Taiwan Island is surrounded by seas in all directions of its territory. Because of the tortuous coast, harbors and bays, in addition to the government¡¦s policies to mainland China opening gradually, the piecemeal activities of smuggling, illegal immigrations and so on in the early period have become organizational, grouped large-scale ones today. This transition has influenced national security and socially public order. Coast Guard Administration has responsibilities for prevention from smuggling, illegal immigration and attacking crimes. Hence, being the front line staff for law enforcement should know how to apply and build all kinds of high-tech equipment and systems well in order to promote the effectiveness of investigation, surveillance, law enforcement efficiently. Radar system is an efficient instrument for the investigation of smuggling, search and rescue and the defense of national marine right. It can provide the movement of certain targets on seas in twenty-four hours to the staff on duty all day who may ascertain some suspicious scenarios as soon as possible and adopt the way of deploying and placing armed force in advance to keep sea areas in safety. The smooth and reliability of maintaining for radar system both influence on the staff who try to control dynamic targets directly and the dispatch for all subordinate units¡¦ maneuverable manpower indirectly at the same time. Architecture-Oriented Coast Guard Radar Maintenance and Operation Management Model (abbreviated as AORMOMM below) addressed in this study is a practical mold which consists of six fundamental diagrams in accordance to the structure-behavior coalescence (SBC) architecture. It demonstrates multiple perspectives on the maintenance of radar system completely. AORMOMM integrally describes the structure and behavior and helps all related supervisors and employees in an organization keep whole perspectives well for the maintenance and operation of radar system through this model. Because we have already integrated the organization of managing and operating radar system, information systems and the processes of operation into AORMOMM, exercising whom will assist all departments in an organization to communicate with each other in common consensuses efficiently in their work and makes the transmission of information more transparently then help employees obtain better efforts when learning how to deal with their affairs. In addition, taking advantage of AORMOMM to maintain and manage will make governmental organizations gain better qualities when putting the maintenance and operation of radar system into practice.
