Systems Engineering: What And Why?

INTRODUCTION

The fundamental principal of system engineering is for application of development of

complex system .Topics include requirements analysis, concept definition, system synthesis,

design tradeoffs, risk assessment, interface definition, engineering design, system integration,

and related systems engineering activities. The course defines the breadth and depth of the

knowledge that the systems engineer must acquire concerning the characteristics of the

diverse components that constitute the total.

1. WHAT IS SYSTEM ENGINEERINGSystems Engineering is a subject that has developed relatively recently. Its main aim is to

consider engineering systems as a whole rather than just to concentrate on one particular

component within them. Systems Engineering in robotics. Autonomous self-assembly of

modules gives new form and function to solve previously impossible problems. Systems

engineering is a methodical, disciplined approach for the design, realization, technical

management, operations, and retirement of a system. A system is a construct or collection

of different elements that together produce results not obtainable by the elements alone. This

aim arises from the fact that almost everything around us that we use daily is a relatively

complex system made up of a number of different components, which are likely to includemechanical components, electronic components, computer hardware/software and possibly

other components as well.To try to explain in a little more detail, Systems Engineering

covers the mathematical modelling, design and analysis of systems, concentrating

particularly on how the different components in a system fit together and ensuring that the

system is designed such that all components interact together in an efficient way.

2. WHY SYSTEM ENGINEERINGSystem engineering have methods and tools that enable faculty and students to model,

design, analyze, and optimize human-made and physical systems within a broad array of

applications. SE methodologies usually account for such real-world complexities as

uncertainty, constraints, multiple objectives, and the relationships among the various parts or

subsystems that constitute the system being studied This, in turn, is driving the need for more

sophisticated SE methods to manage this complex and interconnected world. Thus, Systems

Engineering cuts across the traditional engineering departments as a discipline that enables

building, analyzing, or managing a systembe it electrical, mechanical, chemical, biological

or one involving business processes and logistics. Methodological approaches involving

mathematical or computer simulation models, designing feedback controllers, dealing with

uncertainty and risk, or optimizing performance are universal and demand skills that the

Systems Engineer can provide.

3. SUMMARYThe process provides an increasing level of descriptive detail of products and processes with

each system engineering process application. The output of each application is the input to

the next process application.

The system engineering process is the engine that drives the balanced development of system

and processes applied to each level of development, one level at a time.
