III this study, we consider the pricing of perishables in an inventory system where items have a fixi'd lifetime. Unit demands come from a Poisson Process with a price-dependent rate. The instances at which an item is ...

We consider the Vehicle Routing Problem with Backhauls, in which a eet of vehicles located at a central depot is to be used to serve a set of customers partitioned into two subsets of linehaul and backhaul customers. ...

In this study, we investigate the well-known shortest path problem on directed acyclic graphs under arc length uncertainties. We structure data uncertainty by taking the arc lengths as interval ranges. In order to ...

The end of the Cold War, sudden collapse of the Soviet Union in early 1990s, and the drastic changes they cause in the international system, induced a substantial transformation in the global scale and in the ambiguously ...

The Art Gallery Problem is the problem of determining the number of observers necessary to cover an art gallery such that every point is seen by at least one observer. This problem is well known and has a linear time ...

In the literature, scheduling models ignore the unavailability of the cutting tools. Tool management literature considers tool loading problem when tools change due to part mix. In practice, tools are changed more often ...

As being ready for war as soon as possible and with minimum casualties during the crises is the first mission for the troops, the Mobilization and Deployment Plan arises as one of the most important topic for Army. Because ...

In this study, an inventory model with one retailer and two suppliers is considered for a single item. Di erent from most of the models in inventory literature, we do not make the assumption that we receive all the ...

In this study, we analyze the network design problem arising in Wavelength Division Multiplexing (WDM) networks where tra c is static, wavelength interchanging is allowed and the location and number of the wavelength ...
