However, for these assets to continue to pay dividends they must be converted to a form suitable for computer-aided applications such as CAD/CAE/CAM, simulation-based design, and virtual prototyping. Manually converting legacy engineering drawings into CAD-file format has become common practice to enable reuse of this legacy data and for maintaining it more cost effectively. However, directly reusing legacy drawings for many modem computer-aided applications is not feasible if the complete product data is not properly recovered (e.g., 3D true-CAD solid model). In this paper, a multiple-level drawing conversion methodology, R23D, is introduced to supply a complete solution to this problem. R23D, based upon semantic drawing interpretation modules, incorporates promising results in vectorization and 3D reconstruction to provide an integrated envir...

These items forge relationships between people, information, material, and machines to make a system. In this report, we refer collectively to these items as constraints. Constraints initiate, enable, govern, and limit the behavior of objects and agents to accomplish the goals or purposes of a system. If we want to change the behavior of a system for whatever reason (e.g., improve its performance, efficiency, or effectiveness) we need to know what the relevant constraints are. However, the collection of constraints that forge an enterprise system is generally poorly defined. That is to say, the knowledge of what constraints exists and how those constraints interact is at best incomplete, disjoint, distributed, and often completely unknown. The IDEF9 Business Constraint Discovery method described in this report was designed to assist in the discovery and analysis of constraints in a business system. Once these constraints have been cataloged they can be systematically examined and, if necessary, tuned or replaced to improve the performance of the system.

Internet-based communications can provide good situational awareness for countries where public data collection is inadequate, unreliable or missing. The key challenge is to sift through this vast amount of unstructured text to identify relevant reports and to extract disease related information into a structured format suitable for analysis. In this work, Natural Language Processing (NLP) techniques are used on data from news feeds, websites, and medical publications to extract key biological event data. We developed the Threat Assessment Dashboard (BioTHAD™) in order to improve detection and monitoring of biological events. We demonstrate that disease outbreak incidence and timing can be effectively extracted from open news sources using NLP. The BioTHAD™ application could serve as a model for tracking not only infectious, but chronic diseases ...

This method is currently in beta test. Ongoing efforts in the formulation of formal semantics models for descriptions captured in the outlined form and in the actual application of this method can be expected to cause an evolution in the method language. A language is described for the representation of process and object state centered system description. IDEF3 is a scenario driven process flow modeling methodology created specifically for these types of descriptive activities.

However, the schedule of major events in ship production is collectively influenced by the actual shop-level, short-interval production schedules, which depend on resource and material availability and also on the due dates and priorities of the workloads. This necessitates development of robust, resource-constrained, shop-level scheduling systems that can support higher-level schedules in ship production. WorkShip (Knowledge Based Systems, Inc., College Station, TX) is a software tool for scheduling workload over short, regular intervals in workshops of a shipyard. It is driven by a powerful scheduling engine that is based on a generic model of resource-constrained job-shop scheduling and an efficient scheduling technique. Similar scheduling systems are being developed in other shops so that all systems can be used in tandem to support higher-...
