Multi-criteria optimization problems represent a crucial task for any designer of a public service system due to conflicting criteria, which have to be faced. Possible solution of this almost unsolvable situation can be seen in obtaining a series of

The public service system serves population spread over a geographical area from a given number of service centers. One of the possible approaches to the problem with two or more simultaneously applied contradicting objectives is determination of the

The usual approach to emergency system design consists in deploying a given number of service centers to minimize the disutility perceived by an average user, what is called “min-sum” or “system approach”. As a user in emergency tries to obta

The request of equal accessibility must be respected to some extent when dealing with problems of designing or rebuilding of emergency service systems. Not only the disutility of the average user but also the disutility of the worst situated user mus

Emergency service system, which satisfies randomly emerging demands of public for necessary treatment, is determined by deployment of limited number of service centers at positions from a given set of possible locations. The objective is to minimize

Vulnerability of a transportation network influences, importantly, the function of public service systems constituted on the network. To be able to study the importance of an individual network arc for proper functionality of the system, we suggested

When a service system is being designed, its resistance to randomly occurring detrimental events is often assessed. Several approaches can be used to include the influence of the events in the design process. This contribution deals with two such app

This paper deals with the emergency service system design using the weighted p-median problem formulation. In such systems, not only the disutility of an average user is minimized, but also the disutility of the worst situated users must be taken int

The paper deals with the min-max public service system design, where the generalized utility is considered. In contrast to the formulations presented in the literature, the generalized utility defined for a public service system assumes that the user
