A methodology for the automation of medium or small manufacturing companies

Many products are produced by discrete manufacturing plants in lots of 100 items or fewer. Currently, most small and medium-sized manufacturing companies are far from computer-integrated automation. New computer-integrated manufacturing systems with their associated hardwares require tremendous initial investments that are beyond the means of most small and medium-sized companies. In this paper we investigate how these companies can upgrade and automate their existing facilities at a minimal and viable cost. In Section 2 we discuss main references (books and trade journals) that contain detailed information on software packages for automation. In Section 3 we discuss the criteria for selecting software packages. In Section 4 we discuss how to use the obtained information to create a data base of different alternatives. In Section 5 we outline different areas of manufacturing. For illustrations, we discuss manufacturing planning, intelligent systems, and computer areas. In Section 6 we discuss a new method for the selection of the best alternative using the data base. The method is a simple interactive paired comparison method based on a computer package developed on a personal computer.
