In the field of finance, the underwriting process is an essential step in evaluating every loan application. During this stage, the borrowers' creditworthiness and ability to repay the loan are assessed to ultimately decide whether to approve ...

An airline scheduler plans flight schedules with efficient resource utilization. However, unpredictable airline disruptions, such as temporary closures of an airports, cause schedule perturbations. Therefore, recovering disrupted ...

• We cover the multi-fleet aircraft recovery in cases of airline disruption.
• Q-...

Having a quick boot time has become a major issue in many consumer electronics to improve a user experience. Although instant on/off with persistent memory claims less than 1 second booting, the maturity of the technology is still in progress and the ...

• Pattern-based models for a two-dimensional two-stage guillotine cutting stock problem are analyzed and compared.

This study presents a theoretical and computational analysis of integer programs based on the concept of the patterns, the so-called pattern-based models, for a two-dimensional two-stage guillotine cutting stock problem. The full-...

This paper presents a distribution-robust approach to the single-period inventory control problem with multiple unreliable suppliers and stochastic demand. Using the mean and covariance that are assumed to be the only known data, the proposed approach ...

We consider a certain class of chance-constrained binary knapsack problem where each item has a normally distributed random weight that is independent of the other items. For this problem we propose an efficient pseudo-polynomial time algorithm based on ...

In this article, we propose a grid rotation method for glove sizing to accommodate a greater fraction of the population with a given number of sizes. The method is based on the optimization of two geometric variables, the rotation degree and the number ...

The bandwidth packing problem BWP concerns the selection of calls from a given set and the assignment of one path to each selected call. The ultimate aim of the BWP is to maximize profit while the routings of the selected calls observe the capacity ...

This paper presents a robust optimization approach to the network design problem under traffic demand uncertainty. We consider the specific case of the network design problem in which there are several alternatives in edge capacity installations and the ...

The integer multicommodity flow problem on a cycle (IMFC) is to find a feasible integral routing of given demands between @k pairs of nodes on a link-capacitated undirected cycle, which is known to be polynomially solvable. Along with integral polyhedra ...

The ring loading problem with integer demand splitting is that of routing @k traffic requirements on an undirected ring network. We present a compact polyhedral description of the set of feasible solutions to the problem, whose number of variables and ...

We consider some optimization problems arising in an efficient simulation method for the measurement of the tail of portfolio credit risk. When we apply an importance sampling (IS) technique, it is necessary to characterize the important regions. In ...

This paper deals with the Steiner tree packing problem. For a given undirected graph G = (V, E) with positive integer capacities and non-negative weights on its edges, and a list of node sets (nets), the problem is to find a connection of nets which ...

We consider the problem of designing a local network in a two level telecommunication network. Given one or two hub nodes, central offices (COs) and conduits, the problem is to find a set of unidirectional self healing rings (USHRs) which covers all COs ...

This paper considers the problem of designing a capacitated network with a tree configuration (CTP). For a given set of nodes with their capacities,k types of link facilities with various characteristics, and installation cost for connecting each pair ...
