Variability reduction through operations reversal
Article Abstract:
Reversing processes in a manufacturing plant has been seen to be an appropriate method for reengineering a manufacturing process or supply chain through the minimization of product variability. There several situations where operations reversal is appropriate. These are when the resulting starting stage has more probable choices, the option probabilities are almost the same for both features provided by the two stages but the number of choices in the first stage is less than the next one, the first stage requires a longer process time than the next one if the features added in the two stages are equal, the features added in the first stage is less than the next one assuming that leadtimes are the same, and the first stage has a longer leadtime but the value-added per process time is less than or equal to the value-added for the next stage.

Economic models for vendor evaluation with quality cost analysis
Article Abstract:
The cost of vendor quality is usually analyzed before selecting vendors to ensure a successful vendor-vendee relationship. Tang's (1988) model addresses the link between the vendor's input quality and the vendee's quality control system. The weakness of his analysis is that it does not consider the imperfections of the internal manufacturing process of the manufacturing enterprise, which has been found to have an impact on the assessment of the quality costs of the incoming materials. To fill the gap in vendor evaluation research, a study was conducted to investigate the relationship between the vendor's quality cost, the vendor's input quality and the imperfections of the manufacturing process. The properties of the resulting quality cost model are examined and managerial implications are derived.

Economic design of control charts with different control limits for different assignable causes
Article Abstract:
Research on the statistical control of manufacturing systems which feature an involved process that produces an output with a measurable quality characteristic is described. When different assignable causes exist which lead to different out-of-control states of the process the use of multiple control limits and multiple corresponding levels of response for processes is an effective way for statistical process control. An exact mathematical model is explained, figuring the expected cost per time unit.
