Authors: Miguel Aguilar Zaragoza, Idalia Flores de la Mota
Abstract
Trying to maintain a service level in many operations can result very expensive, especially if there are severe penalties due to a low level related with the service level objective. In such cases, we seek to achieve a goal even at the cost of significant loss in the operation efficiency. In particular, bank companies at their branches undertake transactions related to cash money as main service, so, not having available cash becomes a critical issue, which slightest consequence is the bank company prestige deterioration, and not only affectations for a specific branch. This paper has the purpose of establish an approach for cash transactions demand at bank branches, with perspectives that best fit, which helps to control the risk of stocking out of cash, setting up some parameters, e. g. branches? safety stock of cash, and projecting horizons of cash balances, given certain scenarios. The model we present is developed with frequentist and Bayesian perspectives, the last one is a ?recent? develop that covers in a more efficient way, the Markov Chain Monte Carlo (MCMC) simulations. So, by means a real evaluation, it will be estimated the accuracy level that can be got approaching the cash demand with each of these, in particular with the best.
