Owing to the rapid development of electronic computer technique, system engineering has recently proved very useful for managerial problems. In spite of speciality in hospital administration, we can suggest valuable applications of system engineering, but it is necessary to examine the various conditions which enable the application successful. At first, it is explained that system thinking is the basic concept of system engineering in managerial fields. Consideration based on the block diagram at the level of macroscopic national economy reveals that there exist rather definite limitations in activities of medical service organizations and the importance of the requirement analysis in the medical field must be more emphasized. Considering the purpose of hospital administration expressed not in a semantic expression but in a practical detailed form, it can be said that medical marketing which means the investigation and the control of medical demand in the public is the actual top policy in hospital administration. The clerical work in hospitals can be easily substituted by EDPS but it has no radical effect as far as it merely remains in the clerical field. When EDPS would be introduced into the clinical work besides the clerical work, hospital administration system may grow to obtain a powerful effect as a whole system. Both to increase the productivity in hospitals and to decrease the cost of medical services seem possible only by utilizing properly system engineering for large and complicated hospital administrative systems.
