1 ECIV 360 Civil Engineering Systems Prof. Bill X. Yu Spring, 2009 Part 1 Overview of Engineering Systems Requirements A system vision on engineering design, operation and management Systems System Collection of things that function together to fulfill specific purpose of function components that are connected by some type of interaction or interrelationship Examples an automobile, an urban mass transit system, state or federal government System Hierarchy Needs to identify system, subsystems and their interactions The degree of definition is clearer at subsystem level Easier to optimize the subsystem than the whole system Systems approach A framework for analysis and decision making A general problem-solving techniques that brings objectivity in the planning/design process Select the best course of action that will accomplish a prescribed goal by broadening the information base of decision maker; better understanding the system and interrelations; prediction of the alternative courses of action
