Such complexity requires a large amount of data to be treated by the three levels of process control: field devices, control systems and management softwares. To use data effectively in each one of these levels is extremely important to industry. Many of today s industrial computer systems consist of distributed software systems written in a wide variety of programming languages and developed for specific platforms, so, even more companies apply a significant investment to maintain or even re-write their systems for different platforms. Furthermore, it is rare that a software system works in complete isolation. In industrial automation is common that, software had to interact with other systems on different machines and even written in different languages. Thus, interoperability is not just a long-term challenge, but also a current context requirement of industrial software production. This work aims to propose a middleware solution for communication over web service and presents an user case applying the solution developed to an integrated system for industrial data capture , allowing such data to be available simplified and platformindependent across the network / O controle de processos industriais t?m se tornado cada vez mais complexo devido ? diversidade de equipamentos de ch?o-de-f?brica, exig?ncia na qualidade e concorr?ncia de mercado. Tal complexidade exige que, uma grande quantidade de dados seja tratada pelos tr?s n?veis de controle de processo: dispositivos de campo, sistemas de controle e software para gerenciamento. Utilizar de forma efetiva os dados presentes em cada um desses n?veis ? de fundamental import?ncia para ind?stria. Muitos dos sistemas computacionais industriais de hoje s?o compostos de sistemas distribu?dos de software, escritos em uma grande variedade de linguagens de programa??o e desenvolvidos para plataformas espec?ficas. Desta forma, cada vez mais, pequenas e grandes empresas aplicam um investimento significativo para manter ou at? mesmo reescrever seus sistemas para diferentes plataformas. Al?m disso, ? raro que um sistema de software seja executado em completo isolamento. Na ?rea de automa??o industrial ? comum que sistemas de software interajam com outros sistemas em diferentes m?quinas e at? mesmo escritos em diferentes linguagens. Tendo isto em vista, interoperabilidade n?o ? apenas um desafio a longo prazo, mas tamb?m uma exig?ncia do contexto atual de produ??o de softwares industriais. Este trabalho visa propor uma solu??o de middleware para comunica??o de aplica??es via web service, al?m de apresentar um estudo de caso aplicando a solu??o desenvolvida a um sistema integrado para captura de dados industriais, permitindo assim que tais dados sejam disponibilizados de maneira simplificada e independente de plataforma atrav?s da rede

The purposes of this study were to design and develop the web service for fixed asset tracking and stock taking. Both theoretical and practical concepts were examined in order to apply them during significant part of service's life cycle covered in this thesis, from the very first analyses to the first production release. Primary goal of this study was to design the service and get it ready for the basic usage. Secondary goal was to document the process of designing and developing the service. Involved methods, practices and technologies were described. These goals were achieved using analytical methods and executive skills. In addition to development of web service itself, most important contributions of this thesis include supplying an in-depth study of web service design and development structured as a step-by-step tutorial.

