On successful completion of this module students should be able to:
1. Display an understanding of the processes and tools required throughout the engineered system lifecycle.
2. Be able to decompose a product requirement, investigate alternative designs and analyze their characteristics using a variety of systems engineering techniques.
3. Be able to design and analyze the performance and reliability characteristics of a software based embedded control system.
4. Have a critical understanding of the interaction and tradeoff between software and hardware elements of a (mechatronic) system.
5. Be able to display an appreciation of the characteristics of traditional and novel approaches to systems control afforded by the presence of software.
System engineering is a creative but rigorous and analytical discovery process and this module will consider the processes and tools required throughout the product lifecycle with particular emphasis on software controlled mechatronic systems. The module will consider the 7 steps in the INCOSE (International Council on Systems Engineering) SIMILAR process: State the problem, Investigate alternatives, Model the system, Integrate, Launch the system, Assess performance, and Re-evaluate. Within these aspects the module will include cross domain modelling and analysis techniques aimed at the development of systems that contain significant software elements. The module will address non-functional requirements including safety, quality and complexity.
a. Quality management systems and standards
b. Process and management tools; Managing product and project complexity
2. The product life cycle
a. Requirements engineering:
Functional decomposition/reasoning, functional flow diagrams, process charts, design synthesis, decomposition and COTS components.
Value Analysis including tear-down, trade studies.
b. Modelling and simulation
State based, Continuous and Hybrid systems concepts
Modelling Systems and Software for example SysML
Model based reasoning using quantitative and qualitative approaches
c. Reliability and maintainability
Standards e.g. IEC 61508; Failure Modes Effects and Criticality Analysis; Fault Tree Analysis; Reliability Block Diagrams; Life Data Analysis concepts (Weibull Analysis) MTBF/MTTR; Current software analysis tool capability;
d. Diagnosis, Diagnosability, Prognosis
On-board and workshop requirements; Sensing and observation cost and complexity trade-offs; Model based and other approaches.
e. System integration, security and performance analysis
3. Software at the heart of the system
a. Real and near-real time software and operating systems characteristics
b. Multi-level and networked architectures
Data networks; bus architectures; inter device communication;
c. Control of highly nonlinear and complex systems
AI Toolbox methods overview and their characteristics; Fuzzy logic; Expert Systems; Case Based Reasoning; Neural Networks.
4. In depth worked example
An example real embedded control system will be studied in detail from concept to implementation and maintenance providing insight to each part of the process, the stakeholders, tools and processes involved.
