The optimal resource allocation in stochastic activity networks via the electromagnetism approach

An optimal resource allocation approach to stochastic multimodal projects had been previously developed by applying a Dynamic Programming model [2] [3], which proved to be very demanding computationally. Approximations to the initial model had been also developed, still within DP framework [4]. Computing times were improved, but demonstrated the need for further developments. In this paper we report on the application of a recently developed technique for global optimization, the Electromagnetism Algorithm (EMA) [1], to this problem and demonstrate its superior performance to previously attempted approximations.
