Many important problems in engineering management can be formulated as Resource Assignment Problem (RAP). The Workers (WAP) is considered a sub-class of RAP which aims to find an optimal assignment workers number tasks order optimize certain objectives. WAP NP-hard combinatorial optimization problem. Due its importance, several algorithms have been developed solve it. In this paper, it that man...

<p>Whale Optimization Algorithm (WOA) is a new meta-heuristic algorithm proposed by Australian scholar Mirjalili Seyedali in 2016 based on the feeding behavior of whales ocean. In response to disadvantages this algorithm, such as low solution accuracy, slow convergence speed and easy fall into local optimum, an improved Whale (IWOA) paper. We introduce chaotic mapping initialization keep ...

The main purpose of this paper was to use a combination of Energy-based design method and whale algorithm (WOA), hereinafter referred to as E-WOA, to optimize steel moment frames and improve the seismic performance. In E-WOA, by properly estimating the seismic input energy and determining the optimal mechanism for the structure, steel frames are designed based on the energy balance method; acco...
