gistics unit role on the road toward lean supply chain is key and one of the oldest and best-known routing problem of transportation due to the problems of logistics in many applications, it is still of interest to researchers. One of the most popular tools to achieve lean logistic is milk run system. This paper presents a mathematical model, the will milk run system for products from customers, and we try to get back into position. Because the model is NP-HARD, so we used the bat Algorithm to solve it.
