International Journal of Grey Systems http://publish.thescienceinsight.com/index.php/ijgs <h2>Why to publish in IJGS?</h2> <p><em>International Journal of Grey Systems</em> is the first American journal devoted to grey system theory and its application. It is published bi-annually in English in both print and online versions. IJGS publishes novel research involving Grey System Theory and related concepts. It is devoted to the international advancement of the theory and application of grey systems and uncertainty analysis. It seeks to nurture professional communication between scientists and practitioners who are interested in the theory and application of Grey System Theory. IJGS is an open access double-blind peer-reviewed journal, published by the <a href="https://thescienceinsight.com/">Science Insight</a> (USA) bi-annually. </p> en-US <p>Creative Commons Non Commercial CC BY-NC: The work is distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 License which permits non-commercial use, reproduction and distribution of the work without further permission provided the original work is properly attributed.</p> <p> </p> manager@thescienceinsight.com (Iqra Javed) 2497415255@qq.com (Nadiya Zhao) Sun, 31 Dec 2023 04:45:19 -0600 OJS 3.3.0.11 http://blogs.law.harvard.edu/tech/rss 60 Grey Assessment http://publish.thescienceinsight.com/index.php/ijgs/article/view/77 <p>The assessment of human activities is an important task, because it helps to correct mistakes and to improve the overall performance of a group. Frequently, however, the individual assessment of the members of a group is performed not with numerical scores, but with qualitative grades (linguistic expressions). This happens either because the existing data are not exact, or for reasons of elasticity (e.g. teacher for students). In such cases the mean performance of the group cannot be assessed by applying the traditional method of calculating the mean value of the individual scores of its members. In this short communication, a method developed recently by the author is presented for evaluating the mean performance of a group in such cases, using grey numbers as tools. The method is illustrated by an example concerning the assessment of the mean performance of a class of students.</p> <p> </p> Michael Gr.

The empirical outcomes reveal that foreign trade exerts a statistically significant and positive influence on the economic growth of Morocco, a relationship consistently substantiated by both the GRA and regression models. Nevertheless, it is important to emphasize that the linkage between these variables is characterized by a high degree of dynamism, influenced by a diverse array of economic determinants. Furthermore, the results point to the primary pathway through which foreign trade impacts economic growth in Morocco, highlighting its role in fostering capital accumulation and technological progress. Consequently, this study implies that strategic policies oriented toward the promotion of foreign trade and foreign investment have the potential to significantly bolster sustained economic growth within the Moroccan context.</p> <p> </p> Mohamed Ouali Copyright (c) 2023 Science Insight https://creativecommons.org/licenses/by-nc/4.0 http://publish.thescienceinsight.com/index.php/ijgs/article/view/79 Sun, 31 Dec 2023 00:00:00 -0600
