The line-planning problem seeks to determine the set of fixed routes (or lines) a transit operator should run, along with associated operation frequencies. We propose an optimization algorithm for the transit-line-planning problem based on bi-level p

The Benders decomposition algorithm often shows poor convergence. To improve the convergence of the Benders decomposition algorithm. Recently, it was proposed the use of feasibility cuts closest to a solution in the set defined by all feasibility cut

We consider optimization problems whose objective functions have uncertain coefficients. We assumed that, initially, the uncertain data are given as ranges, and probing of the true values of data is possible. The complete probing of all uncertain dat

This paper considers a variant of the bandwidth packing problem that determines paths for selected demands on a telecommunication network with given arc capacities to maximize the total revenue. Facilities on the arcs can be seen as M/M/1 queuing sys

Recently, there are attempts to utilize drones in the logistic application. We consider the case in which there are multiple drones with different characteristics, such as speed and battery capacity. The truck and drone collaborate the delivery to se
