Testing, validation, and verification of an expert system advisor for aircraft maintenance scheduling (esaams).
Verification and validation of simulation models definitions: verification is the process of determining that a model implementation and its associated data accurately represent the developer's conceptual description and specifications.
For these reasons it is important for the software engineering expert to make sure the validation, verification and evaluation of the system are made at their best. Expert systems use computational techniques that involve making decisions, just as human experts do, but it is well known that human experts may be wrong from time to time.
Verification and validation of rule-based expert systems is a valuable reference for electrical engineers, software engineers, artificial intelligence experts, and computer scientists involved with object-oriented development, expert systems, and programming languages.

An expert system advisor for aircraft maintenance scheduling (esaams) is being implemented at the naval postgraduate school.
The use of expert systems in various disciplines proves an increase in human productivity, financial benefits and a better answer to users needs. There is a need for a development and integration environment that supports knowledge management and expert system construction, but also the debugging and verification as well.
The goal of this paper is to distinguish between verification and validation as they relate to the total expert system evaluation process.
More formally, an expert system (es) has been defined as 'a computing system capable of representing and reasoning about some knowledge-rich domain with a view to solving problems and giving advice' (jackson 1986) and 'a computer model of expert human reasoning, reaching the same conclusions the expert would reach if faced with a comparable problem' (weiss and kulikowski 1984).
Software due diligence and health checks are two services that provide unique insights into code status and quality. While based on automatisation and state-of-the-art technology, these services also need a human touch.
Expert systems (ess) have been used successfully for design, diagnosis, and monitoring in a range of industries—from computers to accounting.

Abstract and figures validation is a critical process in the whole knowledge-based system life cycle. A knowledge base incorporated into such systems has to be verified or (more generally).
And the widely varied topography in malaysia can result in severe soil loss and sediment generation.
The applicability was then assessed of each for the identified components of knowledge-based and expert systems, as well as the system as a whole. By means of a literature survey, a comprehensive set of methods was identified for the verification and validation of conventional software.
Aircraft maintenance control operates in a dynamic, high intensity environment. Maintenance work priorities are made several times daily under extremely demanding and time sensitive conditions. The person responsible for scheduling aircraft, usually the maintenance master chief, draws upon years of experience when assigning priorities for both scheduled and unscheduled maintenance.
From the software engineering aspect, there are four activities for expert system development: requirements specification, design, implementation, and testing.
