Title: Problem Characterization of Unique Shortest Path Routing

Abstract:

To demonstrate the necessity and importance of solving the unique shortest path routing problem based on and tailored to a complete formulation, the problem characteristics with respect to objective functions, constraints, and solution qualities are studied, including the impacts of objective functions and lower & upper bounds of the problem. To illustrate the advantage of developing an exact solution approach to the problem, the resulting routing performance from the unique shortest path routing problem are compared with those from using two default methods as well as those from two relaxed problems. It is shown that by solving the problem based on a complete formulation and an exact algorithm, the resulting routing performance is notably improved, relative to that from using the two default methods, and is competitively close to the lower bounds.
