This paper describes a combination of simulation and knowledge based assessment models used in the operational analysis of future space transportation systems. The model uses knowledge based logic as estimating relationships combined with a process database to estimate the appropriate ground processes, their duration, and their variability. The developed process model is used to populate a simu...

This paper aims at measuring reputational effects for financial institutions by examining a firm’s stock price reaction to the announcement of particular operational loss events such as internal frauds. We conduct at this purpose an event study analysis of the impact of operational loss events on the market values of banks and insurance companies, using the OpVar database (OpData dataset suppli...

This paper addresses the problem of developing an optimisation structure to aid the operational decision-making of scheduling activities in a real-world pipeline scenario. The pipeline connects an inland refinery to a harbour, conveying different types of oil derivatives. The optimisation structure is developed based on mixed integer linear programming (MILP) with uniform time discretisation, b...

With the appearance of the Database Technology the target of an enterprise wide application was joined, respective the integrated management of all relevant data of the enterprise within one database, because on this way a maximal usefulness of the new technology seemed achievable. Several preconditions have been avoided this target ́s achievement. The current self-evident utilization of the dat...

SYNONYMS None DEFINITION A data warehouse (DW) is an integrated repository of data for supporting decision-making applications of an enterprise. The most widely cited definition of a DW is from Inmon [3] who states that " a data warehouse is a subject-oriented, integrated, nonvolatile, and time-variant collection of data in support of management's decisions. " HISTORICAL BACKGROUND DW systems h...

Abstract This paper describes the procedures and operational aspects related to proper storage handling of taxonomic, biogeographic ecological data biological specimens digitised under AMUNATCOLL project. In introductory phase this process, definition metadata is carried out, which formal handler structure, based upon analysis existing standards. The set parameters derived from standard extende...

Real-time database systems support apphcations which have severe operational constraints such as transaction deadlmes and continued operation in the face of failures. in designing real-time database systems, there can be two approaches to meet those constraints. Fit approach is to redesign conventional database systems architecture to replace the bottleneck components. Second approach is to tra...

The BaBar database has pioneered the use of a commercial ODBMS within the HEP community. The unique object -oriented architecture of Objectivity/DB has made it possible to manage over 700 terabytes of production data generated since May'99, making the BaBar database the world's largest known database. The ongoing development includes new features, addressing the ever-increasing luminosity of th...

Database structuring is well understood since decades. The operating of databases has been based in the past on temporal logics and did not yet get an easy to understand formal underpinning. Therefore, conceptions like transaction and recovery are mainly discussed at the logical or operational level. This paper shows that database structuring and functionality can be defined within a uniform la...
