We discuss a problem arising in the strategic management of IT enterprises: that of replacing some existing services with new services without impairing operations. We formalize the problem by means of a Mathematical Programming formulation of the Mixed-Integer Nonlinear Programming class and show it can be solved to a satisfactory optimality approximation guarantee by means of existing off-the...

Current research work in e-learning and more specifically in the field of CSCL (Computer Supported Collaborative Learning) deals with design of collaborative activities, according to computer-interpretable specifications, such as IMS Learning Design, and their posterior enactment using LMSs (Learning Management Systems). A script that describes such collaborative activities is typically designe...

When humanitarian workers embark on learning and dialogue for linking geoinformation to disaster management, the activities they confront are usually more difficult than interesting. How to accelerate the acquisition and deployment of skills and tools for spatial data collection and analysis, given the increasingly unmanageable workload of humanitarians? How to engage practitioners in experienc...

As automation of business processes becomes more complex and encompasses less-structured domains, it becomes even more essential that the knowledge used by these processes is verified and accurate. Most application development is facilitated with software tools, but most business rules and expert systems are developed in environments that provide inadequate verification testing. This paper desc...

The objective of the Poseidon Coastal Zone Management System project is to develop a distributed data and software architecture to locate, retrieve, utilize (in simulations and analysis), and visualize information about the coastal ocean environment. The work described in this paper concentrates on the issues related to efficiently identifying and creating the data needed for a given task. Sinc...

Typically the track network data model is maintained as an afterthought or with primitive tools or complex procedures. A software tool set to manage unified set functions needed to manage a track network is a sizable, complex and costly endeavor and thus difficult to justify. Bentley Systems, a developer of engineering systems software, has had the opportunity of combining work in the highway a...

Decisions regarding water management issues are by nature complex; they involve balancing the three interconnected pillars of sustainability: social welfare, economic needs and the needs of an ever-changing environment. Moreover, such decisions may include controversial or poorly understood issues, such as the role of equity or property rights, as well as conflicts of interest. Due to the uncer...

We present the problem of notation selection in mathematical computing environments. For various reasons, users may require mathematical software to employ different output notations for the same expression in a variety of settings. How this can be managed in a general way is the subject of this report. We describe a software tool that can be configured extensively to allow mathematical package...

organizations have taken a mistaken view of KM, deploying a software tool, and expecting employees to be motivated more or less by design to share knowledge. In actual fact, however, KM has to be undertaken by means of an all-embracing process through which the knowledge that is in the organization is discovered and used correctly. However, those organizations that are aware of the need to enac...

STRATMAS is a software tool for simulating and optimizing military and civil operations such as humanitarian assistance and peace keeping operations. These kinds of scenarios are fairly complex and optimizing them gives rise to heavy computational burdens. It is of interest to enhance the computational capacity to be able to perform optimizations with higher spatial and temporal resolution. Thi...
