Today’s software systems are developed and targeted for satisfying sometimes very critical functions. Reliability is considered to be one of the most important nonfunctional quality attribute of such software systems. The aim of reliability estimation in early stages of software development process – analysis and design – should reduce the future costs for possible failure repairing through inc...

one of the most important aspects of software project management is the estimation of cost and time required for running information system. therefore, software managers try to carry estimation based on behavior, properties, and project restrictions. software cost estimation refers to the process of development requirement prediction of software system. various kinds of effort estimation patter...

In this paper an approach for the estimation of software development costs is presented. The method is based on the characterization of the software to be developed in terms of project and environment attributes and comparison with some similar completed project(s) recovered from a historical database. A case study is also presented, focusing on the calibration and application of the method on ...

The paper presents the results of a novel method for the instruction-level energy consumption measurement and the corresponding modeling approach for embedded microprocessors. According to the proposed method the base and interinstruction energy costs of the ARM7TDMI embedded processor as well as the energy cost due to different values in the instruction parameters are modeled. These models can...

The Constructive Cost Model (COCOMO) is one of the famous software cost estimation model developed by Barry W. Boehm. This model is used to estimate software costs, duration and maintenance efforts early in the development life cycle. COCOMO model has a simple function with two parameters to be estimated. Many techniques were used to estimate those parameters such as fine tuning and better pred...

The growing complexity and number of software projects requires both increasingly more experienced developers, testers and other specialists as well as a larger number of persons to fill these roles. This leads to increased personnel and management costs and also makes effort and cost estimation at task and activity levels more difficult for software development companies. An automated solution...

A model is presented for defect insertion and detection in software development. The model, which is based on a high-level, generic concept of the software life cycle, allows for the estimation of final defect content based on estimates of several process factors: defect insertion rate, defect detection ratio, spreading ratio and traceability factor. It is suggested that the model has potential...

We present an approach for the extraction of computational demand of embedded software components and the determination of initial mapping configurations on modern embedded heterogeneous processor architectures. The presented work combines the advantages of component-based design and properties obtained from source-code analysis. The goal is a very fast estimation of execution costs for multipl...

With component-based reuse, software development is achieved through the planned integration of pre-existing software components. Commercial-off-the-shelf (COTS) Based Development (CBD) is one of the systematic reuse approaches promising gains in cost, operational quality, functionality, time to market and maintenance overheads. This is an increasingly popular paradigm for software development,...
