A method for the manual extraction of business rules from legacy source code

One of the main barriers to the successful migration of legacy systems is lack of information about the system to be migrated.With the complexity of modern information systems, it is rarely the case that an organisation has a complete end-to-endunderstanding of its systems, business processes and information. This is particularly true of the business rules enforced by suchsystems, which are often poorly documented (if at all) and incompletely understood by those who own, use and maintain suchsystems. These business rules must be migrated, along with the other system functionality, but this is difficult when they areburied deep within the source code of the system. In this paper, we propose a method for the discovery of business rules throughinspection of the source code of legacy systems. We also describe the results of a comprehensive evaluation exercise undertakenwithin BT, in which the method was applied to a legacy system about to undergo migration. The results of this study indicatedconsiderable success for the method in extracting valid business rules, but also highlighted some weaknesses. Most significantly,the cost of applying the method is a factor of the size and complexity of the system being analysed, and not of the number ofbusiness rules elicited. In order to address this, we propose a cut-down version of the method that can be used to produce a quickestimate of the likely yield of business rules from a program. Together, these two forms of the method aid personnel engaged insystem migration projects in making maximum use of the scarce resources are available for business rule discovery.     

正确性保证的私有过程建模方法

私有过程是构建协同业务过程基础,其正确与否对业务协同实施产生直接影响.为此,提出了一种逐步求精构建私有过程的方法.首先,定义私有过程,并将其控制流抽象为四种基本块,即顺序块、并发块、选择块及迭代块;然后,针对四种基本块提出各自的精化规则,并以此为基础提出了私有过程构建方法;最后,从理论上证明了通过该方法建立的私有过程具有工作流网特性且是正确的.通过对协同制造中供应链建模并与现有的、典型的方法对比分析,结果表明：相对已有的工作,本文方法能够更加有效地对私有过程进行建模.

扩展BPEL4WS实现基于语义的服务流程动态细化

越来越多的企业采用面向服务的架构来构建其信息基础设施,并通过执行Web服务流程来实现其业务逻辑。然而,当前作为工业界标准的服务流程建模语言BPEL4WS只能支持非常有限的运行时动态性,难以适应复杂多变的业务需求。针对这一问题,提出了在BPEL4WS及其执行引擎之上,实现基于语义的服务流程动态细化的机制——在BPEL4WS中增加目标类型的活动以及流程的语义描述；扩展现有BPEL4WS执行引擎使之能够执行带有目标活动的流程,并能够根据目标描述与流程的数据内容,在运行时为目标活动匹配与绑定子流程。     

Knowledge‐Based AOP Framework for Business Rule Aspects in Business Process

In recent years, numerous studies have identified and explored issues related to web‐service‐oriented business process specifications, such as business process execution language (BPEL). In particular, business rules are an important cross‐cutting concern that should be distinguished from business process instances. In this paper, we present a rule‐based aspect oriented programming (AOP) framework where business rule aspects contained in business processes can be effectively separated and executed. This is achieved by using a mechanism of the business rule itself at the business rule engine instead of using existing programming language‐based AOP technologies. Through some illustrative examples, this work also introduces a method by which business rule aspects, separated through an external rule engine, can be represented and evaluated. We also demonstrate how they can be dynamically woven and executed by providing an implementation example which uses two open‐source‐based products, the Mandarax rules engine and Bexee BPEL engine.

Mobile Agent Protection with Self-Modifying Code

Mobile agent is widely used in area such as parallel distributed computing for higher performance. But security issues threaten both the algorithm and data running on mobile agent system. The sensitive information within mobile agent code is inclined to be reverse engineered on a host platform. Obfuscation provides effective protection in this case with little execution time and storage size overhead. In this paper, we propose an obfuscation algorithm based on self-modifying code to prevent mobile agent code from attack at function level. We implement the algorithm and prove the efficacy of the algorithm.     

IT infrastructure Construction： Based on Competitive Advantage

Information technology （IT） infrastructure is the foundation of information sharing, storage, and processing upon which the entire business depends and it changes not only inner organizational structures but also outer competitive conditions. An IT infrastructure that possesses elements unique to a particular organization and difficult to duplicate can produce competitive advantage. To achieve this advantage, not only the inner integration of technology, personnel and business process in a firm is needed, but also a platform for electronic commerce is required. The purpose of this study is to establish the whole concept framework for IT infrastructure, based on competitive advantage, and to propose ideas about the construction of IT infrastructure system.     

Business process improvement using multi-objective optimisation

Business process redesign and improvement has become an increasingly attractive subject in the wider area of business process intelligence. Although there have been many attempts to establish a business process redesign framework, there is little work on the actual optimisation of business processes with given objectives. Furthermore, most of the attempts to optimise a business process are manual and do not involve a formal automated methodology. This paper proposes a process improvement approach for automated multi-objective optimisation of business processes. The proposed framework uses a generic business process model that is formally defined. The formal definition of business processes is necessary to ensure that the optimisation will take place in a clearly defined, repeatable and verifiable way. Multi-objectivity is expressed in terms of process cost and duration as two key objectives for any business process. The business process model is programmed and incorporated into a software optimisation platform where a selection of multi-objective optimisation algorithms can be applied to a business process design. This paper outlines a case study of business process design that is optimised by the state-of-the-art multi-objective optimisation algorithm NSGA2. The results indicate that, although business process optimisation is a highly constrained problem with fragmented search space, a number of alternative optimised business processes that meet the optimisation criteria can be produced. The paper also provides directions for future research in this area.

Low response time context awareness through extensible parameter adaptation with ORCA

Ubiquitous computing applications or widespread robots interactions execute in unforeseen environments and need to adapt to changeful available services, user needs, and variations of the environment. Context-awareness ability addresses such a need, enabling, through adaptation rules, applications to react to the perceived dynamic variations. Responses to adaptation have to be quick enough to maximize the time during which the application is coherent with its environment. Adaptation rules, associating variations of the environment to application reactions, are usually established at design time. However, in unforeseen and partially anticipated environments, we claim that adaptation rules have to be dynamically extensible to match previously unexpected variations. Our approach enables rule composition and ensures a deterministic result. We propose to use parameter adaptation to quickly respond to environmental variations and dynamic compositional adaptation to provide extensibility to the parameter adaptation. To foster even lower response times, we internalize context-awareness processing and decision into the application.

Access Control Policy Analysis and Access Denial Method for Cloud Services

Personal cloud computing is an emerging trend in the computer industry. For a sustainable service, cloud computing services must control user access. The essential business characteristics of cloud computing are payment status and service level agreement. This work proposes a novel access control method for personal cloud service business. The proposed method sets metadata, policy analysis rules, and access denying rules. Metadata define the structure of access control policies and user requirements for cloud services. The policy analysis rules are used to compare conflicts and redundancies between access control policies. The access denying rules apply policies for inhibiting inappropriate access. The ontology is a theoretical foundation of this method. In this work, ontologies for payment status, access permission, service level, and the cloud provide semantic information needed to execute rules. A scenario of personal data backup cloud service is also provided in this work. This work potentially provides cloud service providers with a convenient method of controlling user access according to changeable business and marketing strategies.
