Cell B1 models the business interfaces and communications between the activities and functions modeled in cell A1. It also models the operations information exchange between the various functional components modeled in A1. Cell C1 models the human interface and the roles of the various human resources involved in the operation and usage of the BRND system, such as the detection team and the staff at the fusion center. Cell A2 models the design constraints for realizing the BRND functions from the designer’s perspective, which includes translating operational and business needs to system functions and logical representations.
Cell B2 models the communications between the various system components and the logical interface representations, including information exchanged, attributes of the information and source and destination information.
Cell C2 models the human interface and the various human resources from the designer’s point of view which translates into activity modeling and activity dependency on human responses or interaction, as well as relationships among various human resources involved in the BRND system usage. Examples would include the modeling of the communication modes, system level communication requirements, logical representations of information transmitted between the
detection team and the fusion center staff and the human-machine interface to receive and send these logical representations.
Cell A3 models the implementation constraints to realize the functions offered by the BRND system from the builder’s perspective. Examples would be hardware and software limitations of the various system interfaces in the BRND system, or processing limitations at the fusion center or other detailed technological constraints. Cell B3 models the details of the communications between the various components and the logical communication interface representations. Examples are the details of the interfaces handling the exchange of information defined by the designer in cell B2.
