摘要：
This paper discusses how to make a distributed object system flexible so as to satisfy applications' requirements in change of the system environment. The change of the system is modeled to be the change of not only types of service but also quality of service (QoS) supported by the objects. We discuss equivalency and compatibility relations among operations on the basis of QoS. By using the QoS-based relations, we newly discuss a QoS-based compensating way to recover the object from the less qualified state. Finally, we discuss a QoS-based way for replicating objects to make required QoS available. Be using these QoS-based way, we can reduce time and cost for making the system flexible.
