Deterministické, heuristické a hybridné modely pre optimalizáciu distribučných sústav pre rozvod vody

Abstract eng:
A water distribution network is an important component of an urban infrastructure (or an agricultural landscape as an irrigation project) and requires significant investment. Therefore, researchers are constantly searching for new ways to create more economical and efficient design methods Various optimization techniques have been applied to the optimal design of water distribution networks. Problems with adapting mathematical programming methods to looped network problems have restricted the use of LP to branched layouts only. Although there are some examples of efforts to use models for the design of looped networks, mainly by using mathematical programming (non-linear programming, dynamic programming), such a problem is still considered to be difficult to solve, particularly if one decides to tackle complex, real life networks. The researchers have focused on stochastic or so-called heuristic optimization methods from the early 1990s. Nevertheless, it must still be pointed out that there is no proof that any of the solutions given by the heuristic algorithms referred to above provide global optimality relative to the optimal design of water distribution networks. In the proposed hybrid method, the complementary usage of deterministic and heuristic methods will ensure a new level for the quality of the outputs from the point of view of effectiveness and closeness to global optimum.
