This work addresses the large-scale crude scheduling problem of a real case refinery importing various types of crude oil from two ports via long-distance pipelines. We employ a spatial-based decomposition approach to construct a two-stage model of the practical refinery operations. During the first stage, the refinery plant is treated as a single aggregated demand node to simplify the port sub-problem...
There are many factors affect the warship life cycle cost (LCC), the importance of every factor is different, and the relationships between factors are correlated. In order to establish the precise LCC model, the principal components regression (PCR) and partial least squares regression (PLSR) are proposed to reduce the correlativity between factors which affect the modeling of LCC. However, the components...
To accomplish the optimization for bus priority on large scale road network, the distributed traffic simulation (DTS) system with the architecture based on service oriented architecture (SOA) and multi-agents is designed. In the DTS system, compound simulation models are adopted to accelerate the simulation. Simulation road network is persisted in Oracle database through object-relation mapping (ORM)...
Bats can easily pick up an individual prey among multiple targets by using the echoes of the emission that overlapped in time. So far, the process produced by the batspsila echolocation system is not completely understood. A computational Model for batspsila echolocation based on mammalian auditory system is proposed and analyzed in this work. This model is a description for the signal processing...
