Improved method of group decision making in expert systems based on competitive agents selection

An evolutionary method for solving the traveling salesman problem in the field of pharmacy business by optimizing the work of the drug delivery device is proposed in this paper. Modifications of three methods of initialization of the initial population of the genetic algorithm are developed. The software implementation is proposed to solve the problem of a sales-man in the pharmacy business by optimizing the process of drug delivery, using modified evolutionary methods. Unlike existing methods, the modified version of the evolution method allows to choose the original method of population initialization when solving the problem of traveling salesman, which, in turn, allows to generate more adapted chromosomes (chromosomes with better values of fitness functionality) at the stage of initialization and thereby improve the results algorithm. It is also possible to graphically monitor the process of solving the seller's problem, get the result in text and graphic forms. The principles of objectoriented programming, namely the use of classes, the principle of data encapsulation and inheritance, were used when writing the program. UML diagrams of classes, sequences, activities, states and cooperation were used to visualize the structure and functional relationships of the modules of the developed software.

“…Для забезпечення надійної роботи струмопровідних систем залежно від характеру навантаження та коефіцієнта потужності мережі необхідно точно визначити параметри шин (активний і реактивний опір) [20]. На сьогоднішній день існують емпіричні методи оцінки параметрів тролеїв шинопроводу, які базуються на використанні схемо-технічних методів моделювання [21,22]. Ці методи мають велику кількість припущень і обмежень внаслідок чого похибка при визначенні параметрів шин може досягати 30-50 % [23,24].…”

Modern workshop power supply systems can have a significant length. Therefore, their parameters and electrical characteristics have a significant impact on power quality, operation modes of electrical consumers and energy efficiency of technological processes. Available in engineering practice methods of calculation of parameters and characteristics of bus ducts are based on methods of circuit modeling. Circuit parameters are usually determined on the basis of generalized equations. These equations are derived from a number of assumptions, which limits the scope of their use. Alternative methods, based on empirical dependencies, can be used to calculate the electrical parameters and characteristics based on field modeling. Thus, the paper proposes a mathematical two-dimensional field model of electromagnetic processes in the frequency statement of the problem, allowing with high accuracy and efficiency of numerical implementation to decompose electromagnetic processes in the active elements of the trolley busduct and for each relevant amplitude and frequency of the k-th harmonic current to determine the electromagnetic parameters. busduct with regard to their design features, nonlinearity of magnetic and electrical properties of materials, the skin effect, the blitz effect. A general analysis of active and inductive resistances of busduct phase trolleys depending on their shape, material and current harmonic spectrum is performed. The level of asymmetry of busbar parameters caused by proximity effects, surface effects, skin effects and other edge effects is given. It is found that in the presence of higher current harmonics, the parameters (active and reactive supports) of busbar trolley do not depend on the amplitude of k current harmonics, but depend only on their frequency. The level of voltage drop asymmetry for all forms of phase trolley busducts is caused by the asymmetry of their parameters. Among investigated L, W-, I-, U, X-forms of bus duct trolleys it was found that the most optimal form of steel and copper bus duct trolleys is the angular form of trolleys (L-form), which provides the least increment of active and reactive resistance of bus duct trolley, current harmonics, as well as the minimum level of their asymmetry between phases of bus duct trolleys.
