Research on Object Oriented Plan Management System modeling

Under the background that the manufacturing industry is facing the digital transformation, the demand for business modeling is increasingly urgent. Only through business modeling can business processes, business rules and the authority and boundary of roles be sorted out, so as to solve the problem of "information island"among the information systems of various departments of the enterprise. There are many modeling languages/tools that can be applied to business modeling at home and abroad, including flowchart, Event-driven Process Chain(EPC), ICAM Definition Languages(IDEF), Business Process Model and Notation(BPMN) and Unified Modeling Language(UML), etc. Each of these languages/tools has its own advantages and disadvantages. Business modeling under the background of digital transformation is not limited to the traditional "description"of business processes and business rules, but more to find a modeling method, starting from the needs of the organization, step by step to "develop"a business system in line with the expectations of the organization; However, at present, the academic and industrial research on this aspect is very little. Inspired by the history of software development methodology shifting from a process-oriented to an object-oriented method, this paper considers business modeling based on UML and object-oriented method. There are many object-oriented modeling methods. Through research, we find that HarmonySE method can be applied to business modeling to meet the needs of business modeling under the background of digital transformation. Then, it details how to model a plan management system based on UML and HarmonySE methodologies on Astah Professional, a UML modeling tool. Finally, the advantages of business modeling based on UML and HarmonySE are described.
