Abstract

An evaluation model generation device is provided to generate an evaluation model which evaluates the function or non-function of an IT system based on a system model including a process model which describes processing between processes on the IT system, a server model which describes a physical system configuration of the IT system, and allocations which represent correspondence relations between the elements in the process model and those in the server model. The evaluation model generation device includes: path enumeration means 110 which extracts a process path between processes in the process model, and a server path corresponding to the process path and located on the server model; allocation estimation means 120 which estimates the allocation based on the process path and the server path; and model conversion means 130 which converts the system model into the evaluation model using the process paths, the server paths, and the estimated allocations.

An evaluation model generation device for generating an evaluation model which evaluates the function or non-function of an IT system based on a system model including a process model which describes processing between processes on the IT system, a server model which describes a physical system configuration of the IT system, and allocations which represent correspondence relations between the elements in the process model and those in the server model, the evaluation model generation device comprising:

a path enumeration unit which extracts a process path between processes in the process model, and a server path corresponding to the process path and located on the server model;

an allocation estimation unit which estimates the allocation based on the process path and the server path; and

a model conversion unit which converts the system model into the evaluation model using the process paths, the server paths, and the estimated allocations.

2. The evaluation model generation device according to claim 1, wherein the path enumeration unit in search of a server path searches preferentially for the link having the same attribute as that of the link on the previously extracted server paths based on the attributes attached to links between the elements in the server model.

3. The evaluation model generation device according to claim 2, wherein the path enumeration unit generates a post-allocation replacement path by converting those elements included in the allocations in the process path into elements in the server model based on the allocations, and extracts as the server path on the server model the shortest path between the elements making up the post-allocation replacement path.

4. The evaluation model generation device according to claim 2, wherein when an element in a process path does not exist in an allocation, the allocation estimation unit compares the process path with the server path corresponding to the process path so as to estimate the element in the server path to which the element in the process path corresponds, and provides the allocation additionally with information indicative of the correspondence relations between the element in the process path and the estimated element in the server path.

5. The evaluation model generation device according to claim 2, wherein the model conversion unit sets an attribute value corresponding to additional information set to an element in the process model or server model, to the element in the evaluation model corresponding to the element.

6. The evaluation model generation device according to claim 1, wherein the path enumeration unit generates a post-allocation replacement path by converting those elements included in the allocations in the process path into elements in the server model based on the allocations, and extracts as the server path on the server model the shortest path between the elements making up the post-allocation replacement path.

7. The evaluation model generation device according to claim 6, wherein when an element in a process path does not exist in an allocation, the allocation estimation unit compares the process path with the server path corresponding to the process path so as to estimate the element in the server path to which the element in the process path corresponds, and provides the allocation additionally with information indicative of the correspondence relations between the element in the process path and the estimated element in the server path.

8. The evaluation model generation device according to claim 6, wherein the model conversion unit sets an attribute value corresponding to additional information set to an element in the process model or server model, to the element in the evaluation model corresponding to the element.

10. The evaluation model generation device according to claim 9, wherein the model conversion unit sets an attribute value corresponding to additional information set to an element in the process model or server model, to the element in the evaluation model corresponding to the element.

11. The evaluation model generation device according to claim 1, wherein the model conversion unit sets an attribute value corresponding to additional information set to an element in the process model or server model, to the element in the evaluation model corresponding to the element.

12. An evaluation model generation method for generating an evaluation model which evaluates the function or non-function of an IT system based on a system model including a process model which describes processing between processes on the IT system, a server model which describes a physical system configuration of the IT system, and allocations which represent correspondence relations between the elements in the process model and those in the server model, comprising:
