To expand software easily, the construction of large-scale widely distributed systems should be based on the concept of autonomous decentralized systems. It is proposed that the software expansion methods should be variable, according to the characteristics of software. Two types of software, online control software and human service software, are derived from the analysis of software characteristics. The software expansion process is then derived, and online replacement is discussed.>
