SPC research—Current trends

Effective implementation of SPC

Statistical process control (SPC) is an approach to process control that has been widely used in any industrial or non-industrial fields. SPC is based on so called Shewhart ́s conception of the process variability. This conception distinguishes variability caused by obviously effected common causes (process is considered to be statistically stable) from variability caused by abnormal assignable ...

Turbo-SPC codes

—This letter is concerned with a family of modified turbo-type codes, referred to as turbo-SPC (single parity check) codes. A technique based on the SPC code is introduced to replace puncturing for rate adjustment. A noticeable feature of the proposed scheme is the significantly reduced decoding complexity compared with the standard punctured turbo code. The cost reduction factor becomes more n...

Notes on SPC: A Parallel Programming Model

In automatic, retargetable compilation low-cost, analytic cost estimation techniques are crucial in order to e ciently steer the optimization process. Programming models aimed at optimum expressiveness of parallelism, however, are not amenable to static cost estimation. We present a new coordination model, called SPC, that imposes speci c restrictions in the synchronization structures that can ...

Using SPC in conjunction with APC

Applying Spc to the Personal Software Process

In recent years, a growing number of software organizations have begun to focus on applying the concepts of statistical process control (SPC) to the software process, usually as part of an improvement program based on the Software CMM. There are a number of technical challenges to the successful use of these statistical techniques, primarily centered on the issues associated with high variatio...
