False drops occur in a system of random superimposed coding for edge-notched, punched, and feature cards. Formulae for the false dropping fraction are derived, and figures and tables are given for the calculated values in the most popular scheme. (Author/LS)

This three-part article introduces a population dynamics model of an information processing system. The first part describes the general model and defines the terms used, the second describes the functional relationships between components, and the third explores the hypothesized emergence of increasingly complex, hierarchical information systems.…

Appendix A is concerned with the characteristics of the user communities and of the information service centers as important factors in the representation of an information service system. The basic characteristics of both centers and communities include their number, size, geographic distribution, and scope of interest. These characteristics are…

Four major discussions are presented related to economic issues involved with property rights as applied to computer software and data bases. The first discussion qualitatively compares the relative incentives to computer software producers found in alternative regimes of copyright and trade secrecy. The latter is found to have certain…

This study sought to develop a predictive model for use by educational decision makers in establishing junior colleges, as more needs and costs become known and more precise bases for judgment are needed. Decision-making models were considered suitable for this study. Correspondence with officials produced a valid list of criteria and identified…

The transfer of information through space and time in communication systems is often accompanied by significant delays which give rise to meaningful storage problems. Mathematical models have been developed for the study of these kinds of problems which are applicable to the design of manual, library-type, or mechanized information storage and…

The components of an information system for institutions in higher education are described. The information produced from such a system will be that which is required not only for record keeping and operations but also for planning and budgeting. Technical details are not included, only an overview of the main components of the system as seen from…

The Design of Training Systems (DOTS) project was initiated by the Department of Defense (DOD) to develop tools for the effective management of military training organizations. Phase 2 involved the design and development of three computer-based mathematical models, described in detail in this report. The models described are the System…

The Design of Training Systems (DOTS) project was initiated by the Department of Defense to develop tools for the effective management of military training organizations. Phase 2 of the project, from which this report emanates, involved the design and development of three computer-based mathematical models and their validation. Volume 1 presents…

The purpose of the research described in the report is twofold. First, it is to analyze the relative benefits and costs of on-line computerized placement systems. The techniques developed for such an analysis which might be useful in evaluating other manpower programs are presented. Second, it is to provide a prototype model which shows how…
