Computational system for multi disciplinary optimization at conceptual design stage

Multi-disciplinary Design Optimization Strategy in Multi-stage Launch Vehicle Conceptual Design

Multi-objective optimization approach for cost management during product design at the conceptual phase

The effective cost management during the conceptual design phase of a product is essential to develop a product with minimum cost and desired quality. The integration of the methodologies of quality function deployment (QFD), value engineering (VE) and target costing (TC) could be applied to the continuous improvement of any product during product development. To optimize customer satisfaction ...

Multi-disciplinary Conceptual Design Knowledge of Multi-stage Hybrid Rocket Using Data Mining Technique

This paper deals with the application of data mining techniques to the conceptual design knowledge for a LV (launch vehicle) with a HRE (hybrid rocket engine). This LV is a concept of the space transportation, which can deliver micro-satellite to the SSO (sun-synchronous orbit). To design the higher performance LV with HRE, the optimum size of each component, such as an oxidizer tank containing...

Integrated Decision Support System for Bridges at Conceptual Design Stage

Subjectivity is the main factor that affects the selection process of a bridge type at the conceptual design stage. Selecting the bridge type is generally influenced by many parameters. In most cases, these parameters are evaluated and assessed by engineers based on their own experience, knowledge and judgment. Therefore, in an attempt to provide some consistency and objectivity to the selectio...

Satellite Conceptual Design Multi-Objective Optimization Using Co Framework

This paper focuses upon the development of an efficient method for conceptual design optimization of a satellite. There are many option for a satellite subsystems that could be choice, as acceptable solution to implement of a space system mission. Every option should be assessment based on the different criteria such as cost, mass, reliability and technology contraint (complexity). In this rese...
