Flexible ABC Inventory Classification

An integrated model for solving the multiple criteria ABC inventory classification problem

In this paper, we present an integrated version of the Ng model and Zhou and Fan model [W. L. Ng,A simple classifier for multiple criteria ABC analysis, European Journal of Operation Research, 177(2007) 344-353; P. Zhou & L. Fan, A note on multi-criteria ABC inventory classification usingweighted linear optimization, European Journal of Operation Research, 182 (2007) 1488-1491]. Themodel that N...

A note on multi-criteria ABC inventory classification using weighted linear optimization

Recently, Ramanathan (R., Ramanathan, ABC inventory classification with multiple-criteria using weighted linear optimization, Computer and Operations Research, 33(3) (2006) 695-700) introduced a simple DEA-like model to classify inventory items on the basis of multiple criteria. However, the classification results produced by Ramanathan are not consistent with the domination concept encouraged ...

ABC: A New Fast Flexible Stream Cipher

ABC is a synchronous stream cipher optimized for software applications. Its key length is 128 bits. It accommodates a 128-bit initial vector. Here a version of ABC with a 128-bit key and 32-bit internal variables is presented. A new approach to the design of stream ciphers has been used which results in a cipher based upon keyand clock-dependent state transition and filter functions. More preci...
