“…Para [9] usaron el análisis de sensibilidad global para identificar los parámetros geométricos más influyentes que afectan el costo total de los STHE con el fin de reducir el tamaño del problema de optimización y llevar a cabo la optimización de los parámetros influyentes de los SYHE desde el punto de vista económico mediante la aplicación del algoritmo de búsqueda armónico. Los autores habían considerado la minimización de los costos de capital y los costos de operación como una función objetivo.…”

Shell and Tube Heat exchangers (STHEs) are the most common type of heat exchangers. They are applied in numerous industrial installations. The minimization of the costs of these heat exchangers is a key goal for both designers and users. The design of this type of heat exchanger involves complex processes, including selection of the geometrical and operating parameters. The traditional design approach of Shell and Tube Heat Exchangers consists of the evaluation of a number of different exchanger geometries to identify those satisfying a requirement of heat and a set of geometric and operational constraints. However, this approach is slow, inaccurate and does not guarantee an optimal solution. In this paper, different evolutionary algorithms to optimize STHEs economically are analyzed and applied, including the particle swarm optimization, genetic algorithms and mixed ant colony optimization, this last one developed by the authors. As objective function the minimization of total annual cost was considered. For optimization were considered as independent design variables the inside diameter of the shell, the outer pipe diameter and spacing between the baffles. They were also considered for optimizing two patterns or arrangements of tubes, in a triangle and a square. An example of three case studies of optimization of heat exchanger is presented. The results of the optimization using the mixed ant colony technique are compared with those obtained using particle swarm and genetic algorithms.Key words: Heat exchangers, optimization, evolutive algorithms, ant colony.Minimización del costo de los intercambiadores de calor de tubo y coraza mediante algoritmos evolutivos RESUMEN Los intercambiadores de calor de tubo y coraza (ICTC) son el tipo más común de los intercambiadores de calor. Los mismos se aplican en numerosas instalaciones industriales. La minimización de los costes de estos intercambiadores de calor es un objetivo clave tanto para los diseñadores como para los usuarios. El diseño del intercambiador de calor implica procesos complejos, incluyendo la selección de los parámetros geométricos y parámetros de funcionamiento. El enfoque tradicional de diseño para los intercambiadores de calor de tubo y coraza consiste en la evaluación de un determinado número de geometrías diferentes del intercambiador para identificar aquellas que satisfacen un requerimiento de calor y un conjunto de restricciones geométricas y operacionales. Sin embargo, este enfoque es lento, poco preciso y no garantiza una solución óptima. En el presente trabajo se analizan y aplican diferentes algoritmos evolutivos para optimizar económicamente los mismos, entre ellos la optimización con enjambre de partículas, por algoritmos genéticos y por colonia de hormigas mixto, este último desarrollado por los autores. Como función objetivo se consideró la minimización del costo total anual. Para la optimización se consideraron como variables independientes de diseño el diámetro interior de la coraza, el diámetro exterior del tubo y el espaciami...

“…more applications include the solution of Sudoku puzzles [88], musical composition [89], timetabling and room allocation for university courses [25], optimization of a milling process [90], and the selection of land parcels for ecological conservation (a MCSP) [65]. Fesanghary et al [56] compared IHS and GA for the optimal design of a shell and tube heat exchanger, which included both annualized capital and operating costs. The optimal operation of a system of cogeneration (combined heat and power) plants was studied in [93].…”

Harmony Search (HS) is a meta-heuristic algorithm which bases its operation on the musical improvisation process. Recently, HS has become a popular algorithm in the evolutionary computation fielddue to its superiority to many other algorithms. As a consequence, in this paper, HS algorithm, its improvements and applications in many fields, such as operations research and computer science, are discussed and analyzed. The survey investigates the difference between HS algorithms as well as its applications. To add to this, several future improvements are suggested.

“…For example, in [6], the Sobol method is applied in optimization of shell and tube heat exchangers; the non-influential geometrical parameters which have the least effect on total cost of tube heat exchangers are identified. In turn, in [7], a new GSA based algorithm for the selection of input variables of neural network is proposed.…”

Abstract-In this article, the problem of determining the significance of data features is considered. For this purpose the algorithm is proposed, which with the use of Sobol method, provides the global sensitivity indices. On the basis of these indices, the aggregated sensitivity coefficients are determined which are used to indicate significant features. Using such an information, the process of features' removal is performed. The results are verified by the probabilistic neural network in the classification of medical data sets by computing model's quality. We show that it is possible to point the least significant features which can be removed from the input space achieving higher classification performance.
