“…We can observe a common cause-and-effect in a group of clusters. As a rule, the criteria to be included in the group of effect cluster, in particular,: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 14; and the cause of a cluster include 15,16,17,18,19,20,21,22,23, 24 and 25. The causal relations among the criteria can be proposed as a causal diagram (Figure 1).…”

The aim of this paper is the evaluation of the success of graduating with distinction in higher education (SGDHE) using the fuzzy DEMATEL method. The observation has been done using cause and effect criteria. 11 cause and 14 effect clusters have been used in this study. The study result of this work shows that all the effects are connected to the given causes and a cause-effect graph has been generated for each connection. This proposed approach is demonstrated with the empirical case of Dire Dawa University students in Dire Dawa Ethiopia.

“…In addition to transforming cause-and-effect relationships into a structural–visual model, it is also able to identify the internal dependencies between factors and make them understandable (Feng and Ma 2020 ). Also, the method is done based on the opinion of experts to make the pairwise comparison between the factors (Hasheminezhad et al 2021 ). Obviously, estimating the opinion of experts with accurate numerical values under uncertainty is very difficult.…”

Applying the Delphi and fuzzy DEMATEL methods for identification and prioritization of the variables affecting Iranian citrus exports to Russia

Foreign trade is one of the important components in economic development and a source of foreign exchange earnings. In Iran, the government desires to develop foreign trade with a focus on non-oil exports. One of the substantial non-oil products is agricultural products. Iran is one of the top ten countries in the world in terms of producing agricultural products, especially citrus, but it does not have suitable conditions in terms of exports. Mazandaran province is a considerable source of citrus production in Iran, and the main produced citrus in the province is exported to Russia. Worth bearing in mind that although the production rate of citrus in the province is very well, the amount of export is not very appropriate. Therefore, the government struggles to adopt an appropriate approach to improve the conditions and taking the right approach is not possible without identifying the variables affecting exports. In this regard, in this study, first, the variables affecting citrus exports regarding the case are determined using literature review and the most related those to the case study are selected using the Delphi method. Then, the identified variables are ranked using the fuzzy DEMATEL method. Focusing on the results, it can be observed that “exchange rate fluctuation” and “marketing” have the most and the least impact on the development of citrus exports from the province to Russia, respectively. Moreover, to better analyze the gained results, the determined variables are divided into two main categories based on stages of trade, and each category’s variables are discussed in detail.

Copra, the dried parts Coconut flesh, the kernel of the fruit of the coconut palm (Cocos nucifera). Coconut oil extracted fro m the cauldron and its residue is coconut-oil Rated for cake, it is often used as animal feed. Copra was introduced in northern Europe in the 1860s as a source of dietary fat. milk fat. It became known in the Un ited States in the early 20th century. This includes it is an important export to Orchards now do minate. Husk is brought down by force, manually or mechanically, at a sharp point.

Further known as whole cauldron, ball or edible cau ldron, it is produced by drying the whole nut kernel intact. Exp osure of the Early for dry ing kernels to air and sunlight Method. This is still widely followed; It g ives good white color cauld ron. Very quick process, especially in places with high hu midity, Oven drying, usually in the Philippines Used. Kiln, fire pit, mainly a Covered by grid, in which the cauldron is placed, roof rain protected Made by hot air drying of a more uniform quality cauldron, First Pulling through, hot air Meets the opposite current. Nice white cauld ron is obtained which is worth more than the material dried in the sun. A well-dried pot contains 4 to 5 percent moisture and 63 to 70 percent oil.
