Completely synchronous manufacturing for automotive assembly — some lessons learned

The concepts of synchronous manufacturing look deceptively simple on paper. It appears obvious on the surface that when manufacturing operations are dependent upon one another, then the slowest operation will determine the pace of the combined operations.

Theory is one thing. Learning to really get a complex manufacturing and assembly system to work smoothly takes real patience.

One of the teaching tools was computer simulation with animation to demonstrate the concepts of synchronous manufacturing.

This paper focuses on 3 models developed using this simulation/animation tool.

Animation - a new dimension in computer simulation of automotive assembly processes

American automotive companies are moving toward increased use of JIT (i.e., Just-In-Time), SPD (i.e., Sequenced Parts Delivery), and ILVS (i.e., In-line Vehicle Sequencing) in order to produce quality vehicles at reduced cost.

Maintaining vehicles in the proper sequence leads to calculations which are functions of plant conditions (e.g., job rate, out-of--sequence conditions, etc.).

The recent advances of color animation tools to supplement the analytical simulation languages have made the understanding of these operations easier to grasp. This paper addresses the use of animation for presentation of ILVS alternatives.

The paper is separated into four sections. The first section presents ILVS concepts. This is followed by a discussion of how vehicles get out of sequence and of re-sequencing procedures. Then methods for sizing re-sequencers are described. The final section focuses on the use of animation for presenting ILVS.

Coordinated decision making in distributed applications

This paper describes how it is possible to use today's existing stateless PDPs such as the XACML PDP, to provide coordinated access control decision making throughout a distributed application. This is achieved by utilising an external database service to store the retained ADI that is needed by the PDPs. In this way the decision making can be coordinated and controlled throughout time and space. The retained ADI is modelled as coordination attributes of a coordination object, and coordination PIPs linked to each PDP access the coordination database service to retrieve the current values of the coordination attributes prior to the access control decision being made. Obligations in the access control policy define how the coordination attributes should be updated when the user is granted access to a resource. Three different modes of enforcing obligations are defined by a Chronicle directive, namely Chronicle = Before, Chronicle = After and Chronicle = With. The paper describes how the coordinated decision making has been implemented in Globus Toolkit v4, by developing a Coordinated PDP that incorporates a coordination PIP, an Obligations Service that implements the Chronicle = Before mode of operation, and a stateless PDP that makes the access control decisions; and an external coordination database grid service that has its own security controls to ensure that only Coordinated PDPs can access it. The paper concludes by discussing the implementation and indicating how the Chronicle = After and Chronicle = With modes of operation might also be supported in GT4.     

Comparison of two simulation/animation tools for synchronous manufacturing

This paper describes the use of two animation tools, namely CINEMA and PROOF, for simulation for the purpose of teaching synchronous manufacturing concepts.

This paper does not address the question of execution speed or comparison of results. The authors were really only concerned with the comparison of concurrent and post-processed animators.     

浅析如何打造国产动漫品牌

TWIXT: A 3D animation system

This paper describes a visually interactive 3D computer animation system. Animation is controlled by lists of events stored in tracks. Tracks are interpolated by functions that have an arbitrary degree of knowledge about how to control display parameters. The system provides real time wireframe playback so the animator can see what the animation looks like and is both input and output device independent.     

Use of simulation in the analysis of shop floor operations

The use of computers in actual system applications is increasing with the availability of intelligent terminals on the shop floor. These terminals can be used by management as tools in the decision making process of planning shop floor operation. This paper discusses a pilot simulation study in the use of conventional Fortran-based simulation programs by shop floor management to:

1. 1. Participate in the evaluation of proposed FMS systems,

2. 2. Assess the impact of FMS acquisition on existing facilities,

3. 3. Assist in the identification of operational alternatives in “bottle neck” situations.

The pilot study employs a batch-oriented MRP system to provide daily updates of outstanding production center loadings on a monthly planning horizon. Two intelligent terminals are used to access a mini computer facility that executes the simulation models. The terminals have AT-compatible capabilities and are also used as data acquisition devices that support the numerically controlled operations within each work center.

