One of the most critical activities that the PhD. Student maybe faced is selecting supervisor for her dissertation. Most often these decisions are in the form of a selection problem from a finite number of choices. The selection is based on a set of criteria, such as professors' reputation, knowledge, and matching of interests among others. However, the application of these criteria in selecting a supervisor is often done in an unplanned manner, which can become one of the reasons for regret, lack of motivation, and poor quality of research output.The need for having a supervisor who fits well with the students' preferences can hardly be overemphasized. The basic assumptions in this study, is that the criterions have relationships with each others. So the AHP method could not be a good way for evaluating the problem.The paper aims to demonstrate the use of analytical network process (ANP) in the selection of a thesis supervisor. A survey of doctoral students is conducted to obtain a list of criteria that are significant for selection of a research guide and then modeled as an ANP problem. A survey of junior and senior doctoral students in Tehran University is also conducted to ascertain the relative weights of the criteria elements to demonstrate the application of the proposed method.
Purpose The purpose of this study is to formulate exploratory scenarios of Operations Research through the critical uncertainty approach and Soft Systems Methodology. Design/methodology/approach In this study, to formulate plausible scenarios, the discipline of operation research internal and external experts’ opinions of this field have been gathered through Delphi approach and uncertainty questionnaires. After use of the most important uncertainties, plausible scenarios of operations research have been mapped with the help of experts through co-thinking workshops. Findings Four scenarios are presented in this study. These scenarios include Solar System, Esfandiar's Eye, Rival’s Setraps and Legendary Simurgh. Naturally, the imagination of such a unitary future for all academic communities is an expectation far from reality, and given the conditions of each of these futures or any integration of them is imaginable. Originality/value Operations Research models have been faced with variously multiple changes since its emergence until now. Investigation into the future of operations research on the necessity for his planning has not received a reasonable notice in the literature. Sporadic activities that have been carried out are also lacking in the necessary methodology. Also, there has been no research about future study using the soft Operation Research tools (Soft Systems Methodology).
Paradigms are some principles and assumptions, which define frameworks and research priorities in each discipline. Many believe that operational research (OR) is not a science and like many other sciences does not have any paradigm. However, since OR is committed to scientific methods, therefore it contains a methodological paradigm. The purpose of this paper is to consider theoretical methodologies in the field of OR. This paper performs a review on the existing literature based on interpretive hermeneutic approach. Based on literature review, the study determines four principles and assumptions for each OR paradigms and a classification of the methods are presented. The results show that OR has four main paradigms and there are many methods in OR fields to tackle a particular problem where each problem belongs to a particular paradigm. In addition, instead of using a particular method in problem situations, we can implement a combination of methodologies
Purpose By replacing traditional fossil fuels, renewable energy (RE) has the potential to become an outstanding sustainable energy supply. However, owing to technological, economic, social and legal constraints, RE is still in its early stages of development. Hence, this paper aims to analyze the sustainable development hindrances in the RE supply chain (RESC). Design/methodology/approach Twenty-three hindrances to the sustainable development of the RE industry were investigated in this research, which included a review of the expert opinion and literature. Then, a mutual relationship between the hindrances by integrating interpretive structural modeling and decision-making trial and evaluation laboratory in fuzzy environment was established. Furthermore, using the cross-impact matrix multiplication applied to a classification analysis, these hindrances were grouped. Findings The findings show that the important hindrances are “lack of standards for the RESC (H19), lack of entrepreneurship support (H21), lack of incentives/subsidies to encourage RE producers to compete (H30) and lack of governmental support for sustainable supply chain solutions (H31). Originality/value This research provides unique insights into the area of sustainability in RESC. To the best of the authors’ knowledge, this is the first paper to analyze the sustainability hindrances in the RESC.
This article examines the impacts of Infrastructural integration of Regional transport (IIRT) on tourism and the idea of using IIRT to promote tourism. The process of striving for IIRT requires a number of factors to be operationalized, among which the most common are: multimodal terminals (MMT), shared stops (SST), highway construction and improvement (HCI), and railway construction and improvement (RCI). The aim of this article is to evaluate the impacts of IIRT factors on the factors which lead towards the promotion of tourism. The results showed that Guilan province, despite of profiting with all four major transportation modes, has a lack of infrastructural integration among all transportation modes. Furthermore, it was concluded that IIRT can have a significant effect on the promotion of tourism and it can be used as an approach to promote the tourism industry of Guilan province with using several strategies in this regard.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
