Huamin Li, Tian Hao Tang · IEEE Systems Journal · 2023
The development of intelligent vehicles (IV) promotes smart transportation, and cyber physical systems (CPS) offers the possibility to address the increasingly prominent intelligent transportation management needs and data problems. The IVCPS is a technological integration of IV, CPS, traffic science, and transportation engineering, representing an emerging interdisciplinary complex system. In order to accurately and comprehensively assess the intrinsic functional elements of IVCPS, this article constructs the framework of IVCPS evaluation, and proposes a comprehensive evaluation method of functional elements of IVCPS based on the cloud model that can perform synergistic analysis of quantitative and qualitative indicators. The index weights are determined by a combination of assignment methods to construct the IVCPS functional element evaluation system. The primary indicators and the secondary indicators are selected and evaluated. The cloud numerical characteristics of the evaluation indexes under the secondary evaluation indexes of IVCPS are calculated by using cloud model algorithm, and the cloud numerical characteristics of the evaluation of the whole system can be obtained. The IVCPS comprehensive evaluation cloud model can refine the key features of the system, and then some targeted suggestions are proposed.
