Adaptive SPC monitoring scheme for DOE-based APC

Automatic process control （APC） based on design of experiment （DOE） is a cost-efficient approach for variation reduction. The process changes both in mean and variance owing to online parameter adjustment make it hard to apply traditional SPC charts in such DOE-based APC applied process. An adaptive SPC scheme is developed, which can better track the process transitions and achieve the possible SPC run cost reduction when the process is stable. The control law of SPC parameters is designed by fully utilizing the estimation properties of the process model instead of traditionally using the data collected from the production line. An example is provided to illustrate the proposed adaptive SPC design approach.     

The Design of Behavior Management Institution Based on Special Symbols and Measure Optimizing-Taking the Design of the Institution of Controlling the Pollution Behavior of Enterprises as an Example

Taking the institution design of controlling the pollution behavior of enterprises as an example, the symbol system specialized for the design and analysis of behavior management institution is put forward, which predigests the institution design greatly and make the process of institution design much like the engineering design.

A Systemic Evaluation of the State of Affairs Following the Negative Outcome of the Referendum in Cyprus Using the Structured Dialogic Design Process

This paper reports the results of the first of a series of co-laboratories organized by Cypriot peace pioneers 30 months after the negative outcome of the referendum concerning UN General Secretary’s plan for reunification of the island. The purpose of this co-laboratory was to support a diverse group of disengaged and disappointed peace pioneers and activists representing Turkish and Greek communities of Cyprus develop a shared understanding of factors contributing to the perceived widening of the gap between the two divided communities in Cyprus. The co-laboratory was organized using the structured dialogic design process (SDDP) approach within the context of a rich web-based communication environment. The root causes contributing to the widening of the gap are discussed and are also compared with those identified during a similar co-laboratory employing the Interactive Management methodology 12 years earlier.
