The manufacturing of complex products often involves the assembly of other products, or sub-assemblies. Furthermore, these sub-assemblies may be manufactured by different suppliers. As a result, the specification of the assembly process for the final product contains relationships between multiple supply chain components, including business entities, manufacturing processes, products, and parts. This specification, involving the coordination and arrangement of supply chain components to support final product assembly, is referred to as a supply chain configuration. A supply chain configuration tool is used to recognize and modify the relationships between these components. Users of this tool may be engineers, purchasing agents, program managers, or other personnel concerned with the configuration's dependencies. The focus of this paper is on the development of such a tool and its use from the perspective of a purchasing agent. © 1997 by ASME.

The practical deployment of distributed agent-based systems mandates that each agent behave sensibly. The paper focuses on the development of flexible, responsive, adaptive systems based on sensible agents. Sensible agents perceive, process, and respond based on an understanding of both local and system goals. Each agent is capable of (1) deliberative or reactive planning and execution of one or more domain-specific service/task, (2) maintaining and interpreting knowledge about states, events, and goals related to itself, other agents, and the environment, and (3) adapting its behavior according to its understanding of its own local goals and overall system goals. The paper addresses the above issues in the context of applied semiotics, a field that analyzes and develops the formal tools of knowledge acquisition, representation, organization, generation, enhancement, communication, and utilization. A sensible agent architecture has been developed where each agent is composed of five modules: a self-agent modeler, an external agent modeler, an action planner, an autonomy reasoner, and a conflict resolution advisor.

Object oriented analysis, modeling, and simulation of a notional air defense system

SIMULATION 1996年第1期66卷 5-21页

作者： Barcio, BT Ramaswamy, S Macfadzean, R Barber, KS The Laboratory for Intelligent Processes and Systems Department of Electrical and Computer Engineering The University of Texas at Austin Austin Texas 78712-108 USA

This paper describes the analysis, modeling, and simulation of a notional air defense system using SMOOCHES (State Machines for Object-Oriented, Concurrent, Hierarchical engineering Specifications). SMOOCHES is an object-oriented environment based on hierarchical state machines and extensions to Statecharts, specifically developed as an environment to specify, model, simulate and analyze/evaluate distributed, reactive systems. Using a high level system specification language, an object-oriented, herarchical state specification of a radar tracking system with realistic constraints is derived. A graphical statechart representation of the tracking system behavior is also derived and implemented within the SMOOCHES environment.

An experience-based assembly sequence planner for mechanical assemblies

IEEE TRANSACTIONS ON ROBOTICS AND AUTOMATION 1996年第2期12卷 252-267页

作者： Swaminathan, A Barber, KS Laboratory for Intelligent Processes and Systems Department of Electncal and Computer Engineering University of Technology Austin TX USA University of Texas at Austin Austin TX US Dept. of Electr. & Comput. Eng. Texas Univ. Austin TX USA

This paper presents an approach to the assembly sequence planning problem based on a ''plan reuse'' philosophy. Most of assembly planning research in the past has attempted to completely plan each problem from scratch, This research shows that stored cases of basic assembly configurations can be applied to a given assembly problem. It is observed that the number of such basic assembly configurations is quite small, In the first phase of planning (EVALUATOR phase), the assembly is divided into a number of constituent configurations, which are called ''loops.'' These act as subgoals in its search for solutions (RETRIEVER phase). Plans retrieved for all the subgoals are fused into a set of plans that are consistent with the constraints implied by each plan (MODIFIER and COMPOSITER phases), Application specific constraints on the assembly are explicitly handled in the final phase of planning (POSTPROCESSOR phase).

The building of a virtual environment for the construction, analysis, and design of a three dimensional virtual manufacturing prototype is discussed. An agent-based framework is used to specify the visual environment. The environment is built to be flexible enough to support research efforts in scheduling, planning, and behavior modeling. The implementation consists of a heterogeneous, distributed interactive virtual environment using the virtual environment tool, DIVE. © 1995 American Society of Mechanical Engineers (ASME).

This paper discusses an architecture designed to provide support for the development of state transition models for an object-oriented distributed environment. The state transition models can be constructed and specified hierarchically as well as derived into new classes of objects through the use of inheritance. A new concept called "exit-safe states" is introduced to assist in the specification of hierarchical state transition models. A graphical monitor to analyze the system at run time has been developed.

This paper presents an approach to the assembly sequence planning problem based on a "plan reuse" philosophy, called the Assembly Planner using Experience (APE). Assembly planning research in the past has attempted to completely plan each problem from scratch. This research shows that stored cases of basic assembly configurations can be applied to a given assembly problem. It is observed that the number of such basic assembly configurations is quite small. Constraints affecting the assembly are also explicitly handled.

A structured development approach to deriving system models that helps to better understand and represent system details is presented. Real-world systems are never completely designed by either top-down or bottom up approaches. Therefore, methods that allow the integration of these two approaches as well as provide a means for analyzing such models are very useful. First, a general purpose system architecture, a corresponding system specification language, and a broad classification of the various concurrent system activities are presented. Second, Petri net (PN) extensions to simplify system specification and modeling are provided. Third, a transformation between the high level specifications to the proposed PN extensions is provided. Finally, a PN system model using the new PN extensions is derived as an example. To facilitate the use of existing PN based analysis and simulation tools a transformation between the PN extensions used in this paper to classical PNs is also illustrated.

IEEE Conference on Decision and Control

The construction and analysis of multiple-input multiple-output (MIMO) subnets is discussed. It is shown that hierarchical time-extended Petri nets (H-EPNs) allow the development of structured MIMO subnets through the use of bottom-up Petri net synthesis techniques. The paper analyzes Petri net extensions that allow a truly hybrid approach to Petri net based systems modeling, analysis and development. The case study emphasizes the advantage of the activator arc extension in studying issues such as static priority scheduling, dynamic failure recognition, and rescheduling in manufacturing systems. The SPNP package, suitably modified to handle the H-EPN extensions, is used to analyze the properties of the derived H-EPN model.
