the purpose of this paper is multi-objective optimization of refrigeration cycle by optimization of all components of the cycle contains heat exchangers, air condenser, evaporator and super-heater. studied refrigeration cycle is compression refrigeration cycle of unit 132 third refineries in south pars that provide chilled water for cooling refinery equipment's. cycle will be performed by ...

the development of multiple criteria decision making techniques is to provide the possibility of using multiple criteria in decision making problems. multi-criteria decision making problems primarily relate to choosing the best option among several available options and according to some indicators. one of the major issues in this regard is to determine the importance weights of decision criter...

In this study, the performance of the algorithms of whale, Differential evolutionary, crow search, and Gray Wolf optimization were evaluated to operate the Golestan Dam reservoir with the objective function of meeting downstream water needs. Also, after defining the objective function and its constraints, the convergence degree of the algorithms was compared with each other and with the absolut...

Although crisp data are fundamentally indispensable in the conventional linear programming technique for multidimensional analysis of preference (LINMAP), the observed values in the real-world problems are often imprecise or vague. These imprecise or vague data can be suitably characterized by linguistic terms which are fuzzy in nature. LINMAP has been widely used to solve multi-attribute decis...

In the first part (Part I) of this study, a novel fluidized bed reactor was modeled mathematically for methanol synthesis in the presence of in-situ water adsorbent named Sorption Enhanced Fluidized-bed Reactor (SE-FMR) is modeled, mathematically. Here, the non-dominated sorting genetic algorithm-II (NSGA-II) is applied for multi-objective optimization of this configuration. Inlet temperature o...

• Proposed a novel progressive Four-Hierarchy method to design the ORC power plants. Effective integration of modelling, optimizing, scheme comparing and decision-making. Three-level fuzzy decision is developed for evaluating Pareto set point. All-around view given based on Taylor diagram get Pareto-optimal solution. Quantitative evaluation achieved schemes using method. In this paper, practica...

Although various investigations of Atkinson cycle have been carried out, distinct output power and thermal efficiencies of the engine have been achieved. In this regard, thermal efficiency, Ecological Coefficient of Performance (ECOP), and Ecological function (ECF) are optimized with the help of NSGA-II method and thermodynamic study.  The Pareto optimal frontier ...

Due to increased demands of production capacity and higher quality requirements, industries are automating at a fast pace. Industrial robots an important component the industrial automation ecosystem. However, selection appropriate is challenging task due sheer number alternatives present their varied specifications. The various characteristics or attributes that need consideration before optim...

Based on the square heat-generation body (HGB) with “arrow-shaped” high-thermal-conductivity channel (HTCC) model established in previous literature, we performed multi-objective optimization (MOO) maximum temperature difference (MTD) minimization and entropy-generation rate (EGR) as objectives for its performance. Pareto frontiers optimal set were obtained based NSGA-II. TOPSIS, LINMAP, Shanno...
