RISStream of Variation Modeling and Analysis of Serial-Parallel Multistage Manufacturing Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a Serial-Parallel Multistage Manufacturing System (SP-MMS), identical work-stations are utilized at each stage to meet the productivity and line balance requirements. In such a system, parts ...
Using Error Equivalence Concept to Automatically Adjust Discrete Manufacturing Processes for Dimensional Variation Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Traditional statistical process control (SPC) has been widely employed for the process monitoring in discrete part manufacturing. However, SPC does not consider any adjustment preventing the process ...
Multi-Operational Machining Processes Modeling for Sequential Root Cause Identification and Measurement Reduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Variation propagation modeling has been proved to be an effective way for variation reduction and design synthesis in multi-operational manufacturing processes. However, previously developed approaches ...
Part Dimensional Error and Its Propagation Modeling in Multi-Operational Machining Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a multi-operational machining process (MMP), the final product variation is an accumulation or stack-up of variation from all machining operations. Modeling and control of the variation ...
Online Multichannel Forging Tonnage Monitoring and Fault Pattern Discrimination Using Principal Curve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the late response to process condition changes, forging processes are normally exposed to a large number of defective products. To achieve online process monitoring, multichannel tonnage ...
Deriving Operating Rules of Pumped Water Storage Using Multiobjective Optimization: Case Study of the Han to Wei Interbasin Water Transfer Project, China
Publisher: American Society of Civil Engineers
Abstract: Pumped water storage (PWS) is an advanced component of interbasin water transfer (IBWT) projects that plays a critical role in addressing streamflow variability. However, improper operating rules result in a large amount ...
