In designing and evaluating a new product, the company needs to give thought to the entire spectrum of produceability, usability, and ultimate reliability, as well as safety of users. For each design review(DR) stage, a formal, systematic, documented review and evaluation of a product design is conducted to assure that the product is safe and reliable, that costs and materials have been optimized, and that the design complies with its specifications and requirements. This paper presents how to improve development process for product's safety and reliability. The process requires gathering the appropriate information, determining the limits of the product, estimating risk associated with the task-hazard combinations, and reducing risk according to a prioritized procedure.

While systems engineering has been widely applied to complex system development, some evidences are reported about major budget and schedule overruns in systems engineering applied. On the other hand, many organizations have been deploying Design for Six Sigma (DFSS) to build Six Sigma momentums in the area of design and development for their products and processes. To explore the possibility of having a DFSS complement systems engineering process, this process reviews the systems engineering with their categories of effort and DFSS with its methodologies. A comparison of the systems engineering process and DFSS indicates that DFSS can be a complement to systems engineering for delivering higher quality products to customers faster at a lower cost. We suggest a simplified framework of systems engineering process, that is, PADOV which was derived from the generic systems engineering process which has been applied to the development of T-50 advanced supersonic trainer aircraft by Korea Aerospace Industries (KAI) with technical assistance of Lockheed Martin. We demonstrated that each phase of PADOV framework is comprehensively matched to the pertinent categories of systems engineering effort from various standards.

The Development of Cost Management is embossed efficiently to use the budget for the construction industry. The government is exploring every efforts and polices to control increasing the budget for the construction industry. However, despite of the government's efforts, researches are insufficient for a cost management of development. Also, the changed cost of construction by frequent plan change is caused of decline in quality etc during an accomplishing project. Therefore, in this study, analyzed about principal official phase of design phase to solve the problem. In order to define clearly the target cost concepts in the planning phase apply to the DTC(Design To Cost) concept and technique at the development of cost management process which will be able to manage the enterprise expense. It's process is expected with the fact that will be the possibility efficiently of fixing target cost in the planning phase by the construction client and designer.

This paper will describe design process and its results that are minimized unaddressed feature of product development processes. This process provides integrated system design process by context analysis of EIA 632 standard process, interface definition from activity decomposition, integration of related activities, and definition of concurrency & sequential activities flow. This process and method application will contribute to minimize time loss that is emerged from activities iteration by not definitely definition of activities interface.

디자인 패턴은 소프트웨어 생산성 향상을 위해 사용되는 효율적인 기술로써 인식되고 있다. 이러한 디자인 패턴은 소프트웨어 설계시 자주 발생되는 특정 상황에 대한 문제를 효과적으로 해결할 수 있는 방법을 제공한다. 현재까지 다양한 분야에 필요한 디자인 패턴들이 발견되고 이들의 활용성을 증명하는 연구가 진행되고 있다. 그러나 소프트웨어 개발에 이들 디자인 패턴을 효과적으로 적용시키기 위한 체계적인 접근방법에 대한 연구가 부족하다. 본 논문에서는 점진적 디자인 패턴 통합을 통한 패턴지향 소프트웨어 개발 방법을 제시한다. 이를 위해 먼저 디자인 패턴을 활용하는 개발 프로세스를 정의하고 이 프로세스에서 요구되는 점진적 디자인 패턴 통합기법 및 디자인 패턴 기반의 소프트웨어 설계관점을 보인다. 또한 소프트웨어 시스템에 존재하는 디자인 패턴의 효율적인 추적 및 관리방법을 제시한다. 이러한 과정은 피드백 프레임워크 시스템 설계를 통해 구체화된다. 소프트웨어 개발시 디자인 패턴을 이용한 체계적인 접근과 활용은 초기 개발 단계부터 디자인 경험과 기법들을 효과적으로 활용할 수 있게 함으로써 시스템 개발에 효율성을 증대시킨다. 그 결과보다 안정되고 재사용 가능한 시스템을 이끌어내고 개발 시간과 비용을 단축하는 효과를 제공할 것이다.

This paper introduces two platforms created by the development team at CORE studio, Thornton Tomasetti's global innovation studio. Collaborative platforms change the way that parties communicate and develop projects. Wikipedia is one of many great examples for a platform that supports collaborative development of a product - the world's largest encyclopedia. In the AEC industry, no such platform exists that can be used for collaborative development of a building project, and hence, information exchange between the parties involved, and modeling programs used in a project is slow and opaque. The platforms introduced in this paper allow for much greater transparency at all stages of the building design process, and hence improve the flow of information between parties involved in the process, both firm-internal and external. While traditionally, the use of a large number of different modeling and analysis platforms is hard to manage by a project team; this paper introduces methods that strengthen the design process by using a multitude of programs needed in the different building design phases.

Generally cam-follower systems consist of two elements: Cam is for rotating motion and follower for reciprocating motion. Depending on the shape of cam and type of follower, the motion of cam-follower system is determined. Thus design process and analysis process must be well defined. The design process means to find the coordinates of cam shape which can be defined the given motion of follower and the analysis process means to determine the motion curve of follower corresponding to the given cam based on the dimensions of a cam-follower system. This paper consists of two parts : One is for development of a numerical method for design and analysis of cam-follower systems, the other is for development of a CAD program and its application. As the second part of the paper, the structure of a CAD program is introduced. Four data files are used in the program where the design process and the analysis process are carried out interactively to en hence its availability to the industrial applications. The first part of the paper 'presents the iterative contact method which can determine the contact points and their angles between cam and roller.

Every car manufacturer desires to reduce the new car development time spent in improving the safety, NVH, lightweight, reliability and environment friendly features of the car. Other considerations such as planning, exterior and interior styling, packaging, color, and material selection increase the complexity of the car design process. This paper proposes a personal DDP (Digital Design Process) to utilize the engineering analysis and design/styling software for car design. DDP can be efficiently used by a team of car research center or a studio with small number of engineers, helping ordinary engineers becoming ambidextrous in design as well as engineering applications. The concept model starts from idea sketch, rendering, and 3D surface model with CAS (Computer Aided Styling) to the final safety estimation by using proposed DDP based on engineering technology (CAD, CAE). The concept model proposed a hydrogen fuel cell sports coupe which could be available within next 10 years. The proposed DDP can not only reduce the new car development time but also be adapted into designing of varied products such as aircraft, yacht, electrical equipment and sports gear.
