Optimal Green Input Level for a Capital-Constrained Supply Chain Considering Disruption Risk

Under increasingly stringent environmental regulations, inadequate green input levels from manufacturers may lead to substandard emissions and production shutdown, which further results in the disruption risk of supply chain. This work investigates a chain (GSC) consisting one environmentally regulated manufacturer capital-constrained retailer who faces stochastic market demand. The needs make decisions on level, is related investment cost as well risk. has determine product order quantities financing decisions. We derive operational equilibriums for GSC system under three scenarios: no financing, trade credit (TCF), bank (BCF), recommend optimal financial selection via comparison modes. analytical numerical reveal that should improve level within capability enhance sustainable operation In addition, we find will choose since either BCF or TCF result higher profit than financing. Moreover, obtain threshold with can decide whether given corresponding parameters.
