Computer-aided design (CAD) is one of the actual trends of technological pre-production development which provides high quality and efficiency of design projects. Designing of technological process (TP) assisted by CAD systems allows in a short time to perform preparatory stages before launching new models into production.
The main stages of clothes manufacturing TP are the following: parts processing and their joining into a garment. The stage of parts processing assumes parallelism of details and units treatment. The garment units are separate parts of the garment according to construction and technological processing (front and back panels, collar and etc.).
During the stage of parts joining the garment details are joined to each other. For example the constructive elements (CE) of clothes with waistbands joining stage are side, step, middle cuts, top and hem cuts of the product. Determination of the CE sequence at the stage of joining requires analysis of all elements links, and this considerably complicates the process of the technological sequence formation.
