Decision Support System (DSS) tools provide useful information to decision makers. In an Extended Enterprise, a new goal, changes in the current objectives or small changes in the extended enterprise configuration produce a necessary adjustment in its decision system. A DSS in this context must be flexible and agile to make suitable an easy and quickly adaptation to this new context. This paper proposes to extend the Hierarchical Production Planning (HPP) structure to an Extended Enterprise decision making context. In this way, a framework for DSS in Extended Enterprise context is defined using components of HPP. Interoperability details have been reviewed to identify the impact in this framework. The proposed framework allows overcoming some interoperability barriers, identifying and organizing components for a DSS in Extended Enterprise context, and working in the definition of an architecture to be used in the design process of a flexible DSS in Extended Enterprise context which can reuse components for futures Extended Enterprise configurations.

Resumen PONS, J.M., VICENS, E., TROYA, L. y LUCENA, G., Revisión de los taxa de rudistas de Luis Mariano Vidal (1842-1922. La revisión de los 323 registros de bivalvos rudistas de la colección Vidal, depositada en el Museu de Geologia de Barcelona (MCNB), ha permitido identificar y refigurar treinta y tres ejemplares holotipo o sintipo correspondientes a veinte especies establecidas por Vidal. De entre ellas, trece se consideran especies válidas, cuatro resultan sinónimos de especies descritas anteriormente y tres (una de ellas no figurada) no muestran suficientes caracteres para su identificación. No han sido localizados los cuatro sintipos de Hippurites castroi, especie atribuida actualmente al género Hippuritella, ni los otros dos ejemplares publicados posteriormente por el autor. Tampoco se localizaron tres de los cuatro sintipos de Hippurites maestrei, especie tipo de Hippuritella. En cambio, sí se localizaron los ejemplares descritos como Sphaerulites posae pero no figurados. Por otro lado, se han identificado y se refiguran doce ejemplares, sintipos o figurados como nuevas especies por otros autores (Matheron y Douvillé) a partir de material facilitado por Vidal; en su mayoría, sobre una de las partes en que fueron seccionados los ejemplares para su estudio y que fue devuelta a Vidal. Asimismo, se han identificado y se documentan diecisiete ejemplares figurados por Douvillé, también en su mayoría partes de ejemplar.Palabras clave: Colección Vidal, Rudistas, Taxonomía. AbstractThe revision of the 323 register numbers of rudist bivalves in the Vidal Collection, kept at the Museu de Geologia de Barcelona (MCNB), allowed the identification and re-figuration of thirty-three holotype or syntype specimens corresponding to twenty species established by Vidal. Among them, thirteen are considered as valid species, four resulted to be synonymous with other senior species, and three (one not figured) do not display enough characters to be properly identified. The four syntypes of Hippurites castroi, currently attributed to genus Hippuritella, have not been localised, nor the other two specimens subsequently figured by the author. Similarly, three of the four syntypes of Hippurites maestrei, type species of Hippuritella, have not been localised. Contrarily, the specimens described as Sphaerulites posae but not figured, were localised. On the other hand, twelve specimens, syntypes or figured as new species by other authors (Matheron and Douvillé), have also been identified and are re-figured; most of them are part of the specimens that were sectioned for study and then returned to Vidal. In addition, other seventeen specimens figured by Douvillé have been identified and are documented; most of them also being part of a sectioned specimen.
