	Engineering developments that increase efficiency are promoted in all industrial sectors. The type of problem to which this technology is applied can be formulated as an optimization problem, that is, the problem of "finding the best solution to the objective function subject to the given constraints." The approach to finding a solution is to apply an optimization technique based on the features of the system. However, in the field of industrial applications, it is becoming very difficult to use conventional optimization techniques, since such systems are becoming increasingly large scale and complex, with rapid changes in the surrounding environment and increased uncertainty. In this area, the applied research has been actively performed in parallel with the development of the algorithm, and in some fields, benchmark problems have been created. Generally, the conventional benchmark problems are not based on practical problems in industrial fields. Therefore, those methods, which can obtain good results for conventional benchmark problems, may not obtain good results for practical problems. This technical report reviews the conventional benchmark problems and develops novel benchmark problems for industrial applications based on practical problems in various industrial fields. As a compilation of these activities, some benchmark problems and examples of solutions for industrial applications are presented. The problems include "water supply pump planning", "automatic picking system operation planning", "series-parallel switching of photo-voltaic modules" and "energy plant operation planning".
