  1. Developing an Objectives-Constraints Tree Creating a graphical representation of design objectives and constraints Taken from engineering design: a project-based introduction by dym & little

  2. The development of an Objectives-Constraints Tree proceeds from the Attributes List and PCC. • The hierarchy of the Objectives-Constraints Tree comes from the results of the Pairwise Comparison Chart. • Primary objectives are listed in the first level of the tree. • Secondary objectives are grouped as subsets of the primary objectives. The same concept holds for subsequent levels of the tree. • Constraints should be listed as a subset of related objectives. • The other objectives and constraints listed in the tree come from the Attributes List. • Objectives are listed in rectangular boxes, and constraints are listed in ovals.

  3. Below is an example (not exhaustive) of an Objective-Constraints Tree for a ladder design. Objectives Constraints
