Article Abstract:
The establishment of new chemical-process industries facilities in the developing world, particularly South America, the Middle East, Africa and parts of Asia, necessitates coping with conditions and ground rules that are different from those of the industrialized world. Materials management entails a material control system that incorporates emerging technology, utilizes leadtime and required-on-site data and forestall problems.

Article Abstract:
Exponential weighting is a statistical method that can be used to monitor continuous processes. The procedure can be integrated into a programmable logic controller for automatec operations. The method can be defined in functional terms as exponentially weighted moving average (EWMA) or as exponentially weighted moving standard deviation (EWMSD). Both EWMA and EWMSD are useful tools for evaluating output and process parameters.
