INTRODUCTION
In any industry today inventory optimization is such a vital function. Excess and Shortage of inventory
in all levels of the supply chain can affect the availability of products and/or services to consumers. Several
monitoring systems and processes can be employed to check inventory imbalances to minimize the supply and
demand dynamics. To simply these monitoring systems and process items/materials/products are classified into
different groups [1]. Also it is easier to monitor and control vast systems through the Concept of Importance and
Exception (CIE).
