7
The System Boundary and The Automation Boundary
8
Characteristics Of SystemSystem are made up of
interrelated subsystems (e.g. a nuclear reactor is composed of boilers, reactor components etc.)
Functional decomposition – dividing a system into components based on subsystems (which are in turn further divided into subsystems)
System boundary – the separation between a system and its environment (where inputs and outputs cross)
Automation boundary – separation between the automated part of system and the manual part
9
Research and understand the problem
Verify that the benefits of solving the problem outweigh the costs
Develop a set of possible solutions (alternatives)
Decide which solution is best,and make a recommendation
Design the details of the chosen solution
Implement the solution
Monitor to make sure the youObtain the desired results
The Analysts’Approach to ProblemSolving
