بهبود مدل تخصیص سفارش موجودی مدیریت ‌شده توسط تامین ‌کننده مبتنی بر فناوری بلاک چین

موجودی مدیریت ‌شده توسط تامین ‌کننده، یک توانمند‌ساز برای هماهنگی زنجیرۀ تامین در نظر گرفته می‌شود که در آن تامین‌کننده، موجودی مشتری را برای بهینه‌سازی زنجیرۀ تامین در اختیار می‌گیرد. با این‌ حال، اجرای موفقیت‌آمیز موجودی مدیریت‌شده توسط تامین‌کننده بر سطح اعتماد بالا، انتقال دقیق داده‌ها و تعامل کارآمد بین طرفین متمرکز است. این امر مستلزم به اشتراک ‌گذاری اطلاعات ازطریق ذی‌نفعان زنجیرۀ تامین است که به‌دلیل ترس از افشای این اطلاعات به رقبای خود و شفافیت داده‌ها، با مقاومت و چالش روبه‌رویند. این مقاله کاربرد فناوری بلاک چین و پتانسیل آن را برای اجرای موفق موجودی مدیریت‌شده توسط تامین‌کننده بررسی و یک چارچوب بلاک چین را برای هماهنگی تامین‌کنندگان و مشتریان پیشنهاد کرده است. این چارچوب شامل یک مدل ریاضی است که در نرم‌افزار متلب و الگوریتم متاهیورستیک، برای انجام چندین سفارش مشتری و تامین‌کننده به‌صورت متمرکز و غیرمتمرکز حل و در چارچوب بلاک چین تعبیه ‌شده است. این مقاله مطالعات موردی را برای ارزیابی عملکرد مدل پیشنهادی با مشخصه‌هایی نشان داده است که دربارۀ جزئیات چارچوب بلاک چین آن بحث می‌کند، همچنین سیستم‌های متمرکز و غیرمتمرکز را در قالب فناوری بلاک چین با یکدیگر مقایسه کرده است.

improved supplier-managed inventory order assignment platform enabled by blockchain technology

purpose: this study aims to propose a novel supplier-managed inventory model called block-smi, which is based on blockchain technology. block-smi is a customer-supplier collaboration architecture that utilizes blockchain technology to divide the main service integration problem into smaller sub-problems, each dealing with a smaller portion of the service/demand pool. block-smi aims to utilize the capabilities of blockchain technology to address the limitations of centralized approaches. centralized approaches often struggle with large-scale problems and struggle to derive near-optimal solutions efficiently. by leveraging blockchain technology, block-smi seeks to overcome such challenges and achieve more efficient and effective solutions. block-smi operates under the same hypothesis as the supply chain collaboration model and seeks to address the challenges of scaling by utilizing the decentralized and distributed nature of blockchain technology. in this paper, the application of blockchain technology and its potential for successful smi implementation are investigated. the framework includes a mathematical model for multiple supplier-customer order fulfillment which is embedded in the blockchain framework. some cases are studied to evaluate the performance of the proposed model compared to the literature, discussing the details of its blockchain framework.design/methodology/approach: first, a mathematical model has been formulated and developed. then, the mathematical optimization of nlp with an objective model has been developed. the proposed model has been solved by gams software and a genetic algorithm. the problem has been solved in a centralized network using a genetic algorithm to provide the total cost value of supply chain management.findings: the objective function of block-smi aims to minimize the overall inventory cost within the entire supply chain management. this cost includes the expenses borne by both the supplier and the customer. this objective function is evaluated by all solvers and customers, and it is used to guide the matching process of customer demand with suitable suppliers. the aim is to find an optimal solution that minimizes the overall inventory cost while meeting the customer’s requirements and ensuring that the supplier’s capabilities are utilized effectively. by minimizing the total inventory cost, block-smi aims to reduce the overall cost of supply chain management and improve efficiency. to evaluate the effectiveness of block-smi, several scenarios were conducted. these scenarios involved comparing the proposed method with a centralized mechanism that was commonly employed to handle similar types of problems. by comparing the performance and outcomes of block-smi with the centralized approach, this study aimed to assess the advantages and benefits of utilizing the decentralized blockchain-based solution. the characteristics of block-smi were further described and analyzed, and the results demonstrated that block-smi is an effective solution for supplier-managed inventory problems, especially for large-scale scenarios.
