This paper develops an economic production quantity (EPQ) model for a single-manufacturer multi-retailer (SMMR) production and reworking system with green and environmental sensitive customer demand. The minimum cost of the manufacturer has obtained under carbon emissions (CE) policies and discrete ordering cost reduction. The model is used to optimize the total number of shipments, greening investment level, environmental measure, and lot size for productions and rework. This research work determines that the manufacturer's and retailer's profits will be increased after considering the environmental and green dependent demand of customers. Further, the development of green and environmental demand is proposed to minimize the CE and maximize the demand for the customers. In the existing literature, no discrete investment is developed for reducing the cost of ordering for the retailer/buyer. However, in this paper, we have introduced it. We provide numerical examples to explain the models and determine the significance of model parameters.

本文针对具有绿色和环境敏感客户需求的单一制造商多零售商 (SMMR) 生产和返工系统开发了经济生产数量 (EPQ) 模型。制造商在碳排放（CE）政策和离散订购成本降低下获得的最低成本。该模型用于优化出货总量、绿化投资水平、环境措施以及生产和返工的批量大小。这项研究工作确定，在考虑客户的环境和绿色依赖需求后，制造商和零售商的利润将会增加。此外，提出了绿色和环境需求的发展，以最小化 CE 并最大化客户的需求。在现有文献中，没有为降低零售商/买家的订购成本而开发离散投资。但是，在本文中，我们介绍了它。我们提供数值示例来解释模型并确定模型参数的重要性。
