The research and development stage can improve the goal level of the project through systematic operation and management of systems engineering. The test evaluation tasks in the R&D process have a lot of connections with the system engineering in terms of requirement management, and the methodology for deriving the requirements when establishing the test evaluation items has been consistently required. In this paper, we propose the process of effectively establishing and using QFD (Quality Function Deployment), a tool to manage customer requirement, and drawing up HOQ (House of Quality) in the search and exploratory development stage of the self - propelled mortar project.

In AI image generation tools, most general users must use an effective prompt to craft queries or statements to elicit the desired response (image, result) from the AI model. But we are software engineers who focus on software processes. At the process's early stage, we use informal and formal requirement specifications. At this time, we adapt the natural language approach into requirement engineering and toon engineering. Most Generative AI tools do not produce the same image in the same query. The reason is that the same data asset is not used for the same query. To solve this problem, we intend to use informal requirement engineering and linguistics to create a toon. Therefore, we propose a sequence diagram and image generation mechanism by analyzing and applying key objects and attributes as an informal natural language requirement analysis. Identify morpheme and semantic roles by analyzing natural language through linguistic methods. Based on the analysis results, a sequence diagram and an image are generated through the diagram. We expect consistent image generation using the same image element asset through the proposed mechanism.

Recently, there are many corporations, schools and institutes that apply TRIZ to solve technical problems. However, in reality, only a few cases of brainstorming applications exist in utilizing forty principles of TRIZ due to the difficulty at TRIZ problem definition. In order to facilitate TRIZ applications, this study proposes the utilization of requirement definition and description tool of systems engineering in TRIZ problem definition. No requirement definition exists in general problem types that TRIZ approach is used in implementing system solution. At most of problem situations, TRIZ users reversely infer that certain problem belongs to which requirement definition it is and recommends TRIZ tools to be used for the exact problem definition. This study also proposes TRIZ problem definition method by applying the results of requirement definition process. The application of TRIZ is demonstrated to the general situation with no problem definition where the proposed method enables the proper use of TRIZ.

Value-based requirements engineering process, called The ViRE(Value-Innovative Requirement Engineering) was suggested to create an uncontested market using ERRC(Eliminate, Reduce, Raise, Create) requirements analysis. But ViRE did not provides a quantitative data analysis method for ERRC decision so as to make objective decisions for customers. In this paper, to solve this problem, we suggest a quantitative ERRC analysis method by estimating requirements cost. Our method defines user requirements and decides their weight. Then, it makes quality level table for all the identified requirements and function modules and estimate implementation cost based on their quality levels. Finally, assess each requirement's impact and then evaluate ERRC value. We could get the more objective ERRC values by evaluate the requirement weight. functional module weight, and implementation cost. And we proved the efficiency of our model by a case study, smart student ID system.

The work environment of locomotive cabs has long been an important issue in the design of railload systems since it is quite critical in terms of system's operational safety. It is getting more attention as the running speed of the trains goes up these days. To this end, this paper describes how to systematically construct a DB for the requirements set in the course of the improvement process for the aforementioned cab work environment. As a solution approach, we have adopted the requirement architecture concept to cover the whole activities required to do such as in requirements generation, DB construction, change management, and traceability management. Specifically, based on the requirement architecture framework a requirement process to collect requirements for improvement is discussed, and the guide lines are suggested for verification and validation of the developed requirements. In addition, a base schema and requirements templates are developed, which will be used in generating requirements and constructing a DB. Finally, it is demonstrated how the requirements DB for locomotive cabs can be constructed using a computer-aided tool in an integrated fashion.

국내 건설업체들은 비용절감과 성능향상을 통해 고객의 요구를 반영하고자하는 노력의 일환으로 설계단계의 가치공학(Value Engineering, 이하 VE)을 적극적으로 검토하고 있지만, 실제 VE 활동에서는 고객의 요구가 충분히 반영되지 않고 있으며, 고객의 요구를 측정하는 준비단계에서 기능분석, 아이디어 창출단계에 걸친 순차적인 진행 또한 미비한 실정이다. 본 연구에서는 고객의 요구기능이 VE 수행절차에 체계적으로 반영될 수 있도록, 공리적 설계이론(Axiomatic Design Theory)을 설계VE 프로세스에 도입하여 기존의 설계VE 프로세스를 보완하는 고객만족형 설계VE 프로세스를 제안하고자 한다. 고객만족형 설계VE 프로세스는 설계VE와 공리적 설계의 프로세스 및 특성상의 유사성을 바탕으로 두 이론의 연계방안을 정리하고, 기존의 설계VE 프로세스에 공리적 설계 프로세스를 추가.보완하는 형태로 완성한다. 이때 프로세스의 초기단계인 고객의 요구를 측정하고 정리하는 과정에서, 거주 후 평가(Post-occupancy Evaluation)를 활용하는 방안을 제시한다. 설계VE에 거주 후 평가를 활용하기 위해 평가 기준 및 방법을 설정하고, 이를 바탕으로 고객요구 측정 절차를 수립하여 그 절차에 따라 설문을 작성한다. 본 연구의 결과는 지금까지 국내 설계VE 활동에서 미진하였던 고객요구를 적극 반영하고, 기능과 아이디어의 관계에서 기능-아이디어-기능의 지그재그 창출 방법을 통해 기능-아이디어간의 연계를 명확하게 하여, 체계적이고 효율적인 VE활동을 기대할 수 있다.

소프트웨어 개발과 운영이 분산화, 대형화됨에 따라 정확하고 완전한 요구사항의 추출과 명세는 시스템의 가장 중요한 요소가 되고 있다. 또한 인터넷을 통한 공동작업 환경에서 계속적인 시스템 변경요청은 더욱 효율적인 요구사항 관리를 필요로 한다. 본 논문에서는 이러한 공동작업 환경에서 자연어 기반 요구사항 명세와 관리의 효율성을 향상시키기 위한 요구사항 명세구조와 기법 등을 정의하고, 요구공학 활동과 주기를 바탕으로 하는 요구공학 프로세서와 환경을 제안한다. 그래서 CSCW(Computer Supported Cooperative Work) 환경에서 요구사항을 정확하게 추출하고 효율적으로 관리하며 분석단계로 자연스러운 전이가 가능하도록 한다.
