Recent years, there has been a growing attention on sustainability and corporate social responsibility (CSR). These issues are of high importance in pharmaceutical sector which directly impacts on health's society. In pharmaceutical supply chain (PSC), each member could enhance CSR in the supply chain from different aspects. This thesis investigates coordination of decisions in a pharmaceutical supply chain consisting of a single retailer, single distributor and single supplier. The investigated PSC faces stochastic demand for one kind of drug. Considering the real situation of pharmaceutical industry in IRAN, the distributor decides on the interval between two subsequent visit of the retailer. The retailer uses a periodic review order-up-to-level inventory system for replenishin items and decides on the order-up-to-level based on the visit interval of the distributor. On the other hand, the supplier could boost the market demand by investing in CSR issues. The decisions of members not only impact on their own performance, but also influence performance of the other members and CSR as well. In this study, the members' decisions are coordinated in order to improve the profits of the whole channel and individual profits of members by considering CSR indices. To this end, the investigated PSC is modeled under the decentralized and centralized decision-making structures, and then a collaborative decisions-making model is proposed as a new method for coordination of PSC. Different indicators are used to quantify the CSR issues such as investing in CSR, collecting unused and unwanted drugs and improving service level. Moreover, limited shelf life of the drug and the role of government in providing incentives to improve social responsibility are considered in this study. The results show that coordination of pharmaceutical supply chain members not improves the profits of the supply chain, but also improves the CSR.
