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...

To improve the seedling-picking efficiency of vegetable transplanter and reduce damage rate seedling pot, a reciprocating device driven by full air pressure was designed. In this paper, structure working principle pneumatic are introduced. Through mechanical analysis between claw parameters such as stroke driving force clamping cylinder were determined. According to action sequence mechanism, w...

“First, the order picking then the stock planning – In the order picking area the most stuff is usually employed. Here the customer service and the logistics quality are decided. The highest costs incur here.” [5] The planning of an order picking system is characterized by the complexity of the system. All attempts to standardize the planning process failed so far. The aim of two research proje...

A footwear business is one of highly competitive markets. Footwear businesses must continuously improve three main key performance measures namely quality, cost and lead time. The case study is one of footwear businesses in Thailand. As customer demands are fragmented, the company needs to offer different products to serve customers’ satisfaction. Customer orders are then small quantities, but ...

A unique controlled field experiment investigates order picking performance (in terms of productivity and quality). We examined three manual picker-to-parts order picking methods (parallel, zone, and dynamic zone picking) under two different incentive systems (competitionbased versus cooperation-based) for pickers with different regulatory foci (prevention-focus versus promotion-focus). The stu...

OBJECTIVE Despite the substantial distress and impairment often associated with skin picking, there currently is only limited research examining various phenomenological aspects of this behavior. The present research contributes to the existing literature by investigating phenomenological variables related to skin picking, such as family involvement, anxiety, depression, and the emotional conse...
