<p>Requirement study and analysis forms a key component in conceptual design of new products and systems. For complex systems like defence equipment, concept design is very important and should primarily satisfy all user requirements. Brings out a new generative model for concept design of defence systems using principles of systems engineering. A structured model and methodology is presented starting from capturing the user requirements, developing multiple solutions, short listing the candidate solutions and finally selecting one or two feasible designs. The model and process is illustrated with the help of a case study on the development of a torpedo defence system for naval ships.</p><p><strong>Defence Science Journal, Vol. 66, No. 1, January 2016, pp. 81-87, DOI: http://dx.doi.org/10.14429/dsj.66.9105</strong></p>

Starting Point

The importance of the concept development phase in product development is contradictory to the level and amount of current computer-based support for it, especially with regards to mechanical design. Paper-based methods for conceptual design offer a far greater level of maturity and familiarity than current computational methods. Engineers usually work with software designed to address only a single stage of the concept design phase, such as requirements management tools. Integration with software covering other stages, e.g. functional modeling, is generally poor. Using the requirements for concept models outlined in the VDI 2221 guideline for systematic product development as a starting point, the authors propose an integrated product model constructed using the Systems Modeling Language (SysML) that moves beyond geometry to integrate all necessary aspects for conceptual design. These include requirements, functions and function structures, working principles and their structures as well as physical effects. In order to explore the applicability of SysML for mechanical design, a case study on the design of a passenger car’s luggage compartment cover is presented. The case study shows that many different SysML diagram types are suitable for formal modeling in mechanical concept design, though they were originally defined for software and control system development. It is then proposed that the creation and use of libraries defining generic as well as more complicated templates raises efficiency in modeling. The use of diagrams and their semantics for conceptual modeling make SysML a strong candidate for integrated product modeling of mechanical as well as mechatronic systems.

Design Case Study

In the field of the widespread research activity focusing on ultra light aircraft, two different needs were merged into one single design activity: the educational necessity of getting students involved into a real design effort. Our intention was to apply the conceptual design methodologies developed by our research group, which is named ASSET (Aero Space Systems Engineering Team), to a real case study. The design case study was chosen after a thorough examination of existing vehicles. Starting from a reference aircraft, the concept of the new aircraft was then conceived and is now under completely defined. The conceptual design of the new ultra light aircraft is already finished, whereas its detailed design has just begun and is proceeding through the utilization of both virtual (3D‐CAD) and physical models.

Risk Assessment Methodology

Abstract As counterfeiting techniques and processes grow in sophistication, the methods needed to detect these parts must keep pace. This has the unfortunate effect of raising the costs associated with managing this risk. In order to ensure that the resources devoted to counterfeit detection are commensurate with the potential effects and likelihood of counterfeit part usage in a particular application, a risk based methodology has been adopted for testing of electrical, electronic, and electromechanical (EEE) parts by the SAE AS6171 set of standards. This paper provides an overview of the risk assessment methodology employed within AS6171 to determine the testing that should be utilized to manage the risk associated with the use of a part. A scenario is constructed as a case study to illustrate how multiple solutions exist to address the risk for a particular situation, and the choice of any specific test plan can be made on the basis of practical considerations, such as cost, time, or the availability of particular test equipment.
