Robust parameter design (or, briefly, parameter design) has been widely used as a cost effective tool to reduce process variability by appropriate selection of control factors to make the process insensitive to noise. However, when there are strong noise factors in the process, use of parameter design alone may not be effective and an on-line control strategy can be used to compensate for the e...

Natural vibration analysis of plates represents an important issue in engineering applications. In this paper, a new and simplify method for vibration analysis of circular and rectangular plates is presented. The design of an effective robust controller, which consistently attenuates transverse vibration of the plate caused by an external disturbance force, is given. The dynamics of the plate i...

The development of complex products with high quality in dynamic markets requires appropriate robust design and tolerancing workflows supporting the entire product process. Despite large number methods tools available for designers tolerance engineers, there are hardly any consistent approaches that applicable throughout all stages. This is mainly due to break between primarily qualitative conc...

Social responsibility is a key factor that could result in success and achieving great benefits for supply chains. Responsiveness and reliability are important social responsibility measures for consumers and all stakeholders that strategists and company managers should be concerned about them in long-term planning horizon. Although, presence of uncertainties as an intrinsic part of supply chai...

Mechanical vibrations have a significant impact on ride comfort; the driver is constantly distracted as result. Volumetric engine inertial unbalances and road profile irregularities create mechanical vibrations. The purpose of this study to employ optimization algorithms identify structural elements that contribute vibration propagation provide optimal solutions for reducing induced by unbalanc...
