Scale Consistency Quantification for Subjective Evaluation of Vehicle Dynamics
The subjective evaluation of vehicle dynamics performance is widely applied in different stages of vehicle development. However, the rating result has frequently been challenged because it is easily affected by various subjective and objective factors. Currently, there is no suitable index for determining evaluator’s consistency when performing a subjective evaluation of vehicle dynamics. This evaluation is quite unique, with limited samples, multiple indices, and poor repeatability, in addition to being stratified and two dimensional. The cross-grouped factor analysis (CFA) method is proposed to identify the scale for a subjective evaluation and to quantify its consistency. An application case study revealed that the proposed method is effective.
The concept of quality is revisited to evidence its applicability beyond the product and economic transaction level, to cover every kind of human and social relation. A very important extension indedd in this globalization era, where an increasingly interconnected world badly needs rules and means to improve quality, both at economic and political level. To that iam, some commonplaces about quality need to be exposed to criticism and the close connection between “value” and “quality” concepts must be highlighted. Generalization of the quality related concepts could appear to be just a theoretical issue were it not for the fact taht it opens the door to the extension of “quality management” concepts to every kind of organization: from the company to the state to the planet. “Managing for quality” appears to be a fundamental issue for all human‐made systems.
