1. Multi-Objective Cooperative Paths Planning for Multiple Parafoils System Using a Genetic Algorithm
ABSTRACT In large-scale natural disasters and military supplies, multiple parafoils are more capable of performing actual tasks. The cooperative paths planning for multiple parafoils with different initial positions and headings is an important step in multiple parafoils airdrop, which has to satisfy multiple objectives, namely, parafoils can’t collide wit

3. Multi-objective Optimization Method For Repeat Ground-track Orbit Design Considering the Orbit Injection Error
ABSTRACT: Considering the adverse effects of orbit injection error, a novel repeat ground-track orbit redesign approach is proposed to reduce the fuel consumption caused by the orbital maneuvering from the injection orbit to the nominal orbit. By introducing the performance indexes of revisiting accuracy and orbit injection maneuvering fuel consumption, the

9. An integrated approach of sustainable procurement and procurement postponement for the multi-product, assemble-to-order (ATO) production system
Abstract Postponement strategy is mainly used to handle the perceived variety and actual variety of product in the most cost effective way. However, postponement strategy has never been used by researchers in procurement to reduce cost and to enhance overall flexibility of the process. This paper gives a new concept of postponement, called procurement postpo
