We present a two-phase model for planning and scheduling of order picking processes. In many warehousing environments order picking processes are organized according to the pick&pack principle. Pickers must build stabile loads during the picking process under strict time constrains. A genetic algorithm with Pareto elitist-based selection has been developed for this multi-criteria optimization p...

In manual order picking systems, order pickers walk or ride through a warehouse in order to collect items requested by customers. The performance of such a system is significantly dependent on its layout which determines the lengths of the order pickers’ tours and the corresponding picking times. Whereas for classic warehouse layouts all picking aisles are arranged in parallel to each other, in...

The rapid, stable, and undamaged picking of small-sized spherical fruits are one the key technologies to improve level intelligent robots reduce grading operations. Cherry tomatoes were selected as research object in this work. Picking strategies two-stage “Holding-Rotating” finger-end grasping determined. end-effector was designed separate fruit from stalk based on linear motion constraint par...

various studies suggest that selective serotonin reuptake inhibitors (ssris) may be useful in treating pathological skin picking (psp). this study sought to assess effectiveness of citalopram in comparison with placebo in treating psp. forty five individuals with psp were recruited in a four-week, randomized clinical trial of citalopram (20 mg/day) in comparison with placebo. study measures ass...

We present a numerical exploration of contact transitions with the fingertip. When picking up objects our fingertips must make contact at specific locations, and-upon contact-maintain posture while producing well-directed force vectors. However, the joint torques for moving the fingertip towards a surface (tau(m)) are different from those for producing static force vectors (tau(f)). We previous...
