Intelligent Sea Transportation System Postoptimal Analysis

A procedure for the ship dynamic positioning postoptimal analysis in Intelligent Sea Transportation System Optimization is proposed. The dynamic positioning control system design is based on the optimal constrained covariance control (OC3). In that way some disadvantages of the classical optimal control technique are avoided. When the sensitivity of solutions to desired system performances is performed, then it can be shown that under particular circumstances, a slight change of desired system performances could significantly improve the optimal solution value. Namely, a slight relaxation of desired system position accuracy could result with significant energy savings. The presented numerical example illustrates some benefits of the proposed approach.
