Abstract
The increasing awareness for sustainability drives the establishment of circular supply chains. One approach to improve the triple bottom line involves the use of product-specific returnable transport items (RTI) rather than disposable packaging. However, little attention has yet been paid to decision support on joint optimisation of economic production and order lot sizes with simultaneous calculation of RTI fleet sizes considering different modes of ownership in a multilevel setting.
This research examines a three-echelon supply chain consisting of component supplier, manufacturer, and customer. The aim is to determine the joint economic production and order lot sizes with simultaneous determination of the required RTI fleet sizes for the supplier's and the manufacturer's products, taking into account different modes of RTI ownership (renting, purchasing, or a combination thereof) and return policies. Further, production, warehousing, and transportation capacity need to be respected. To achieve these objectives, a mathematical model is developed and solved. Numerical examples are provided to demonstrate the model's behaviour.
This work contributes to the existing body of literature by providing a decision support model for supply chain design to allow for optimized economic coordination of production lot sizes and order lot size in a three-echelon supply chain with two types of RTI, different ownership models and return policies within a deterministic context.
