Analytische Informationssysteme werden von Organisationen immer häufiger zur Informationsversorgung und Entscheidungsunterstützung eingesetzt [Fri07]. Vielfach werden hierfür Analytische Informationssysteme mit zu Grunde liegender Informationslogistik (IL)Infrastruktur verwendet. IL-Infrastruktur beschreibt den bei Analytischen Informationssystemen über Insellösungen in Fachabteilungen hinaus g...

A brief historical survey of the development of asymptotic and analytical methodologies for the analysis of spatio-temporal patterns in reaction-diffusion (RD) and related systems is given. Although far from complete, the bibliography is hopefully representative of some of the advances in this area over the past 40 years. Within the scope of this survey, some of the key research contributions o...

the occurrence of natural and human disasters can create heavy casualties in cities and urban areas and such a critical issue makes it inevitable to pay a great deal of attention to the vulnerability and safety aspects of cities and the accessibility to the urban welfare standards from the perspective of passive defense. the geostrategic location of koohdasht city in iran and its vulnerability ...

Effective supply chain distribution network design needs to consider various performance dimensions and product characteristics. Recently, researchers have begun to realize that the decision and integration effort in supply chain design should be driven by a comprehensive set of performance metrics and also product characteristics. In this paper, we relate product characteristics to optimizing ...

Wellbore stability are influenced by many complex factors, and there is no commonly used prediction method on wellbore stability until now. Use of an efficient decision making technique which can take into account several criteria in such conditions is necessary. Referring to traditional wellbore stability analyzing methods, the fuzzy comprehensive evaluation method of predicting wellbore stabi...

Multidimensional data warehouses and OLAP systems do not provide adequate means for dealing with changes in dimension data, changes appearing frequently in dynamic application areas as current business systems. As data warehouses and OLAP tools serve as decision support systems they have to reflect such changes. Temporal data warehouses propose sophisticated modelling tools for covering any cha...

Bitmap indexes are commonly used in data warehousing applications such as on-line analytic processing (OLAP). Storing the bitmaps in compressed form has been shown to be effective not only for low cardinality attributes, as conventional wisdom would suggest, but also for high cardinality attributes. Compressed bitmap indexes, such as Byte-aligned been shown to be efficient in terms of both time...

Mining operations in China are often threatened by frequent water inrushes from confined karst aquifers, We need to evaluate the risk from water-inrush from coal floors in order to have safe production in mines. water inrush risk assessment method based on fuzzy comprehensive evaluation is introduced in this paper. A secondary fuzzy comprehensive evaluation system is constructed to evaluate the...
