  Abstract:
  In this work we propose two new metaheuristic algorithms to cope with the Risk Constraint Cash-in-Transit Vehicle Routing Problem (RCTVRP for short) already introduced in the literature by (Talarico et al., 2012). The RCTVRP is a variant of the well-known capacitated vehicle routing problem that models the problem of routing vehicles in the cash-in-transit industry by introducing a risk constraint. In the RCTVRP the risk associated with a robbery, which is assumed to be proportional both to the amount of cash being carried and the time or the distance covered by the vehicle carrying the cash, is limited by a certain risk threshold. In this work we propose two metaheuristic algorithms named respectively m-ACO and p-ACO . Both the m-ACO and the p-ACO metaheuristics use the well known Ant Colony heuristic for the Traveling Salesman Problem introduced by (Dorigo, 1996). The risk constraint is relaxed and for this reason, the Ant Colony heuristic creates a single (TSP) tour. The best found giant TSP tour is subjected to a variant of the splitting procedure described in Prins (2004). The solution obtained after the splitting heuristics serve as input for the variable neighbourhood search block, which is composed of seven of the most common local search operators for vehicle routing problems, modified for the RCTVRP. The Ant Colony heuristic and the variable neighbourhood search block are embedded in two different global metaheuristic structures: a multistart and a destroy-and-repair (or perturbation) structure. Both the m-ACO and p-ACO metaheuristics, in their optimal setting, are used to solve all the instances contained in a specific set of RCTVRP instances named set O for which the optimal solutions are known (see (Talarico et al., 2012) for more details of the instances characteristics). The resulting methods are able to obtain solutions of excellent quality in very limited computing times.
