Fuzzy Logic Based N Version Programming For Improving Software Fault Tolerance

Therefore all classes of design (architectural, procedural and data design) become more complex. Predictability of a real time operating system puts performance at stake. However in Chimera high performance features make it different from other RTOSs.

The reliability of a system can be improved through the introduction of redundancy in the system. Some of the examples of redundancy in the operation are as below:

MPI: The fault-tolerance mechanism in MPI depends either on handling failure in the application itself or implementing regular checkpoint files.

We implement XXX as a framework with both single core and multi-core versions in an objective-oriented language. A topology can be built by declaring the connections

Deliberations on susceptibilities connected to obsolete Operating systems should also be conducted. The system should adopt sophisticated technology that is reliable and proficient.

Information will only have value if customers can access it at the right times. Availability can be affected by system errors, and malicious attacks as well as infrastructure problems. Availability is ensured by maintaining hardware as well as repairing hardware immediately when need arise. A correct functioning operating system should also be maintained in the environment free of software conflicts. Adequate communication bandwidth should also be addressed as well as preventing bottlenecks from occurrence.

As demands keep on changing and new technologies arrive, the knowledge of vast numbers of platforms and programming languages is also required. With adequate knowledge I will be able to give new ideas on which programming platform and programming language to use so as to provide improved IT systems and solutions.

A high level of interconnectedness between system components, reliance on indirect information sources, an unpredictable environment, or incomprehensibility of a system to its operators indicates complexity within a system (Perrow, 1999). Since systems are designed, run and built by humans, they cannot be perfect. Every part of the system is subject to failure; the design can be faulty, as can the equipment, the procedures, the operators, the supplies, and the environment. Since nothing is perfect, humans build in safeguards, such as redundancies, buffers, and alarms that tell operators to take corrective action. But occasionally two or more failures can interact in ways that could not be anticipated. These unexpected interactions of failures can defeat the safeguards, and if the system is also “tightly coupled” thus allowing failures to cascade, it can bring down a part or all of system. The vulnerability to unexpected interactions that defeat safety systems is an inherent part of highly complex systems; they cannot avoid this (Perrow, 1984).

Do you think what happens to the ring should depend on the reason why and who called the engagement off? Some states use the fault-based method, meaning if the person who gave the ring broke the engagements the receiver would keep the ring and vice versa if the person who received the ring called off the wedding then the ring would go back to the giver ("What Happens to the Engagement Ring in a Broken Engagement? - FindLaw," n.d.). The trend is now moving for the court systems to go with the no-fault approach by not getting involved because it’s a private matter and regardless of the situation the ring is always given back to the giver ("What Happens to the Engagement Ring in a Broken Engagement? - FindLaw,"

L.A. Zadeh, Fuzzy Sets [33] In 1965 the concept of fuzzy logic was first introduced by the Professor Lotfi A. Zadeh in the University of California, Berkeley [33]. Fuzzy logic is a powerful design system for implementing the artificial intelligence in the controller which provides simple and intuitive method for software engineers to implement logic in complex systems. This concept had been given in one amongst his research papers under the name Fuzzy logic or Fuzzy sets.

The company's failures are a result of cutbacks on both business and consumer levels. With decreasing travel, increasing fuel costs, rising energy expense, an abundance of new hotels entering the market, and over $1 billion in debt, Innkeepers USA was forced to file bankruptcy (McCarty & Kary, 2010).

Now a day’s Information Technology plays an important role in every field whether it is in big Multinational companies, or in Hospital or in school, colleges, bank etc. It is having a wide range. Every field is now a system oriented where each and every person should have knowledge of basic computer. Information technologies also important to beat the competition in various industries. In our survey report we are going to survey and test the reliability of hardware, networks and software in information technology field. Information technology is a combination of Hardware, software and Networks. It is an combining of technology, users and

Though many people interchange system engineering models and software engineering life cycle models, they are defined as two different approaches to software development. System engineering is the technical and technical management process that results in delivered products and systems that exhibit the best balance of cost and performance. As the program progresses from one phase to the next one, so does the system engineering process. It deals with the overall management of engineering project during their life cycle. Its main focus is knowing what the clients and end users wants and needs are satisfied and developing just that all the way through the system’s entire life cycle. Whereas, on the other hand, software engineering focuses on the quality of the product or system, how cost effective it is, is it done within the time-constraints given, whether it is easy to maintain and enhance, and does it work as the requirements defined. Its main focus is on delivering a product that meets the requirement specifications. There are so many models to choose from, as it all depends on what the project needs and entails. Depending on the requirements, allows for the choice of what mode to use.

Technical knowledge of computer hardware and system software is most important for performing architectural design activities. Selecting hardware and network components requires detailed knowledge of their capabilities and limitations. When multiple hardware and network components are integrated into a single system, the designer must evaluate their compatibility. Hardware, network, and overall performance requirements affect the choice of system software. The designer must also consider the compatibility of new hardware, network components, and system software with existing information systems and computing infrastructure.
