Abstract

SS (Strategic Scanning) is unique, partially subjective, inconsistent, interdisciplinary, vague and multidimensional process. Its description and optimisation suffers from IS (Information Shortage) and heterogeneity. IS eliminates straightforward application of traditional statistical methods. Heterogeneity problems are caused by heterogeneous nature of scanned information structures. Artificial Intelligence has developed some tools to solve such problems. Qualitative reasoning is one of them. It is based on the least information intensive quantifiers i.e. trends. There are four different trends i.e. qualitative values and their derivatives: plus/increasing; zero/constant; negative/decreasing; any value / any trend. The paper studies SS models based on ELEs (Equationless Heuristics). An example of ELE is – If novelity is increasing then confidence is decreasing. A solution of a qualitative model is represented by a set S of scenarios and a set T of time transitions among these scenarios. The key information input into an ELE model is subjective knowledge of experts. A consensus among SS experts is often not reached because of inconsistencies of experts’ knowledge. The SS case study is 12 dimensional (e.g. Freshness, Relevance) and based on 12 ELEs. There are 29 scenarios. || SS (Strategic Scanning) es un proceso único, parcialmente subjetivo, inconsistente, interdisciplinario, vago y multidimensional. Su descripción y optimización adolece de IS (escasez de información) y heterogeneidad. IS elimina la aplicación directa de los métodos estadísticos tradicionales. Los problemas de heterogeneidad son causados por la naturaleza heterogénea de las estructuras de información escaneadas. La Inteligencia Artificial ha desarrollado algunas herramientas para resolver tales problemas. El razonamiento cualitativo es uno de ellos. Se basa en los cuantificadores que requieren menos información, es decir, las tendencias. Hay cuatro tendencias diferentes, es decir, valores cualitativos y sus derivados: más / creciente; cero / constante; negativo / decreciente; cualquier valor / cualquier tendencia. El artículo estudia los modelos SS basados en ELE (heurística sin ecuaciones). Un ejemplo de ELE es: si la novedad aumenta, la confianza disminuye. La solución de un modelo cualitativo está representada por un conjunto S de escenarios y un conjunto T de transiciones de tiempo entre estos escenarios. La entrada de información clave en un modelo ELE es el conocimiento subjetivo de los expertos. A menudo no se llega a un consenso entre los expertos en SS debido a inconsistencias en el conocimiento de los expertos. El estudio de caso de SS es de 12 dimensiones (por ejemplo, Frescura, Relevancia) y se basa en 12 ELE. Hay 29 escenarios.
