The optimal network design for knowledge sharing in a supply chain for horizontal integration

Integrating is one of the steps that creates cooperation among supply chain members and improves the performance of the chain of custody to reduce the impact of whipping. Knowledge sharing among the members of a chain level is one of the strategic level partnerships that strengthen the integration in the chain. For this purpose, the most important step is to find the best knowledge sharing network among the members of the chain, so that the minimum cost can be incurred for the collaboration of members and the exchange of knowledge among them will be maximized. This paper presents a new mixed integer programming model on the basis of which a certain problem was formulated and implemented for the level of producers in a dairy supply chain. By sensitivity analysis, the parameters affecting the knowledge sharing network were identified. One of these important parameters is the distance between companies. Another one is the ability to exchange knowledge of companies that affects the duration of the sharing process. The findings of the study provide managers with the necessary insight regarding the resource constraints, market conditions, and the objectives of the companies. This helps them make the best decisions regarding the integration of the supply chain through knowledge sharing.
