Über dieses Buch

Mastering the complexity of innovative systems is a challenging aspect of design and product development. Only a systematic approach can help to embed an increasing degree of smartness in devices and machines, allowing them to adapt to variable conditions or harsh environments. At the same time, customer needs have to be identified before they can be translated into consistent technical requirements. The field of Systems Engineering provides a method, a process, suitable tools and languages to cope with the complexity of various systems such as motor vehicles, robots, railways systems, aircraft and spacecraft, smart manufacturing systems, microsystems, and bio-inspired devices. It makes it possible to trace the entire product lifecycle, by ensuring that requirements are matched to system functions, and functions are matched to components and subsystems, down to the level of assembled parts.

This book discusses how Systems Engineering can be suitably deployed and how its benefits are currently being exploited by Product Lifecycle Management. It investigates the fundamentals of Model Based Systems Engineering (MBSE) through a general introduction to this topic and provides two examples of real systems, helping readers understand how these tools are used. The first, which involves the mechatronics of industrial systems, serves to reinforce the main content of the book, while the second describes an industrial implementation of the MBSE tools in the context of developing the on-board systems of a commercial aircraft.

Chapter 1. Introduction
Abstract
The literature about the Systems Engineering are so wide that one might feel lost in reading. Realizing the context where this methodology is introduced and currently refined might help in mastering its main contents. This introduction briefly describes the approach proposed in this handbook to introduce the topic, through a linear rationale, developed through the chapters, and by means of a couple of examples, aimed at simplifying the understanding.

Chapter 2. The Systems Engineering
Abstract
Many definitions of the Systems Engineering are proposed, and analyzing some differences between them help to highlight contents and open issues, as they are described in this chapter. Nevertheless, a short historical outline could be helpful in appreciating some characteristics of this methodology, which are even more detailed by a wide literature, herein briefly described. Furthermore, an overview of technical standards dealing with the Systems Engineering is added, to define a roadmap for a deeper education in this field.

Chapter 3. The Methodology of Systems Engineering
Abstract
It is well known that the amount of contents related to the Systems Engineering often makes confused the users about their suitable exploitation in a linear product development process. Therefore, in this first technical chapter, some basic concepts are defined and some typical models of product development are shown. They are compared and distinguished from some architecture frameworks currently applied to define the system capabilities and some crucial views. A sketch of the main steps of the Systems Engineering implementation is finally drawn, together with a list of some proprietary approaches proposed by societies, companies and software vendors for its straight deployment. Tools and languages are even described, together with some engineering methods and the SysML language is used as a relevant example to describe the main diagrams applied in functional modeling.

Chapter 4. Systems, Customer Needs and Requirements
Abstract
A preliminary and relevant step of the whole process includes a complete collection of customer needs and a suitable elicitation of requirements. This activity is never trivial and requires to be suitably formalized. This is done by resorting to the test cases of this handbook. In the meanwhile, the role of stakeholders is even investigated and defined. Requirements are then defined, classified and categorized for a better implementation of the MBSE. A direct implementation of requirements analysis is performed for the two examples.

Chapter 5. Operational Analysis
Abstract
Since this chapter, the different analyses performed by following the MBSE approach are proposed and deeply described. In the Operational Analysis, the system mission, context and scenarios are basically studied. The aim of the chapter is showing first how the Operational Analysis is deployed by resorting to some SysML diagrams. It is then applied to the so–called didactic test case, by resorting to a first software tool. It is then applied to the industrial test case, by exploiting some other tools, to show at least briefly, some differences. At the end of chapter, the main items of the Operational Analysis are resumed.

Chapter 6. Functional Analysis
Abstract
The next step of Functional Analysis is herein investigated. The existing relation between Operational and Functional Analyses is first defined. The implementation of the Functional Analysis is then performed, through the SysML. How the traceability and the requirements allocation are assured is shown. The system behavior is fully analyzed. The functional architecture is then derived, for the two test cases. Finally, the main items of the Functional Analysis are resumed.

Chapter 7. Logical Analysis
Abstract
Before that a real architecture of system could be defined, by selecting some suitable components, available on the market, it is suggested to describe the Logical architecture of the system, to investigate the most promising solutions available in terms of exploitable technology. This leads to perform a Logical Analysis, as is herein described. Relations between Functional and Logical Analyses are investigated. Examples are exploited to show some properties of this analysis. At the end of chapter, the main items of the Logical Analysis are resumed.

Chapter 8. Physical Analysis
Abstract
This main activity of engineering is described and analyzed within the frame of the whole product development and in connection with the Functional and Logical Analysis. The two test cases are explored to describe different examples of physical modeling, considering the dynamic behavior of a rotor, actively suspended and the performance in de-icing activity of the on-board system of the commercial aircraft selected for this example. Some numerical methods are even described as they are applied in the two proposed test cases.

Chapter 9. Heterogeneous Simulation
Abstract
As a matter of facts, interoperating tools and integrating the functional and physical modeling of systems within a unique toolchain is one of the most challenging issues of the Systems Engineering technology as is currently known. Therefore, this topic is analyzed in this chapter, one that the set of analyzes required was performed. Strategies, tools, limitations and benefits of the heterogeneous simulation are here analyzed, even through the two test cases.

Chapter 10. System Verification and Validation (V&V)
Abstract
A preliminary overview on the connection between Application Lifecycle Management and Product Lifecycle Management is proposed, by introducing the contents and the strategies of the Verification and Validation activities. The chapter should allow the Reader distinguishing the two activities and even the tools and the goals related. A comparison between the typical approaches applied in Software and Hardware Engineering, respectively, is briefly deployed. A preliminary relation with the RAMS analysis, dealing with Reliability, Availability, Maintainability and Safety, is discussed, especially in the two test cases.

Chapter 11. Systems Engineering and Product Lifecycle Management (PLM)
Abstract
This handbook is mainly aimed at describing the activities related to the ALM, applied to the industrial product coming from a material processing. Nevertheless, a suitable integration of tools and processes with the PLM is obviously required, as is herein briefly described. A Configuration Control Management is strictly required to track the changes applied to the developed product along the lifecycle. This needs to build up a platform which includes the tools to be interoperated. Exploring how this might be done is herein proposed.

Chapter 12. Conclusion
Abstract
At the end of this path a short resume is proposed, to define the lesson learnt and the next work to be done to improve the expertise within the Systems Engineering.