The simulation models represent the 13 work centers of the firm and provide information about the average utilization of each work center, the number of parts in each queue and the average delay of parts in the queues. Future extensions of the models are planned to utilize the terminals' graphic animation capabilities to display the flow of production orders through the manufacturing facility.

Solid spaces and inverse particle systems for controlling the animation of gases and fluids

This paper describes a new system for controlling the animation of gases, liquids, and volume density functions. This system is extremely powerful and flexible. It allows for the control of animation effects ranging from physically based motion of gases to the choreographed motion of gases. These techniques make extensive use of three-dimensional tables, including both flow vectors and motion functions for controlling gas animation. This new system uses aninverse particle system, where each point in three-dimensional screen space (image space discretized to pixel locations) is moved through a gas space to determine which portion of the gas occupies the current location in screen space.     

Vector Fields: an Interactive Tool for Animation, Modeling and Simulation with Physically Based 3D Particle Systems and Soft Objects

The techniques implemented in the system provide the user with new flexibility in animation, modeling and simulation. This paper describes bounded interactive vectorfields and how they can be used to manipulate particle systems and a class of soft objects. Applications to animation, modeling and simulation are also presented.

Knowledge acquisition from questionnaire data using simulated breeding and inductive learning methods

Marketing decision making tasks require the acquisition of efficient decision rules from noisy questionnaire data. Unlike popular learning-from-example methods, in such tasks, we must interpret the characteristics of the data without clear features of the data nor pre-determined evaluation criteria. The problem is how domain experts get simple, easy-to-understand, and accurate knowledge from noisy data.

This paper describes a novel method to acquire efficient decision rules from questionnaire data using both simulated breeding and inductive learning techniques. The basic ideas of the method are that simulated breeding is used to get the effective features from the questionnaire data and that inductive learning is used to acquire simple decision rules from the data. The simulated breeding is one of the Genetic Algorithm based techniques to subjectively or interactively evaluate the qualities of offspring generated by genetic operations.

The proposed method has been qualitatively and quantitatively validated by a case study on consumer product questionnaire data: the acquired rules are simpler than the results from the direct application of inductive learning; a domain expert admits that they are easy to understand; and they are at the same level on the accuracy compared with the other methods.

Furthermore, we address three variations of the basic interactive version of the method: (i) with semiautomated GA phases, (ii) with the relatively evaluation phase via AHP, and (iii) with an automated multiagent learning method.

The Controller Animation System

One of the ways in which computer animation can be generated is to use interactive graphics systems. In this paper we describe Controller, an animation system of this type. We concentrate on the operation of Controller and detail how an animator can plan and choreograph the motion of objects and cameras. We have intended to provide a system that gives the animator as much control as possible subject to keeping die interface simple to operate.     

Research problems in clothing simulation

Clothing simulation and animation are of great importance in computer animation. If cloth simulations could be improved to the point that they could generate realistic cloth motion in real-time, they would find uses in many aspects of daily life such as in fashion design and manufacturing. The area of cloth simulation and animation is full of technical challenges: creating more realistic results, achieving faster run-times, and developing methods capable of constructing and simulating more complex garments. This paper provides an overview of the key procedures involved in the creation of clothed characters, describes the current state-of-the-art techniques, and proposes the research problems that most require further study. Three technical aspects of cloth simulation are considered in this paper: garment construction, physically based simulation, and collision resolution.     

A Computer Model For Pinscreen Simulation: A New Animation Paradigm

Actual computer image and motion synthesis paradigms are presented in order to introduce a new computer animation paradigm that simulates the traditional pinscreen animation technique. Pinscreen is a very particular and difficult device that enables a “chiaroscuro” approach to image synthesis. The paper describes the traditional pinscreen technique, the way it is operated, results and related difficulties. An extended computer model, including colour and time extensions, to simulate the pinscreen is presented. Results achieved with vector and raster approaches are discussed. Advantages and possibilities of the method when compared with the traditional method and the problems that arise from this technique will also be explained. Finally current and future work is referenced.
