Many implementations of decision support systems suffer from a lack of flexibility, that is, they are built for a specific application domain. For different application domains, large portions of the particular decision support system have to be reimplemented from scratch. As object-orientation allows the construction of flexible software architectures, this paradigm was applied in the realm of...

We develop a system for managing inventory for Jeppesen Sanderson, Inc. — a major provider of aviation information products. The problem involves determining order quantities for charts used in flight manuals. These charts contain essential safety information that changes frequently, making standard methods for inventory management ineffective. We formulate the problem as a dynamic programming ...

In recent years, global software development has become a common practice. Technological advances and expected benefits such as saving personnel costs and accessing a larger pool of resources have led to software development that is now often spread across several locations all over the world. However, distributed development also entails a number of risks and problems, for instance in terms of...

We have developed the GLEE system for execution of guidelines encoded in the GLIF3 format. This system can be integrated with a local clinical information system through standard interfaces to EMRs and clinical applications. The execution model of GLEE takes the "system suggests, user controls" approach. A tracing system is used to record the state of guideline steps and their transitions. GLEE...

in today’s business competitive world, decision makers of companies try to employ standard, efficient, theoretical and operational proven methods as a competitive advantage for making their critical strategic business decisions in order to survive in their industry. in this paper, a hybrid model based on fuzzy analytic hierarchy process (fahp) and artificial neural network (ann) is presented. t...
