§16§Load-Oriented Manufacturing Control is unique as it gives comprehensive and self-contained principles for the implementation of an appropriate production control technique of general applicability. It is based on the "funnel model", a new approach to scheduling and scheduling control which has an extensive monitoring and diagnosis system. Its most important system components include throughput diagrams, load-oriented order release, schedule-oriented capacity planning and control. The "funnel model" is getting increasing implementation in manufacturing companies. It is available in numerous variants and is especially significant for the job-shop and series production. Load-Oriented Manufacturing Control provides a large number of practical examples and is therefore relatively easy to understand. It offers direct implementation of this new important technique in manufacturing scheduling and control. §04§1 Introduction.- 1.1 Preface.- 1.2 Changes in the Manufacturing Environment.- 1.3 Shifting Objectives of Manufacturing Control.- 1.4 Scheduling in Practice.- 1.5 The Weak Points of Conventional Manufacturing Control.- 1.6 References.- 2 Conventional Production Scheduling and Control.- 2.1 Abstract.- 2.2 Survey.- 2.3 Lead Time Scheduling and Capacity Scheduling.- 2.4 Evaluation of Conventional Lead Time Scheduling.- 2.5 Requirements for New Methods of Production Scheduling and Control.- 2.6 References.- 3 Lead Time - A Key Term in Manufacturing Control.- 3.1 Abstract.- 3.2 Introduction.- 3.3 Lead Time Components.- 3.4 Simple and Weighted Mean Lead Time at a Work Center.- 3.5 Order Lead Times.- 3.6 Statistical Evaluation of Work Center Lead Times.- 3.7 Work Center Lead Time in the Shop Calendar.- 3.8 Uncertainty of Measurement and Accuracy of Computed Lead Time Values.- 3.9 Examples of Authentic Lead Time Measurements.- 3.10 References.- 4 The Throughput Diagram - A General, Realist §04§ic Model of the Manufacturing Process.- 4.1 Abstract.- 4.2 Historical Evolution.- 4.3 Basic Form of the Throughput Diagram.- 4.4 The Work Center Throughput Diagram and its Basic Data.- 4.5 Order Throughput Diagram.- 4.6 References.- 5 Analysis, Monitoring, and Diagnosis of the Manufacturing Flow.- 5.1 Abstract.- 5.2 Manufacturing Flow Monitoring.- 5.3 Manufacturing Flow Analysis.- 5.4 A Continuous Monitoring System for Manufacturing Flow.- 5.5 Diagnosis of the Manufacturing Flow in the Throughput Diagram.- 5.6 Use of Graphics for the Representation of Throughput Diagrams and Key Data.- 5.7 Implications for Manufacturing Control.- 5.8 References.- 6 Load-Oriented Order Release.- 6.1 Abstract.- 6.2 Fundamental Relationships.- 6.3 Procedure.- 6.4 Conversion of the Orders to be Loaded.- 6.5Sample Demonstration of the Release Process.- 6.6 How to Choose the Load Limit and Loading Percentage Values.- 6.7 Interlinking Order Control with Manufacturing Control.- 6.8 Effects of the Load Lim §04§it and Time Limit Parameters in Simulation and in Practice.- 6.9 Controller Analogy of Load-Oriented Order Release.- 6.10 Priority Rules and Order Sequencing in Load-Oriented Order Release.- 6.11 References.- 7 Schedule-Oriented Capacity Planning and Control.- 7.1 Abstract.- 7.2 The Problem and the Method.- 7.3 Defining the Load Centers.- 7.4 Schedule-Oriented Capacity Planning Procedure.- 7.5 References.- 8 Implementation of Load-Oriented Manufacturing Control.- 8.1 Abstract.- 8.2 Prerequisites.- 8.3 Program Modules of Load-Oriented Manufacturing Control.- 8.4 System-to-User Interfaces and Hardware Configuration.- 8.5 Implementation Strategies.- 8.6 Load-Oriented Manufacturing Control in Automated Production Sites.- 8.7 Effects of Load-Oriented Manufacturing Control.- 8.8 References.- 9 Comparison of Load-Oriented Manufacturing Control with Other Methods.- 9.1 Abstract.- 9.2 Overview.- 9.3 The Kanban Principle.- 9.4 The Job-Progress Number System.- 9.5 Finite Control with a Graph §04§ic Control Unit (Electronic Leitstand).- 9.6 Queueing Models.- 9.7 The OPT System.- 9.8 References.- 10 Summary.- Appendix A.- Appendix B.
