This material was shipped to Fenwick Library Special Collections, George Mason University, Fairfax, VA on 23 October 2000. ANNOTATION: This was the first publication dealing with ISM (Interpretive Structural Modeling). It gives the mathematical basis for writing software which will put interpretive structural models into graphic form. The bordering theorem is also included in an incomplete form in Appendix 1, with notations (supplied by the author, at a later date) on his other writings which contain the complete bordering theorem in its final form. This book is also available from the Fenwick Library, George Mason University and from Library of Congress, Washington, D.C., using Call No. QA402 .W37. We have a complete file copy, photocopied from the book, into which are marked the typographical and other errors. Chapter Seven and the Appendix of this book are now obsolete; superseded by Warfield's Implication Structures for Systems Interconnection Matrices, and his 1976 book Societal Systems: Planning, Policy and Complexity.
