Use of Criterial Synthesis and Analysis for Modernization of Objects of Machine Building Production

Abstract

Modernization problems of known equipment now are actual enough for different branches of the mechanical engineering. Therefore, a lot of time and efforts is spent on rationalization and automation of synthesis and analysis of modernized objects. The known methods and the software tools for synthesis and analysis of schemes of different equipment and technologies for the machine building production are not enough universal and labor-intensive, because a significant part of work for their realization is fulfilled by high-qualified specialists without of use of computers. There is an improved method of criterial synthesis and analysis elaborated in this article. This method allows with relatively small expenses of time to receive effective variants of different equipment with consideration of the all main initial conditions and parameters and with a possibility of determination with help of simple formulas of the most important criterions of their evaluation for founded selection of the most effective variant. Under realization of the proposed method as main initial parameters of the projected equipment for machining, loading-unloading or transportation are used: equipment destination, its admissible dimension, mass, working capacity, cost, power-consuming, accuracy. Taking in consideration these initial parameters at the next stages are selected admissible variants of modernization. Final evaluation and selection of the most prospective variants are made under criterions of admissible dimension, mass, working capacity, cost, power-consuming, degrees of standardization, unification and automation. At basis of the proposed method can be elaborated a computer program of automated synthesis and analysis for high-effective modernization of modern equipment and technologies for the machine building production.

Systems of Automatic Control for Hydroponic Technological Complexes

“…Realization of such complex automation is possible on basis of a corresponding technical level of all enterprises as elements of these technological complexes (plant-growing, accessory and transport manufacturers), their main and auxiliary equipment, logistic and control systems, software. There are need close relations and effective interaction between of all enterprises of the technological complex with using of a specified computer program for automatic synthesis of possible variants of functioning of a technological complex for fulfilment of an order or a block of orders, their analysis by main efficiency criterions, foundation and selection of a most rational variant [4,5,6].…”

“…One more important source of information the data about of hydroponic technological complexes of the region (configuration of their production capacities and equipment, specialization, technological and operational characteristics, extent of loading of the capacities for the moment of time, availability of the capacitiessee more detailly lower). There can be facilities of different production complexes and various enterprises [4,5,6]. The data about of equipment of the hydroponic technological complexes and logistic enterprises (suppliers and transport companies) form a data base 2 (DB2).…”

“…So, the number of variants of an order's fulfilment (variants of combinations of equipment of hydroponic technological complexes, suppliers, transport companies) may be quite large. The synthesis and analysis of this number of the variants with consideration of the several main criterions can be realized only under utilization of the corresponding computer program [4,5,6].…”
