The MINLP optimization approach to structural synthesis. Part III, Synthesis of roller and sliding hydraulic steel gate structuresKravanja, Stojan ; Kravanja, Zdravko ; Bedenik, BrankoPart III of this three part series of papers describes the synthesis of roller and sliding hydraulic steel gate structures performed by the Mixed-Integer Non-linear Programming (MINLP) approach. The ... MINLP approach enables the determination of the optimal number of gate structural elements (girders, plates), optimal gate geometry, optimal intermediate distances between structural elements and all continuous and standard crossectional sizes. For this purpose, special logical constraints for topology alterations and interconnection relations between the alternative and fixed structural elements are formulated. They have been embedded into a mathematical optimization model for roller and sliding steel gate structures GATOP. GATOP has been developed according to a special MINLP model formulation for mechanical superstructures (MINLP-MS), introduced in Parts I and II. The model contains an economic objective function of self-manufacturing and transportation costs of the gate. As the GATOP model is non-convex and highly non-linear, it is solved by means of the Modified OA/ER algorithm accompanied by the Linked Two-Phase MINLP Strategy, both implemented in the TOP computer code. An example of the synthesis is presented as a comparative design research work of the already erected roller gate, the so-called Intake Gate in Aswan II in Egypt. The optimal result yields 29.3 per cent of net savings when compared to the actual costs of the erected gate.Vir: International journal for numerical methods in engineering. - ISSN 0029-5981 (43, No. 2, 1998, str. 329-364)Vrsta gradiva - članek, sestavni delLeto - 1998Jezik - angleškiCOBISS.SI-ID - 3937558
