Electric companies need effective methods to visualize information. The Electric Union in Cuba works on the development of a Geographic Information System (GIS) with a conceptual basis that responds to the different user requests. For this, the research objective is to develop a model for the management of geospatial data, with the use of artificial intelligence techniques, as support for decision making in the Cuban electric sector. As a first step, a lightweight ontology that endows a conceptual basis is elaborated. To achieve automatic queries, a Case-Based Reasoning System is developed. The case database contain the description of static queries previously made in the form of cases. Each query is made up of eleven fundamentals traits derived of the completed knowledge engineering performed, of which: eight are predictors and three are objectives. The final quality of the GIS is verified according to the quality standards of ISO 9126:2002 norm. The system is applied in all electric companies of the country in the different areas that affect the transmission processes. The results of field validation evidence the feasibility of the proposal.

The objective of this article is to develop a procedure to the management control, based in a balanced scorecard with focus of process, which contribute to improve the efficiency and the efficacy in the Comercializadora Divep Sancti Spíritus Enterprise. A procedure, based in the Balanced Scorecard, that integrates the process definition into the planning is defined. As results, the key factors of the enterprise success associated to the four perspectives of the Balanced Scorecard which are linked through the cause-effect relations are defined and the strategic map that contribute visualizing and communicating the enterprise strategy is obtained. The indicators are evaluated with the assistance of the software GECAS version 3.0. The implementation of the procedure contributed to improve the efficiency and the efficacy in the Comercializadora Divep Sancti Spíritus Enterprise. [ABSTRACT FROM AUTHOR]

New computing and communications technologies have allowed information to become a key factor of success for organizations. This work is intended at carrying out an analysis of the evolution and the concept framework of information systems. Matching points from different authors regarding definitions and the main deficiencies to be solved are defined. A bibliographic analysis was performed in order to draft the concept framework. It was concluded that the information system is a dynamic and open one turning the data into information to be relayed inside and outside the organization in order to support command and decision making processes.
