Coordination of social responsibility and order quantity in a two-echelon supply chain: A collaborative decision-making perspective
هماهنگی مسئولیت اجتماعی و میزان سفارش در یک زنجیره تامین دو مرحله ای: یک دیدگاه تصمیم گیری مشترک-2017 Regarding globalization growing trend and sustainability concerns, the need for paying attention to the issues of
corporate social responsibility (CSR) not only applies to individual firms, but also extends to the whole supply
chain (SC) networks. Assisting CSR issues in one individual firm will thoroughly influence other supply chain
members. In this paper, a supplier-retailer SC is considered in a newsvendor setting. It is possible for the
supplier to invest in CSR activities which could improve the popularity of products and, subsequently, market
demand. Firstly, both members decisions under decentralized and centralized decision-making models are
investigated; afterwards, a novel collaborative model is proposed to determine optimal order quantity and CSR
investment, thus maximizing the whole SC profits and also motivating members to participate. Finally, the
results of decentralized, centralized, and collaborative models are compared and some managerial insights are
provided. Numerical experiments indicate that, under some circumstances, alongside the increment of SC
profits, more CSR investment and better CSR performance level will be achieved through the collaborative
model than other decision-making structures.

Economic and social collaborative decision-making on visit interval and service level in a two-echelon pharmaceutical supply chain
تصمیم گیری اقتصادی اجتماعی و همکاری اجتماعی در بازه زمانی بازدید و سطح خدمات در یک زنجیره تامین دارویی دو نفره-2017 In this paper, simultaneous coordination of visit interval and service level in a two-echelon pharma
ceutical supply chain (PSC) with stochastic demand is studied. In the investigated model, a single
pharmaceutical supplier (pharma-supplier) visits a single pharma-retailer at constant intervals and
subsequently delivers the order after a deterministic lead-time. The pharma-retailer employs a periodic
review inventory system and decides on the PSC service level, which impacts on the pharma-suppliers
profitability. On the other hand, the pharma-supplier has full authority over the visit interval which
determines order delivery frequency and consequently impacts on the pharma-retailers inventory costs.
Firstly, both members decisions under decentralized and centralized decision-making structures are
investigated, and afterward collaboration models are proposed in two different scenarios: (1) economic
collaborative decision-making and (2) social collaborative decision-making. Finally, a set of numerical
examples is carried out to compare the performance of different decision-making structures. The results
indicate that collaborative decision-making on visit interval and service level could be of great benefit,
both socially and economically.
