Multi-objective design for a new type of frame saw machine

A new type of frame saw machine with four-bar parallelogram linkage mechanism has been recently studied around the world. In this paper, an advanced model including 8 control parameters, 9 functional constraints and 9 objective functions was developed with a goal to interact and deal with inconsistencies among four stages within design process of this machine, such as concept, analysis, technology and multi-criteria decision-making processes. The last stage or the most important one was in fact a multi-objective optimization problem; in order to tackle with it the authors used a visual interactive analysis method (VIAM) with an application of single-objective optimization techniques. By using VIAM for three manufacturing scenarios, 28 Pareto optimal solutions have been determined; hence the designer is able to make a proper decision at every scenario. © TJPRC Pvt. Ltd.
