This report gives a managerial overview of the Life Cycle Cost Impact Modeling System (LCCIM), which was designed to provide the Air Force with an in-house capability of assessing the life cycle cost impact of weapon system design alternatives. LCCIM consists of computer programs and the analyses which the user must perform to generate input data.…

This paper presents a study on the effects of various data compression methods from the viewpoint of central computer to terminal communications on a large graphics oriented timesharing system, PLATO IV. The desired goal is to increase terminal display speed without significant increase in the transmission error rates. While the major emphasis in…

In this study the advantages and problems involved in using Generalized Data Management Systems (GDMS) to expand the capabilities of information retrieval (IR) systems are investigated. In particular, the design of a Data Manager-1 (DM-1) based system for the Reliability Analysis Center (RAC) at Griffiss AFB, Rome, New York is studied. A design…

A major challenge in higher education is to build evaluation models that first of all spell out various effectiveness measures and then related cost data. The Program Effectiveness and Related Costs (PERC) framework addresses this problem. The five components of PERC are outcomes, costs, students, learning programs, and faculty. An overview and…

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…

A summary of the final two-volume report of the Systems Development Project is contained in this document. The project was commissioned by the National Library of Canada to study and design an integrated information system for the library employing, where feasible, electronic data processing. Included are all of the recommendations of the final…

A cost/benefit analysis of the Public Library Automation Network (PLAN) project was undertaken to evaluate those areas in library technical processing impacted by BALLOTS: searching the data base for catalog copy; cataloging with MARC or original catalog copy input by participating libraries; data entry of original records and modification of…

To support the position that the use of computers can make educational administration more cost-effective, the minicomputer-based information system in the Ridgeway Public School District in New Jersey is described. A model of the information system is included. (JJD)

This report delineates the theory and terminology of data compression. It surveys four data compression methods--null suppression, pattern substitution, statistical encoding, and telemetry compression--and relates them to a standard statistical coding problem, i.e., the noiseless coding problem. The well defined solution to that problem can serve…

Future development and operations of the Korean Educational Computer Network are discussed and possible network layout and cost implications are studied. The Aloha System radio communication, telephone lines and satellite systems are considered as possible alternatives to the present network. The availability of telecommunication facilities and…

Completion of a four-month study of Oakland University's administrative systems needs is reported. It is recommended that the university undertake a major developmental effort to design and install new systems, with particular emphasis on payroll/personnel, general accounting, and student records. Following the development of these systems, a new…

The report describes an experimental study involving an on-line placement system in Boulder, Colorado which permitted applicants to request information from a terminal on any job stored in the computer. Data were collected on applicants referred by the Employment Service: whether or not hired, reason for not being hired if not hired, applicant…

The ERIC network conversion to an OCR (Optical Character Recognition) mode of data entry was studied to analyze the potential effectiveness of OCR data entry for future EPC/s (Editorial Processing Centers). Study results are also applicable to any other system involving decentralized bibliographic data capture and conversion functions. The report…

The project (1968-1973) was undertaken to demonstrate job and earning potential for competitive work of homebound and/or severely disabled persons who otherwise have not benefited from rehabilitation programs as they conventionally exist. In the lifetime of this project, three companies were formed: An non-emergency transportation service for the…

Goodwill Industries of America, Inc. developed a management information system designed to provide rehabilitation workshop managers with information needed to make sound administrative decisions, statistics to measure the outcome of these decisions in terms of service to the handicapped, and the financial resources needed to deliver the services.…
