A microworld model for multiagent computer-aided process planning .

摘要

This Thesis proposes and investigates a novel framework for the study of multiagent solutions for computer-aided process planning (CAPP) in manufacturing systems. The framework is based on a domain-specific microworld model of CAPP, called the CAPP World. The proposed CAPP World is characterized by a product class, a model of a manufacturing cell, and appropriate adaptation and simplification of CAPP modeling concepts from the literature. These abstractions lead to a collection of specific actions that jointly construct a process plan in CAPP World. The analysis shows that the model meets its design objectives: it is simple, representative of properties and difficulties in real-world CAPP, and suitable for formulation and investigation of multiagent solutions for CAPP, as demonstrated through construction of concrete scenarios. The scenarios address topics such as: agent encapsulation, communication, cooperation, and coordination among team members. The Thesis also identifies some topics for future research.
