Before applying a software object such as virus detecting software to a customer's real time control apparatus, in order to verify an effect on real time control of the software object, the software object is downloaded from a first web site to a verifying real time control apparatus, and the software object is applied to the verifying real time control apparatus to evaluate whether the customer's real time control apparatus stably maintains the real time control or not. The software object which has been evaluated as one capable of maintaining a stability is uploaded to a second web site, and made to be applicable to the customer's real time control apparatus. Moreover, an observation computer observes whether the verification is performed normally or not.
