MATHEMATICAL MODEL FOR CALCULATING RELIABILITY INDICES OF SCALABLE COMPUTER SYSTEMS WITH SWITCHING TIME

A Mathematical Model for City Logistics Distribution Network Design with the Aim of Minimizing Response Time

Recently, urbanization has been expanded rapidly in the world and a number of metropolitan areas have been appeared with a population of more than 10 million people. Because of dense population in metropolitan and consequently increasing the delivery of goods and services, there has been a lot of problems including traffic congestion, air pollution, accidents and high energy consumption. This m...

Secure Computer Systems: A Mathematical Model

This paper presents a set of rules of operation which guarantee that a computer system can remain secure while exhibiting certain desired external characteristics. The rules are easily transformable into algorithms suitable for implementation on a digital computer. iii PREFACE In our introductory paper on secure computer systems (MTR-2547, Vol. I) we introduced a framework for mathematical mode...

A fuzzy reliability model for series-parallel systems

Fuzzy set based methods have been proved to be effective in handling many types of uncertainties in different fields, including reliability engineering. This paper presents a new approach on fuzzy reliability, based on the use of beta type distribution as membership function. Considering experts' ideas and by asking operators linguistic variables, a rule base is designed to determine the level ...
