Requirements Definitions of Robotics Automation Using the Behavioral Patterns Analysis (PBA) Approach: The Production Cell System

Experience is showing several problems with use cases such as lack of a precise definition that led some companies to develop their own version, lack of notion of atomicity, and considering only the user interface. If the analyst misinterpreted or neglected some structural or behavioral aspects, the resulting software system may not display the correct behavior or may ungracefully terminate. The use of events in the behavioral pattern analysis approach (BPA) provides cohesive integration between the static abstraction (classes) and the dynamic behavior. This integration may partially or totally eliminate the pre-mentioned problems. This paper presents the use of BPA to model a robot system in a manufacturing setting
