Assignment Problem (AP), which is well known combinatorial problem, has been studied extensively in the course of many operational and technical researches. It has been shown to be NP-hard for three or more dimensions and a few non-deterministic methods have been proposed to solve it. This paper pays attention on new heuristic search method for the n-dimensional assignment problem, based on swarm intelligence and comparing results with those obtained by other scientists. It indicates possible direction of solutions of problems and presents a way of behaviour using ant algorithm for multidimensional optimization complex systems. Results of researches in the form of computational simulations outcomes are presented.
Nowadays, in dangerous reality, when various attacks' threats aimed at peacefully minded people are growing and to it more and more new illnesses and even epidemics are appearing rapidly and with greater strength than before, there is a pretty greater need for high security maintenance inside buildings, especially inside buildings of health service. This paper describes a method of hospital security assessment using sanitary zones division and logical trees and also presents innovative matrix model dedicated to this end.
