Generalized bathtub model of network trip flows

New Algorithms for Generalized Network Flows

This paper is concerned with generalized network ow problems In a generalized network each edge e u v has a positive ow multiplier ae associated with it The interpretation is that if a ow of xe enters the edge at node u then a ow of aexe exits the edge at v The uncapacitated generalized transshipment problem UGT is de ned on a gen eralized network where demands and supplies real numbers are ass...

A Bathtub Model of Traffic Congestion

In the standard economic models of traffic congestion, traffic flow does not fall under heavily congested conditions. But this is counter to experience, especially in the downtown areas of most major cities during rush hour. This paper presents a bathtub model of traffic congestion. The height of water in the bathtub corresponds to traffic density, velocity is negatively related to density, and...

A New Bathtub Shaped Failure Rate Model

In this paper, we introduce a new Bathtub shaped failure rate model named as x-Exponantial Model and present a comparative study with Generalized Lindley, Generalized Gamma and Exponentiated Weibull distributions.

X-exponential Bathtub Failure Rate Model

The properties of x-Exponantial Bathtub shaped failure rate model are discussed. Estimation process and failure rate behavior is explained.
