소프트웨어 개발에 있어 XP, UP, CBD와 다른 케이스 툴과 같은 전통적 접근은 다양한 소프트웨어 컴포넌트들을 구축하기에 유용하다. 그러나 그러한 접근은 개방된 환경에 직면하여 서비스를 중점으로 설계된 것은 아니다. 서비스 지향 아키텍처(SOA)는 서비스는 애플리케이션간의 서비스라는 서로 다른 기능적 단위를 상호간 연결하는 컴포넌트 아키텍처이다. SOA는 잘 정의된 인터페이스들과 비즈니스 서비스간의 컨트랙트를 통해 비즈니스 프로세스를 통합할 수 있는 좋은 방법을 제공한다. 본 논문에서는 SOA에 기반 하여 P2P 접근 방법을 통해 비즈니스 프로세스를 모델링하는 방법을 제안한다. 또한, 전체적인 P2P 비즈니스 프로세스 모델링 시스템이 구현된다. 본 논문은 서비스에 기초하여 변경되는 엔터프라이즈의 실제를 받아들이고 보다 효율적이고 가시적인 방향으로의 엔터프라이즈 간 프로세스 통합을 제안한다.

최근 건설산업에서의 오프라인(off-line) 프로세스는 건설CALS를 포함한 수 개의 정보화기술(information technology - IT) 도구에 의해 전자화된 프로세스로 변화되고 있다. 업무프로세스를 온라인(on-line) 프로세스로 개선함에 있어, BPR은 현행 업무절차로부터 불필요하거나 추가되어야 한 프로세스를 검토한 수 있는 대표적인 방법론이다. 본 연구에서는 건설BPR을 위한 객체관계프로세스모형(Object-Related Process Model - ORPM)으로 구성된 새로운 프로세스 모형화기법을 제안하였다. 제안된 모형화기법은 주요 정보화기술인 Workflow, ERP, 건설CALS 및 업무분할체계(BBS)와의 연계가 고려되었다. 본 연구에서 제시된 ORPM은 세부 건설업무프로세스를 표현하기 위한 대표적인 모형으로서, 8개의 객체, 9개의 관계, 6개의 활동구분 등으로 구성되었다. 건설산업분야의 BPR에 관한 연구와 실무적용사례가 부족한 현실에서, 본 연구에서 제안된 모형은 건설BPR을 위한 유용한 도구가 될 수 있을 것이다.

A workflow process (or business process) management system helps to define, execute, monitor and manage workflow models deployed on a workflow-supported enterprise, and the system is compartmentalized into a modeling subsystem and an enacting subsystem, in general. The modeling subsystem's functionality is to discover and analyze workflow models via a theoretical modeling methodology like ICN, to graphically define them via a graphical representation notation like BPMN, and to systematically deploy those graphically defined models onto the enacting subsystem by transforming into their textual models represented by a standardized workflow process definition language like XPDL. Before deploying those defined workflow models, it is very important to inspect its syntactical correctness as well as its structural properness to minimize the loss of effectiveness and the depreciation of efficiency in managing the corresponding workflow models. In this paper, we are particularly interested in verifying very large-scale and massively parallel workflow models, and so we need a sophisticated analyzer to automatically analyze those specialized and complex styles of workflow models. One of the sophisticated analyzers devised in this paper is able to analyze not only the structural complexity but also the data-sequence complexity, especially. The structural complexity is based upon combinational usages of those control-structure constructs such as subprocesses, exclusive-OR, parallel-AND and iterative-LOOP primitives with preserving matched pairing and proper nesting properties, whereas the data-sequence complexity is based upon combinational usages of those relevant data repositories such as data definition sequences and data use sequences. Through the devised and implemented analyzer in this paper, we are able eventually to achieve the systematic verifications of the syntactical correctness as well as the effective validation of the structural properness on those complicate and large-scale styles of workflow models. As an experimental study, we apply the implemented analyzer to an exemplary large-scale and massively parallel workflow process model, the Large Bank Transaction Workflow Process Model, and show the structural complexity analysis results via a series of operational screens captured from the implemented analyzer.

One of the important applications for business-to-business electronic commerce is in procurement and inventory management using electronic data interchange(EDI). Using online catalogs and approved supplier lists, firms can easily create requisitions and purchasing documents. The emerging trend in EDI technology is changed from VAN(Value Added Network) based EDI to XML based EDI. This paper intends to suggest a component-based XML/EDI system using Unified Modeling Language(UML), as an application system for automobile part industry. Applying component based XML/EDI systems designed with UML methodology, we analyzed the workflow and the document on procurement process between trading partners and implemented a prototype of efficient XML/EDI system, as a surrogate of existing VAN/EDI. The result of applying object-oriented CBD(Component Based Development) technique is to minimize the risk of life cycle and facilitate the reuse of software as mentioned to limitation of information engineering methodology. It enables the interoperability with corporate legacy systems such as ERP(Enterprise Resource Planning), SCM(Supply Chain Management). This system proposes a solution to apply analysis phase and design phase in implementation of XML/EDI system. The implementation of XML/EDI system using CBD shows the ease of use in software reuse and the interoperability with corporate internal information system. The purchasing department with XML/EDI system can electronically communicate purchase orders, delivery schedules to external suppliers and interoperate with other application systems.

