Accurate software development cost estimation is important for effective project management such as budgeting, project planning and control. So far, no model has proved to be successful at effectively and consistently predicting software development cost. A novel neuro-fuzzy Constructive Cost Model (COCOMO) is proposed for software cost estimation. This(More)
This paper describes Work Domain Analysis (WDA) applied to the domain of automated midair collision detection and avoidance as a first step in the design of improved ecological interfaces for automated traffic alerting displays. Three abstraction hierarchies (AH) modelling the aircraft, collision environment, and a traffic alerting system are presented, and(More)
— Software cost estimation is a crucial element in project management. Failing to use a proper cost estimation method might lead to project failures. According to the Standish Chaos Report, 65% of software projects are delivered over budget or after the delivery deadline. Conducting software cost estimation in the early stages of the software life cycle is(More)
In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository.

— Software effort estimation is one of the most important tasks in software engineering. Software developers conduct software estimation in the early stages of the software life cycle to derive the required cost and schedule for a project. In the requirements stage, where most software estimation is conducted, the available information is usually imprecise(More)
It is very important to conduct software estimation in the early stages of the software life cycle, because it helps managers bid on projects and allocate resources efficiently. This paper presents a novel regression model to estimate the software effort based on the use case point size metric. The use case point model takes use case diagrams as input and(More)
-Accurate software development effort estimation is a critical part of software projects. Effective development of software is based on accurate effort estimation. Although many techniques and algorithmic models have been developed and implemented by practitioners, accurate software development effort prediction is still a challenging endeavor in the field(More)
The need to update the calibration of Function Point (FP) complexity weights is discussed, whose aims are to fit specific software application, to reflect software industry trend, and to improve cost estimation. Neuro-Fuzzy is a technique that incorporates the learning ability from neural network and the ability to capture human knowledge from fuzzy logic.(More)
