This paper discusses recent changes in the way public services are delivered A marked increase in the cooperation between the public and private sector in the realization of complex projects, mostly concerning development of infrastructure, is the main characteristic of present-day developing economies. The creation of new, innovative agreements is driven by the limitation of public funds and an ever-growing demand for an increase in the quality of public services. Looking upon the western economies experience alternatives to the traditional public sector procurement are identified in the public/private partnership. The public/private partnership can be seen as one component in the rearrangement of the public sector with a management culture that focuses on the citizen or customer. Also included in this are accountability for results, investigation of a wide variety of alternative service delivery mechanisms, and competition between public and private bodies for contracts to deliver services consistent with cost recovery and the achievement of value for money. The partnership can be realized through an array of models and in this paper priority is given to the DBFO (design-build-finance-operate) model, due to its importance in implementation. The DBFO model is considered to be a synonym for the public/private partnership, as it is the most suitable for complex projects and gains the most benefits.

In the early termination of public-private partnership (PPP) projects, compensation is considered a core issue that greatly affects the interests of the government and the private sector. To address the early termination that is frequently caused by government default or voluntary buyback, this paper proposes an ex-ante compensation mechanism using the cumulative probability that a given demand could be realized to determine early termination compensation under demand uncertainty. By splitting the compensation into two parts, the base compensation could be the minimum compensation for the private sector, while the additional compensation is considered a reasonable allocation of future booming demand. The predetermined compensation criterion ensures a smooth transfer of the early terminated project, which not only benefits the government from being overcharged, but also enables the private sector to gain a reasonable compensation for the remaining concession period.

The decision making for risk allocation problems in public–private partnership (PPP) projects is a vital process that directly affects the timeliness, cost, and quality of the project. Fair risk allocation is a vital factor to achieve success in the implementation of these projects. It is essential for private and public sectors to apply efficient risk allocation approaches to experience a more effective process of agreement arbitration and to reduce the appearance of dispute during the concession period. The aim of this study is to develop an optimization approach to enhance risk allocation process in PPP projects. The shared risks in projects are identified through comprehensive literature review and questionnaire survey obtained from Malaysian professionals involved in PPP projects. Objective functions are then developed to minimize the total time and cost of the project and maximize the quality while satisfying risk threshold constraints. The combinatorial nature of the risk allocation problem describes a multi-objective situation that can be simulated as a knapsack problem (KP). The formulation of the KP is described and solved applying genetic algorithm (GA). Due to the flexibility of GA, the results are Pareto Optimal solutions that describe the combinations of risk percentages for shared risks in PPP projects.

Purpose The purpose of this paper is to investigate the critical decision factors of public–private partnership (PPP) concession which is complex due to a number of uncertain and random variables. To identify critical factors contributing to determination of concession period, this study reviews the published literature. It also identifies countries contributing most in PPP research. As a whole, it provides a mutually beneficial scenario by formulating a decision-making matrix. Design/methodology/approach This paper reviews the literature published during the period 2005-2015. A two-staged methodology is followed on retrieved scholarly papers: first, countries contributing to PPP are identified along with authors and affiliated institutions. Second, using frequency analysis of shortlisted critical factors, yearly appearance and stakeholders affected, a decision matrix is formulated. Findings The most contributing country toward PPP research is China, followed by the USA both in terms of country- and author-based contribution. In total, 63 factors are identified that affect PPP concession out of which, 8 per cent are highly critical and 21 per cent are marginally critical for decision-making. Practical implications Critical factors of PPP concession period will be identified with the help of decision-making matrix. This will help in adequate resource allocation for handling critical factors ensuring project success. Researchers may also understand the research trends in the past decade to usher ways for future improvements. Originality/value This paper reports findings of an original and innovative study, which identifies critical success factors of PPP concession period and synthesizes them into a decision-making matrix. Many of the previous studies have identified and ranked the critical factors but such a synthesis has not been reported.

In the past two decades, public private partnership (PPP) has been one of the prevailing ways for the development of infrastructure in Malaysia. However, it involves many risks and uncertainties due to large investments and a long concession period. It is very important to recognize and find out ways to cope with the critical risks that are related to the investments made in PPP projects by foreign investors. The aim of this article is to risk ranking associated with PPP projects using a risk matrix. The papers carries out literature review, consultation and questionnaire survey (among a panel of experts) to identify common risks in PPP projects. The risks identified from the literature were classified according to the type of risk. Finally, the results show that third party tort liability, interest rate volatility, construction cost overruns, and changes in law are critical risks.
