This paper investigates an integrated supplier selection and inventory control problems in supply chain management by developing a mathematical model for a multi-echelon system. In particular, a buyer firm that consists of one warehouse and N identical retailers procures a type of product from a...

As quasi 2D semiconductors, bismuth oxychalcogenides (Bi 2 O 2 X, X = S, Se, Te) have recently attracted increasing attention due to their unique structure, exceptional air stability, and high electron mobility, which make them very promising candidates for the development of high-performance...

This research aims to minimize the bi-criteria of makespan and maximum tardiness on a set of identical batch-processing machines arranged in parallel. Each machine can process multiple jobs simultaneously as long as the machine capacity is not exceeded. Each job is defined by its processing...
