This research focuses on the Hybrid Flow Shop production scheduling problem, which is one of the most difficult problems to solve. The literature points to several studies that focus the Hybrid Flow Shop scheduling problem with monocriteria functions. Despite of the fact that, many real world problems involve several objective functions, they can often compete and conflict, leading researchers to concentrate direct their efforts on the development of methods that take consider this variant into consideration. The goal of the study is to review and analyze the methods in order to solve the Hybrid Flow Shop production scheduling problem with multicriteria functions in the literature. The analyses were performed using several papers that have been published over the years, also the parallel machines types, the approach used to develop solution methods, the type of method develop, the objective function, the performance criterion adopted, and the additional constraints considered. The results of the reviewing and analysis of 46 papers showed opportunities for future researchon this topic, including the following: (i) use uniform and dedicated parallel machines, (ii) use exact and metaheuristics approaches, (iv) develop lower and uppers bounds, relations of dominance and different search strategiesto improve the computational time of the exact methods, (v) develop other types of metaheuristic, (vi) work with anticipatory setups, and (vii) add constraints faced by the production systems itself.

The design of a transformer must meet minimum requirements of efficiency and regulation, maximizing the power to be transferred per unit of mass or volume, and supports a well defined maximum elevation of temperature. Conflicting objectives lead to the employment of optimization methods in the transformer design. Multiobjective optimization problems (MOPs) consist of several competing and incommensurable objective functions. Recently, as a search and optimization technique inspired by nature, evolutionary algorithms (EAs) have been broadly applied to solve MOPs. Various EAs have been proposed for this purpose, and their usefulness has been demonstrated in several application domains of science and engineering. In this paper, we propose the unrestricted population-size evolutionary multiobjective optimization algorithm (UPS-EMOA) approach combined with chaotic sequences (CMOA). Our approach integrates the merits of both UPS-EMOA and chaotic sequences to improve the efficiency of the optimization procedure. Numerical results of transformer design optimization demonstrate the effectiveness of the proposed CMOA when compared with the UPS-EMOA approach to preserve the diversity of the solutions and find nondominated solutions.
