MARKOV TYPE DECISION SUPPORTING SYSTEM

Abstract

A decision model for pavement management has been developed herein based on linear programming formulation. Markov transition probability matrices are introducecl to model the deterioration process of the road sections. To eyery type of road surfaces and class of traffic amount belongs a certain Markov matrix. The presented model and methodology is used to determine the optimal rehabilitation and maintenance policy in network level. Depending on the objective function two types of problems could be solved by the model: the necessary funds calculation and the optimal budget allocation for the entire network. We have developed the computer program on microcomputer and it has been used by the Ministry of Transport who is responsible for the 30000 km road network of Hungary.
