Özet:With the objectives including the reduction of the whole life costs, increasing construction and operation efficiencies and enhancing service quality, Public-Private Partnership (PPP) schemes have been used for healthcare projects across the world over the past two decades. These large-scale projects comprise a long-term partnership period between the public and private sector stakeholders, with a great deal of costs, risks and opportunities. Considering the large number of the parties involved and the inherent public interest, the vital importance of proper project planning and delivery in accordance with the project objectives becomes prominent. The major aim of this study was to construct a PPP healthcare project success model considering the interrelations between the success factors and integrate it with a decision support system that provides guidance to construction companies for performance assessment and improvement during the planning and execution phases of the PPP healthcare projects undertaken. At the outset, preliminary interviews were conducted with construction industry practitioners in conjunction with a literature survey to set forth the problem definition for the study. Subsequently, by means of a thorough review of the relevant literature, a conceptual framework was proposed addressing the success of PPP healthcare projects and semi-structured interviews were carried out with experts from the private sector. In light of the findings, the proposed framework was revised and used as a base for the development of the PPP healthcare project success model using the Analytic Network Process (ANP). A discussion session was held with the participation of five project executives for the construction of the model, through which, the relative importance of the elements and components, and the magnitude of the interrelationships inherent in the model were assessed based on the experts’ collective judgment. The ANP model was tested on two real cases during the session, which yielded favorable results. Finally, a web-based decision support system was developed, which performs project performance assessment based on the built-in success model, presents various reports on the assessment and assists in performance improvement. The system was tested and validated on five real projects, and as to the judgment of the experts, the overall performance of the system was regarded as satisfactory. As far as the potential contribution of the system’s functions to project processes were considered, guidance with the inherent network of success factors, proposal of performance improvement strategies and generation of alternative project scenarios were pointed out at the first place. The revealed results were discussed, together with the recommendations for the further improvement of the proposed system.
