摘要：The paper presents the idea of reference model of project prototyping problem for the projects that are at risk of failure.The hierarchical structure of declarative model connects two fields: functionalities of a typical service enterprise and management system of project execution in the enterprise.The functionalities as separate Constraints Satisfaction Problems (CSP) are described.CSP contains the sets of decision variables,their domains and constraints,which link these variables.The separated problems described as CSP,then in single main CSP are integrated.On the other hand,these problems can decompose into the subproblems concerning the functionalities of different fields.The open structure of model enables to solve the decision problems with different level of specificity.The decision problem can regard a query about the results of proposed decisions as well as the decisions guaranteeing the expected results.A declarative kind of proposed reference model in a natural way allows to implement its in constraint programming languages.The possibility of this approach illustrates an example.
