Performance and Scalability Challenges of an Revised Implementation Model of Assessment Test Generation Using Distributed Systems

The addition of the performance characteristic to an implementation is a crucial step in delivering the best results. In this matter, the current paper presents a description of a model which uses concepts related to web distribution systems in order to improve the performance and scalability of an implementation of a system that will be used in educational assessment and which generates assessment tests using genetic algorithms. The distributed systems could be used as a modality of implementing parallel operations for the genetic algorithm, such as mutation or crossover, but also for specific parts of the implementation, such as the selection process of the items within the assessment test. This paper has the aim to describe an improved model for this system, in order to be used for implementation and results.
