In today’s market, sales promotional schemes have spun out to be essential for promoting outfits. Nonetheless, due to the sudden ascent in sales, the subsequent demand uncertainty calls for the high flexibility in supply chains. The present work examines the barriers to flexibility in the Indian automobile supply chains under such an environment from a sustainability viewpoint, an indispensable element of the present-day supply chains. In view of the literature and the descriptive survey led, 20 barriers have been identified. Through the analytical investigation directed, a numerical index value for the sustainable supply chain flexibility barriers is developed via graph-theoretical and matrix approach. Findings, along with the sensitivity analysis, conducted establish that the barriers at the supply chain’s procurement function have the highest impact in inhibiting the sustainable supply chain flexibility, thus significantly affecting the firm performance during sales promotional schemes. The obtained barrier index can be utilised for assessing the performance of all the companies across the industry. The model proposed offers valuable discernments to practicing officials in focusing on the significant barriers. This study augments the existing literature by linking the supply chain flexibility, Sustainability, and Sales promotions and thus clubs the three independent research streams.

在当今的市场上，促销计划已成为推广服装必不可少的手段。尽管如此，由于销量的突然上升，随后的需求不确定性要求供应链具有高度的灵活性。目前的工作从可持续性的角度研究了在这种环境下印度汽车供应链灵活性的障碍，这是当今供应链不可或缺的要素。根据文献和所引导的描述性调查，已经确定了 20 个障碍。通过定向分析调查，通过图论和矩阵方法开发了可持续供应链灵活性障碍的数值指标值。调查结果，连同敏感性分析，研究表明，供应链采购职能的壁垒对抑制可持续供应链灵活性的影响最大，从而显着影响促销计划期间的公司绩效。获得的壁垒指数可用于评估整个行业的所有公司的业绩。所提出的模型为执业官员在关注重大障碍方面提供了宝贵的洞察力。本研究通过将供应链灵活性、可持续性和促销活动联系起来，扩充了现有文献，从而将三个独立的研究流结合起来。获得的壁垒指数可用于评估整个行业的所有公司的业绩。所提出的模型为执业官员在关注重大障碍方面提供了宝贵的洞察力。本研究通过将供应链灵活性、可持续性和促销活动联系起来，扩充了现有文献，从而将三个独立的研究流结合起来。获得的壁垒指数可用于评估整个行业的所有公司的业绩。所提出的模型为执业官员在关注重大障碍方面提供了宝贵的洞察力。本研究通过将供应链灵活性、可持续性和促销活动联系起来，扩充了现有文献，从而将三个独立的研究流结合起来。
