Abstract | There are many optimization problems in engineering fields, including shipbuilding. To solve such problems, a non-linear optimization program is developed in this study. The developed program consists of two modules; a non-linear optimization library “EzOptimizer” and a pre-compiler “EzPreCompiler” for the library. The “EzOptimizer”, which is written in C++ language, includes a number of optimization algorithms, such as the method of feasible directions (MFD), sequential quadratic programming (SQP), sequential linear programming (SLP), genetic algorithm (GA), multi-objective programming, linear programming, etc. In addition, the “EzOptimizer” includes a method, which is referred to a “hybrid optimization method”, for combining local and global optimization algorithms such that their drawbacks can be overcome, thus permitting the use of the salient features of the two algorithms. The “EzPreCompiler” is a type of interpreter for the “EzOptimizer”. The “EzPreCompiler” supports the keyword recognition method, and converts keywords of an input file into a C++ source file that are required for using the “EzOptimizer”. To evaluate the efficiency of the developed program, it was applied to various optimization problems in shipbuilding and the results show that it is applicable to a wide range of optimization problems. |
