A Sustainable Supply Chain Model with the Consideration of Logistics, Yard Management Systems, and Green Investments

Objectives: To analyze and justify the significance of yard management and green technology investments for both production and distribution processes in the supply chain along with effects of carbon taxes. Methods: A non-linear sustainable supply chain model considering carbon emissions during manufacturing, distribution, storage of inventory, idling during a delivery, idling and unnecessary wandering at a facility is formulated with an incorporation of yard management systems investments along with the effects of carbon taxes. Green technology investment is also incorporated to optimize total cost of systems. Lagrangian method is used to obtain the optimal solution of the problem. Findings: The proposed model has been solved with the prescribed method and it gives the total integrated supply chain model cost with yard management systems investment is $108,220.650 and the total integrated supply chain model cost without yard management systems investment is $112,520.340. This shows that the model with yard management systems performs better than the other one. Novelty: Yard management systems and green technology investment has been incorporated in a supply chain simultaneously, along with carbon taxes whereas earlier research has predominantly emphasized solely on green technology investments. 2020 Mathematics Subject Classification: 90B05, 90B06.
