📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではサプライチェーンのカーボンフットプリント削減が課題であり、本モデルは炭素税を考慮した在庫管理最適化の参考になる。ただし、炭素税率や制度の違いに留意が必要。
In the global GX context
As global carbon pricing expands, this inventory model incorporating carbon tax is relevant for supply chain decarbonization. However, it remains theoretical and requires adaptation to specific tax schemes.
👥 読者別の含意
🔬研究者:Operations research scholars can extend this model with stochastic demand or multi-echelon settings.
🏢実務担当者:Supply chain managers can explore preservation technology investments under carbon pricing to balance cost and emissions.
📄 Abstract（原文）
Objectives: The importance of preservation technology in this inventory model including imperfect quality items is reducing the carbon emission and wastages, maximizing the total profit and sustainable environment. Method: Introducing green concept into this model to reduce environmental pollution and protect the natural resources from the manmade disasters. Inventory models are generally developed for reducing the total cost. In this study, using preservation technology to extend validity period of the manufactured products avoid wastages. The differential equations and differentiation method is used for solving a numerical example. Findings: The derivations of the inventory level, optimum order quantity, ordering cost, purchasing cost, holding cost, shortage cost, lost sale cost, cyclic capital cost, transportation cost, preservation technology cost, sales revenue, and green technology investment profit are constructed. The developed model is illustrated with an example. The selling price of the products is $142.5/unit, the replenishment time per cycle is 1.5 month, the total profit of the manufacturing process using preservation technology is $2596, and the amount of carbon emission from the manufacturing industry is 38.9kg/month. Novelty: The integration of green concepts into inventory management through preservation technology intended to reduce losses and wastages while enhancing profitability. Keywords: Green Inventory system, Deteriorating items, Price based demand, Preservation technology and Carbon tax policy