Seleção de serviços em composições distribuídas considera principalmente a qualidade de serviço que atenda requisitos estabelecidos pelo usuário, como por exemplo, preço. No entanto, problemas relacionados a execução de composições de serviços podem ocorrer quando não se considera aspectos relacionados à rede e ao hardware, que afetam diretamente o desempenho da composição. Esse problema se agrava em composições coreografadas, pois a característica descentralizada requer um maior esforço para que essas informações possam ser consideradas em uma perspectiva global. Dessa forma, apesar da descentralização apresentar vantagens, é necessário que requisitos de qualidade de serviço da composição também sejam considerados em coreografias de serviços web para que a escolha de serviços para desempenhar um papel leve em consideração parâmetros importantes que podem afetar no desempenho da composição. Este trabalho apresenta um mecanismo, implementado sobre o framework OpenKnowledge, para selecionar serviços web em ambientes coreografados considerando primeiramente estimativas de atraso, taxa de perda e por fim considera a utilização de outros parâmetros, como utilização de CPU. Os primeiros experimentos em diferentes cenários de rede confirmaram as vantagens da proposta em relação a um seletor de serviços que ignora aspectos relacionados com a rede. Obteve-se ganhos de 20 a 97% no que diz respeito ao tempo total da execução da coreografia. Em seguida, experimentos inserindo utilização de CPU na escolha dos serviços confirmaram as vantagens de utilização de diferentes parâmetros para seleção de serviços em coreografias. / Selection of services in distributed compositions mainly considers the quality of service that meets requirements set by the user, such as price. However, problems related to the execution of service compositions may occur when aspects related to network and hardware, which directly affect the performance of the composition, are not taken in consideration. This problem is aggravated in choreographed compositions because the decentralized feature requires a greater effort so that this information may be considered in a global perspective. Thus, despite the decentralization advantages, it is necessary that the service quality requirements of the composition may also be considered in the choreography of web services so that the choice of services may play a role that takes into account important parameters, which can affect the performance of the composition. This dissertation presents a mechanism, implemented on the OpenKnowledge framework, to select web services in choreographed environments. First, considering delay estimates, loss rate and finally the use of other parameters, such as CPU utilization. The first experiments on different network scenarios confirmed the proposal advantages in relation to a selection mechanism that bypasses aspects of the network. It was obtained gains from 20% to 97% considering the total time of execution of the choreography. Then, experiments inserting CPU utilization in the choice of services confirmed the advantages of using different parameters for selection of services in choreography.

The practice of composing web services has received an increasing interest with the emerging application development architecture called Service Oriented Architecture (SOA). A web service composition can be done either manually or (semi-) automatically. Doing composition (semi-) automatically minimizes runtime problems that arise due to dynamic nature of runtime environments. However, the implementation of (semi-) automatic composition demands for the automation of a process model or a composition plan generation process. In addition, creating a composite service or applications from component services, that are developed and meant to work independently, causes unavoidable dependencies among the services involved. Consequently, in a composite service development, understanding, analyzing and tracking of such dependencies becomes important. This thesis views the process model generation sub-task of a service composition as a service dependency identifification and analysis problem. In this thesis, we propose a dependency based automatic process model generation methods. For this purpose, the following issues are explored. First, a top layer architecture with a composition engine is developed. The architecture gives a complete picture of dependency based automatic service composition. Second, the process model generation sub-task is formulated as a service dependency identification and analysis problem. Third, a two-stepped method for automatic process model generation, given a set of candidate web service descriptions, is proposed. The first step of the proposed approach deals with the identifification of potential direct and indirect dependencies between abstract services. The direct dependency extraction is done by assuming a semantic I/O matching of service parameters. The extraction of indirect dependency from direct dependency is done using a recursive algorithm derived from the transitive closure property. Alternatively the Warshall algorithm is used. The second step of the proposed approach deals with analysis of dependency information and generation of process model (PM) automatically. To execute this step, we propose two approaches: matrix based and graph based approaches. The matrix based approach utilizes both direct and indirect dependencies. This approach represents dependencies using matrix and takes advantages of a sorting algorithm. The matrix representation facilitates a simplistic mathematical dependency analysis for generating important indicators during automatic process model creation. The process model is generated using a sorting algorithm that uses the analysis result obtained from the dependency matrix as sorting criterion. The graph based approach uses only direct dependency among candidate services. As its name indicates, in this approach the extracted I/O dependencies are represented using a directed graph. A modifified topological sorting algorithm is used for generating a process model that shows the execution order of candidate services. Both of the proposed approaches (matrix and graph based approaches) recognize the existence of cyclic dependencies and provide ways of dealing with them. The resulting process model or composition plan from both approaches has a sequential, concurrent and loop control flows. Finally, the performance of the proposed approaches is studied theoretically as well as experimentally. For the experimental validation and evaluation purpose, the approaches are implemented in a prototype that facilitates the validation and evaluation of the approaches at a larger scale. An extensive experimental performance evaluation is done fifirst on each proposed approach. The two approaches are then compared and their pros and cons under difffferent scenarios are assessed.

