Evaluation on electronic securities settlements systems by AHP methods

摘要

Accompanying the spread of Internet and the change of business models, electronic commerce expands business areas. Electronic financial commerce becomes popular and especially online security trading becomes very popular in this area. This online security trading has some good points such as fewer mistakes than telephone calls. In order to expand this online security trading, the transfer of the security paper is one the largest problems to be solved. Because it takes a few days to transfer the security paper from a seller to a buyer. So the dematerialization of security papers is one of the solutions. The dematerialization needs the information systems for settling security. Some countries such as France, German, United Kingdom and U.S.A. have been starting the dematerialization projects. The legacy assessments on these projects focus from the viewpoint of the legal schemes only and there is no assessment from system architectures. This paper focuses on the information system scheme and evaluates these dematerialization projects by AHP methods from the viewpoints of "dematerialization of security papers", 'speed of transfer", "usefulness on the system" and "accumulation of risks". This is the first case of evaluations on security settlements systems by AHP methods, especially four counties' systems.
