Recently, the off-line processes in the construction industry are being changed to the electronic processes by several information technology (IT) tools including CALS. To improve the business processes to on-line processes, the business process reengineering (BPR) is a representative methodology for reviewing unnecessary and additional processes from the established business procedure. This study suggests a new process modeling method for construction BPR (CBPR) that consists of object-related process model (ORPM). In suggested modeling method, the connection with IT tools such as Workflow, enterprise resource planning (ERP), construction CALS, and business breakdown structure (BBS) was considered. The ORPM in the study is the main model for representing the detailed construction processes. It consists of nine relationship and six diagrams to represent the relationship between construction activities and the direction within the process model. Those models suggested from this study can be a useful tool for the CBPR because the researches and the practical applications related to the BPR of construction project are insufficient in our construction industry.

기업 업무의 절차와 규모가 복잡해지고 증가함에 따라 한 사람이 기업의 모든 업무 프로세스를 모델링하고 관리하는 것이 어려워지고 있다. 기존의 Workflow 모델링 방식은 프로세스 정의를 한 명(또는 소수)의 디자이너가 맡아 왔다. 그러나 스윔레인 같은 롤 기반의 프로세스 모델링은 각 롤에 해당하는 디자이너 그룹이 프로세스를 정의하기 때문에 모델링 작업을 단순화 시킬 수 있다. 본 논문에서는 워크플로우 모델링 방식과 다른 역할 기반의 스윔레인 모델링을 바탕으로 그룹웨어기술을 접목 시켜 기업의 업무 프로세스를 보다 효율적으로 정의할 수 있는 실시간 협업 지원 협동 스윔레인 워크플로우 모델링 시스템 아키텍처를 제시한다. 이벤트 방식의 화면 처리는 네트워크 트래픽 및 오버 헤드를 감소 시킬 수 있다. 또한 분리된 어플리케이션이 비동기적으로 신뢰성 있게 통신할 수 있도록 메시징 시스템을 도입하고, 협업간 투명성(Transparency)을 보장하는 가상 협업 서버 구조를 살펴 볼 것이다. 이러한 것들은 향후 분산환경으로의 발판을 이를 수 있다.

A workflow management system is a software system to assist designing processes, controlling and managing the execution of the designed processes. One emerging trend in many recent information systems is the provision of process management functions. In this paper, we propose a method of designing processes for automatic process execution directly from process modeling. First of all, the concept of block is presented which is to define a nested process model. A block is the minimum unit that can specify the relationships of process components, i.e., tasks. A general process can be defined by a combination of the blocks defined in this paper. An algorithm is developed to transform a general flat process model into a nested model. We identify basic types of blocks and build ECA (Event-Condition-Action) rules for each of the basic types. This allows us to automate the execution of the process model by using the active features of active databases.

The patient's waiting time and length of stay have been reported as a factor decreasing their satisfaction in the hospital, especially in developing countries. This paper focuses on modeling hospital's outpatient department workflow in a developing country and optimizing the patient waiting time as well as total length of stay. By using discrete-event simulation, many alternative scenarios have raised, such as adding more working time, altering human resources, and adjusting the staff's responsibility, those scenarios will be examined to explore better settings for the hospital. The results show that possible to achieve a 9.6% reduction in patient total length of stay and it could be accomplished without adding more resources to the hospital.

This paper proposes a compact eAI framework for the integration of various types of applications deployed on different platforms in the Internet. The applications are connected and invoked to achieve a business goal by the coordination of the workflow system in the framework. for the construction of the framework, five sub-modules are elicited and the functions and roles of each module are defined. The elicited five sub-modules include business process modeling tool, eAI platform, business processes transform module, UDDI connection module, and workflow system. In the framework, intra and inter organizational applications can be integrated together across firewalls. In this paper, the extension of a workflow system to implement the framework is also described in detail and the usefulness of the framework is ascertained by implementing an application process within the framework. A full-fledged eAI solution can be constructed by gradually adding supplementary functions within this framework.

As a computerized application for controlling enterprise processes, BPM(Business Process Management) has been received such concerns that many solution vendors developed their own process definition and storage methods. The fact causes the needs of process modeling standards for process model exchange and at the same time, requires the appropriate methodology for adopting the global standards. In this paper, we propose a transformation methodology of BPMN-based file into XMI(XML Metadata Interchange)-based neutral file format. We devised translation templates for 21 workflow patterns, and compared the results with BPEL4WS(Business Process Execution Language for Web Services) translation. As a result, our XMI transformation model enables more complete translation of process model in comparison with existing model, and thus can be practically utilized to the BPM vendors adopting BPMN standards.

Increasing numbers of value added chemicals are being produced using microbial fermentation strategies. Computational modeling and simulation of microbial metabolism is rapidly becoming an enabling technology that is driving a new paradigm to accelerate the bioprocess development cycle. In particular, constraint-based modeling and the development of genome-scale models of industrial microbes are finding increasing utility across many phases of the bioprocess development workflow. Herein, we review and discuss the requirements and trends in the industrial application of this technology as we build toward integrated computational/experimental platforms for bioprocess engineering. Specifically we cover the following topics: (1) genome-scale models as genetically and biochemically consistent representations of metabolic networks; (2) the ability of these models to predict, assess, and interpret metabolic physiology and flux states of metabolism; (3) the model-guided integrative analysis of high throughput 'omics' data; (4) the reconciliation and analysis of on- and off-line fermentation data as well as flux tracing data; (5) model-aided strain design strategies and the integration of calculated biotransformation routes; and (6) control and optimization of the fermentation processes. Collectively, constraint-based modeling strategies are impacting the iterative characterization of metabolic flux states throughout the bioprocess development cycle, while also driving metabolic engineering strategies and fermentation optimization.

Among numerous chemicals used globally, the number of emerging contaminants is increasing. Numerical modeling for contaminant fate and transport in the subsurface is critical to evaluate environmental and health risk. In general, such models require physicochemical properties of contaminants as input values, which can be found in numerous chemical databases (DB). However, there exist lack of information specific to recently emerging contaminants, which requires estimation of physicochemical properties using regression programs. The purpose of the study is to introduce the workflow for identifying physicochemical properties of potential contaminants utilizing numerous chemical DBs, which frequently lists up potential contaminants for estimating chemical behavior. In this review paper, details of several chemical DBs such as KISChem, TOXNET, etc. and regression programs including EPI $Suite^{TM}$, ChemAxon, etc. were summarized and also benefit of using such DBs were explained. Finally, a few examples were introduced to estimate predominant phase, removal ratio, partitioning, and eco-toxicities by searching or regressing physicochemical properties.

본 논문의 연구방향은 객체지향방법론을 이용하여 PDM에서의 워크플로우를 재설계하는 것이다. 기존의 방법론들은 워크플로우 엔진과 작업자 사이의 흐름에 중점을 두었으나 본 논문에서는 프로세스와 작업에 중점을 두고 이를 각각의 객체로 설계하는 방안을 연구하고자 한다. 시스템의 설계를 위하여 Rumbaugh의 OMT(Object Modeling Technique) 방법론을 기본모델링 방법론으로 사용한다. 연구내용은 object model을 통한 정적 구조 설계, dynamic model을 이용한 시간에 따른 동적 구조 설계, 그리고 functional model에서의 데이터의 전이 및 시스템간의 연계의 설계이다. 특히 object model에서의 작업설계 및 dynamic model에서의 상태변화에 중점을 두고 DCOM(Distributed Component Object Model)을 사용하여 작업(task)을 중심으로 한 분산환경을 구현한다.
