Application of multi-criteria optimisation in marina planning on the Montenegrin coast

Tomovic S., Sekulic G.

Polish Maritime Research

2014

nr 2

86--90

Development of nautical tourism in Montenegro, seen as a potentially profitable industry segment has started twenty years ago. The first steps taken in this direction were defining the legal framework, in particular: Law on Coastal Zone, Tourism Master Plan of Montenegro, Law on Yachts, followed by establishment of supporting organizations - Maritime Safety Department of Montenegro, Port Authorities and Border Police Department. Having invested efforts in adoption of planning documents and enactment of legislation relating to nautical tourism in recent period, Montenegro is seeking to impose itself as an important nautical destination. The first serious step towards achieving this goal was construction of a world-class marina Porto Montenegro in Tivat in 2010. The Special Purpose Spatial Plan for Coastal Zone provides for development of network of marinas to be constructed on the Montenegrin Coast. In the light of this, contribution of this paper is reflected in application of multi-criteria optimization in defining an optimum order of marina construction. The paper defines selection of criterion functions from the aspects of ecology, economy, security, specific aspect and aspect of suitability assessment for the location. The paper also presents the process of defining different criterion weights. The multi-criteria analysis determines a compromise solution for marina planning at Montenegrin Coast, which reconciles conflicting interests. The compromise solution is only a proposal, while a final decision remains with a decision maker.

Numerical determination of quadratic-optimal regulator for linear systems with constraints

Archives of Control Sciences

2004

Vol. 14, no. 3/4

231-246

The paper describes a way of determination of quadratic-optimal regulator for linear continuous and discrete systems with constraints. The method is based on direct numerical minimization of the quadratic criterion expressing the quality of control. Constant regulator matrix, independent on the starting state, is obtained as a result. Due to the constraints the optimal regulator however depends on initial state. Therefore, the problem formulation was modified by using an extended criterion of optimality that guarantees quality behavior for any initial state within a given set.
