This paper addresses a special kind of container loading problem with shipment priority. We present a tree search method, which is based on a greedy heuristic. In the greedy heuristic, blocks made up of identical items with the same orientation are selected for packing into a container. Five...

Purpose – The purpose of this paper is to present a case‐based system for offline automatic programming in robotic assembly production. This system can reuse past learned robot programs to generate programs for new assembly tasks. Design/methodology/approach – The approach used in this...

In the Industry 4.0 era, advanced analytical tools are essential for progressing with digital transformation, especially within complex socio-technical systems. However, the growing complexity of these systems in manufacturing impedes system improvement, and traditional analytical methods...

Zeolite supported transition metal catalysts have been proved highly efficient for hydrodeoxygenation (HDO) of bio–oil, but always faced decreased catalytic activity due to the aggregations of metal active sites and the restricted diffusion properties by microporous zeolite. In this work,...

Zeolite supported base metal catalysts were deemed as one of the most efficient catalysts for hydrodeoxygenation (HDO) of bio–oil, but facing the activity sacrifice by the metal aggregation. In this study, uniform Ni nanoparticles encapsulated in ZSM–5 zeolites (Ni@ZSM–5s) were synthesized...
