Reliability in the utility computing era: Towards reliable Fog computing

This paper considers current paradigms in computing and outlines the most important aspects concerning their reliability. The Fog computing paradigm as a non-trivial extension of the Cloud is considered and the reliability of the networks of smart devices are discussed. Combining the reliability requirements of grid and cloud paradigms with the reliability requirements of networks of sensor and actuators it follows that designing a reliable Fog computing platform is feasible.

ON USING SOFT COMPUTING TECHNIQUES IN SOFTWARE RELIABILITY ENGINEERING

Previous investigations have shown the importance of evaluating computer performances and predicting the system reliability. This paper considers soft computing techniques in order to be used for software fault diagnosis, reliability optimization and for time series prediction during the software reliability analysis. It is shown that the study of the data collections during a software project development can be done within a soft computing framework.

Improving Software Reliability Forecasting

This work investigates some methods for software reliability forecasting. A supermodel is presented as a suited tool for prediction of reliability in software project development. Also, times series forecasting for cumulative interfailure time is proposed and illustrated.

Neutrosophic Logic Applied to Decision Making

Decision making addresses the usage of various methods to select “the best”, in some way, alternative strategy (from many available) when a problem is given for solving. The authors propose the usage of neutrosophic way of thinking, called also Smarandache’s logic, to select a model by experts when degrees of trustability, ultrastability (falsehood), and indeterminacy are used to decide. The procedures deal with multi-attribute neutrosophic decision making and a case study on e-learning software objects is presented.

A Decision Support System for Pollution Control in Cement Plants

The control of the pollution dynamics supposes the control of the whole pollution chain, starting from production planning and ending with pollution parameter measurements. This paper describes a software system that will scan the pollution activity specific for cement plants and will propose logistical solutions with the purpose of pollution control so that the costs of pollution reduction are minimized.

Total Quality for Software Engineering Management

Strategies to obtain software quality are examined. The basic approaches in software quality assurance are covered; ISO 9000 and CMM standards being considered. The practice of software engineering is illustrated by ESA standards and modern software development techniques. Other methodologies are: software reliability engineering, software engineering economics, and software management. Putting them together, and using the adapted Deming’s philosophy, the software organization will implement the total quality management paradigm.

On The convergence of the quasi-gauss-newton methods for solving nonlinear systems

The Quasi-Gauss-Newton methods for solving general nonlinear systems of equations are described and a convergence theorem for iterative methods in this class is proved. Computational aspects are also discussed.

A Monte Carlo approach for controlled search

We outline a new Monte Carlo approach for solving minimization problems. A splitting procedure, which is a controlled random search with domain reduction, is presented. Algorithms and numerical results are also included.

Software reliability in the fog computing

Fog computing is a new paradigm using both Cloud computing developments and Internet of Things devices. This paper reviews the existing models, architectures and practices in Fog computing targeting the fog systems reliability and dependability. An integratory approach of three components of the system reliability is considered: the nodes reliability, the network reliability, and the software reliability. OpenFog Reference Architecture, and AJIA and BDSC schemes were considered as principal vectors in fog reliability increasing.
