The work presents the description of a method for performing optimized calculations with the use of the genetic algorithm method performed on computers paralleled in a cluster. It defines the scope of electromagnetic calculations which must be performed in order to determine the objective function. It also provides sample factors describing the quality of paralleling the calculation process.
The paper presents the procedures of tolerance analysis and optimization of linear periodically time-variable circuits, based on the frequency symbolic method and realized by the system of functions MAOPCs in an environment MATLAB.
Mathematical models which adequately combine their technological parameters with indicators of treatment quality have been designed for the cavitation cleaning processes of sewage from organic admixtures. Water of brewing, milk processing industry and public water use it is considered as sewage.
The problems of organization and support management in organizations that implement their activities in the form of projects were considered, as well as the main approaches to managing a portfolio of projects, two-step procedure for drawing portfolio, taking into account both formal and informal aspects was proposed.
The article describes the design features of ranking websites in the global Internet, the analysis of the known systems and promotion resources was done and the internal and external factors of ranking were given. Possible schemes of Internet resources using the tools of link ranking were analyzed. We describe the main problems that arise when optimizing pages on the set of queries and give the scheme of splitting by keyword pages of the resource.
Problems of organization, planning and maintenance management in organizations that implement their activity in the form of projects are considered. The critical analysis of the operation in this environment was carried out, major shortcomings and methods of overcoming them are pointed out.
This paper belongs to the field of systems engineering and is aimed at improving the qualitative indices of information technologies or systems with multidimensional characteristics (e.g. vector data coding design) with respect to reliability, precision and other significant operating characteristics of the systems based on the combinatorial configurations theory, namely the principle of optimal cyclic proportions (OCP).
In the paper considered the models of project portfolio’s formation and the allocation of resources between the portfolio projects under uncertainty, their advantages and disadvantages, the impact of organizational structures and modern software development technologies to reduce the uncertainty level, substantiated the necessity to use imitation to obtain decisions on planning in multi-project environment, offered structure of the simulation model.
This paper belongs to the field of systems engineering and is aimed at improving the qualitative indices of vector data information technologies (e.g. 2D vector data coding design) with respect to reliability, precision and other significant operating characteristics of the systems based on the combinatorial configurations theory, namely the Ideal Ring Bundles (IRB)s.
The article features revealed pricing for machine building products. The general approach to modeling the process of pricing for machine building products within the parameters of the demand for goods produced using this product. The building model performance optimization criterion prices and volumes of sales machine building company. Established the possibility of using performance optimization criterion prices for machine building products to address the task of selecting the best varieties of products.
