in this paper an efficient three- stage algorithm is developed for software production cost and time estimation. first stage includes a hybrid model composed of cocomo and function points methods to increase estimation accuracy. second stage encompasses paired comparisons matrix of analytical hierarchy process to determine amount of any resources consumed in each step of software production by ...

Risk management is one of the most critical and most difficult aspects of software project management. There is a vast literature documenting approaches and tools that address risk assessment and mitigation. In this paper, "hard" and "soft" classifications are introduced, that are basled on either the mathematical rigor describing the development of the model/tool or the mathematical rigor expe...

This presentation summarizes the results of experiments conducted over the past year to empirically validate extensions made in an attempt to use the COCOMO II Early Design model to accurately estimate web development effort and duration. The presentation starts by summarizing the challenges associated with estimating resources for web-based developments. Next, it describes a new sizing metric,...

Defining the project estimated cost, duration and maintenance effort early in the development life cycle is a valuable goal to be achieved for software projects. Many model structures evolved in the literature. These model structures consider modeling software effort as a function of the developed line of code (DLOC). Building such a function helps project managers to accurately allocate the av...

Reliable and accurate estimation of software has always been a matter of concern for industry and academia. Numerous estimation models have been proposed by researchers, but no model is suitable for all types of datasets and environments. Since the motive of estimation model is to minimize the gap between actual and estimated effort, the effort estimation process can be viewed as an optimizatio...

As the use of commercial-of-the-shelf (COTS) components becomes ever more prevalent in the creation of large software systems, the need for the ability to reasonably predict the true lifetime cost of using such software components grows accordingly. In using COTS components, immediate short-term gains in direct development effort & schedule are possible, but usually as a trade-off for a more co...

Today’s need for more complex, more capable systems in a short timeframe is leading more organizations towards the integration of existing systems into network-centric, knowledge-based system-of-systems (SoS). Software and system cost model tools to date have focused on the software and system development activities of a single software system, but none to date adequately estimate the integrati...
