Sustainable supply chain management with pricing, greening and governmental tariffs determining strategies: A game-theoretic approach
مدیریت زنجیره تامین پایدار با قیمت گذاری، سبز کردن و تنظیم تعرفه های دولتی استراتژی: رویکرد نظری بازی-2017 Despite the considerable influence of the governmental regulations on the green supply chain, in the
most of the studies in the literature of green supply chain, almost the role of the government and inter
actions between the government and supply chains members’ decisions are disregarded. In this study, a
competitive mathematical model of government as the leader and two competitive green and non-green
supply chains as the followers is developed and for the first time in this paper, pricing policies, greening
strategies and governance tariffs determining in supply chains competition under government financial
intervals are discussed. In the presented framework, the government seeks social benefits and determines
subsidy and tax rates for green and non-green products respectively. The sale prices of products and the
green degree of the green product are supply chains’ decision variables. In centralized and decentralized
models, the optimal values of decision variables are gained and some important sensitivity analyses of
governance decisions are done. In the governmental decisions area, it is observed that the impact of rais
ing subsidy rate is significantly more than tax rate and it leads to increase in profits of government and
supply chains and sustainability of products. Also among the competition of supply chains, cooperating
between members makes more profit for them and leads to produce more eco-friendly products.

Competition, cooperation, and coopetition of green supply chains under regulations on energy saving levels
رقابت، همکاری و همکاری زنجیره تامین سبز تحت مقررات مربوط به میزان صرفه جویی در انرژی-2017 We develop price-energy-saving competition and cooperation models for two green supply
chains (GSCs) under government financial intervention. First, we study the best response
strategies of the chains for the given tariffs of a government. Second, we formulate 16
mathematical programming models regarding governments’ energy-saving, social welfare,
and revenue-seeking policies. We find that the government can orchestrate GSCs to fulfil
the financial, social, and environmental objectives by an appropriate tariff mechanism.
Moreover, cooperation in a GSC and between GSCs may facilitate the government’s sustain
able development policies. A comprehensive analysis on case study of brick production
GSCs reveals some important managerial insights.
