The current international standard ISO quality management practices and process-oriented methods widely used in various internal management and supervision, but businesses in dealing with the rapidly changing external environment, information technology can bring knowledge and complexity, as well as the effective use of corporate resources can be fully and so forth, these important issues can not be resolved through the above methods. The proverb says: You can manage what can not measure. The proverb also says: You can not measure what you can not describe. Therefore, enterprises need a clear and concise method for describing their overall business operations. It is even better that this method owns the flexibility to flexible and easy to learn and other features, so as to ensure sustainable development of the business. This study investigated Service-Oriented Cable TV Customer Business Management Model (SOCTCBMM). SOCTCBMM most salient feature is a service (structure elements) to guide a behavior, resulting in structure-behavior coalescence (SBC) of effect. In other words, Service-Oriented Cable TV Customer Business Management Model uses structure view as an entry point, so the basic unit of SOCTCBMM is a service, differing from process-oriented methods which use behavior view as an entry point. This research concluded that: the SBC service-oriented approach clearly and concisely describes the overall business operations, and therefore it is the enterprise the best options, it is not an exaggeration.

<p>Cascading Web Services represent a collection of services offered in a system consisting of multiple devices and multiple interacting platform independent networks. ‘Cascading’ enables Web Services to exploit access in diverse environments without manual intervention. The aim of this thesis is to investigate how Mobile Web Services interact with multiple other Web Services by allowing the generated content to cascade. These services are demonstrated as a technical design solution, in a number of cases within the field of Learning technologies. Communication among devices is preceded using request-response commands by cascading these commands between different Web Services that are self-contained and independent on their context or state.</p><p>The system signifies a typical Service Oriented Architecture (SOA) based on a distributed system. Cascading Web Services involve multiple transport networks including Bluetooth Technology, GPRS, Wi-Fi, and Wired Networks. Whereas the protocol of this communication is to bridge Wired and Wireless networks for data transactions, specifically from a Bluetooth location-based network. A number of particular cases will be illustrated in the context of ‘educational outdoor activities’, to demonstrate how the system solution works involving users.</p>

<p>This thesis emphasizes on investigating the relationship between the quality attributes and service oriented architecture (SOA). Due to quality attributes requirements drive the design of software architecture, it is necessary to maintain the positive quality of SOA and improve the negative quality of SOA. This thesis gives an introduction to SOA, Enterprise Service Bus (ESB) and MULE. Then, it covers information on quality of systems and tactics for achieving each quality attribute. Finally, we discuss the quality of SOA in detail, and illustrate how to set up a SOA and how to improve its quality using a case of an order for supermarket.</p> / Order of supermarket

The recent advancement in computer-integrated manufacturing related technologies (e.g. internet of things, information technology and service-oriented architecture) has prompted the need for a novel effective, efficient and economical automatic identification and data collection solution for manufacturing scenario. Accurate and timely manufacturing front line information is essential to guarantee the functions and performance of enterprise information systems (EISs) deployed, and is the basis of entire information flow in enterprise. Both researchers and commercial players have made great contributions to the fields of enterprise information systems and data capturing technologies. However, real-time data processing and on-line knowledge support to seamlessly link up the EISs and shop floor front-line operations are still open to discuss. This research discusses an overall solution for manufacturing real-time field data capturing, processing and disseminating strategy in ubiquitous manufacturing environment, named Ubiquitous Manufacturing Platform (UMP). This research discusses the design and development of UMP, which is an innovative framework to integrate Auto-ID hardware devices and software services for facilitating manufacturing shop floor production management. The proposed event-driven UMP aims to enable shop floor real-time visibility and traceability, and bridge the gap between frontline operations and management level activities (e.g. planning and scheduling). On one hand, production management objectives are fulfilled through defined and configured services, and eventually carried out at shop floor operating sites with managed Auto-ID devices. On the other hand, the generated shop floor real-time field data is captured as events, which are then processed and aggregated to leveled meaningful information to satisfy various information requirements for different roles in an enterprise. UMP is expected to improve the efficiency and effectiveness of production supervision and decision making, and to reduce the production disturbances. This research has made the following achievements and contributions. Firstly, a scalable and reconfigurable infrastructure for manufacturing real-time field data capturing, processing and disseminating, named UMP, is developed based on several core technologies to achieve seamless dual-way connectivity and interoperability among enterprise application systems, shop floor, production line and workstation levels. Secondly, an innovative information processing mechanism, namely critical event model, is designed to connect the real-time field data in manufacturing processes to implied business context information. Based on this model, real-time field data is able to be organized in various abstract levels, so as to be useful for making adaptive enterprise decisions. Thirdly, a lightweight devices middleware solution named Gateway Operating System (GOS), is designed and proposed to support UMP. GOS enables a unified system interface for manufacturing companies to deploy and manage their heterogeneous Auto-ID devices. Furthermore, it allows multiple back-end manufacturing applications to share the same Auto-ID infrastructure, and shields the application systems from the implementation detail of enabling hardware devices. Fourthly, the gateway event processing procedure is presented to implement the engine for shop floor real-time field data capturing, processing and disseminating. Based on the Auto-ID infrastructure, it combines the concept of event and software agents into workflow management to realize real-time reconfigurable ubiquitous manufacturing. / published_or_final_version / Industrial and Manufacturing Systems Engineering / Doctoral / Doctor of Philosophy

