Optimizing Effort Parameter of COCOMO II Using Particle Swarm Optimization Method

Estimating the effort and cost of software is an important activity for software project managers. A poor estimate (overestimates or underestimates) will result in poor software project management. To handle this problem, many researchers have proposed various models for estimating software cost. Constructive Cost Model II (COCOMO II) is one of the best known and widely used models for estimating software costs. To estimate the cost of a software project, the COCOMO II model uses software size, cost drivers, scale factors as inputs. However, this model is still lacking in terms of accuracy. To improve the accuracy of COCOMO II model, this study examines the effect of the cost factor and scale factor in improving the accuracy of effort estimation. In this study, we initialized using Particle Swarm Optimization (PSO) to optimize the parameters in a model of COCOMO II. The method proposed is implemented using the Turkish Software Industry dataset which has 12 data items. The method can handle improper and uncertain inputs efficiently, as well as improves the reliability of software effort. The experiment results by MMRE were 34.1939%, indicating better high accuracy and significantly minimizing error 698.9461% and 104.876%

Optimizing Time and Effort Parameters of COCOMO II using Fuzzy Multi-Objective Particle Swarm Optimization

Estimating the efforts, costs, and schedules of software projects is a frequent challenge to software development projects. A bad estimation will result in bad management of a project. Various models of estimation have been defined to complete this estimate. The Constructive Cost Model II (COCOMO II) is one of the most famous models as a model for estimating efforts, costs, and schedules. To estimate the effort, cost, and schedule in project of software, the COCOMO II uses inputs: Effort Multiplier (EM), Scale Factor (SF), and Source Line of Code (SLOC). Evidently, this model is still lack in terms of accuracy rates in both efforts estimated and time of development. In this paper, we introduced to use Gaussian Membership Function (GMF) of Fuzzy Logic and Multi-Objective Particle Swarm Optimization (MOPSO) method to calibrate and optimize the parameters of COCOMO II. It is to achieve a new level of accuracy better on COCOMO II. The Nasa93 dataset is used to implement the method proposed. The experimental results of the method proposed have reduced the error downto 11.89% and 8.08% compared to the original COCOMO II. This method proposed has achieved better results than previous studies

Penentuan Effort Rate pada Estimasi Effort Menggunakan Metode Use Case Point untuk Pengembangan Perangkat Lunak Website Kepemerintahan

Effort estimation using Use Case Point (UCP) method obtained from the multiplication of the UCP with the Effort Rate (ER). Some studies conclude that there is some value of ER used in the calculation of effort estimation. However, the most often used is the ER with value 20 man-hours given by Karner. Disputes about the research that is ER by Karner occurred in 1993, so it is possible that the ER by Karner not suitable when applied in the calculation of effort estimation for the project worked on in 2013 and the years to come. This study used 8 data of governance website software development projects. The data is used to calculate actual effort, making use case diagrams, and calculations UCP estimation. Further level of analysis that is performed correlation and regression equations for actual effort and the UCP estimation. Based on the regression equation then performed calculations tangent ? to produce the ER. From this research produced the ER as big as 5,178 man-hours. The ER is much smaller than the value given by Karner ER. Case is possible for several reasons, among others: 1) Enginering software technology that is growing rapidly. 2) Manufacturing website using components. 3) Source of the internet so complete

Effort Rate on Use Case Point Method For Effort Estimation of Website Development

The purpose of this research is to gain Effort Rate (ER) on the Use Case Point method (UCP) for estimating effort of the website development. The Effort estimation is an activity that is carried out to predict how amount of effort required to complete a software development project. Effort estimation is very important be know before the project is executed to determine how resources should be spent to complete the project. In this context, resources include the work hours and expenses. Commonly UCP was one of method used to estimate software development effort. The studies that have been conducted by several researchers carried out to estimate the regular software development. Until now, it is not found research using UCP to estimate effort for the website development project. The UCP that is used to estimate the effort of website development projects requires different ER from the ER for regular software project. Effort is obtained by multiplying the value of UCP and ER. The ER value proposed by some researchers varies between 18 to 36 staff-hours per UCP, while ER proposed by Karner was 20 staff-hours per UCP. The final results of this study obtain ER value of 4.41. This value is smaller than the value proposed earlier researchers. Decline of the ER values can decrease value of effort estimation, furthermore decline of value effort estimation will decrease resources that it will be required for software development. This may be due to the website development project which can use Content Management System (CMS) as component or framework that facilitate the development of a website project easier
