Application of the sustainable materials technology model

Purpose: The paper presents a possibility of the sustainable technology model to the materials technological processes galvanic treatment used. Design/methodology/approach: The article includes analysis and estimation of the nickel and chromium coated on the metal elements. To selection of the best solution (about the least negative environmental influence) simple genetic algorithm was used. Polyoptimization makes possible selection of the optimum solution in view of several criteria, especially environmental. Findings: The conclusion of the work shows a possibility connecting of sustainable technology model with multiobjective optimization. This approach gives basis to collection of many modernization variants and selection of the optimum variant. Research limitations/implications: The enlargement of quantity and kind of criteria (except environmental criteria, e.g. quality, efficiency, costs, etc.) can narrow down the area of proposed solutions selection. The problem is the suitable introduction of these criteria to objective function. Practical implications: The solution presented in the paper can apply in the industry to estimation and selection of a group technological processes which characterize different environmental influences. To modernization variants optimization, except genetic algorithms, can be used other methods of polyoptimization. Originality/value: The paper presents searching for optimum solutions of the technological proces modernization with regard to environmental criteria with polyoptimization used.
