Foresight: a new approach based on the Z-number cognitive map

Abstract

Foresight has recently emerged as one of the most attractive and practical fields of study, while being used to draw up a preferable future and formulate appropriate strategies for achieving predetermined goals. The present research aimed at providing a framework for foresight with a primary focus on the role of a cognitive approach and its combination with the concept of fuzzy cognitive map in the environments of uncertainty and ambiguity. The proposed framework consisted of the 3 phases: pre-foresight, foresight, and post-foresight. The main stage (foresight) focused on the role of imagination and intuition in drawing the future in the experts’ minds and depicting their perceptions above perceptions in the form of a fuzzy cognitive map influenced by variables related to the subject under study in order to determine a preferable future. The use of a Z-number concept and integrating it with fuzzy cognitive maps in the foresight-oriented decision-making space, which was mainly saturated with uncertainty and ambiguity, was one of the main strengths of the proposed framework in the current investigation. The present paper focused primarily on the evolution of expert’s knowledge with regard to the topic of foresight. The role of Z-number in various processes, from data collection to illustration, analysis, and aggregation of cognitive maps, was considered for gaining knowledge and understanding into the nature of future. Moreover, an ultimate objective was realized through identifying, aggregating, and selecting the variables from each expert’s perspective and then the relationship between each variable was determined in the main stage of foresight. Finally, the proposed framework was presented and explicated in the form of a case study, which revealed satisfactory results.

“…Poormirzaee et al ( 2022 ) implemented 4.0 industry strategies in mining engineering based on the integration of the fuzzy Z-numbers with the VIKOR method. Izadi et al ( 2022 ) proposed a new approach based on the cognitive map of the fuzzy Z -numbers.…”

Solving Innovative Problems of Thrust Vector Control Based on Euler's Scientific Legacy

“…Euler's ideas and theory have been used before and continue to be actively applied nowadays in creating various jet devices and turbomachines. It is possible to say that Euler, in his lifetime, predicted the future for many centuries ahead and built a scientific base for this future, doing it in the spirit of holistic forecasting and "foresight" research [66]: "the best way to predict the future is to create it".…”
