In the era of Predictive, Preventive, and Personalized Medicine (PPPM), dispensing the drug to the right patient, the right dose, at the right time is crucial. The focus of this paper is to determine the optimal dimensions of Free-Fall-Flow-Rack AS/RS used in pharmacy, minimizing the service time. Since the number of rack segments is discrete, we formulate this problem as a nonlinear discrete optimization, where the objective function is provided by an analytical model of the retrieval travel-time. The results show that this method is well-suited to find the optimal rack dimensions with accuracy by taking into account the real nature of the rack face which is discrete and not continuous. |
