Abstract
The problem of optimization of industrial processes consisting of a series of forming operations which define the production cycle, is considered in the paper. Optimization of production cycles is a hard task due to the large number of control variables, mutually exclusive or contradictory objective functions formulated at the production stages and numerical complexity of the process models. Application of sensitivity analysis is one of the solution to reduce the problem. Various methods of global sensitivity analysis were presented in the paper. The procedures were applied to the selected industrial processes: the final part of the manufacturing chain for anchors and controlled cooling of rails. The most important parameters of the processes were determined. The sensitivity analysis results were presented and discussed in the paper.