Abstraction applied in computer networking hides network details behind a well-defined representation by building a model that captures an essential aspect of the network system. Two current methods of representation are available, one based on graph theory, where a network node is reduced to a point in a graph, and the other the use of non-methodological iconic depictions such as human heads, walls, towers or computer racks. In this paper, we adopt an abstract representation methodology, the thinging machine (TM), proposed in software engineering to model computer networks. TM defines a single coherent network architecture and topology that is constituted from only five generic actions with two types of arrows. Without loss of generality, this paper applies TM to model the area of network monitoring in packet-mode transmission. Complex network documents are difficult to maintain and are not guaranteed to mirror actual situations. Network monitoring is constant monitoring for and alerting of malfunctions, failures, stoppages or suspicious activities in a network system. Current monitoring systems are built on ad hoc descriptions that lack systemization. The TM model of monitoring presents a theoretical foundation integrated with events and behavior descriptions. To investigate TM modeling's feasibility, we apply it to an existing computer network in a Kuwaiti enterprise to create an integrated network system that includes hardware, software and communication facilities. The final specifications point to TM modeling's viability in the computer networking field.

Artificial Intelligence (AI) technology has already penetrated deeply into our daily lives, and we live with the convenience of it anytime, anywhere, and sometimes even without us noticing it. However, because AI is imitative intelligence based on human Intelligence, it inevitably has both good and evil sides of humans, which is why ethical principles are essential. The starting point of this study is the AI principles for companies or organizations to develop products. Since the late 2010s, studies on ethics and principles of AI have been actively published. This study focused on AI principles declared by global companies currently developing various products through AI technology. So, we surveyed the AI principles of the Global 500 companies by market capitalization at a given specific time and collected the AI principles explicitly declared by 46 of them. AI analysis technology primarily analyzed this text data, especially LDA (Latent Dirichlet Allocation) topic modeling, which belongs to Machine Learning (ML) analysis technology. Then, we conducted a Delphi technique to reach a meaningful consensus by presenting the primary analysis results. We expect to provide meaningful guidelines in AI-related government policy establishment, corporate ethics declarations, and academic research, where debates on AI ethics and principles often occur recently based on the results of our study.

최근에 업무효율성 향상에 대한 요구가 정보관리기술 분야의 핵심이슈로 대두되면서 많은 기업들이 워크플로우 관리 시스템의 도입을 통한 업무프로세스 자동화에 주력해 오고 있다. 특히, 기업내부 업무프로세스 즉 워크플로우 프로세스에 대한 자동화에 이어 기업간의 업무프로세스 상호연동을 필요로 하는 비즈니스 모델이 전자상거래, 전자무역 등의 급속한 확산과 더불어 활성화되면서 새로운 형태의 워크플로우 프로세스인 기업간 글로벌 워크플로우 모델을 위한 워크플로우 관리 시스템의 확장을 필요로 하고 있다. 본 논문에서는 기업간 글로벌 워크플로우 모델을 효과적으로 지원할 수 있는 새로운 형태의 기업간 워크플로우 모델링 방법론으로서 Fragment-driven 워크플로우 모델링 방법론을 제안한다. Fragment-driven 워크플로우 모델링 방법론은 실제 조직에서 엑티비티를 수행하게 될 각 참여자가 자신의 조직에 연관된 엑티비티들만을 정의하게 한 후에 그들의 통합을 통해 하나의 기업간 글로벌 워크플로우 프로세스의 모델링을 가능하게 하는 Bottom-Up방식이다. 이 방식은 각 조직의 참여자들이 자신들의 정보만을 이용하여 모델링하는 방법이기 때문에 각 조직의 독립성을 유지하면서도 모델링 작업을 단순화시킬 수 있는 장점을 기대할 수 있다. 본 논문에서는 이러한 Fragment-driven 워크플로우 모델링 방법론의 이론적 배경과 내용을 기술하며, 이 방법론을 기반으로 하는 협업적 스림레인 워크플로우 모델링 시스템을 구현한다.

Recently, many enterprises have attempted to capitalize knowledge assets on data warehouse (DW). It has been recognized as strategic core process to create corporate competitive advantage and implement enterprise e-biz strategies. However, most approaches to represent knowledge and decision process have limits in considering various knowledge types, their relationships and continuity in knowledge formulation. In addition, they are so inclined to one side such as concept-oriented frameworks or technology-oriented ones. They lack universal and wide-ranging features. This paper presents a comprehensive methodology to accumulate knowledge capital on DW via a properly grained hypermedia model. The methodology consists of three phases: knowledge requirement elicitation, hypermedia modeling, and system implementation. A real-life case for medical DW development is presented to demonstrate the usefulness of the proposed methodology. This methodology is effective when an organization accumulates knowledge assets to put the corporate e-biz or cre-biz strategy into practice.

The operation of a networked computing system (NCS), such as Internet, can be viewed as a resource allocation problem, and can be analyzed using the techniques of mathematical modeling. We define a general NCS and translate that setup into a model of an economy. The preferences of users are taken as primitives, and servers in the network are viewed as productive firms with priority input queues. Each sewer charges a rental price for its services by priority class. We characterize optimal system allocation, and derive formulae for supporting rental prices and priority premia such that the aggregated individual user demands do not exceed optimal levels and waiting-time expectations are correct. Our economic approach has the added benefit of providing a sound basis for evaluating NCS investment alternatives, using a process analogous to free entry and exit in free-enterprise economies.
