The efficient movement of raw materials within organizations is fundamental to maintaining the seamless progression production processes. However, these logistical operations can inadvertently compromise overall company efficiency, primarily due substantial time invested in transporting materials. This paper introduces an innovative mathematical model specifically designed optimize transport vi...

Abstract Remanufacturing includes disassembly and reassembly of used products to save natural resources reduce emissions. While assembly is widely understood in the field operations management, a rather new problem production planning control. The latter faces challenge high uncertainty type, quantity quality conditions returned products, leading volatility remanufacturing systems. Traditionall...

Unmanned Aerial Vehicles (UAVs) play increasingly important roles in many modern militaries. The proven success of the UAVs during the operations in Afghanistan and Iraq has created a demand for UAVs with varying functionalities and capabilities. UAVs are currently performing tasks and playing roles of the manned systems in many mission areas. Although UAVs are limited in meeting all the requir...

The human-machine function allocation (HFA) strategy of manned submersibles is an important factor that affects the reliability oceanauts. However, uncertainty HFA makes its optimization very complicated. To this end, a non-cooperative game-based method proposed, which transforms multi-objective model mental workload and situation awareness (SA) under into game forms mapping relationship. Menta...

In order to solve the structural damage problem of first generation large multi-rotor manned drones, present work has designed study vibration problems drones. On a small drone, laser meter verified reliability acceleration sensor measurement and found that circular shape carbon fiber arms have strong damping abilities, with strongest in Z-axis direction. To improve design second elliptical wer...

In a previous paper, a new scenario for human missions to Mars has been presented. It can be named the 2-4-2 concept. The idea is to minimize IMLEO and the payload on Mars with a crew of only two astronauts. There are two astronauts in each rocket at departure from Earth. They meet on Mars to form a team of four and the pairs are reconstituted for the return (2-4-2). In the previous study it wa...
