Excel Software Ships WinA&D 5.0 System Models, Time Simulation & Dynamic Charts

System Models, Time Simulation & Dynamic Charts

Excel Software started shipping WinA&D 5.0, an engineering tool for system analysis, requirements management, software models, code generation, reengineering and scriptable project reports. The new release adds system models, simulation and dynamic charts to its suite of software engineering capabilities. Other enhancements include a project scrapbook, flow, store and external entity Detail dialogs for structured analysis & design, user-interface improvements and new project reports.

We live in a world of systems driven by cause and affect. Those systems include financial, production, inventory, biological, chemical, thermodynamic and workflow. Systems can be modeled as Causal Loop Diagrams with nodes representing system variables and connecting lines representing causal effects. The changing value of one variable can cause another to increase or decrease as described by equations. Understanding how a system really works is the first step towards using, improving, automating or explaining it to others.

WinA&D presents an easy, integrated solution to model dynamic systems as Causal Loop Diagrams, parameterize the model with data and equations, run time simulations and present the system behavior with live charts, graphs and tables. Data files can provide input data to models or capture output results. The integrated Data File editor makes it easy to edit data items of type Variable, Array and List or import/export data to a spreadsheet, database or charting application as a comma or tab delimited file.

WinA&D 5.0 adds a new Project Scrapbook window. The scrapbook is a community resource that anyone on the project can concurrently view or edit. It provides a convenient placeholder for project artifacts created from any application. Typical examples include marketing specifications, graphic illustrations, project schedule, software models, tables, graphic charts of simulation results or test plans. Scrapbook items can be organized, copied, pasted, printed or double-clicked to view and edit the original document in its native application.

WinA&D windows now have mouse scroll wheel support and allow a table of contents to be dragged open or closed on all diagram windows. The built-in scripting language adds tags for math functions, scrapbook items, dynamic charts and reading and writing of variables in data files, plus new standard reports for sharing project data. Reengineering enhancements make it easier to generate meaningful models from code by clustering object-oriented classes on diagrams based on user selected relationships.

WinA&D runs on Windows 95 through XP and is available in a Standard edition at $495, Desktop edition at $1295 or Developer edition at $1995. To learn more about WinA&D’s new system modeling and simulation features, see the System Models & Simulation.pdf at www.excelsoftware.com.
