This document discusses the aspects of network design.First a brief introduction of network design will be given.Then various types of assignment techniques will be discussed including the mathematical formulation and numerical illustration of the important ones.Then the concept of bilevel programming and few examples will be presented.Finally one such example, namely the network capacity expan...

A discomforting reality has materialized on the transportation scene: our existing air and ground infrastructures will not scale to meet our nation’s 21PP century demands and expectations for mobility, commerce, safety, and security. The consequence of inaction is diminished quality of life and economic opportunity in the 21PP century. Clearly, new thinking is required for transportation that c...

hub covering location problem, network design,   single machine scheduling, genetic algorithm,   shuffled frog leaping algorithm   hub location problems (hlp) are synthetic optimization problems that appears in telecommunication and transportation networks where nodes send and receive commodities (i.e., data transmissions, passengers transportation, express packages, postal deliveries, etc.) th...

This study focuses on how the term “urban resiliency” and other related terms are operationalized across spatial scales. The European Union United Nations established international goals, targets, specific measurable indicators with both Green Deal their 2030 Sustainable Development Goals (SDGs) to address climate change, overarching goals of becoming world’s first carbon neutral continent. Muc...

We give a model for the description of an urban transportation network and we consider the related optimization problem which consists in finding the desing of the network which has the best transportation performances. This will be done by introducing, for every admissible network, a suitable metric space with a distance that inserted into the Monge-Kantorovich cost functional provides the cri...

Current network modeling practices usually assess the network performance at specified time interval, i.e. every 5 or 10 years time horizon. Furthermore, they are usually based on partially predictable data, which are being generated through various stochastic procedures. In this research, a new quantitative based methodology which combines combinatorial optimization modeling and transportation...

The “EOIP; Every Thing Over IP“ networks are widely replacing today’s different pillar networks in to the single converged network for Telephony(Any type of Access i.e. Mobile or Fixed Line) and data. Definitely new services will be expected in the NGN / EOIP such as broadcast media transmission and video on demand. But one major issues are always from past so many years are associated with Int...

vehicular ad-hoc network (vanet) is an important component of intelligent transportation systems, in which vehicles are equipped with on-board computing and communication devices which enable vehicle-to-vehicle communication. consequently, with regard to larger communication due to the greater number of vehicles, stability of connectivity would be a challenging problem. clustering technique as ...

Performance, resiliency and programmability across the entire network are now fundamental business requirements for next generation cloud and enterprise data center networks. The need for agility and deployment at scale with regards to provisioning and network operations requires a new level of automation and integration with current data center infrastructure. The underlying design of the netw...
