Director Using the ALPS Process Plan Model

There is a need in the industrial manufacturing community for a general-purpose model to represent hierarchical process plans with the power to express concepts such as parallelism, alternatives and synchronization. ALPS (A Language for Process Specification) is an experimental model for such a language under development at the National Institute of Standards and Technology (NIST). This paper presents a series of specific examples to demonstrate the intended usage of ALPS. In addition, the ALPS model itself has evolved to version 5. This paper presents ALPS, version 5, and discusses its differences from earlier versions.
