Comparison of Maintenance Strategy between Public Sector and Private Sector

This paper describes how privatization of a transport system can change the maintenance strategy of transport infrastructure. The management principle in the private sector is to maximize profit, while in the public sector it is to maximize the social surplus. The difference in the management principle leads to the contrasts in maintenance strategy. This paper aims to compare the maintenance strategy between the public and private sector. Maintenance strategies are defined as a solution of the stochastic control problem for each case of the public and private sector. The control problem describes the dynamic optimization with stochastic process of infrastructure quality. The model is applied to a pavement management problem. From the comparison between case studies, it is found that the management by the private sector has a stable strategy in terms of the critical level of infrastructure quality where the maintenance action should be done.
