Discussions with software developers from a number of business organisations were targeted at the effect of estimation practices on the success or failure of some of the software development projects with which they had been involved. Several important estimation topics were also covered in a questionnaire. Our results show that for only one-third of the projects were the project managers invol...

There is an increasing interest in acquiring commercial-off-the-shelf (COTS) functionality for safety-critical applications. However, the selection of COTS products for such applications is still carried out in an ad hoc manner. This creates great difficulties for realistic cost and effort estimation, integration of the selected COTS product, and the certification of final COTS-based safetycrit...

In the software development process, effort distribution based on phase is an important but often a neglected aspect of software cost estimation. Insufficient phase effort distribution study is the primary reason of poor software effort estimation. This paper provides the results of an empirical study on phase effort distribution based on 2956 projects. The software development process is divid...

Background The Cost Action FP0905 aims to evaluate the scientific knowledge of GMT biosafety protocols coordinating the existing information generated in various European countries as basis for future EU policy and regulation for the environmental impact assessment. For spreading the information relevant to the Action, the website http://www.cost-action-fp0905.eu/has been set up, educating the ...

Development effort is an undeniable part of the project management which considerably influences the success of project. Inaccurate and unreliable estimation of effort can easily lead to the failure of project. Due to the special specifications, accurate estimation of effort in the software projects is a vital management activity that must be carefully done to avoid from the unforeseen results....

The paper aims to provide for the improvement of software estimation research through a new regression model. The study design of the paper is organized as follows. Evaluation of estimation methods based on historical data sets requires that these data sets be representative for current or future projects. For that reason the data set for software cost estimation model the International Softwar...

Expert-based estimation is the most common and preferred method to estimate the effort for software development project because it is fast, less expensive and reasonably accuracy. Expert software developers use his intuition and experience during effort estimation task. Estimation by analogy of features is also used to compare the new feature to similar in past development. This paper extends r...

For discussion only Exceedingly preliminary and incomplete Please do not cite or distribute / post on a website Robust Cost Systems Organizations employ a cost system to estimate the costs of their products and customers, even though such estimation is not an economically sufficient aggregation of the underlying production function and results in sub-optimal decisions. While there are many pres...

In this paper we suggest evaluating the importance of a website with the mean frequency of visiting the website for the Markov chain on the Internet Graph describing random surfing. We show that this mean frequency is equal to the sum of the PageRanks of all the webpages in that website (hence is referred to as PageRankSum ), and propose a novel algorithm ’AggregateRank’ based on the theory of ...

UNLABELLED We constructed a website for inferring a network by applying the graphical Gaussian model, from a large amount of data, including redundant information. The available tools on the website are based on a system, named ASIAN (Automatic System for Inferring A Network), in combination with the two methods in our previous papers, which were designed to analyze gene expression profiles on ...
