New Criteria Added to the Structure of the Catalogue

In addition to the criteria considered in the initial version of the catalogue, new criteria were incorporated to the structure. This new set of features can be understood as new descriptive criteria, since they contribute to the characterization of the analyzed assets. Figure 3 suggests this idea. The aim of these new criteria is to determine the relation of the industrial assets considered with the existing local population. This relation, and the potential synergies issuing from it, are of great interest when the possible reuse of one asset is being discussed. In fact, as previously mentioned, the interest of including this group of criteria was detected through the use of the catalogue as part of a global methodology, in which the information contained in the catalogue supports multi-criteria decision structures for the selection of the most appropriate new uses for these kinds of goods [19]. As in the case of the previously exposed criteria groups, the nature of the information contained in each field is also indicated in Figure 3.

Table 1 illustrates how the eight criteria added to the structure of the catalogue try to define the relation of the industrial assets that were analyzed with the local population. Thus, two implicit classification levels can be identified through these eight criteria. First, they allow differentiating between rural and urban environments. Then, inside each of the two main categories, new particular situations are considered. For rural environments, the relationship with the local population is then analyzed. In the case of assets located in urban environments, the size of the population center is indicated. Special aspects are also considered, such as the special role that the province capitals have in each region, and the number of inhabitants of the nearest population center, according to the data provided by the National Statistical Institute of Spain [23].
