This paper uses the energy hub concept to meet the water, heat and electricity demand of a power plant in the Qeshm island in south of Iran. Given the power plant’s high potential for waste heat recovery and some scenarios were considered using the hub energy concept based on energy, exergy, environmental and economic analyzes in terms of meeting the demands of the hub and purchasing/selling en...
In this paper, a stochastic programming approach is applied to the airline network revenue management problem. The airline network with the arc capacitated single hub location problem based on complete–star p-hub network is considered. We try to maximize the profit of the transportation company by choosing the best hub locations and network topology, applying revenue management techniques to al...
the hub location decision is a long term investment and any changes in it take considerable time and money. in real situations, some parameters are uncertain hence, deterministic models cannot be more efficient. the ability of two-stage stochastic programming is to make a long-term decision by considering effects of it in short term decisions simultaneously. in the two-stage stochastic programm...
this paper proposes a new mathematical model for designing and planning postal parcels carriage and postal networks. the objective of postal network designing is to determine the location, size and connection between the postal stations in a city, province or country. in this paper, a kind of multiple locations-allocations hub problem with limited capacity in collecting, distributing and broadc...
Controllability of complex networks has been a hot topic in recent years. Real networks regarded as interdependent networks are always coupled together by multiple networks. The cascading process of interdependent networks including interdependent failure and overload failure will destroy the robustness of controllability for the whole network. Therefore, the optimization of the robustness of i...
This paper presents a new algorithm for dynamic routing of bandwidth guaranteed multicast tunnels with failure backup. The multicast routing problem arises in many contexts such as the routing of point-to-multipoint label switched paths in Multi-Protocol Label Switched (MPLS) Networks, and the provision of bandwidth guaranteed services under the “hose” model [4]. Failure backup implies that whe...
As embedded systems take more important roles at many places, it is more important for them to be able to show the evidences of system failures. Providing such evidences makes it easier to investigate the root causes of the failures and to prove the responsible parties. This paper proposes simultaneous logging and replaying of a system that enables recording evidences of system failures. The pr...
