Abstract Ayyildiz et al. (Environmental Science and Pollution Research (2021), 1-13) pointed out that it is important to identify and minimize the critical risks in the transportation of hazardous material. For the same, Ayyildiz et al. proposed an effective integrated decision-making methodology by combining the Modified Delphi Method (MDM) and Pythagorean fuzzy analytic hierarchy process (PF-AHP). In this integrated methodology, PF-AHP method is utilized to obtain weights of main and sub-risk factors in order to rank these factors. In Step 5 of PF-AHP method an interval valued Pythagorean fuzzy pairwise comparison matrix is transformed into a crisp matrix and then crisp AHP is applied to obtain the normalized weights from the transformed crisp matrix. It is quite evident that the crisp AHP is used only for crisp pairwise comparison matrix. However, after a deep study, it is observed that the transformed crisp matrix, obtained on applying the steps of Ayyildiz et al. methodology, violates the reciprocal propriety of pairwise comparison matrix. Therefore, to apply crisp AHP on the transformed crisp matrix is mathematically incorrect and will lead to problematic decision-making approach. Hence, may result in a heavy loss in any value-added model such as hazardous material transportation problems. Therefore, the Ayyildiz et al. methodology is not valid in its present form and cannot be used to find the solution of such type of real-life problem. Keeping the same in mind, the focus of this discussion is to make the researchers aware about these mathematical incorrect assumptions and the necessary modification is suggested.

Service Coverage

One way to increase service coverage of telecom operators such as PT. Smartfren is by adding or building new Base Transceiver Stations (BTS). To determine where to place the new BTS, there are several criteria and sub criteria that must be considered. Incorrect choice of criteria and sub criteria or lack of data can cause the new BTS to be built in a less precise location thus the service coverage will not be optimal. Based on that consideration, a decision-making system application to determine BTS location is created using Fuzzy AHP method with VB and MySQL applications. The outcome of this application is a list of area, in several regencies, from the highest to the lowest score of BTS location based on the selected criteria and sub-criteria. It helps the user in knowing the most appropriate location for the placement of PT. Smartfren’s new BTS. [TURNITIN 19%, 22022017]

Opening Up

The opening-up of an opencast system is fundamental in the structure of the mining and technical system (MTS) and the efficiency of the functioning and development of the MTS as a whole depends on the quality of the assessment of its functioning. The decision-making on the reconstruction of the mining and technical system and its subsystems in modern conditions cannot be based only on the basis of a comparison of the technical and economic indicators of the options. Decisions on the development of MTS should be made on the basis of measuring and evaluating the parameters and indicators of the elements of the opening-up of an opencast system and taking into account the requirements of the sustainable development concept, i.e. taking into account the technical, economic, environmental and social aspects of the consequences of decisions taken. However, most of the existing approaches do not allow a comprehensive assessment of all elements of the opening-up of an opencast system, which able to take into account the interrelation between the indicators of the MTS elements in terms of the sustainable development concept. In this paper, we analyzed the factors of the sustainable functioning and development of the MTS and the opening-up of an opencast system, the parameters and indicators for their assessment, as well as the decision-making methods used in the practice of operating the MTS subsystems. The system of parameters and indicators for evaluating the opening-up of an opencast system has been substantiated, taking into account five groups of factors for the functioning of MTS: technical, technological, economic, social and environmental. The use of the fuzzy AHP method for ranking the parameters and indicators of the opening-up of an opencast system is proposed. The methodology and calculation example of assessment of the sustainable development of the opening-up of an opencast system using the fuzzy AHP method are presented. The results of the ranking of the parameters and indicators of the openingup of an opencast system showed that the most significant parameters are economic efficiency, the productivity of the transport complex, social efficiency and environmental efficiency, and the indicators are total income, emissions of pollutants and working conditions of personnel. Using the approach proposed in the work to assess the opening-up of an opencast system will improve: the quality of the assessment of the elements of the opening-up of an opencast system for compliance with the requirements of the sustainable development concept; the effectiveness of decision-making on the design, operational and strategic planning of the MTS development,taking into account the coordination of economic goals with goals in the field of ecology and social development.

Purpose – The changes that occurred in the market, resulting from technological advancement, made companies pay attention to innovation in their processes, products or services, as a way to stand out. To enhance innovation in companies, focusing on leadership is an effective way. In this sense, the present study aimed to develop a model in order to list the priorities related to leadership and its interface with innovation, under the top management perspective of a telecommunications company.Design/methodology/approach – For the development of the model, the Fuzzy Analytic Hierarchy Process (Fuzzy-AHP) method was used to identify such factors and the best alternatives so that the investigated company can make consistent decisions. Thus, the criteria chosen by the Manager and Director were discovered, as well as the alternatives that they cherish, contributing to the development of innovation within the company.Findings – The results showed that the perception of the two interviewees was similar, however, it is emphasized that they should better choose how to apply innovation within the company.Originality/value – This study opens the way to highlight the importance of the theme of leadership and its interface with innovation for professionals in the management area, favoring decision making, in addition to contributing to the literature, deepening the debate on the theme of leadership and innovation, which is still incipient and needs development.

Energy consumption constantly increases day-by-day, which enforces suppliers and consumers in to plan the needs for the short and long terms. This obliges studying to device useful and accurate ways to predict the need for use in corresponding periods of the time. One of these fields of study is the efficient and uninterrupted energy supply over distribution infrastructures. It is obvious that the efficiency and performance of energy supply companies plays an important role in energy supply itself and has a critical value in determining and finetuning the future roadmap of the sector. In this study, the performance and efficiency of energy supply companies with respect to productivity is investigated over a case study of an electricity distribution company in Turkey. The factors affecting the company’s performance and their corresponding weights have been determined and elicited using analytical hierarchy process (AHP) and the Fuzzy AHP methods, as two well-known multi-criteria decision-making methods. The AHP method differs from other methods in that it can evaluate qualitative and quantitative expressions together, calculate the consistency rate, and show the hierarchical structure between sub-criteria and alternatives depending on the criteria. In addition, it is a decision-making method that is widely used in the literature. The Fuzzy AHP method, on the other hand, reflects the evaluations of people better than the classical AHP method and provides convenience during the evaluation. The results help demonstrate that the criteria elicited to evaluate the company’s energy supply performance plan a crucial role in developing strategies, policies and action plans to achieve continuous improvement and consistent development.
