Puerto Rico water resources planning model program description

Because the use of the Mathematical Programming System -Extended (MPSX) to solve large linear and mixed integer programs requires the preparation of many input data cards, a matrix generator program to produce the MPSX input data from a much more limited set of data may expedite the use of the mixed integer programming optimization technique. The Model Definition and Control Program (MODCQP) is intended to assist a planner in preparing MPSX input data for the Puerto Rico Water Resources Planning Model. The model utilizes a mixed-integer mathematical program to identify a minimum present cost set of water resources projects (diversions, reservoirs, ground-water fields, desalinization plants, water treatment plants, and inter-basin transfers of water) which will meet a set of future water demands and to determine their sequence of construction. While MODCOP was specifically written to generate MPSX input data for the planning model described in this report, the program can be easily modified to reflect changes in the model's mathematical structure.

Applications of the generalized information processing system (GIPSY)

The Generalized Information Processing System (GIPSY) stores and retrieves variable-field, variable-length records consisting of numeric data, textual data, or codes. A particularly noteworthy feature of GIPSY is its ability to search records for words, word stems, prefixes, and suffixes as well as for numeric values. Moreover, retrieved records may be printed on pre-defined formats or formatted as fixed-field, fixed-length records for direct input to other-programs, which facilitates the exchange of data with other systems. At present there are some 22 applications of GIPSY falling in the general areas of bibliography, natural resources information, and management science, This report presents a description of each application including a sample input form, dictionary, and a typical formatted record. It is hoped that these examples will stimulate others to experiment with innovative uses of computer technology.

Delaware River basin - water data stations, 1967

This report presents information on station-type activities for acquiring surface-water, ground-water, and quality of water data in the Delaware River basin. The information was collected in 1966 through field offices of the Water Resources Division, U.S. Geological Survey as part of a pilot study for the Office of Water Data Coordination. The cooperation and assistance of various Federal, state, and local agencies (table 1) whose activities are listed is acknowledged with appreciation. No attempt was made during the pilot study to inventory data collected by private industries, but information was available for a number of them. This information is included in the report as an example of the extensive data-collection effort by private groups in the Delaware River basin.
