The design of UML-based sales forecasting application

Abstract

It has now become an important research direction by applying UML as a concept of software development model. The Unified Modeling Language (UML) is a standard modeling language for visualizing the design of a system to make it easier for software developers to build a system. In this research, we designed software for sales forecasting application using best worst method (a new multi criteria decision making method) and adopted RFM concept (recency-frequency-monetary, one of the most popular data mining techniques) based on UML (use case diagram, class diagram, and sequence diagram). The proposed design is expected to accelerate the software development process, reduce complexity and minimize errors while building the software. Finally, through usability testing, sales forecasting application that has been designed based on UML had a user acceptance score of 85.0 (excellent level), so that the design of UML-based sales forecasting application can be used by all users.
