1 Pricing and greening decisions of competitive forward and reverse supply chains under government financial intervention: Iranian motorcycle industry case study
تصمیمات قیمت گذاری و سبز سازی زنجیره های عرضه رقابتی به جلو و معکوس تحت مداخله مالی دولت: مطالعه موردی صنعت موتورسیکلت ایران-2021
The necessity for sustainable development and to support eco-friendly products have manifold the government responsibility in directing green activities. This paper theoretically studies the moderating role of government in pricing and greening decisions of chain-to-chain competition in developing substitutable green products under government involvement in supporting green product distribution and/or recycling through assigning monetary tariffs to customers and practically adjusts a real-world case study of the Iranian motorcycle industry issues. We examine two competitive supply chains (SCs) consisting of one retailer and one manufacturer under two-way logistics, i.e. forward SC that distributes green products and backward SC that collects pollutant products from the market. In addition to maximizing the profit of each SC member and minimizing government expenditure, reductions in environmental pollution are also examined. This study examines the impact of government policies in equilibrium strategies through six scenarios, based on different government elective policies, and using Nash or Stackelberg game structures. A computational analysis of the case study reveals that under more constrained budget situations, the government should resist the urge to reduce recycling tariffs, compared with distribution tariffs. The greatest reduction in environmental pollution is achievable through: government financial support only for recycling with the lowest investment rejection behavior, following a Nash game, reducing greening costs, increasing tendencies towards environmental protection, and increasing the rate of recyclable products. The greatest profit for firms is obtainable through: government financial support of distribution and recycling logistics with the lowest tendency towards environmental protection, following a Nash game, reducing greening costs, reducing the investment rejection behavior of the government, and increasing the rate of recyclable products.

2 Reviewing the use of the theory of inventive problem solving (TRIZ) in green supply chain problems
بررسی استفاده از تئوری حل مسئله اختراع (TRIZ) در مشکلات زنجیره تامین سبز-2017
The purpose of the paper is to review the practice of the theory of inventive problem solving (TRIZ) in Green Supply Chain (GSC) problems and to identify new research challenges focusing on the question: “To what extent is it necessary to evolve TRIZ tools, methods and theoretical grounding for addressing GSC inventive problems?” First, a review of the past contributions of TRIZ based methods to GSC problem resolution is presented. As the result of the papers review did not provide a comprehensive under standing of the limitations and areas of potential application of TRIZ in GSC, three experiments were conducted to complete the literature review, in order to provide a more comprehensive answer to the posed question and identify research challenges. The experiments addressing GSC problems were also conducted to explore to what extent the more mature meta-methods of classical TRIZ, namely ARIZ 85 A, C and the related sub-methods, can be used as in GSM problems. The examples were chosen to explore types of GSC problems that were not yet addressed with TRIZ. The experiment results highlight limi tations on the use of the TRIZ in GSC inventive problems, which were not mentioned in the GSC liter ature. Moreover it highlights the limitation of using the more mature meta-methods of TRIZ (ARIZ 85A and ARIZ 85C) when the conflict to overcome contains more than two evaluation parameters and one action parameter. Finally, research challenges to overcome the limitations and to improve the use of TRIZ in GSC inventive problems are stated. Among them, methods for quickly establishing the existence of classical TRIZ contradictions or for informing the problem solver when no TRIZ contradictions are present in a given inventive problem in GSC should be proposed. Such methods would permit determining whether ARIZ 85C could be used and avoid a long and fruitless search for a system of contradictions. Find alternatives to the algorithms proposed in the past to be able to establish the generalized contradictions of inventive problems. Make evolve meta-methods ARIZ 85C or substitute it with methods which can address the inventive problems that cannot be treated by ARIZ 85C.
