The objective of this paper is investigation of the optimization of manufacturing technology processes of large composite plastic products. One of the key problems is how to integrate computer-based product design and planning of the technological process. An optimization model is proposed to control and analyse the calculated technology planning route, optimal vacuum forming processes, the technology of post-forming operations (like trimming and drilling of slots and cut-outs) and strengthening and assembling operations. Finite element analysis and artificial neural networks are included in the model used in the study. A family of large composite plastic products together with the derivate products and their production technologies is designed using the proposed methodology.
