An optimization method of aircraft periodic inspection and maintenance on the zero-failure data analysis is proposed to effectively solve excessive maintenance in this work, and decrease aircraft unserviceable time. This method includes optimization object analysis, failure distribution recognition, zero-failure data analysis by confidence limit optimal estimate and nonlinear programming solving failure...
As a key structure in an aircraft, rudder is employed to steer the flight vehicle under the instructions of center control unit. There are three main components in rudder: actuator, transmission, and control surface. Power is usually transmitted from the actuator to the control surface via the transmission. To some degree, the performance such as the efficiency and rigidity of rudder is directly determined...
Chaotic Ant Swarm is a recently new and promising algorithm of Optimization Problem based on the chaotic theory and foraging food processing of ants. This paper proposes a Multi-Objective Optimization version of CAS, named MOCAS, by changing the colony behavior organization. The proposed algorithm also introduced a re-distribution operation that ensures the uniform distribution of final result. We...
In this paper, we are interested in the Robust Wounded Transfer Problem (RWTP) in the background of large-scale emergencies such as typhoons, floods, earthquakes, droughts and so on. We introduce the theory of robust discrete optimization, and formulate the problem as a multi-point transportation model with multi-type vehicles, based on an absolute robustness criterion to minimize the maximum total...
In this paper, we are interested in the Robust Sensor Placement Problem (RSPP) in municipal water networks. As the contamination source and time are rather random and almost impossible to forecast, we aim to minimize the maximum population exposed over all contamination scenarios by placing a limited number of sensors into the network. We formulate a mixed-integer program model based on an absolute...
In this paper, we are interested in obtaining robust solutions to the Wounded Transfer Problem based on an absolute robustness criterion, in the background of large-scale emergencies such as typhoons, floods, earthquakes, droughts and so on. We firstly describe the related methodology, and then introduce a min-max robust multi-point transportation model with multi-type vehicles to minimize the maximum...
