日本語
保全技術・トレードクレジット・インフレ・炭素税を統合した在庫モデルを構築し、MAPLEで数値解析した研究。保全と信用政策の併用がサプライチェーン総コストを大きく削減することを示す。感度分析で劣化率・インフレ・保全コスト・炭素税率の影響を整理し、持続可能性と財務政策の統合がコスト効率と環境責任を両立すると結論づける。
English
This study builds an integrated inventory model combining preservation technology, trade credit, inflation, and a carbon emission tax, solved numerically in MAPLE. Numerical examples show that jointly applying preservation and credit policies substantially lowers total supply chain costs. Sensitivity analysis clarifies how deterioration, inflation, preservation cost, and carbon tax rates shape inventory decisions, supporting cost efficiency alongside environmental responsibility.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
炭素税を在庫・調達コストに内部化する発想は、日本企業がSSBJやScope 3対応でサプライチェーン排出を管理する際の意思決定モデルとして参考になる。ただし制度・データは日本固有ではなく、実務適用には国内パラメータでの再検証が必要。
In the global GX context
The paper links carbon pricing directly to operational inventory and procurement decisions, a perspective relevant to Scope 3 management and internal carbon pricing under ISSB/CSRD-era disclosure. It offers a modeling template rather than jurisdiction-specific evidence, so global readers should treat it as a methodological contribution to integrating carbon costs into supply chain optimization.

📄 Abstract（原文）
This study develops an integrated inventory model that incorporates preservation technology, trade credit policy, inflation effects, and carbon emission tax considerations to optimize supply chain performance. Preservation technology is introduced to reduce product deterioration, thereby extending shelf life and improving consumption efficiency, while trade credit policies provide financial flexibility for retailers. The model reflects the growing influence of regulatory frameworks and technological advancements on inventory management, highlighting how these factors shape future commercial applications. By combining financial mechanisms with sustainability measures, the proposed framework offers a holistic approach to inventory control. The model is formulated mathematically and solved using MAPLE software, enabling precise evaluation of inventory costs under varying cycle lengths. Numerical examples validate the model’s applicability, demonstrating significant reductions in overall supply chain costs when preservation and credit policies are effectively integrated. Sensitivity analysis further explores the impact of key parameters-including deterioration rate, inflation, preservation cost, and carbon emission taxes-providing managerial insights into their role in inventory decisions. The findings confirm that integrating sustainability measures with financial and operational policies enhances cost efficiency, supports environmental responsibility, and strengthens supply chain resilience in modern business contexts.
