Process Imaging
Published in David M. Scott, Industrial Process Sensors, 2018
Measurement and control technology can simplify the operation of process equipment, improve product quality and asset productivity, and minimize waste by increasing first-pass yield. Thus, there are real economic incentives for improving the control of these processes. In the past, the feedback used for industrial control systems was based on scalar quantities such as temperature and pressure, which were measured at single points in the process. Due to the increasingly stringent demands on the quality of products produced by increasingly complex systems, more sophisticated measurements are needed to control manufacturing processes. Two-dimensional (2D) and sometimes three-dimensional (3D) information is needed to optimize processes such as casting of polymer film and mixing chemical components. Process imaging techniques provide this higher dimensionality.
Multicompany Collaboration to Reduce Costs—Who, What, and How

This category is more intense two-way collaboration. This collaboration is more likely to go on personally, by phone or face to face, rather than through message exchanges. An example is an effort in manufacturing to increase process yields. Small increases in first-pass yield bring outsized benefits in capacity and profit. Often, this requires collaboration between a supplier and its OEM customer. The collaboration should address root causes for yield losses, including too-tight specifications from the OEM. These can be caused by variations in processes such as those that are targets of Six Sigma initiatives described in Chapter 17.

In the improve phase, the team set up experiments to determine which factors (with several possible versions of each factor) had the greatest impact on the defect. The results of several experiments led to process changes that the team implemented. A pilot study of these changes indicated that the first pass yield was near 90 percent, a significant improvement over the original mid-40 percent first pass yield at the start of the project.

Furthermore, the hyper objects can also provide feedback data to the management system, supporting the real-time information visibility and traceability of the AW4.0 systems. As shown in Figure 9, the production plan module shows the real-time work progress statistics and compares that with the production plan, which would help to adjust and optimise the production plan timely. The employee status module statistics the health status, work capacity, and skill level can be used for work assignments and employee management. The real-time operation instruction module can provide personalised work guidance according to the real-time progress of the individual operator. The equipment condition module supports real-time equipment status monitoring for predictive maintenance and OEE (overall equipment effectiveness) improvement. The materials condition module can monitor the materials usage and stock level on a real-time basis to help work assignment and predictive replenishment. Finally, all in-situ inspection information is linked to the FPY (first pass yield), which is helpful for quality management and continuous improvement.
Universal-deterministic and probabilistic hypotheses in operations management research: a discussion paper
Published in Production Planning & Control, 2018
Garvan Whelan, Roberto Sarmiento, Jan Sprenger
Based on case study research, Antony, Gijo, and Childe (2012) explained how the implementation of a Six Sigma system in a precision automotive manufacturing setting resulted in clearly specified improvements in quality tolerance levels, first pass yield rates, and in profitability. This is an example of a case study article that provides clear precise information on the factors that explain the reported improvements, the basis of measurement, and the specified causal relations between the variables. We suggest that, from these findings, it is possible to formulate a universal-deterministic hypothesis such as:
