Abstract

Provided is a computer program and a control apparatus that can minimize a modification required for a part corresponding to scheduling of a program in response to a change of the program, even when the program is changed. A system monitoring program obtains operation conditions of each layer, to determine whether an operation mode should be changed or not, and selects an operation mode. A system configuration managing program notifies an operation mode to a configuration managing program of each layer. The configuration managing program determines an execution possibility of each program in accordance with the notified operation mode. A system scheduler performs scheduling of a scheduler included in each layer, in accordance with time passage and an event occurrence. The scheduler of each layer performs scheduling of programs allowed by the configuration managing program to be executed.
