In this paper, we introduce an adaptive type-2 fuzzy logic controller (FLC) for flexible-joint manipulators with structured and unstructured dynamical uncertainties. Simplified interval fuzzy sets are used for real-time efficiency, and internal stability is enhanced by adopting a trade-off strategy between the manipulator’s and the actuators’ velocities. Furthermore, the control scheme is indep...

The theory of concept lattices (i.e. hierarchical structures of concepts in the sense of Port-Royal school) is approached from the point of view of fuzzy logic. The notions of partial order, lattice order, and formal concept are generalized for fuzzy setting. Presented is a theorem characterizing the hierarchical structure of formal fuzzy concepts arising in a given formal fuzzy context. Also, ...

Financial ratios provide useful quantitative financial information about company performance. Most of the economical, industrial, financial or political decision problems are multi-criteria. The application of multi criteria decision making methods significantly improves the robustness of financial analysis and business decisions in general. In this study, based on six wellknown financial perfo...

This paper has three, main objectives: (a) the establishment of competitiveness criteria for the location mode of the airport; (b) this study first divides international logistics into two stages and four modes of development categories from the viewpoint of value-added. Then, the evaluation criteria for transshipment mode and re-processing export mode are established; (c) and integrates Fuzzy ...

This study evaluates an appropriate business model for e-book firms in Taiwan. We apply expert questionnaires to calculate the weights, which contain five criteria, namely, business strategy (BS), finance characteristics (FC), market characteristics (MC), quality measurements of product and service (QS) and implementation (IM) (BCCSM) for the capability of developing the firms’ business. Then, ...

Iran is one of the flood-prone areas in world with inappropriate climatic patterns. In this study, flood risk maps three scenarios by combining Analytic Hierarchy Process (AHP), Analytical Network (ANP) and Fuzzy (FAHP) models Ordered Weighted Average (OWA), Linear Combination (WLC) models., Local (LWLC) two new models, Multi-Criteria Analysis (WMCA) Geo Technique for Order Preference Similarit...

in recent years, underactuated nonlinear dynamic systems trajectory tracking, such as space robots and manipulators with structural flexibility, has become a major field of interest due to the complexity and high computational load of these systems. hierarchical sliding mode control has been investigated recently for these systems; however, the instability phenomena will possibly occur, especia...

Military training programs have been developed to enhance soldier resilience competencies, which are necessary for soldiers perform their duties effectively under stress. The ongoing military conflict in Ukraine and the experience of previous missions abroad emphasize need effective that helps recover quickly continue missions. However, selecting most suitable program is challenging selection c...

In this paper the design and development of a hierarchical fuzzy logic Systems are investigated. A new method using genetic algorithms for design of hierarchical fuzzy logic systems are proposed. This research study is unique in the way proposed method is applied to design and development of hierarchical fuzzy logic systems. The proposed method is then applied to financial modelling and predict...

Quick population increase and the desire for urbanization are main drivers accelerating urban expansion on agricultural lands in Egypt. This issue is obvious governorates with no desert backyards. study aims to (1) explore trend of Land Use Cover Change (LULCC) through period 1991–2018; (2) upgrade reliability predicting LULCC by integrating Cellular Automata (CA)-Markov chain fuzzy analytical ...
