On column generation formulations for the RWA problem

چکیده
We present a review of column generation formulations for the Routing and Wavelength Assignment (rwa) problem with the objective of minimizing the blocking rate. Several improvements are proposed together with a comparison of the different formulations with respect to the quality of their continuous relaxation bounds and their computing solution ease.

Iterative Linear Programming Formulation for Routing and Wavelength Assignment in Optical Networks
In this paper, we consider the Routing and Wavelength Assignment (RWA) problem in Wavelength Division Multiplexing (WDM) networks. Firstly, we propose separate linear programming (LP) formulations for the lightpath routing and the wavelength assignment subproblems. Then, an iterative algorithm that integrates both formulations is also proposed for solving the complete RWA problem. The objective...
متن کاملP - 2535 Routing and Wavelength Assignment in Optical Networks
The problem of routing and wavelength assignment (RWA) is critically important for increasing the efficiency of wavelength-routed all-optical networks. Given the physical network structure and the required connections, the RWA problem is to select a suitable path and wavelength among the many possible choices for each connection so that no two paths sharing a link are assigned the same waveleng...
متن کاملAcceleration of Lagrangian Method for the Vehicle Routing Problem with Time Windows
The analytic center cutting plane method (ACCPM) is one of successful methods to solve nondifferentiable optimization problems. In this paper ACCPM is used for the first time in the vehicle routing problem with time windows (VRPTW) to accelerate lagrangian relaxation procedure for the problem. At first the basic cutting plane algorithm and its relationship with column generation method is clari...
متن کاملCockpit Crew Pairing Problem in Airline Scheduling: Shortest Path with Resources Constraints Approach
Increasing competition in the air transport market has intensified active airlines’ efforts to keep their market share by attaching due importance to cost management aimed at reduced final prices. Crew costs are second only to fuel costs on the cost list of airline companies. So, this paper attempts to investigate the cockpit crew pairing problem. The set partitioning problem has been used for ...
متن کاملA Genetic Algorithm for Choice-Based Network Revenue Management
In recent years, enriching traditional revenue management models by considering the customer choice behavior has been a main challenge for researchers. The terminology for the airline application is used as representative of the problem. A popular and an efficient model considering these behaviors is choice-based deterministic linear programming (CDLP). This model assumes that each customer bel...