Model-driven development has been considered to be the hope of improving software productivity significantly. However, it has not been achieved even after many years of research and application. Models are only and still used at the analysis and design stage, furthermore, models gradually deviate from system implementation. The thesis integrates domain-specific modelling and web service techniques with model-driven development and proposes a unified approach, SODSMI (Service Oriented executable Domain-Specific Modelling and Implementation), to build the executable domain-specific model and to achieve the target of model-driven development. The approach is organised by domain space at architectural level which is the elementary unit of the domain-specific modelling and implementation framework. The research of SODSMI is made up of three main parts: Firstly, xDSM (eXecutable Domain-Specific Model) is proposed as the core construction for domain-specific modelling. Behaviour scenario is adopted to build the meta-modelling framework for xDSM. Secondly, XDML language (eXecutable Domain-specific Meta-modelling Language) is designed to describe the xDSM meta-model and its application model. Thirdly, DSMEI (Domain-Specific Model Execution Infrastructure) is designed as the execution environment for xDSM. Web services are adopted as the implementation entities mapping to core functions of xDSM so as to achieve the service-oriented domain-specific application. The thesis embodies the core value of model and provides a feasible approach to achieve real model-driven development from modelling to system implementation which makes domain-specific software development and reuse coming true.

Web services provide organizations with a powerful infrastructure by which information and products may be distributed, but the task of supporting Web service systems can be difficult due to the complex nature of environment configuration and operation. Tools are needed to monitor and analyze such Enterprise environments so that appropriate engineering, quality control, or business activities can be pursued. This investigation resulted in the development of a software development kit, the WSLogA Framework, which is inspired by the vision of Cruz et al. (2003, 2004). The WSLogA Framework provides distributed Enterprise systems with a platform for comprehensive information capture and environment management. Five component groups are intended for employment to enable integrated workflows addressing monitoring and response activities, but these components may also be used individually to facilitate the phased integration of the WSLogA Framework into existing environments. The WSLogA Framework's design is portable across technology platforms (e.g., Java and .NET) and a variety of technologies may be substituted for the provided implementations to address unique system architectures. The WSLogA Framework supersedes existing logging and monitoring solutions in terms of both capability and intent. Applications based on the WSLogA Framework have an internal, real-time view of their operation and may adjust their environment based on the information provided by events related to their or system activities. The WSLogA Framework is intended as a software development kit around which system functionality may be organized and implemented, which makes the WSLogA Framework an architectural peer or complement to traditional application frameworks such as Spring's Web module. WSLogA Framework based systems should be envisioned as information appliance elements rather than traditionally scoped applications or services.

