Meanwhile, the boundary behaviors of...

precise identification of the risks of power plants as a part of a comprehensive safety analysis is recommended by monitoring organizations. assessment and risk management techniques in industrial activities through the use of preventive approach to identify hazards , assess and control safety - health risks unit is studied. in this study, risks and effects of abadan gas power plant were studie...

Maintenance has been acknowledged by industrial management as a significant influencing factor of plant performance. Effective plant maintenance can be realized by developing a proper maintenance strategy. However, selecting an appropriate maintenance strategy is difficult because maintenance is a non-repetitive task such as production activity. Maintenance also does not leave a consistent trac...

With the growing worldwide awareness of environmental protection and sustainable development, green purchasing has become an important issue for companies to gain environmental and developmental sustainability. Thermal power is the main power generation form in China, and the green supplier selection is essential to the smooth and sustainable construction of thermal power plants. Therefore, sel...

Multiple criteria decision-making (MCDM) research has developed rapidly and has become a main area of research for dealing with complex decision problems. The purpose of the paper is to explore the performance evaluation model. This paper develops an evaluation model based on the fuzzy analytic hierarchy process and the technique for order performance by similarity to ideal solution, fuzzy TOPS...

The determination of the value of sea area used for port transportation involves the distribution of economic interests between the Chinese government and the users of sea areas. This paper builds an evaluation index system for the value of port transport sea areas. It is the first of its type to introduce the multiple regression weighting TOPSIS method (Technique for Order Preference by Simila...

Considering the difficulty and complexity involved in choosing an agricultural aircraft, it is proposed to rank agricultural aircraft based on linguistic evaluations of their qualities. Aiming this, it is used an algorithm based on the Analytical Hierarchy Process (AHP) method and in the Technique of Order of Preference by Similarity to Ideal Solution (TOPSIS). The linguistic parameterization i...

this paper proposes a method for ranking decision making units (dmus) using some of the multiple criteria decision making / multiple attribute decision making          (mcdm /madm) techniques, namely, interval analytic hierarchy process (iahp)          and the technique for order preference by similarity to an ideal solution (topsis).          since the efficiency score of unity is assigned to ...

Menjaga kebersihan tangan merupakan salah satu kewajiban dalam mengantisipasi penyebaran virus Covid-19. Banyak produk sudah ditawarkan agar pengguna dapat mencuci dengan aman dan nyaman, satunya wastafel. Tujuan penelitian ini dilakukan adalah menentukan vendor yang menjadi alternatif terbaik dari 5 untuk pembuatan Wastafel Injak Portabel di Kabupaten Dairi menggunakan metode Weighted Product ...

As an important part of daily economic activities, freight transportation produces various pollutions during the process, which will have a negative effect on sustainable development environment. In this paper, entropy weight technique for order preference by similarity to ideal solution (TOPSIS) combination method was used specific calculations, in judge whether is environmentally sustainable....
