In this paper the application of a hierarchical fuzzy system (HFS) based on MPSS and SVC in multi-machine environment is studied. Also the effect of communication lines active power variance signal between two ∆PTie-line regions, as one of the inputs of hierarchical fuzzy multi-input PSS and SVC (HFMPSS & SVC), on the increase of low frequency oscillation damping is examined. In the MPSS, to ha...
This paper proposes the application of a hierarchical fuzzy system (HFS) based on multi-input power system stabilizer (MPSS) and also Static Var Compensator (SVC) in multi-machine environment.The number of rules grows exponentially with the number of variables in a conventional fuzzy logic system. The proposed HFS method is developed to solve this problem. To reduce the number of rules the HFS ...
The purpose of this study is to evaluate the competitive approaches of large supply chain management of the oil and gas operating company.This research is based on a multi-criteria decision-making approach using fuzzy Delphi method and network analysis process.Using literature review and a survey of a 15-member team of experts, 33 components affecting the large supply chain were extracted.It wa...
The aim of this study is codification of indicators affecting the organizational performance management in the oil industry. This research was carried out in two parts: qualitative and quantitative by fuzzy Delphi methods and exploratory factor analysis and confirmatory factor analysis. The qualitative section was conducted by semi-structured interviews with 20 oil industry experts and academic...
A method for a fuzzy hierarchical structure design is presented. The proposed method uses data to design a structure of the fuzzy subsystems. The fuzzy structure is designed level by level from data thus developing an initial fuzzy model is avoided. The methods is tested on one real-world application the daily gas consumption prediction.
