In the current Web, e-document has been the most common vehicle for delivering and exchanging information. As the amount of e-documents has grown enormously, effective classification facilities are urgently needed to classify and query e-documents users want. In this paper, we propose a method to classify e-documents into a set of predefined categories based on Fuzzy Cognitive Map (FCM). The e-...

This study investigates the problem of design adequate models for non-linear large and complex plants with high uncertainties. A new hierarchical structure is considered that utilize soft computing methodologies to model the supervisor. The proposed approach is based on the combination of different modelling techniques within a hierarchical supervised structure that has the ability to model sys...

Nowadays, higher education institutions (HEIs) are facing the need of constant monitoring of users’ interaction with Learning Management Systems (LMSs), in order to identify key areas for potential improvement. In fact, LMSs under blended (b-) learning mode can efficiently support online learning environments (OLEs) at HEIs. An important challenge would be to provide flexible solutions, where i...

s: Decision making problems always puzzled managers and decision makers in enterprises or organizations. There are many useful soft operation research methods could solve the complicated problem. The paper raises two classic approaches ANP (Analytical network process) and FCM (Fuzzy cognitive map). Those two methods have some similarities and differences. In thus, according to different decisio...

One of the essential factors project success is selecting proper delivery method. This study aimed to provide a new hybrid decision-making framework assist stakeholders in evaluating and most appropriate Project Delivery System (PDS) documenting decision process. For this purpose, selection PDSs were obtained from literature review, critical screened based on fuzzy Delphi method, whereby expert...

Suicide has become a significantly prominent issue because high frequencies of occurrences make it one of the top three causes of death for young people in the United States. To prevent suicide attempts, it is important to identify suicidal tendencies in the behavior, speech, or writing of an individual as early as possible. This paper demonstrates one technique of analyzing written material to...

Collaborative planning, forecasting and replenishment (CPFR) coordinates the various supply chain management activities including production and purchase planning, demand forecasting and inventory replenishment between supply chain trading partners. This study proposes a systematic way of analyzing CPFR supporting factors using fuzzy cognitive map (FCM) approach. FCMs have proven particularly u...

This work describes a knowledge-guided clustering approach for mineral potential mapping (MPM), by which the optimum number of clusters is derived form a knowledge-driven methodology through a concentration-area (C-A) multifractal analysis. To implement the proposed approach, a case study at the North Narbaghi region in the Saveh, Markazi province of Iran, was investigated to discover porphyry ...

Industry 4.0, or the fourth industrial revolution, is a new paradigm in manufacturing digitalization, which provides various opportunities for enterprises. 4.0 readiness models are worthy methods to aid organizations tracking development of their businesses and operations. Nevertheless, there different models; no work has yet analyzed degree causal effects relationships using fuzzy cognitive ma...

This study is concerned with a fundamental issue of time series representation for modeling and prediction with Fuzzy Cognitive Maps. We introduce two distinct time series representation schemes for Fuzzy Cognitive Map design. The first method is based on the temporal relationships, namely time series amplitude, amplitude change, and change of amplitude change (dynamics perspective). The second...
