  Two excellent papers have recently appeared in _Communications
  Of The ACM_ on the topic of Entity-Life Modeling, a design technique 
  for concurrent software systems.

  The first article, "An Entity-Life Modeling Approach to the 
  Design of Concurrent Software", illustrates the design of a
  elevator control system using entity-life modeling, and compares
  it to the JSD (Jackson Structured Development) approach.  It appears
  in the March 1989 issue (Volume 32, Number 3), pages 330-343.

  The second article, "Entity-Life Modeling and Structured Analysis
  in Real-Time Software Design - A Comparison", compares the approach
  of entity-life modeling with the approach of structured analysis.
  It appears in the December 1989 issue (Volume 32, Number 12), pages 
  1458-1466. 

  The author is Bo Sanden, of the Center for Software Systems Engineering
  at George Mason University.  I strongly recommend these articles to anyone
  who is interested in the topic of designing concurrent software systems.
