Assessment of assembly complexity of electronic units

The article is devoted to the complexity assessment of harvesting systems. The author considers peculiarities of assembly lines as production systems and the reasons for the constant growth of their complexity. Complex assembly systems are expensive to implement, run, control and maintain, while their complexity affects performance, quality and reliability. Thus, when designing any assembly system, one must look for compromises between its future operation features, its cost and its complexity. To do this, you need to be able to quantify the complexity. This study made it possible to classify the methods of complexity analysis and propose a model that allows quantifying, to some extent, the complexity of the assembly of electronic units and can be used to work with complex multi-subject lines. The study considers the complexity indicators for the operator`s work. To numerically assess the complexity indicators, it is proposed to use the Likert scale. It is assumed that further research should take into account the following issues. The assembly should be designed with consideration of the human factor and the interrelation of technological operations, tools and ergonomics. This is due to the fact that in manual and semi-automatic workplaces, the human operator plays the crucial part. The connection between ergonomics and complexity must be established using the utility function, methods of fuzzy logic, and computer experiments with a test dummy.
