The usefulness of these algorithms in the LNG carrier industry in the areas of risk assessment and maintenance modeling as a standalone or hybrid algorithm are identified. This is evidenced with illustrative case studies.展开更多

Similarly, risk arrangements are operated by reinsurance to insurance funding. But, how is the retakaful legal status in Islamic law and the differences between reinsurance. The objective of this study is to identify the status of the retakaful in Islamic law and identify the differences between reinsurance. The study to found that retakaful is prescribed and an alternative to reinsurance, as well as a method of financial protection against the various risks of the takaful industry in excess of the retention limit, which may occur at any time in accordance with the principles of Sharia. Also in this method of risk arrangements, It is found that there are very significant differences in risk between retakaful and conventional reinsurance.展开更多

The value of these clauses may be important and should be added to the total value of the concession. However, in these cases, traditional valuation techniques, like the NPV （net present value） of the project, are insufficient. An alternative methodology for the valuation of highway concession is one based on the real options approach. This methodology is generally built on the assumption of the evolution of traffic volume as a GBM （geometric Brownian motion）, which is the hypothesis analyzed in this paper. First, a description of the methodology used for the analysis of the existence of unit roots （i.e., the hypothesis of non-stationarity） is provided. The Dickey-Fuller approach has been used, which is the most common test for this kind of analysis. Then this methodology is applied to perform a statistical analysis of traffic series in Spanish toll highways. For this purpose, data on the AADT （annual average daily traffic） on a set of highways have been used. The period of analysis is around thirty years in most cases. The main outcome of the research is that the hypothesis that traffic volume follows a GBM process in Spanish toll highways cannot be rejected. This result is robust, and therefore it can be used as a starting point for the application of the real options theory to assess toll highway concessions.展开更多
