flexibility is one of the most important indicators of a supply chain .a flexible supply chain in the face of market changes and customer needs, must be responsive to the changes and needs, to be able to attract customers in the a competitive marketplace. being aware of the flexibility of a supply chain helps managers to solve problems and overcome deficiencies and increase the competitive adva...

Wi-Fi technology is vulnerable to many attacks due to the lack of security, limitation of capability, power limitations, resource handling etc. Security is more and more important, and wireless monitoring and shielding are of prime importance for network security. In order to satisfy secure communication between all nodes, this paper proposes Advanced Technique for Monitoring and Shielding in W...

Distributed flexible AC- transmission system (D-FACTS) is a recently advanced FACTS device with high flexibility and smaller size. The DPFC can control power flow in transmission lines, regulate bus voltages and it can also enhance stability margin in power grids. Adaptive-neural network-based fuzzy inference system (ANFIS) combines features of artificial neural network and fuzzy controller. Th...

Continuing innovations in hardware technology and changing demands of a wide range of applications are the two main challenges faced by operating systems. To exploit the available hardware capabilities and to meet the requirements of applications, operating systems should be made tailorable. This can be achieved by opening up implementations and avoiding preemptive decisions during design and i...

in a large scale cyclic storage system ,as the number of rule parameters and/or number of operating period increase, general purpose gradient-based nlp solvers and/or genetic algorithms may loose their merits in finding optimally feasible solution to the problem. in these cases hybrid ga which decomposes the main problem into two manageable sub-problems with an iterative scheme between ga and l...
