"Logic and probabilistic evaluation and analysis of risk"

We have developed new approaches and methods in modeling and analysis of risk in banking and financial sphere. Our methods based on the logical probabilistic risk evaluation models and implemented in software package (SP) LP-evaluation of risk. The distinguishing features of our methods and SP could be summarized as follows:

1. Novelty and advantages of SP "LP-evaluation of risk"

2.Comparison of different methods accuracy in credits classification

LP-model with GIE Var.1




LP-model without GIE Var.2




LP-model with GIE after structural
identification - Var. 3




3. Functions of SP

4. Users of SP "LP-evaluation of risk":

Banks of all countries in the world; with the help of SP every bank does the training of its risk LP-models using statistical data on its bank.

5. Developers:

We have large experience in developing and practical application of those kind algorithms. It is the united team of qualified specialist in the area of risk-management with the western experience and has possibility to make development on Windows and Java platforms. With the low labor cost and highly productive and qualified programmers, we can keep up the low prices regarding to competitors. Within several months we could develop the commercial version our SP "LP-evaluation of risk". We offer also the maintenance and further development of SP "LP-evaluation of risk", according to the client needs and demands, the issue of ad-hoc version, reports, etc.

6. Realization:

SP "LP-evaluation of risk" will consist of modules, developed on C ++. Software core of SP "LP-evaluation of risk" will consist of about 3000 operators. At present time there are modules of various functionality in DELPHI-4, C++ and JAVA. Fragments of possible realization SP can be found in demo-version.

7.Our Suggestion

We suggest to make joint project and develop software tools, based on our LP-models and know-how for risk evaluation in banking and financial sphere. To estimate the possible cost of that job we need addition information from your side:

8.Prospect of cooperation

To adapt the SP "LP-evaluation of risk" for evaluation and analysis risk:
