Integration Engineering for System Effectiveness
Description / Abstract:
INTRODUCTION
Integration Engineering can best be described by the German word “Zeitgeist” meaning trend of the time. Like a trend, the key to application of the techniques of integration is "how much and when." The application requires a rhythm with the program and a sense of timing for maximum system effectiveness.
System effectiveness has been approached in three different ways by practitioners. The usual approach is to develop and exercise a mathematical model for mission accomplishment. With this, a figure of merit is the key to program control. The second approach is to set the design criteria and control the program for minimum cost. A third, not often recognized, approach is to control the development program by means of design, production, and management operational criteria that have been found to yield successful programs. This paper will meld the three approaches so as to yield a program that can be characterized as having satisficing integration. This has been called “satisficing” or reaching a solution that satisfies rather than striving for an optimum with the attendant penalties in cost and energy.
Integration Engineering may be defined as in MIL-STD-499 (1) as "timely and appropriate intermeshing of engineering efforts and disciplines to ensure their full influence on the system design and technical program." Webster's New World Dictionary states that "integrate” means "to make whole or complete by adding or bringing together parts.” Too often in the past this has been the method of integration. Plans, specifications, and drawings would be stapled together with a cover sheet. This may have satisfied the definition of “integration,” but it did not yield an integrated design or technical program. The concept of integration engineering is aimed at influencing the production of a coordinated and cohesive system and program to produce it. This requires clear definition of the constituent system and program elements and analysis of the interfaces between the elements in order to create a unified system and program. This paper will describe the author's approach to such an integration.
