In this book the author aims to introduce human factors professionals to the complexities, challenges, and procedures of systems design. The author defines systems as ". . . an interacting combination, at any level of complexity, of people, materials, tools, machines, software, facilities, and proce

β¦ Synopsis
The potential catastrophic impact of global problems on contemporary society has received a great deal of public attention in recent years. Many of these problems can only be solved, not just by technological innovation, but also by changing human behavior (e.g., having less children, producing less waste, consuming less electricity and water). This paper describes how the discipline of human factors (or ergonomics) can play a unique role in helping to solve such global problems. Two illustrative design principles-behavior-shaping constraints and salient, immediate feedback-are discussed. In addition, examples of how these principles can potentially be applied to the following problems are provided: conserving energy expended by desktop computers; reducing photocopier paper wastage; conserving residential utility consumption; and reducing water wastage from faucets. If more products were designed in this fashion, then the aggregate contributions could amount to a worthwhile improvement in global problems.

A new algorithm is presented for the location of the global minimum of a multiple minima problem. It begins with a series of randomly placed probes in phase space, and then uses an iterative Gaussian redistribution of the worst probes into better regions of phase space until all probes converge to a
A new rule is presented to estimate strength-reduction factors in single-degree-of-freedom elastoplastic oscillators, in which reduction factors depend only on displacement elastic spectra, so they are not an explicit function of structural period. It is found that the proposed rule yields good resu
