Manual Materials Handling MMH creates special problems for many different workers worldwide. Labourers engaged in jobs which require extensive lifting/lowering, carrying and pushing/pulling of heavy materials have suffered increasing rates of musculo-skeletal injury, especially to the back.; This guide is intended to include all activities involved in MMH lifting, pushing, pulling, carrying and holding. Recommendations are provided in the form of design data that can be used to design different MMH work activities.
The guide is divided into two parts. Part I outlines the scope of the problem, discusses the factors that influence a person's capacity to perform MMH activities and / or should be modified to reduce the risk of injuries, and reviews the various design approaches to solving the MMH problem. Part II provides specific design data in six distinct chapters. The seventh chapter of Part II of the guide describes various mechanical devices that are available to aid MMH activities.; The guide is aimed at all concerned with the health impact of MMH activities; occupational health and safety workers; senior human resource managers; ergonomists; workers' compensation lawyers; union representatives.

Artificial intelligence (AI) is playing an increasingly larger role in production and manufacturing engineering. Much of this growth is the result of special-purpose computer controlled machines that are dominating modem manufacturing operations, such as computer numerically controlled machines and robots, and production activities, such as materials handling and process planning. Since a great deal of production and manufacturing engineering knowledge can be put in the form of rules, expert systems have emerged as a promising practical tool of AI in solving manufacturing and production engineering problems. The expert systems allow knowledge to be used for constructing human-machine systems that have specialized methods and techniques for solving problems in a particular application area. Over the years, many expert systems have been developed for applications in manufacturing and production engineering. Most of these expert systems, however, have been of little use to practitioners at large. The primary reason for this limited utility is that in most cases the developers do not divulge the knowledge base and inference mechanism that form the backbone of an expert system. Without the knowledge base, users can only derive a very limited benefit from an expert system and, for all practical purposes, a technical publication describing the expert system for the reader merely becomes a publicity brochure. The reader must either develop his own knowledge base or purchase the system from the developer, often at a substantial cost.

The 1980s have witnessed a tremendous growth in the field of computer integrated manufacturing systems. The other major areas of development have been computer-aided design, computer-aided manufacturing, industrial robotics, automated assembly, cellular and modular material handling, computer networking and office automation to name just a few. These new technologies are generally capital intensive and do not conform to traditional cost structures. The net result is a tremendous change in the way costs should be estimated and economic analyses performed. The majority of existing engineering economy texts still profess application of traditional analysis methods. But, as was men tioned above, it is clear that the basic trend in manufacturing industries is itself changing. So it is quite obvious that the practice of traditional economic analysis methods should change too. This book is an attempt to address the various issues associated with non-traditional methods for evaluation of advanced computer-integrated technologies. This volume consists of twenty refereed articles which are grouped into five parts. Part one, Economic Justification Methods, consists of six articles. In the first paper, Soni et at. present a new classification for economic justification methods for advanced automated manufacturing systems. In the second, Henghold and LeClair look at strengths and weaknesses of expert systems in general and more specifically, an ap plication aimed at investment justification in advanced technology. The third paper, by Carrasco and Lee, proposes an enhanced economic methodology to improve the needs analysis, conceptual design and de tailed design activities associated with technology modernization.
