Abstract

An IT system is operated reflecting a management policy accurately. In a method for determining allocation of IT resources of an IT system shared by divisional operations of an organization based on management resources allocation among divisions in the organization, the method comprises a first and a second steps of resource allocation. In the first step, management resource allocation for each of the divisional operations is determined so as to optimize a value of an operational objective based on the assumption that IT resource allocation is equal among the divisional operations and based on the management resource allocation among the divisions of the organization. In the second step, IT resource allocation for each of the divisional operations is determined so as to optimize the operational objective value based on the management resource allocation for each of the divisional operations determined in the first step.

Claims

1. A method for determining IT resources allocation of an IT system, which are shared by divisional operations of an organization based on management resources allocation among divisions in the organization, the method comprising:

a first step of determining, so as to optimize a value of an operational objective, management resource allocation for each of the divisional operations based on the assumption that IT resource allocation is equal among the divisional operations and based on the management resource allocation of the divisions in the organization; and

a second step of determining, so as to optimize the value of the operational objective, IT resource allocation for each of the divisional operations based on the management resource allocation for each of the divisional operations determined by the first step.

2. The method for determining allocation of IT resources according to claim 1, wherein management resource allocation for each of the divisional operations is again determined by the first step using the IT resource allocation determined by the second step and then the IT resource allocation for each of the divisional operations is redetermined by the second step.

3. The method for determining allocation of IT resources according to claim 1, wherein the value of the operational objective includes at least one of an operation lead time, an operational accuracy, an operational cost, a profit, a sales amount, a per capita profit and a per capita sales amount, and wherein the value of the operational objective is computed using an objective function predetermined for the organization.

4. The method for determining allocation of IT resources according to claim 1, wherein the management resources include a number of staff members in each division.

5. The method for determining allocation of IT resources according to claim 1, wherein the management resources include a number of staff members in each division weighted by a capability.

6. The method for determining allocation of IT resources according to claim 1,

wherein the IT resources comprise a network to which a plurality of terminals are connected, a computer to perform processing, and a storage system storing data used for the processing;

and

wherein the IT resource allocation comprises allocating at least one of a network bandwidth, CPU usage in the computer, memory usage in the computer, and throughput of the storage system.

7. A computer system which comprises a computer performing processing, a network to which the computer and a plurality of terminals are connected, and a storage system storing data used for the processing performed by the computer and which is shared by divisional operations of an organization, the system comprising:

a first policy transformation module determining, so as to optimize a value of an operational objective, management resource allocation for each of the divisional operations based on the assumption that IT resource allocation is equal among the divisional operations and based on management resources allocation of divisions in the organization; and

a second policy transformation module determining, so as to optimize the value of the operational objective, IT resource allocation for each of the divisional operations based on the management resource allocation for each of the divisional operations determined by the first policy transformation module,

wherein the first policy transformation module and the second policy transformation module determine IT resource allocation of the computer system.

8. The computer system according to claim 7, wherein the first policy transformation module again determine management resource allocation for each of the divisional operations by using the IT resource allocation determined by the second policy transformation module and then the second policy transformation module redetermine the IT resource allocation for each of the divisional operations.

9. The computer system according to claim 7, wherein the value of the operational objective includes at least one of an operation lead time, an operational accuracy, an operational cost, a profit, a sales amount, a per capita profit and a per capita sales amount, and wherein the value of the operational objective is computed using an objective function predetermined for the organization.

10. The computer system according to claim 7, wherein the management resources include a number of staff members in each division.

11. The computer system according to claim 7, wherein the management resources include a number of staff members in each division weighted by a capability.

12. The computer system according to claim 7, wherein the IT resource allocation comprises allocating at least one of a network bandwidth, CPU usage in the computer, memory usage in the computer, and throughput of the storage system.
