The article considers the solution of optimization problems of development design. The statement of the problem is multi-criteria optimization of given development design. The main selected criterion is electromagnetic compatibility (EMC). A mathematical model of the problem is constructed. To solve this problem, the article proposes a modified algorithm of colony bees (Algorithm Bee Colony) and differential evolution (DE) with hybridization by numerical methods for representing the initial solution. As a modification of the proposed approach, global and local improvements are introduced. In the developed hybrid algorithm, the search of solutions is also performed in the vicinity of various solutions, which avoids falling into local optima. A computational experiment was carried out on test benchmarks. The results of the researches show that the developed hybrid approach allows to quickly receive more effective decisions. The obtained results are on the average by 7 % better than the standard ABC algorithm, which indicates the effectiveness of the developed approach. The BCA lies within the range O(nlogn)-O(n2).

Key words: design engineering; optimization; electromagnetic compatibility; Algorithm of the bee colony (Algorithm Bee Colony); Differential evolution (DE); Numerical methods.
