Purpose This study aims to cover issues regarding traveling to a tourist destination which has seen war and terrorism. These problems can be addressed altogether, as they are interrelated. Based on tourists’ opinions, this paper aims to focus on measures or steps that can be taken to ensure changing their perceptions about a certain destination. Design/methodology/approach This study targets tourism experts for their opinions regarding the measures most necessary to change the perceptions of tourists. Their opinions were extracted through a questionnaire based on three criteria with four alternatives. Furthermore, raw data extracted are studied using the Fuzzy-VIKOR technique to rank the alternatives in order of importance. Moreover, the questionnaire also aims to know the perception of participants by asking them what would make them trust a destination with a history of terrorism. Findings The problems captivate the attention of government, guiding them to ensure that they need to focus more on physical security of tourists if they expect tourism industry to thrive. It was found that the steps needed to be taken are in the areas of international trade, cultural exchange programs and social media advertising. Originality/value Research based on improving tourist perception of Pakistan to develop Pakistan as a tourist destination is scarce. The study takes four different alternatives into account for image recovery and based on those alternatives, it provides a unique solution to the government in this regard with the necessary steps they need to take and attempts to help the government ensure tourism expansion in the country.

Energy Failure

The abundance of different energy sources such as coal, natural gas, and crude oil are in the Africa region, yet one of the lowest electric energy per capita consumption. Different factors have been attributed to this abysmal energy failure in the literature, leading to her slow economic and industrial advancement. These factors include poor maintenance of power generation infrastructure and lack of policy continuity, among others. The purpose of this article is to prioritize these power generation problems for proper budgetary allocation by managers of electric power. The fuzzy VIKOR technique is presented for the evaluation and ranking of these power generation problems. The analysis showed that poor maintenance is the most critical challenge of bedeviling power generation in Nigeria. The Fuzzy VIKOR produces the same result as the classical VIKOR used previously in resolving the problem. The proposed technique addresses the challenge of uncertainty and subjectivity by applying linguistic variables in the decision-making process, which the classical VIKOR is incapable of handling.

Sustainability evaluation of two iconic bridge corridors under construction using Fuzzy Vikor technique: A case studyABSTRACTTwo iconic bridge projects over river Yamuna in Delhi under construction have been evaluated from sustainability criteria using Fuzzy-Vikor technique. The Barapulla elevated road project was more found to be more sustainable in comparison to the Signature bridge project in terms of various indicators identified during the study. In general, the goals of providing sustainable features are finding a balance between what is important to the community, to the natural environment and is economically sound. During the study, it was verified that social, economic and environmental are the established parameters of sustainability for developed countries only whereas other issues like governance, technical parameters and inner engineering also play a key role for developing economies like India.Keywords: sustainability; Fuzzy-Vikor; governance; technical parameters; inner engineering.Evaluación de la sostenibilidad de dos corredores de puentes icónicos en construcción utilizando la técnica Fuzzy Vikor: Un estudio de casoRESUMENDos proyectos en etapa de construcción de puentes icónicos sobre el río Yamuna en Delhi han sido evaluados a partir de criterios de sostenibilidad utilizando la técnica de Fuzzy-Vikor. El proyecto de paso elevado de Barapulla resultó ser más sostenible en comparación con el proyecto del puente Signature en términos de varios indicadores identificados durante el estudio. En general, los objetivos de proporcionar características de sostenibilidad ofrecen un equilibrio entre lo que es importante para la comunidad, el medio ambiente natural y lo económicamente sólido. Durante el estudio se verificó que los parámetros sociales, económicos y ambientales son los parámetros establecidos de sostenibilidad para los países desarrollados, mientras que otros como la gobernanza, los parámetros técnicos y la ingeniería interna también desempeñan un papel clave para las economías en desarrollo como la India.Palabras clave: sostenibilidad; Fuzzy-Vikor; gobernancia; parámetros técnicos; ingeniería interna. Avaliação de sustentabilidade de Duas pontes emblemáticas e em construção numa importante via aérea usando a técnica Fuzzy Vikor: Um estudo de caso RESUMODois projetos de pontes emblemáticas sobre o rio Yamuna em Delhi, em construção, foram avaliadas a partir de critérios de sustentabilidade usando a técnica de Fuzzy-Vikor. O Projeto de Via Elevada de Barapulla foi considerado o mais sustentável em comparação com o Projeto Signature Bridge em termos de vários indicadores identificados durante o estudo. Em geral, os objetivos de fornecer recursos sustentáveis são os de encontrar um equilíbrio entre o que é importante para a comunidade, para o ambiente natural e é economicamente sólido. Durante o estudo, percebe-se que o social, o econômico e o ambiental são os parâmetros estabelecidos de sustentabilidade para os países desenvolvidos enquanto outras questões como governança, parâmetros técnicos e engenharia interna também desempenham um papel fundamental para economias em desenvolvimento como a Índia.Palavras-chave: sustentabilidade; Fuzzy-Vikor; governança; parâmetros técnicos; engenharia interna.

PurposeThe industry is relying on the preventive maintenance techniques that can minimize failures and provide industrial plants with effective equipment, but in many companies the maintenance tasks are performed very frequently and not as per plan and do not take into consideration the conditions of the plant and equipments. The failure of each and every component needs to be studied in order to choose the best maintenance strategy. This paper presents a fuzzy VIKOR (Multicriteria Optimization and Compromise Solution) technique which is used in developing a comprehensive approach for maintenance strategy selection in the Deinking plant of the paper industry to choose the appropriate maintenance strategy thereby reducing the unnecessary cost incurred on the maintenance.Design/methodology/approachIn this paper, the Fuzzy VIKOR based methodology was applied for determining the maintenance criticality index of the deinking plant of the paper industry. The effect of failure of components were evaluated by three maintenance experts on five performance criteria that is chance of failure, chance of non-detection, downtime length, severity, spare part criticality. The components were ranked according to the maintenance criticality index and thereby implementing the appropriate maintenance strategy.FindingsThe Fuzzy VIKOR technique was applied to calculate the ranking of various components of paper industry based on the views and judgment of three maintenance experts. The proposed technique suggested the appropriate maintenance strategy for various components taking into consideration the maintenance criticality index of the components.Originality/valueThe proposed technique will help the maintenance managers to solve a discrete problem with non-commensurable and conflicting criteria. The study will help the industries to reduce the unnecessary maintenance tasks and thereby reduce the maintenance cost. This will help the maintenance practitioners in choosing the best and most effective strategy for the organization with regard to the market and company situation especially in the changing business requirement of Industry 4.0.
