ABSTRACT:
A system for estimating the effort necessary to complete a project comprises a rule-based expert system including groups of related estimation rules (rule groups) and a question table, a neural network, the neurodes of which represent groups of the detailed tasks (task groups), a rule indirection module for coupling the outputs of the rule-based expert system to selected neurodes, and an inference engine for implementing the rules of the expert system. The expert system, neural network, and rule indirection module are organized as an advisor module, which communicates information between an advisor interface and the question table. Each rule group represents a quantifiable feature of the specific client/server implementation, such as its size or fault tolerance requirements. The inference engine applies the rule groups to user provided data, and each rule group generates an effort factor (EF) that provides a measure of the associated feature's potential impact on the task groups. The rule indirection module couples each effort factor to selected task group neurodes according to influence factors (IF), which represent the correlation between the feature characterized by the rule group and the selected task groups. The influence factors are initially estimated as part of the expert system but may be further optimized by training the estimator using actual measured efforts and efforts estimated by the present invention.
