| Abstract | Information sharing is useful for improving supply chain performance. Supply chain
members consider information as their competitive advantage. Vendor and retailer usually prefer to keep their own information. Hence, exchange of information on demand and
inventory level between them is not easily occurred. To deal with that, Vendor Managed Inventory (VMI) can be applied to tackle this problem. It has been observed that the use of VMI can help to reduce the total cost of the system and to improve the service level of the customer. However the development of VMI models for one vendor-one retailer and one vendor-multiple retailers supply system under stochastic demand has not been addressed
adequately in the existing literature.
In this research, we firstly develop a VMI model for one vendor-one retailer supply
network using periodic review (, ) inventory policy at retailer. Then a VMI model for the
same supply network is developed for the case when continuous review (, ) policy is
employed at retailer. Lastly, the first VMI model is extended to the supply network with one vendor and multiple retailers.
Due to the complexity of the developed models, genetic algorithm is employed to help obtain optimal solutions of the proposed models. For more details, genetic algorithm is used to find the optimal solution for the model of one vendor and one retailer system under stochastic demand using (, ) policy. For the other models using (, ) policy, simulation-optimization in combination with genetic algorithm is used to obtain optimal
solutions. The applicability of the developed models is illustrated through numerical
experiments. To examine the effects of the parameters in the model, sensitivity analysis are also conducted. |
