A new approach is developed for the automatic (computer based) exploration and analysis of hydrological data, particularly focused on the identification of shifting relationships among hydrological variables. The methodology developed is applicable to many hydrological problems, such as...

We consider the NP-hard Multiple Depot Vehicle Scheduling Problem, in which a given set of time-tabled trips have to be assigned to vehicles stationed at different depots, so as to minimize the number of vehicles used and the overall operational cost. The problem arises in the management of...

The problem of cyclic scheduling of two hoists is defined as follows. There are N + 1 workstations, S₀, S₁, ..., S_N, and two identical hoists that move jobs between stations. Jobs are identical and each job has to visit all stations in the order that stations are numbered. It is assumed that the...
