Supply chains are complex systems that are difficult to be understood from the viewpoint of the single enterprise. This often leads to local optimizations that form an optimum for one company or a short section of a supply network. Such local optimizations endanger the competitiveness of the whole supply chain, as today not the single enterprise, but the production network (sometimes named Virt...

The rapid advancements of Information Communications Technology (ICT) are leading to extreme improvements in computing power and to the design and development of innovative products and new improved versions of the existing ones. As a result, ICT products become obsolete more quickly and in increased quantities resulting to ever-increasing waste of electrical and electronic equipment (e-waste)....

In this paper, a reverse supply chain network is investigated for a decision making. This decision is surrounded by complex flows of returned products, due to the increasing quantity, the type of returned products and the variety of recovery option products (reuse, recycling, and refurbishment). The most important problem in the reverse logistic network (RLN) is to orient returned products to t...

The blood supply chain as a part of healthcare systems play a substantial role in health improvement within societies, and blood supply for daily needs and especially in disasters is the challenges requiring more attention. This paper presents a fuzzy-stochastic mixed integer linear programming model to design blood supply chain network for disaster relief. To deal with the uncertainty in model...

in this paper, a comprehensive model is proposed to design a network for multi-period, multi-echelon, and multi-product inventory controlled the supply chain. various marketing strategies and guerrilla marketing approaches are considered in the design process under the static competition condition. the goal of the proposed model is to efficiently respond to the customers’ demands in the presenc...

This paper describes a dual delay-locked loop architecture which achieves low jitter, unlimited (modulo 2 ) phase shift, and large operating range. The architecture employs a core loop to generate coarsely spaced clocks, which are then used by a peripheral loop to generate the main system clock through phase interpolation. The design of an experimental prototype in a 0.8m CMOS technology is des...
