It is a very difficult task to establish a collaborative procedure in a new business that requires multilateral collaboration or to revise the regulation by analyzing and proving objectively the problems in the collaborative process conducted already by multilateral collaboration. In this paper, we proposed an optimization model for collaborative process to establish the operation procedure between collaborative parties using PERT/CPM network diagram which allows us to calculate the processing time. In order to verify the effectiveness and usefulness of our model for the collaboration process optimization developed in this study, we applied the developed collaborative procedure to student selection of the work-and-study-in-parallel course associated with a degree executed by Ministry of Employment and Labor. This study can be useful not only for newly establishing or reconfiguring collaborative procedures but also for standardizing the business procedures for building information systems between collaborative organizations.

This paper presents process model to accomplish traffic engineering in Internet. The process model consists of 4 stages. The first stage is the formulation of a control policy dominated network operation. The second stage is the observation of the network state through a set or monitoring functions. The third stage is the characterization or traffic and analysis or the network state. The final stage is the optimization of network performance. the four stages of the process model defined above are iterated.

Recently, the aim of cold storage warehouse is not only to provide preservation of the quality of perishable foods but also to use state-of-the-art information systems to rapidly move products across the cold chain. An RFID (Radio Frequency Identification) is an automatic identification method that detects signals from mobile objects, and tracks and traces movement of the objects. RFID can be used to turn a cold storage warehouses into a real-time system. In this paper, we develop an cold storage management system to support the optimized business processes with RFID system. First of all, business processes in the cold storage warehouse are analyzed. Then design factors which should be considered for incorporating RFID are defined. Design values which set to the design factors can be extracted from using RFID deployment simulator. as a result, the design values make RFID to be efficiently integrated to existing business processes.

In this paper, it is covered in detail the process of generating structural alternatives with geometry change and its optimization by StrAuto. The main roof structure of the Exhibition Center is modelled parametrically and the optimal alt is derived by observing volume changes according to geometry change of main roof truss. Existing studies performed optimization process through sections and properties due to the limitations of shape change, but this study have meaning of performing the optimization with geometry changes which is the most critical skills of StrAuto. By the process of securing a sufficient margin by geometry changes and reducing volume with the optimization of sections, despite of a partial optimization of large space structure, it could be reduced by 11.7% of the total volume.

Nowadays, most enterprises have introduced both EA methodology to optimize an entire enterprise and CBD methodology to improve a software reusability. The Korea Government not only have developed many EA guiding products such as EA framework, Reference Model, Guideline, etc. but also have instituted a law to optimize a government-wide enterprise. The Minister of National Defense(MND) have developed the MND-AF as a standard methodology for EA and the ADDMe as a standard methodology for CBD. But it is possible to develop products of WD-AF and ADDMe redundantly because the process of MND-AF and ADDMe is not quitely aligned. The purpose of this paper is to present a scheme that ADDMe can reuse the artifacts of MND-AF by analyzing the relationships between two processes. In order to identify the relationships between two processes, we first identify the relation of a 'definition' part of two processes and then identify the relation of an 'attribute' part based on the relation of a 'detailed definition' part. As a result we found that 113 attributes of MND-AF are related to 49 attributes of ADDMe. Therefore the proposed study will decrease the development cost and time and will be a good example for aligning the process of EA and CBD methodology.

As the concurrent engineering concept has emerged along with the support of optimization techniques, lots of endeavors have been made to apply optimization techniques to actual design problems for a holistic decision. Even if the range of design problems which the optimization is applicable to has been extended, most of ship designs still remain in an iterative approach due to the difficulties of seamless integration of all related design activities. In this approach, an entire design problem is divided into many sub-problems and carried out by many different disciplines through complicated internal interactions. This paper focuses on preliminary ship design process. This paper proposes a process centric integrated framework as the first step to establish a workflow based design process management system. The framework consists of two parts; a schedule management part to support a manager to monitor current progress status and adjust current schedule, and a process management part to assist a design to effectively perform a series of design activities by following a predefined procedure. Overall system are decomposed into modules according to the target to be managed in each module. Appropriate interactions between the decomposed modules are designed to achieve a consistency of the entire system. Design process model is also designed on a thorough analysis of actual ship design practice. The proposed framework will be embodied using a commercial workflow package.

본 논문에서는 안테나 설계에 있어서 자동화 설계 프로세스를 제안하고자 한다. 안테나 설계는 최적화를 위한 반복적인 시뮬레이션 과정을 거쳐야 하며, 설계된 안테나의 실제 적용 시 튜닝 과정을 통한 시간이 많이 소요되는 경우가 있다. 본 논문에서는 유전자 알고리즘을 이용 하여 초기 안테나 모델 설계 시 안테나 설계자에게 사용 가능한 다양한 모델을 제시하며, 안테나 설계 시 중요 인자를 제시함으로써 초기 설계 및 방향설정의 시간을 줄이고자 한다. 사용된 최적화 알고리즘은 Non-dominated Sorting 유전자 알고리즘이며, 이 알고리즘은 multi-objective를 가지는 문제 해결에 적합한 알고리즘이다. 안테나 설계를 위한 EM computational tool로는 ESP V.5가 사용되었다. 시뮬레이션 결과를 통해 사용 가능한 적합한 안테나 모델을 제시하였다.

대학의 게임개발 프로젝트에서 게임QA를 수행할 때 일정한 가이드라인이 없이 진행되는 경우가 많다. 게임QA 중 소프트웨어 테스팅 부분은 최근 확정된 ISO/IEC/IEEE 29119 표준을 기준으로 할 수 있을 것이다. 다만 29119 표준의 내용이 매우 구체적이므로 이를 대학의 학기라는 제약에 맞춰서 진행하기 위해서는 표준이 제시하는 프로세스에 대한 최적화 과정이 필요하다. 본 논문에서는 ISO/IEC/IEEE 29119 표준을 간략하게 살펴보고 이중 테스트 계획 수립 프로세스를 어떻게 최적화할 수 있는지 방안을 제시하였다.

국내 B2C 서비스 산업의 경쟁력을 높이기 위해서는 고객 중심의 피드백 분석 및 프로세스 개선이 필요하다. 그러나 현재 우리나라는 B2C서비스와 관련하여 고객의견 수집 및 분석기술이 미흡하다. 본 연구에서는 다양한 방법으로 고객 피드백 정보를 수집 및 분석하고, 이를 기반으로 서비스를 재구성할 수 있는 프로세스 추론 방법을 제안한다. 이것을 위해 고객 피드백 정보와 프로세스 분석 정보를 바탕으로 서비스 온톨로지 모델링을 한다. 향후, 그것을 기반으로 한 추론을 통해 서비스 추천, 서비스 재구성, 프로세스 최적화를 위한 정보를 제공할 수 있다.
