Logical architecture approach

The HORSE logical architeture as one cyber-physical system, is deifned by specify the high level  HORSE scenario. This scenario is abstract as it is not based on a specific HORSE pilot case, but on general requirements following from the requirements analysis which has been preceded the architecting process. 

The logical architecture of a complex system as HORSE has been analysed in 5 levels of structural decomposition. 

Use of the Updated Truyens 5 aspect framework (UT5)

The K4+1 framework provides a separation of concerns in terms of software development phases, but does not separate various aspects of the description of a complex software system or information system. For this purpose, we adopt an updated version of the 5 aspect framework of Truyens (abbreviated in this document as UT5). 

The UT5 framework is illustrated in Figure 1. It consists of five interconnected aspects, which we describe below.

We distinguish between five interrelated architecture aspects in the design of the HORSE system:

Software: the software aspect describes the structure of the HORSE software under development; it is described for instance in UML component diagrams.

Process: the process aspect describes the structure of business/manufacturing processes that the HORSE system supports; it is described for instance in BPMN diagrams or UML activity diagrams.

Data: the data aspect describes the structure of data manipulated by the HORSE system, as well as the structure of the concepts that underlie data definitions (concept model); it is described for instance in UML class diagrams.

Organization: the organization aspect describes the structure of stakeholders in the HORSE context, such as operators of the HORSE system and designers of applications supported by the HORSE system; it is described by organigrams and/or actor models.

Platform: the platform aspect describes the structure of the existing technology that is required to run the HORSE system under design in its operating context; this includes both hardware (such as computer systems and robots) and software (such as existing enterprise information systems, middleware and hardware control software).
