Plan executing apparatus, method of plan execution, and computer program product therefor

A plan executing apparatus comprising:

• an executing unit that executes a plan including a sequence of processes;
• a processing state retaining unit that retains a processing state of a target object to be processed according to the plan;
• an execution information retaining unit that retains execution information of a plan in execution;
• an interrupt instruction accepting unit that accepts an interrupt instruction during execution of the plan;
• an interrupting plan formulating unit that formulates an interrupting plan based on the processing state and the execution information on accepting the interrupt instruction;
• and
• an interrupt controlling unit that interrupts with the interrupting plan.

A method of executing a plan comprising:

• executing a plan including a sequence of processes;
• accepting an interrupt instruction during execution of the plan;
• identifying interrupt information relating to execution of an interrupting plan, on accepting the interrupt instruction of the interrupting plan;
• determining whether the interrupting plan is to be executed or not based on a processing state of a target object to be processed according to the plan in execution, the processing state being retained in a processing state retaining unit, execution information of the plan in execution, the execution information being retained in an execution information retaining unit, and the identified interrupt information.

A method of executing a plan comprising:

• executing a plan which is a sequence of processes;
• accepting an interrupt instruction during execution of the plan;
• formulating an interrupting plan on accepting the interrupt instruction based on a processing state of a target object to be processed according to the plan in execution, the processing state being retained in a processing state retaining unit, and execution information of the plan in execution, the execution information being retained in an execution information retaining unit;
• and
• interrupting with the formulated interrupting plan.

A computer program product having a computer readable medium including programmed instructions, wherein the instructions, when executed by a computer, cause the computer to perform:

• executing a plan including a sequence of processes;
• accepting an interrupt instruction during execution of the plan;
• identifying interrupt information relating to execution of an interrupting plan, on accepting the interrupt instruction of the interrupting plan;
• determining whether the interrupting plan is to be executed or not based on a processing state of a target object to be processed according to the plan in execution, the processing state being retained in a processing state retaining unit, execution information of the plan in execution, the execution information being retained in an execution information retaining unit, and the identified interrupt information.
