  abstract     = {{The aerospace sector is characterized by long product life cycles and a need for lightweight design. Additive manufacturing is a technology that produces parts layer by layer and thus enables the manufacturing of any complex parts at nearly no extra costs. A topology optimization enhances the part’s
performance for their special purpose. The results are often complex bionic structures that cannot be produced with conventional manufacturing technologies. The paper analyzes how the high potential of this technologycan be applied to aerospace parts. A topology optimization will be conducted for an aircraft part explaining the crucial points and a life cycle analysis examines the achieved sustainable improvements for the aircraft’s life cycle.

  abstract     = {{Order picking has long been identified as the most labor costly and intensively activity in warehouse management. The orders from the customers need to be fulfilled tightly and timely. In order to keep the required high service level, the warehouse has to increase the picking productivity under the constraints of limited capacity. This paper concerns a man-togoods order picking system, in which the order pickers have to drive with a pallet jack to the storage locations. Considering that the orders are mostly small orders which consist of less lines, it is efficient to combine severalsingle customer orders into one picking order. Under this circumstance, this paper intends to answer the question of how customer orders should be grouped into picking orders with the aim of minimizing the total travel length through the warehouse. Consequently the productivity of the order picking system can be improved. An optimization problem for order batching is introduced. The optimization method of order batching is then proposed. Based on the simulation of different scenarios of incoming orders, it can be concluded that the developed method is effective in improving the productivity of the concerned order picking system.

  abstract     = {{The trend of increasing technological complexity of machines mainly correlates with the integration of additional functions in machines. Increasing functionality  of  the  machines  leads  to  an  increased  number  of  control  
elements, which limits the clarity of the machine operation and leads to higher cognitive demands in the machine operation. Due to the growing functional range of production machines the demand of usability  for  the  operating  systems  continues  to  grow.  The  selection  and design  of  icons  for  the  identification of controls  contributes  significantly  to usability, especially for intuitive operation of production machines.  
The  aim  of  this  study  is  to  investigate  the  intuitive  usability  of  production machines,  to  consider  its  use  of  graphical  elements  (icons)  and  to  derive recommendations  for  a  demand-oriented  selection  and  design  of  icons.  To achieve  this  goal,  laboratory  studies at  five  modern  production  machines (laser  sintering  machine,  CNC  universal  lathe,  plastic  injection  molding machine,  laser  processing  machine,  woodworking  machine)  -  each  with different operating concept - were performed. The  results  of  the  study  show  that  the  used  symbols  in  the  examined machines  are  only  limited  self-explanatory  and  intuitive,  and  thus  have significant deficits for easy and intuitive operation. Especially the combination of screens and electronic keys or switches was often criticized and leads to uncertainty in the operation. As a result, recommendations for the design of icons on production machines are given. }},
