Web services and form a complex service. The Java based service orchestration tool provides an ESB (Enterprise Service Bus) independent service orchestration and deployment. Those services that are results of orchestration can be orchestrated as an atom service in another orchestrating process. Thus, the platform can support orchestration decomposition. The structure approach of the business process modelling based platform implementation is developed, which provides a guideline for platform installation, services modelling, service encapsulation, service orchestration, and service deployment. Two cases are provided to illustrate the usage of the platform in industries. The development of this platform is an open source project.

At last, the system is used to analyze the impact factors of online consumption behavior.

An integrated and collaborative approach for complex product development in distributed heterogeneous environment

Multidisciplinary collaborative modeling and simulation is an effective approach to verify the dynamic behaviour of a complex product such as an aerospace vehicle or a locomotive. The design environment of such products must cater for the requirement for geographical distribution and structural heterogeneity in the modern industrial context. The focus of our research is a solution for such a collaborative modeling and simulation environment. Our approach is to utilize the IEEE standard High Level Architecture for distributed simultaneous simulation execution and management. At the same time, Web services technology is employed to deploy and integrate functional models for the simulation. The method for model description in this framework is proposed. The techniques for simulation execution and service encapsulation are discussed. A prototype system is implemented and a case study of locomotive tilting component design is executed. We find that both High Level Architecture and Web services have their expertise for collaborative simulation and the integration of these two technologies does achieve better interoperability and reusability among heterogeneous simulation components in a distributed environment. The new approach has considerable promise for the efficient and successful complex product design.

Semantic-Based Medical Information Integration Scheme for Medical Image Grid

A semantic-based information integration scheme for MedImGrid (medical image grid) is presented, which creates parent-ontology (HL7-RIM ontology) based on HL7-RIM (health level 7 referenced information model), and adopts hybrid means to construct the hierarchical structure of MedImGrid global and local ontologies. The HL7 (health level 7) gird middleware is developed based on Agent and middleware technology, which gives the semantic parsing capability to HL7 intelligent Agent to support grid service encapsulation and uniform access of heterogeneous data sources. The interrelations of data modes at ontology layer are denoted with ontology tag and used to support the semantic parsing and mapping between different medical data sources referring to MedImGrid ontologies. MedImGrid prototype is based on CGSP2 (China grid support platform v2.0) and adopts global and local semantic mapping loosely coupled means, and its special layered structure makes resource sharing and matching across systems and hospitals more efficient.
