Abstract: For the purpose of improving the utilization of semisubmersibles such as oil rigs in random seas, an optimal design method is proposed to seek optimal forms with minimum motion against sea ...

Abstract: A computer-aided planning method is proposed to design pump and piping systems used for the tanker’s oil unloading process. The following two planning models are combined hierarchically for the ...

Abstract: An expert system is developed for engineering design based on an object-oriented knowledge representation concept. The design process is understood as determining design variables and their ...

Abstract: With the objective of developing a computer-aided design method to seek the optimal semisubmersible’s form, hierarchical relationships among many design objectives and conditions are investigated ...

Abstract: A multi-objective nonlinear optimal planning method is proposed to design thermal distribution systems used for district heating. The following three objective functions are considered which are ...

Abstract: A multiobjective optimization method is applied to a design problem of heat insulation for thermal distribution piping network systems. As the system’s multiple design objectives, the following ...

Abstract: A hybrid type approach to plant layout design is presented using a constraint-directed search procedure and a mathematical optimization technique. In layout design, a plant must be arranged to ...

Abstract: The influence of fuel cost on the operation is investigated for a gas turbine-waste heat boiler cogeneration plant by an optimal operational planning method. A planning method is first presented ...
