In a product development process, it is crucial to understand and evaluate multiple and synergic aspects of systems such as performance, cost, reliability and safety. These aspects are mainly considered during later stages of the design process. However, in order to improve the foundations for decision-making, this paper presents methods that are intended to increase the engineering knowledge i...

Software Conceptual Integrity has been considered a cardinal concern for design and development of software systems. But, except for verbal descriptions of desiderata, there were no formal tools to guarantee that conceptual integrity is attained. This paper proposes an axiomatic algebraic approach, based upon the assumption that the software system in each level of the system hierarchy is repre...

This paper explores the impact creative engineering design methodologies will have on the development of conceptual system designs for technically complex systems. To meet the requirements of the many innovations of products and their technology, these technically complex systems must be innovative to make effective use of them. This report generates a value-chain that shows the link between cr...

Despite a large body of research on creativity in architecture, the concept of creativity as a multi-faceted phenomenon in design studios is still challenging. The present study aims to analyze the related literature and systematically categorize them to provide a conceptual framework to enhance creativity in design studios. By using a qualitative researcher method along with Sandelowski and Ba...

Within a conventional aircraft design process, the horizontal tail and vertical are generally sized via volume coefficient methods. In this manuscript, an improved method for conceptual based on multidisciplinary optimization (MDO) approach with stability control constraints has been developed. To develop method, first, requirements have derived from regulations fundamental functionalities of p...

Altimetry has become the focus of global climate studies because it is the only tool available able to provide both mesoscale (100-500 kIn) and basin-scale (10,000 kIn) circulation information on a global, synoptic basis. . The Atlas-launched Navy Geosat mission proved the capability of the radar altimeter to measure the mesoscale ocean features. A lightsat compatible Geosat Follow-On Technolog...

In the architectural design, designers are focused on the early stages of the design process or conceptual design. The ultimate goal of this stage is to find a solution for an existing problem, investigate design space, or explore an idea. This stage conventionally begins with sketches and diagrams to explore ideas and solutions; the ambiguity and vagueness of conventional freehand sketching ca...

Ka band multimedia satellite networks have the potential to bring two-way broadband services directly to the end-user while providing ubiquitous global connectivity with Quality-of-Service (QoS) guarantees. TRW’s satellite network architecture design process involves Demand, Design and Financial modeling. The main Design challenge is to balance the delivery of network services and QoS demanded ...
