Description

Computer-Aided Rate Modeling and Simulation (CARMS) is an integrated Markov modeling and simulation tool designed to solve a wide range of time-dependent, prediction-oriented problems. The features include a state diagram-based CAD environment for model setup, a spreadsheet-like interface for data entry, an expert system link for automatic model construction, and an interactive graphics interface for displaying simulation results.

Primary Applications

Reliability analysis, operations research, fault-tolerant systems, engineering design, and scientific or statistical modeling using Markov analysis.

Benefits

By using CARMS for analysis, complex design cycles can be shortened, simplified, and better understood and documented.

In particular, CARMS excels as a general purpose tool suitable for reliability, maintainability, and availability (RMA) prediction. It can be employed to solve a variety of RMA and other mathematically related problems.

A combination of text- and graphics-based data input makes the program ideal for problems in which a product, operations, system, or engineering design is at the conceptual phase. In this phase, flexibility, ease of use, and speed are prime requirements i n determining the ideal course of action and probing the "what if?" scenarios.

Unlike the traditional methods of computer-based prediction, CARMS features an interactive environment that allows the user to quickly change data values and graphical representations of a given system. Menu-driven commands and help screens are also available.

Listed below are several features of CARMS:

• Spreadsheet-like data input screen.
• Vector-based graphics for constructing transition diagrams.
• Expert-system front end which automates model construction.
• Symbolic algebra for simplifying expressions.
• Graphical display of results as a function of time.
• Generation of graphics and reports to printer, clipboard, or file.
• Choice of numerical routines for solving a range of problems.

Typical CARMS Uses

• Reliability prediction
• Fault-tolerant system design
• State diagram construction
• Markov analysis
• Markov chain fault modeling
• Maintainability and availability predictions
• Waiting line and servicing (queueing) modeling
• Inventory system analysis
• Probability evaluation
