This paper proposed a multi-objective, multi-disciplinary design optimization and multi-attribute evaluation method for the manned lunar lander descent stage. A system model is established considering multiple disciplines such as propulsion, structure, trajectory cost. With goal of minimizing mass, cost maximizing velocity increment, overall scheme hybrid rocket motors was optimized by altering...

This paper presents a new method to address the Hybrid Assembly Line Balancing Problem with multiple objectives. The aim is to assign a set of tasks to workstations and select the assembly equipment or resource to perform each of them. The goal is to minimize the total cost of the line by integrating design (congestion, machine real cost...) and operation issues (cycle time, precedence constrai...

This article provides a starting point for developing methodology to successfully implement Industry 4.0 technology assembly operations. It presents novel multi-layer human-centred conceptual model in line with Lean philosophy which identifies the operator functions and relates them other production departments, identifying how they would be affected by incorporating new digital technologies. T...

The contribution presents a multi-agent technology in the domain of the air-traffic control of several autonomous aerial vehicles (manned as well as unmanned). The system has been validated mainly by the collision avoidance (CA) tasks. Several cooperative and non-cooperative CA methods have been integrated in the system to validate and compare their properties in the scalable experiments. The A...

For long duration, manned exploration to be cost-effective, it is necessary to automate routine manual operations. To enable such automated control, activity plans must coordinate the activities of the crew with other automated “agents” including robots, life support systems, and vehicle systems. An important challenge is assisting the crew in using automated planning software to construct and ...
