Process support in MetaCASE: implementing the conceptual basis for enactable process models in MetaEdit+
2002
This study concerns the support of information system analysis and design process in a metaCASE environment. We see a process as highly, evolutionary and unstructural in nature, thus requiring the tailorability of user process models and their conceptual basis, process modelling language (PML). In addition to the flexibility needed for guiding various system developers, the CASE environment needs to be enacted using strictly defined environment actions. A distinction between user and environment processes is made, hence distinguishing also their conceptual basis and modelling requirements. The study depicts the realisation of the basic concepts and tools required in modelling a PML and the …
Implementation aspects of interactive multiobjective optimization for modeling environments: The case of GAMS-NIMBUS
2014
Abstract. Interactive multiobjective optimization methods have provided promising results in the literature but still their implementations are rare. Here we introduce a core structure of interactive methods to enable their convenient implementation. We also demonstrate how this core structure can be applied when implementing an interactive method using a modeling environment. Many modeling environments contain tools for single objective optimization but not for interactive multiobjective optimization. Furthermore, as a concrete example, we present GAMS-NIMBUS Tool which is an implementation of the classification-based NIMBUS method for the GAMS modeling environment. So far, interactive met…
