This article aims to stimulate research on business process oriented knowledge infrastructures by pointing to the power of visualizations. It claims that business process oriented knowledge infrastructure research is stuck and therefore needs to reinvent and revitalize itself with new impulses. One such stimulus is the use of visualization techniques in business process oriented knowledge infra...

FlowOpt is demonstration software showing how advanced optimization technology can be put at the fingertips of practitioners, who are not experienced in optimization. FlowOpt is a unique combination of optimization technology based on constraint satisfaction techniques with knowledge engineering aspects of extracting formal problem models and with interactive visualization that gives users full...

Let M be an irreducible normal algebraic monoid with unit group G. It is known that G admits a Rosenlicht decomposition, G = GantGaff ∼= (Gant × Gaff)/Gaff ∩ Gant, where Gant is the maximal anti-affine subgroup of G, and Gaff the maximal normal connected affine subgroup of G. In this paper we show that this decomposition extends to a decomposition M = GantMaff ∼= Gant∗Gaff∩GantMaff , where Maff...

FlowOpt is a collection of modules built on top of enterprise performance optimization system MAK€ with the goal to bring unique modeling, optimizing, and visualizing capabilities for production workflows. FlowOpt is based on the concept of nested temporal network with alternatives used to formally describe alternative processes in workflows. The system supports visual design of nested workflow...

Aviation and climate change are often associated. The effects of have increasing impact on the safe operation airports. Due to both weather conditions changes, airport winter maintenance is a significantly important activity airports, especially in areas where harsh season expected. Continuous optimization processes necessary. aim this article present possible way optimize using simulation tool...

In this paper, both the duration and the cost of an activity are modeled as random variables, and accordingly, the cumulative cost at each time point also becomes a random variable along a project’s progress. We first present the new concept of an ‘‘alphorn of uncertainty’’ (AoU) to describe the domain of cumulative cost variation throughout the life of a project and subsequently apply it to as...

This paper describes a simulation tool for the analysis of complex jobs described in the form of task graphs. The simulation procedure relies on the PN-based topological representation of the task graph that takes advantage of directly modeling precedence constraints and other characteristics inherent in Generalized Stochastic Petri Nets (GSPN). The GSPN representation is enhanced with enabling...

Let M be an irreducible normal algebraic monoid with unit group G. It is known that G admits a Rosenlicht decomposition, G = GantGaff ∼= (Gant ×Gaff )/Gaff ∩Gant, where Gant is the maximal anti-affine subgroup of G, and Gaff the maximal normal connected affine subgroup of G. In this paper we show that this decomposition extends to a decomposition M = GantMaff ∼= Gant∗Gaff∩GantMaff , whereMaff i...

The purpose of this research was to determine how team design and project management (planning and tracking) affected planning and design performance and the people involved in the process. A laboratory study was conducted to evaluate three factors: team design (individuals versus groups of three), project support (no project support versus manual project support versus automated project suppor...
