Abstract
The distribution of metallic coins is a challenging process that most Central Banks face. In this paper we propose a mathematical programming model to optimise the routing and inventory levels to satisfying the demand of banking places to minimise both traveling costs as well as CO2 emissions. We solve the bi-objective model via an epsilon-constraint approach and a heuristic dependent on the definition of the serviceable neighbourhood for the regional distribution centers. We show the advantages of implementing this model, discuss the trade-off of minimising cost versus emissions, as well as various sensitivity analysis for a planning period of one year for the Central Bank of Mexico.
