Abstract

A disclosed method includes: specifying an activity to be executed, based on process definition that includes plural activities, and that includes a sequence of transitions between activities, wherein each activity includes information representing a device that is operated through a network; first determining, based on the sequence of the transitions, whether or not the specified activity is an initial operation for a certain device whose information is included in the specified activity; and obtaining an access right to the certain device, when determining that the specified activity is the initial operation for the certain device.

First claim

What is claimed is:

1. A computer-readable, non-transitory storage medium storing a program for causing a computer to execute a process, the process comprising:
expanding, to plural transition routes, a process definition that includes a plurality of activities, a sequence of transitions between activities and a transition with a branch, wherein each of the plurality of activities includes information representing a device that is operated through a network and information representing a component that is a program to process an operation to the device;
specifying an activity to be executed, based on the process definition;
first determining, based on the sequence of the transitions, whether a certain device on which the specified activity is to be executed is a device whose information is included in the specified activity and which is different from a device on which activities before the specified activity have already been executed;
upon determining that the certain device is the device whose information is included in the specified activity and which is different from the device on which the activities before the specified activity have already been executed, second determining, for each of the plural transition routes and based on one or plural attributes of one or plural components for one or plural activities included in an exclusive range from obtaining to releasing an access right to the certain device, whether the transition route is in an exclusive mode or a shared mode;
upon detecting that any one transition route of the plural transition routes is in the exclusive mode, setting the exclusive mode for the access right;
upon detecting that any one transition route of the plural transition routes is in the shared mode and no transition route of the plural transition routes is in the exclusive mode, setting the shared mode for the access right; and
obtaining the access right.

2. The computer-readable, non-transitory storage medium as set forth in claim 1 , wherein the second determining comprises setting the exclusive range up to an activity immediately before an activity that operates another device other than the certain device or an activity immediately before an end terminal in the process definition.

3. The computer-readable, non-transitory storage medium as set forth in claim 1 , wherein the process further comprises:
executing a program that is a component for the specified activity, and
upon detecting that a device for a next activity to the specified activity is different from the certain device, or upon detecting that there is no next activity to the specified activity, releasing the access right.

4. The computer-readable, non-transitory storage medium as set forth in claim 1 , wherein the process further comprises: third determining whether or not authorization by a manager is required, based on an attribute of a device for the specified activity.

5. The computer-readable, non-transitory storage medium as set forth in claim 4 , wherein the third determining comprises, upon detecting that the exclusive mode is set for the access right, determining whether or not the authorization by the manager is required.

6. The computer-readable, non-transitory storage medium as set forth in claim 5 , wherein the third determining further comprises:
upon determining the authorization by the manager is required, transmitting an authorization request to a terminal of the manager; and
upon receiving a response representing denial, determining that execution of the specified activity is not allowed.

7. A process execution method, comprising:
expanding, by using a computer and to plural transition routes, a process definition that includes a plurality of activities, a sequence of transitions between activities and a transition with a branch, wherein each of the plurality of activities includes information representing a device that is operated through a network and information representing a component that is a program to process an operation to the device;
specifying, by using the computer, an activity to be executed, based on the process definition;
first determining, by using the computer, based on the sequence of the transitions, whether a certain device on which the specified activity is to be executed is a device whose information is included in the specified activity and which is different from a device on which activities before the specified activity have already been executed;
upon determining that the certain device is the device whose information is included in the specified activity and which is different from the device on which the activities before the specified activity have already been executed, second determining, by using the computer, for each of the plural transition routes and based on one or plural attributes of one or plural components for one or plural activities included in an exclusive range from obtaining to releasing an access right to the certain device, whether the transition route is in an exclusive mode or a shared mode;
upon detecting that any one transition route of the plural transition routes is in the exclusive mode, setting, by using the computer, the exclusive mode for the access right;
upon detecting that any one transition route of the plural transition routes is in the shared mode and no transition route of the plural transition routes is in the exclusive mode, setting, by using the computer, the shared mode for the access right; and
obtaining, by using the computer, the access right.

8. An information processing apparatus, comprising:
a memory; and
a processor using the memory and configured to execute a process, the process comprising:
expanding, to plural transition routes, a process definition that includes a plurality of activities, a sequence of transitions between activities and a transition with a branch, wherein each of the plurality of activities includes information representing a device that is operated through a network and information representing a component that is a program to process an operation to the device;
specifying an activity to be executed, based on the process definition;
first determining, based on the sequence of the transitions, whether a certain device on which the specified activity is to be executed is a device whose information is included in the specified activity and which is different from a device on which activities before the specified activity have already been executed;
upon determining that the certain device is the device whose information is included in the specified activity and which is different from the device on which the activities before the specified activity have already been executed, second determining, for each of the plural transition routes and based on one or plural attributes of one or plural components for one or plural activities included in an exclusive range from obtaining to releasing an access right to the certain device, whether the transition route is in an exclusive mode or a shared mode;
upon detecting that any one transition route of the plural transition routes is in the exclusive mode, setting the exclusive mode for the access right;
upon detecting that any one transition route of the plural transition routes is in the shared mode and no transition route of the plural transition routes is in the exclusive mode, setting the shared mode for the access right; and
obtaining the access right.
