In managerial and economic applications, there appear problems in which the goal is to simultaneously optimize several criteria functions (CFs). However, since the CFs are in conflict with each other in such cases, there is not a feasible point available at which all CFs could be optimized simultaneously. Thus, in such cases, a set of points, referred to as 'non-dominate' points (NDPs), will be...

In order to solve the problem that design constraints of conjugated straight-line internal gear pair are unclear, designing and checking pairs requires repeated trial error. By analogy with involute pair, basic parameters were clarified. Based on mathematical model given according engagement theory geometrical relations tooth profile. The calculation formula constraint contact ratio deduced kin...

Abstract Capacity prediction of surface mount production lines is important for improving productivity, dynamic scheduling, and optimizing structure. An integrated mutual information-cuckoo search-extreme learning machine (MI-CS-ELM) model proposed the impact nonlinear high-dimensional features surface-mounted on capacity. Firstly, affecting capacity are ranked based information method, predict...
