Enhancing Lagrangian dual optimization for linear programs by obviating nondifferentiability
(INFORMS, 2007)We consider non differentiable optimization problems that arise when solving Lagrangian duals of large-scale linear programs. Different from traditional subgradient-based approaches, we design two new methods that attempt ... -
Fitting the Ph-t/M-t/s/c Time-Dependent Departure Process for Use in Tandem Queueing Networks
(INFORMS, 2013)This paper considers time-dependent Ph-t/M-t/s/c queueing nodes and small tandem networks of such nodes. We examine characteristics of the departure processes from a multiserver queueing node; in particular, we focus on ... -
Integrated Airline Schedule Design and Fleet Assignment: Polyhedral Analysis and Benders' Decomposition Approach
(INFORMS, 2010)The main airline operations consist of schedule planning, fleet assignment, aircraft routing, and crew scheduling. To improve profitability, we present in this paper an integrated fleet assignment model with schedule ... -
The Ph-t/Ph-t/infinity (k) 100 (K) queueing system: Part II - the multiclass network
(INFORMS, 2004)We demonstrate a numerically exact method for evaluating the time-dependent mean, variance, and higher-order moments of the number of entities in the multiclass [Ph-t/Ph-t/infinity](K) queueing network system, as well as ... -
The Ph-t/Ph-t/infinity queueing system: Part I - the single node
(INFORMS, 2004)We develop a numerically exact method for evaluating the time-dependent mean, variance, and higher-order moments of the number of entities in a Ph-t/Ph-t/infinity queueing system. We also develop a numerically exact method ...
