The Aircraft Assignment problem is the problem of assigning flights to aircraft in such a way that some operational constraints are satisfied, and possibly that some objective function is optimized. We propose an approach to aircraft assignment which captures all operational constraints, including minimum connection times, airport curfews, maintenance, and preassigned activities. It also allows...

This paper proposed a parallel automated assembly line system to produce multiple products having multiple autonomous guided vehicles (AGVs). Several assembly lines are configured to produce multiple products in which the technologies of machines are shared among the assembly lines when required. The transportation between the stations in an assembly line (intra assembly line) and among station...

We face the Routing and Wavelength Assignment problem considering as constraints the physical impairments that arise in all-optical networks. We propose a simple model for the physical layer considering both static and dynamic impairments. It is based on simulation of signal propagation in order to characterize each lightpath with a reliability parameter.

The general trend in the development of many video surveillance systems, traffic counting machines, security systems is the development of algorithms for tracking, which are very important in places with large numbers of people and vehicles, such as airports, city streets. In this paper we present an algorithm for multi-target tracking. Problem tracking is to build a trajectory of motion of tar...

 We consider a generalization of the classical quadratic assignment problem, where coordinates of locations are uncertain and only upper and lower bounds are known for each coordinate. We develop a mixed integer linear programming model as a robust counterpart of the proposed uncertain model. A key challenge is that, since the uncertain model involves nonlinear objective function of the ...
