In this paper, a mixed-integer linear programming model is proposed to integrate batch picking and distribution scheduling problems in order to optimize them simultaneously in an order picking warehouse. A tow-phase heuristic algorithm is presented to solve it in reasonable time. The first phase uses a genetic algorithm to evaluate and select permutations of the given set of customers. The seco...

The picking robot arm is scheduled to complete picking tasks in the working space, to overcome the shaking vibration to improve the picking stability, its movement should follow specific consistence trajectory points. Usually we should give definite multiple feature picking points, map their inverse kinematics to the joint space, establish motion equation for the corresponding point in the join...

Unilateral nevoid telangiectasia syndrome (UNTS) can be classified into two major categories: congenital and acquired. There have been reports showing an increase in skin estrogen and progesterone receptors in patients with this syndrome. We report a male patient with acquired unilateral nevoid telangiectasia syndrome without any associated physiological or pathological conditions.<...
