Analysis and applications of replenishment problems under stepwise transportation costs and generalized wholesale prices
In this study, we analyze the replenishment decision of a buyer with the objective of maximizing total expected profits. The buyer faces stepwise freight costs in inbound transportation and a hybrid wholesale price schedule ...
Star p-hub center problem and star p-hub median problem with bounded path lengths
We consider two problems that arise in designing two-level star networks taking into account service quality considerations. Given a set of nodes with pairwise traffic demand and a central hub, we select p hubs and connect ...
Routing and scheduling decisions in the hierarchical hub location problem
Hubs are facilities that consolidate and disseminate flow in many-to-many distribution systems. The hub location problem considers decisions that include the locations of hubs in a network and also the allocations of the ...
Mechanistic force modeling for milling of unidirectional carbon fiber reinforced polymer laminates
Carbon fiber reinforced polymer (CFRP) usage in the aerospace industry has been steadily increasing due to its superior material properties such as high strength, low weight, high resistance to corrosion, and a low thermal ...
Minimum cost path problem for Plug-in Hybrid Electric Vehicles
(Elsevier Ltd, 2015)
We introduce a practically important and theoretically challenging problem: finding the minimum cost path for PHEVs in a road network with refueling and charging stations. We show that this problem is NP-complete and present ...
Aircraft recovery model with flight time controllability

Performance bounds on optimal fixed prices
We consider the problem of selling a fixed stock of items over a finite horizon when the buyers arrive following a Poisson process. We obtain a general lower bound on the performance of using a fixed price rather than ...
Static and dynamic VaR constrained portfolios with application to delegated portfolio management
We give a closed-form solution to the single-period portfolio selection problem with a Value-at-Risk (VaR) constraint in the presence of a set of risky assets with multivariate normally distributed returns and the risk-less ...
Full and conditional likelihood approaches for hazard change-point estimation with truncated and censored data
Hazard function plays an important role in reliability and survival analysis. In some real life applications, abrupt changes in the hazard function may be observed and it is of interest to detect the location and the ...
A hierarchical solution approach for a multicommodity distribution problem under a special cost structure
Motivated by the spare parts distribution system of a major automotive manufacturer in Turkey, we consider a multicommodity distribution problem from a central depot to a number of geographically dispersed demand points. ...
