Integrating Stochastic Demand, Green Investment and Hybrid Metaheuristic Search
The transition toward low-carbon supply chains requires inventory policies that jointly consider economic performance, service reliability and environmental impact. This study develops an integrated green inventory optimization framework for a two-echelon supply chain under stochastic demand and carbon cap-and-trade...
View ArticleResource-Aware Post-Quantum Hybrid Key Establishment with Forward-Secure Session Management
The transition to post-quantum cryptography (PQC) has become an immediate systems-engineering requirement because classical public-key mechanisms based on integer factorization and elliptic-curve discrete logarithms are vulnerable to sufficiently capable quantum computers. The harvest-now-decrypt-later threat furthe...