Interoperability between heterogeneous software systems is an important issue to increase software reusability in the software industry. Many methods are proposed to implement interoperable systems using distributed computing infrastructures such as CORBA, HLA and SOA. Those infrastructures can provide communication channels between software systems with heterogeneous environments. SOA (Service Oriented Architecture) provides a more flexible approach to interoperability than do the others because it provides platform independence and employs platform-neutral message passing with Simple Object Access Protocol (SOAP) to communicate between a service and a client.The main contribution of this study is to design and implement an interoperable DEVS simulation environment using the SOA concept and a new construct called the DEVS namespace. The interoperable DEVS environment consists of a DEVS simulator service and an associated integrator. The DEVS simulator service provides both simulator level and model level interoperability. Moreover, using the DEVS namespace, DEVS simulator services can be interoperable with any services using the same message types.To demonstrate the utility of the proposed environment, we describe various applications of the interoperable DEVS simulation environment. The applications are drawn from real world development of automated testing environments for military information system interoperability. A radar track generation and display federation and a model negotiation web service illustrated the ability of the proposed middleware to work across platforms and languages. Its ability to support higher level semantic interoperability will be demonstrated in a testing service that can deploy model agents to provide coordinated observation of web requests of participants in simulated distributed scenarios.

Web services are widely used in banking, finance, insurance, tourism, e-business sectors and so on. Web services have emerged only recently, so the issues are typical for new technologies: ideas had arisen on technological level, and methods for modeling and development are coming only later. Existing development processes and notations such as Object-Oriented Analysis and Design (OOAD), Enterprise Architecture (EA) frameworks, and Business Process Modeling (BPM) provide us with capabilities to identify and describe appropriate architectural abstractions, but it’s not enough for realization of Service Oriented Architecture (SOA). In this work the methodology is proposed for design of stand-alone services and combining them into larger system. Proposed methodology joins main principles of Object-Oriented Analysis and Design, Enterprise Architecture frameworks, and Business Process Modeling. This methodology allows to describe service-oriented models using UML diagrams and to combine them with each other. Stages of designing stand-alone services are: business modeling, requirements analysis, identification of interfaces, analysis of interface interaction, specification of components, service model (WSDL diagram) design. Designing services systems consists of following steps: use case modeling, services identification, choreography modeling, business modeling and composite service modeling. The examples of proposed methodology for designing stand-alone services and combining... [to full text]

Different types of web resources, such as Web Services, HTTP-based APIs and websites, can be located on the web to provide various services, such as information access and online banking. Such services are the basic building blocks to compose more complex functionality that cannot be achieved by a single service. Many service-oriented applications can be composed to fulfill similar functional requirements. Among various applications, a set of services can be frequently used together to deliver a unique functionality. Such set of services are called a service composition pattern. More specifically, a service composition pattern consists of a set of services and the control flow among the services. The reuse of the service composition patterns can facilitate the composition of new applications, improve existing applications and optimize maintenance process of services. To facilitate the identification and reuse of service composition patterns, we propose an approach that mines the service composition patterns from execution logs produced by service-oriented applications during runtime. Since the execution logs can be produced by heterogeneous web resources, we propose a unified description schema to describe various web resources in order to identify functionally similar services of different types. This helps reveal complete service composition patterns. Then we identify frequently associated services using Apriori algorithm and heuristics. Finally, we recover the control flow among the services using the event graph and process mining techniques. The effectiveness of the approach is evaluated through two case studies. The result shows that the unified description schema facilitates the identification of similar services of different types and our approach can effectively identify service composition patterns. / Thesis (Master, Electrical & Computer Engineering) -- Queen's University, 2010-09-29 18:08:07.55
