An Optimization Model for Integrated Warehouse-Inventory-Transportation of a Multi-Echelon Supply Chain Anil Hakim Syofra, Tulus Tulus, Herman Mawengkang, Muhammad Zarlis Engineering Technology and Applied Science Research, 2025 Efficient supply chain management is crucial for cost reduction and service level optimization in today's competitive business landscape. This study presents a Mixed Integer Linear Programming (MILP) model to integrate warehouse, inventory, and transportation planning in a multi-echelon supply chain. The proposed model minimizes total operational costs while ensuring timely deliveries and maintaining optimal inventory levels. Key decision variables include warehouse capacities, inventory replenishment policies, and transportation routes, while constraints address demand fulfillment, transportation limitations, and storage capabilities. Computational experiments used realistic supply chain data to validate the model's effectiveness, demonstrating significant cost savings and efficiency improvements compared to conventional approaches. The results show that an integrated approach enhances supply chain resilience and sustainability, providing actionable insights for managers and decision-makers. This study contributes to supply chain optimization by offering a novel framework that bridges the gap between siloed decision-making and holistic data-driven strategies for enhanced operational performance.
Supply chain strategy during the COVID-19 terms: sentiment analysis and knowledge discovery through text mining Muhammad Khahfi Zuhanda, Yuan Anisa, Desniarti Desniarti, Muhammad Hafiz, Anil Hakim Syofra, et al. Indonesian Journal of Electrical Engineering and Computer Science, 2023 The coronavirus pandemic has affected not only health but also the economy. The use of big data in finding information can be used to gain profits that logistics companies can utilize to survive during the pandemic. This study conducted text-mining research on service consultant sites in the logistics sector. This study aims to present frequency diagrams, analyze sentiment using the National Research Council (NRC) lexicon, present bigrams, and seek knowledge about strategies to minimize shipping costs and maintain inventories of manufactured goods. The words "supply", "chain", and "COVID-19" are words that are used frequently throughout the article. The results of this study showed that the words that often appear from word excavation are the words "supply", "chain", "logistics", "kpis," and "inventory". Then emotion trust becomes an emotional word that often appears in articles. The words "Supply" and "pandemic" are the words that seem the most positive and negative words, respectively. The words "COVID-19", "safety stock", and "inventory management" are words that often appear together. The result of discovery knowledge is that logistics consultants offer emotions of trust and provide many insights on minimizing shipping costs and maintaining inventory during a pandemic.
