Abstract: In this paper, an optimal model of multi-item single-level dynamic lot-sizing considering transportation decision in manufacturing system is studied. In the model, it is assumed that the freight cost is proportional to the number of containers, and the objective is to minimise total cost of the setup cost, holding cost and freight cost. Since the model is a mixed integer programming and it is a NP hard problem. An improved ant colony optimisation (ACO) algorithm is proposed. The algorithm is the trade-off between the solution quality and computational time. The computational result shows that the proposed algorithm is feasible and efficient based on solution quality and computation time compared with Lingo optimisation software. Computation examples show that the algorithm has advantage over software Lingo11.
