In the customer-centered world, which is used internet and social network services actively, it is important that their needs should be embraced into systems. Our study proposes a technique to normalize and select 1,800 customer's needs at C company. In order to normalize the requirements, we have specified requirements by considering a standard for requirements specification, have identified a set of keywords of requirements and have constructed a relation-graph of requirements. The graph presents objectives to design and build a system, and shows a degree of relative importance for each requirement. And then, we propose a techniques for requirements selection according to their contribution points, which are calculated using relative degree. We demonstrates our techniques by a case study of C company.

내장형 실시간 시스템은 점차 소형화, 다기능화 하여 그 복잡도가 증가하고 있다. 이로 인해 소프트웨어 아키텍처의 적용이 요구되고 있다. 아키텍처를 적용하기 위해서는 내장형 실시간 시스템에 적합한 아키텍처를 선정해야 하며, 선정한 아키텍처는 처리속도와 같은 비기능적 요구사항을 만족할 수 있어야 한다. 이에 본 논문에서는 내장형 실시간 시스템 개발 중 아키텍처 선정 시 처리속도에 기반하여 아키텍처를 선정할 수 있는 성능평가 절차와 고려사항을 제안한다. 이를 통해 사용자가 제시한 성능적 요구사항에 적합한 아키텍처를 선정 할 수 있다.

복잡하고 방대해진 시스템 개발에서 다양한 이해 관계자들의 요구사항을 시스템에 정확히 반영해야 하고, 이를 위해 시스템의 품질 속성과 이해관계자들의 이해관계를 반영한 소프트웨어 아키텍처의 설계가 성공적인 프로젝트를 위한 중요한 이슈가 되었다. 본 연구에서는 아키텍처 설계 과정에서 식별된 아키텍처 접근법 대안들에 대해 시스템의 요구사항에 대한 만족도를 평가하여 설계단계에서 설계자들이 가장 적합한 아키텍처 접근법을 선정 하도록 하고 있다. 즉 평가를 통해 선정된 아키텍처 접근법을 기반으로 아키텍처 설계를 확장해 나감으로써 설계 산출물의 신뢰성과 완성도를 높이는 효과를 기대 할 수 있다.

To design a software system many architecture styles have to be combined to construct the overall architecture of the system What to choose among various architecture styles or architectural approaches depends on the fact of what kind of functional or non-functional quality requirements the system should satisfy In this study, we define the method to choose suitable architectural approaches by the satisfaction level of system requirements that is evaluated through estimation about technical parts of architectural approaches, and verify the evaluation method by the case study that apply the evaluation method to choose architectural approaches for message system.

동일하거나 유사한 기능을 수행하는 소프트웨어 제품들 중에서 사용자 요구사항에 가장 적합한 제품을 결정하기 위하여 측정과 평가 및 선정을 실시하는 것을 매우 중요한 일이다. 이러한 소프트웨어 제품의 평가와 선정은 대량 구매시 객관성 확보를 위해 특히 중요하다. 소프트웨어 제품의 평가를 위한 절차는 평가 대상 제품의 속성 결정과 측정, 속성의 중요도에 따른 가중치 부여, 그리고 평가와 선정 모형을 통한 최적제품의 선정이나 우선순위의 결정이다. 본 연구에서는 이러한 절차에 따른 가중치 부여 방법으로는 계층적 분석과정을 이용하고, 제품의 평가와 선정 방법으로는 4개 보상모형과 7개 비보상모형, 그리고 4개의 DEA(Data Evelopment Analysis)모형을 종합적으로 설명한다. 또한 본 연구에서는 위의 15개 평가와 선정모형을 사용하여 Infoworld(Jan.1997)에서 발표한 '문서 작업흐름 관리' 소프트웨어 제품의 속성에 대한 측정결과를 가지고 모형별 적용 결과를 분석한다.

In National Defense field, the importance of M&S and T&E has been increased due to complexity of modern Weapon System. And research reducing time and cost is being conducted continually on using limited resources efficiently. In the existing research, Weapon System's Performance Evaluation System using the Process-based method has been in progress. But, Objective basis or scientific method is insufficient in selecting appropriate function of a target to performance evaluation. Due to this, it's difficult to select functions suitable to the situation in same type. Also, Requirements of user and interrelation of evaluation factors can't be reflected systematically. In this research, it proposes the method to reflecting requirements of user, interrelation of elements in realistic situation for selecting evaluation object in Performance Evaluation Simulation. First, Evaluation Objects is selected using ANP which is multi-criterion decision making method. Second, decision support system is constructed using Programming Language(C#) based on the research result.

It is very important the government project should be supported by enough budget for proceeding. The insufficient budget by poor budget estimating uesd to bring about discontinuing for the project. This is originally caused by inaccuracy for cost estimating about system and evaluating for system requirements on the projet initial phase. The system requirements is technical requirements that converted the user needs and is needs for communicating between stakeholder and developer and manufacturer. Also the system requirements is the primary factor to make the project cost. The cost estimating is not easy due to complication of cost factors and an aberration between cost estimating and actual cost. Specially, on the project initial phase, shortage of detail information for project make more difficult to do cost estimating. This study proposes the architecture for validating proper system requirements by using cost estimations methodology on the project initial phase and shows the computer tool for simulating the proposed architecture.

The rapid increase in the use of many commercial software products has necessitated a systematic and objective method of their evaluation and selection. Our study focuses on the assignment of weights and choice of proper models. First, the weights of attributes are assigned consistently by using the analytic hierarchy process. Second, many models, which can be suitable for the structure of evaluation and selection for software product, are collected, categorized into two types of model, and compared in terms of their strength and weakness. The models involved are four compensatory models and seven noncompensatory models. Finally, they are analyzed through the application of specific software products(database data modelers) in terms of their attributes. Our study enhances the applicability of models to a variety of user requirement utilizing the evaluating procedure and applications.

VE is one of the most effective and systematic tool available to achieve the required function at minimum cost and manage in many industrial fields. The purpose of the preparation phase VE job plan is to establish a cooperation system referring to groups for the successful implementation of VE, and to achieve a common objective to collect sufficient materials required in the analysis phase. The Quality Model is used to measure the requirement of shareholders(users and owners)in the project. It also offers a guideline on decision making when executing the function definition, function arrangement, function evaluation, and the idea evaluation of VE. However, the current the preparation phase business confirms that the required items of owners and users has not suggested definite goals and directions. This study analyzes the problems of current work in the preparation phase from case study, survey and interviews of experts. It then proposes a new process after understanding the required items of owners, users and experts.
