An improved genetic algorithm for multi-floor facility layout problems having inner structure walls and passages
TL;DR: An improved genetic algorithm is proposed to derive solutions for multi-floor facility layouts that are to have inner structure walls and passages and is applied to the multi-deck compartment layout problem of the ship with the computational result compared with theMulti- deck compartment layout of the actual ship.
Journal ArticleDOI
Determination of the optimal operating conditions of the dual mixed refrigerant cycle for the LNG FPSO topside liquefaction process
TL;DR: A mathematical model of the DMR cycle was formulated in this study by referring to the results of a past study that formulated a mathematical models of the single mixed refrigerant (SMR) cycle using a hybrid optimization method that consists of the genetic algorithm and sequential quadratic programming (SQP).
Journal ArticleDOI
Estimation of hydrodynamic coefficients for an AUV using nonlinear observers
TL;DR: In this paper, the hydrodynamic coefficients are estimated using two nonlinear observers -a sliding mode observer and an extended Kalman filter -and evaluated by comparing the estimated coefficients obtained from the two observer methods with the values as determined from the planar motion-mechanism test.
Journal ArticleDOI
Dynamic response simulation of a heavy cargo suspended by a floating crane based on multibody system dynamics
TL;DR: In this paper, the dynamic response simulation of heavy cargo suspended by a floating crane is performed and the dynamic equations of the motions of the floating crane and the heavy cargo must be considered by the coupled equations.
Journal ArticleDOI
Development and application of an intelligent welding robot system for shipbuilding
TL;DR: In this paper, the authors describe the design, integration, simulations, and field testing trials of a new type of welding robotic system, the RRXC, which is composed of a 6-axis modularized controller, a 3P3R serial manipulator, and an auxiliary transportation device.
