The radio stripe (RS) system is a practical implementation of cell-free mMIMO, in which set multi-antenna access points (APs) serves at the same time-frequency resources user equipment (UE) network. APs are sequentially connected stripe, sharing fronthaul link to central processing unit. This work considers an uplink power optimization problem that aims enhance network spectral efficiency (SE) ...

In this paper, we investigate the bi-objective multiperiod one-dimensional cutting stock problem that seeks to minimize cost of production associated with total length cut objects (waste) and inventory costs related items. A mathematical model is presented heuristically solved by a column generation method. Computational tests were performed using Weighted Sum method, ε-Constraint method variat...

Vendor managed inventory is a continuous replenishment program that is designed to provide major cost saving benefits for both vendors and retailers. Previous research on this area mainly included single objective optimization models where the objective is to minimize the total supply chain costs or to maximize the total supply chain benefits. This paper presents a bi-objective mathematical mod...
