Abstract
An increasing number of requirements are being placed on plan
representations as we forge ahead toward future implementations of
artificial intelligence planning systems. During a plan's life many
different tasks may be performed on it. Plan representations are
needed to meet the requirements of a range of systems responsible
for these specific tasks, with possibly conflicting desiderata.
Existing work has investigated shared representations of plans which
can facilitate the integration of work throughout a plan's
life-cycle. These shared representations should be rich enough to
address many of the intended uses. This paper presents a set of
requirements derived from a range of sources which can be used to
steer the future extension or development of rich, shared plan
representations.
Abstract
This paper is a summary of analysis work completed during phase 2 of
the National Institute of Standards and Technology's (NIST) Process
Specification Language (PSL) project. A set of requirements for this
language was produced in phase 1. These requirements were divided
into separate categories. The main categories of interest for this
analysis are the core and outer core requirements. Each set was then
further partitioned into either representational or functional
requirements. In phase 2, existing candidate process
representations were proposed which were believed to satisfy much of
the representational and functional needs. Most of the particular
set of candidates reviewed are those representations generated by
participants in the DARPA/Rome Laboratory Planning Initiative
(ARPI), or representations in which participants in the initiative
played a part. The results of the analyses of a number of the
candidate representations with respect to the requirements are
reviewed here.
Abstract
The goal of the NIST Process
Specification Language (PSL) project is to investigate and arrive at a
neutral, unifying representation of process information to enable
sharing of process data aomng manufacturing, engineering and business
applications. This paper focuses on the second phase of the project,
the analysis of existing process representations to determine how well
existing process representation methodologies support the requirements
for specifying processes found in Phase One. This analysis will
provide an objective basis from which to develop a comprehensive
language and will promote the leveraging of existing work.
