Title:

Optimal Paths in Dynamic Networks with Dependent Random Link Travel Times

Accession Number:

01340215

Record Type:

Component

Abstract:

The authors find paths with minimum expected disutility in a stochastic time-dependent network where all link travel times at all times are jointly distributed random variables. A comparison is made with similar problems that do not consider the stochastic dependencies, through theoretical results in small networks and computational results in large networks. The impact of stochastic dependencies on optimal path generation is shown to be related to the level of correlation and risk attitudes.
