The matrix exponential spatial specification (MESS) is an alternative to the autoregressive-type (SAR-type) specifications with several attractive properties. dependence in MESS-type models formulated through a term, and estimation of these may require computation terms many times procedure. In literature, it well documented that can pose challenges reliability, stability, accuracy, efficiency....

This paper presents the analysis of a continuous review perishable inventory system wherein the life time of each item follows an exponential distribution. The operating policy is (s,S) policy where the ordered items are received after a random time which follows exponential distribution. Primary arrival follows Poisson distribution and they may turnout to be posit...

In this paper we provide properties of moments of matrix exponential distributions and joint moments of matrix exponential processes. Based on the provided properties, an algorithm is presented to compute any finite dimensional moments of these processes based on a set of required (low order) moments. This algorithm does not require the computation of any representation of the given process. We...
