A Rough Programming Model Based on the Greatest Compatible Classes and Synthesis Effect

Abstract

The globalization connects different parts of the world tightly, one region can be closely interacted by another region. The globalized environment can become dynamic and turbulent, thus brings uncertainties into decision making. A critical challenge in system science is to deal with the uncertainties such as fuzziness, randomness and roughness of information. In this paper, a programming model in rough sets is presented. First, the characteristics and limitations of the existing rough programming methods are analysed systematically. Second, the necessity and feasibility of developing a new rough programming model is discussed, and the model is developed on the basis of the greatest compatible classes and synthesis effect. Finally, the effectiveness and characteristics of the newly developed model are validated through a case study. The result illustrates that the new programming model is of significance in practical applications, and it makes it possible to take decision preferences into account of the decision-making processes effectively.

An Empirical Study on the Dynamic Relationship between Higher Educational Investment and Economic Growth using VAR Model

“…The complexity of a system is determined by the number of system components, interactions and their dependences on the time domain (Chaudhry et al, 2000;Tang et al, 2000;Xu, 2000;Xu et al, 2000;Li et al, 2013;Wan and Jones, 2013;Zhao et al, 2014). The dynamic relationship between higher educational investment and economic growth is one of the interesting topics in interdisciplinary systems research (Xing et al, 2013;Xu, 2013).…”

The Application of Cognitive IoT for Smart Manufacturing

“…Many existing technologies, methods and techniques are available for customer usage, however are not appropriate for cognitive manufacturing applications that have severe safety and security requirements. International cooperation efforts and a system-level perspective are required for empowering the capabilities to tackle the IoT, object detection and face detection related challenges [32]- [41].…”

Introduction: Systems Science in Industrial Sectors

“…To deal with the uncertainties, rough set theory, fuzzy set theory, stochastic probability theory and grey systems theory have been developed. In the paper entitled ‘A rough programming model based on the greatest compatible classes and synthesis effect’, the authors propose a programming model in rough sets, with real‐world applications in industrial development (Li et al ., ).…”
