<em>Distribution and transportation are very vital for the company business beverages that must distribute its products to many areas of the consumer, for example is a bottled tea company.  A good distribution plan and an optimum route would decrease cost and time for distributing the products.  In a real case study for a bottled tea in Surakarta area, the fluctuating demand of consumers cannot be ensured and these mismatches by a salesman that should be based on the distribution plan and the realization of visit (RRK) resulted in the absence schedule. Therefore, it is required an optimum route to help the salesman in doing RRK or distribution without ignoring predetermined targets. There is a settlement solution will be more orderly preparation of these are using a Clark and Wright Saving Heuristic method. The method is able to assist the performance of salesmen and cost savings in the delivery of Surakarta area. In this paper, we have presented a real cases vehicle routing based on Clark-Wright algorithm to solve the open vehicle routing problem (OVRP) of bottled tea distribution in Surakarta District. We have modified the Clark Wright algorithm with three procedures composed of Clark and Wright formula. The methods of swap, 2 OPT and 3-OPT were used to improve our best solution in shortest route and the cheapest cost of distribution.</em>

Purpose: We consider a real case study of a vehicle routing problem with a heterogeneous fleet and time windows (HFVRPTW) for a franchise company bottling Coca-Cola products in Colombia. This study aims to determine the routes to be performed to fulfill the demand of the customers by using a heterogeneous fleet and considering soft time windows. The objective is to minimize the distance traveled by the performed routes.Design/methodology/approach: We propose a two-phase heuristic algorithm. In the proposed approach, after an initial phase (first phase), a granular tabu search is applied during the improvement phase (second phase). Two additional procedures are considered to help that the algorithm could escape from local optimum, given that during a given number of iterations there has been no improvement.Findings: Computational experiments on real instances show that the proposed algorithm is able to obtain high-quality solutions within a short computing time compared to the results found by the software that the company currently uses to plan the daily routes.Originality/value: We propose a novel metaheuristic algorithm for solving a real routing problem by considering heterogeneous fleet and time windows. The efficiency of the proposed approach has been tested on real instances, and the computational experiments shown its applicability and performance for solving NP-Hard Problems related with routing problems with similar characteristics. The proposed algorithm was able to improve some of the current solutions applied by the company by reducing the route length and the number of vehicles.