摘要 財政部於民國90年11月通過金融控股公司法，此法鼓勵了金融相關產業(證券、銀行、保險、基金等業務)朝向業務整合，擴張金融版圖方向努力。如此大規模的金融經營型態調整，不僅是金融體機構的整併，尚得藉由資訊系統的整合以發揮其最大效用。隨著網路人口的增加，Charles Schwab由網路下單服務所獲得的利益，日漸吸引金融業者的網路金融投資。在經濟衰退、失業率漸增、微利率的時代，民眾在理財上也就逐漸投注更多心力。 有鑒於以上的發展，本研究乃著手收集相關文獻，整理分析相關知識作為研究基礎，利用具跨平台特性Java為開發工具且以銀行公會制定之交易訊息格式標準做為溝通的基礎，選擇以Web Service SOA作為系統模型，提出本研究的雛型架構，並實作雛型系統以驗證此架構的可行性。 綜合本研究最大成果在於：(1)參考實際金融理財服務需求，建構鬆散性結構的金融服務。(2)透過具延展性、獨立性及可移植性平台做異質性的資訊系統整合。(3)提供用戶自行設定或是組合客製化服務，協助用戶輕鬆理財。 為求本研究能發揮最大的貢獻，期望以下議題能有合適解決方案：(1)線上網路交易的付款機制能獲得網路大眾最大的信任。(2)金融產業結盟，以提供使用者最多選擇及理財整合。(3)政府長久規劃以整合現有金融資源，提升整體產業競爭力，邁向國際化。 關鍵字：XML、Web Service、SOA、資訊系統整合、金融控股、理財 / Abstract The Ministry of finance enacted the Financial Holding Company Act in November 2001. The law encourages relevant financial industries, such as securities, banks, insurance, funds, and so on, in order to integrate business and expand financial territories. Such large-scale adjustment of financial management patterns indicates the incorporation of financial institutions, and it effectively develops itself to the most through the integration of information systems. With the increase of Internet population, Charles Schwab gradually attracts the financial investment on the Internet as a result of the benefits gained from the Internet service. In the era of economic recession, high unemployment rates and low interest rates, the public gradually put in more efforts in managing finances. As a result of the above-mentioned development, this research aims to collect relevant literature, and to analyze relevant background knowledge as the research foundation. The trans-platform Java will be adopted as the development tool, and the Message Format Specification of the business transactions established by the Association of Banks will be regarded as the foundation of communication. Moreover, Web Service SOA will be chosen as the system model, and the miniature structure of this research will be proposed. Finally, the miniature system will be practically established in order to test and verify the feasibility of this structure. The largest outcome of this research lies in: (1) the consultation of the service requirement in practical financial management in order to construct the financial service with loose structures, (2) the establishment of heterogeneity in the integration of information systems though the expanded, independent, and transplantable platform, and (3) the supply of the service on subscribers’ self-setup or the combination with customization in order to assist them in managing finances easily. In order to make the most contribution out of this research, it is hoped that the following issues can have appropriate solutions: (1) the payment mechanism in on-line business transactions can gain the public’s trust and confidence, (2) financial industries can form an alliance to provide users with the most choices and integration of financial management, and (3) the government plans to integrate the available financial resources for a long time to promote the competitiveness of the overall industries toward internationalization.

According to current development of internet technology, remote control over the internet becomes a heated discussed topic. Some recent technologies such as Service-Oriented Architecture (SOA), web service and ontology offer great opportunity for remote control over the internet and a lot of research has been done into this topic. However, there are still many challenges in architecture design and dynamic user interface generation. Architectures in this research field lack clear description of controlled machine model as well as related knowledge support. Also, there is little system support further control service development. There is little research on web user interface design for remote control system over the internet. The design of web user interface has the challenge of overcoming the limitations of web technology to satisfactorily support different machines, users and control process requirements. This work overcomes the limitations on architecture by offering a SOA based design which allows both multiple users and distributed machine access. The system applies a machine model for the description of the machine structure and functions, which help the system to reason about machine components and their relationships with instructions. With a web service based design, different machines can be connected via the system and execute user commands. Using semantic description and ontology based methods the system can automatically retrieve machine information and generate the structure and function descriptions for different machines. Moreover, the system provides services which can support further development in remote control services. The proposed architecture improves on former designs, and offers a flexible architecture for remote control services over the internet. An intelligent web user interface is also introduced in this work. The design separates the interface data structure from the data representation. Supported by the remote control service development environment, the user interface could adapt to the control sessions. Semantic descriptions are used to describe the page data structure, session context as well as control command. Therefore, control page content can be adapted by the computer to real time control session. At the same time, a session dependent navigation is designed to resolve the problem of changeable requirements for multiple-machine web user interface. With a message driven model and a session dependent semantic data structure, the required machine data can be analysed by the system and categorised according to user s requirements. Compare with other designs, this service offers a method for web user interface generation for different machines, users and can adapt to different control processes. The design is demonstrated in five evaluation scenarios aimed at testing different aspects of the system. Evaluation demonstrates the design proposed in this thesis is feasible. It also shows the design can be applied to different areas and adapted to different control related requirements well.
