This work presents sequential and parallel simulated annealing algorithm to solve the vehicle routing problem with time windows (VRPTW). The VRPTW is a combinatorial optimization problem in which the number of vehicles and the total distance travelled by the vehicles are to ...

The paper presents the problems of assessing the effect of changes in the properties of a photovoltaic matrix (photocells) induced by its faulty operation. The principles of determining the degree of changes in matrix properties in order to identify its parameters is propose...

Pulsed eddy current non-destructive evaluation is concerned in the paper. Impact of eddy-current probe’s configuration on response signals, especially on crack’s depth resolution from the signals is numerically investigated. Orientation of an exciting coil of the probe regarding surface of...

The paper presents an optimisation algorithm for the geometry of three-phase unscreened high-current busways with solid insulation. A genetic algorithm method and parallel computing were used for this purpose. Moreover, the paper discusses the methodology of defining an objective function&...

It has been presented a model that simulates of the ferrosilicon smelting process in submerged arc furnace. The model is a system of two closed isothermal reactors: the upper one with lower temperature T1, and the lower one with the higher temperature T2 among whic...
