프로그램 코드의 유사도 측정에 대한 방법은 여러 가지 존재하고 있으며 유사도 측정 프로그램도 많이 존재한다. 이런 프로그램 유사도 측정 도구는 중소규모 소프트웨어 프로젝트에 많이 사용되고 있으나, 실제 대규모 소프트웨어의 유사도 검사를 위해서 사용하기에는 한계가 존재한다. 지금까지 대규모 소프트웨어의 유사도를 측정할 수 있는 객관적 방법이 거의 제시되지 않고 있어, 본 논문에서는 대규모 소프트웨어의 소스코드를 요약하여 서로 다른 프로그램의 유사도를 측정하는 방법을 제시한다.

소프트웨어 시스템의 규모 측정은 소프트웨어 개발에 필요한 비용을 산정하거나 필요한 인력 투입. 기간의 산정 등의 중요한 지표가 된다. 1990년대 후반 급격한 인터넷의 발달로 인해 다양한 기술과 웹 사이트가 등장하였다. 기존의 소프트웨어의 규모를 측정하기 위한 방법은 LOC와 기능점수(Function Point)가 있다. 그러나 LOC는 프로그래밍 언어에 의존적이므로 웹 페이지 규모를 측정하기는 한계가 있다. 따라서 웹 페이지 규모를 측정하기 위해 기능점수분석을 사용한다. 본 논문에서는 동일한 웹 페이지를 기존의 기능점수모형과 확장된 기능점수모형으로 분석하여 그 결과를 비교하고 미비점을 보완한다. 또한 다양한 웹 페이지들의 규모를 측정하기 위하여 기존 기능점수분석모형에 추가 조정 인자를 기술하고 확장된 기능점수모형을 제안한다.

Area of software measurement in software engineering is active more than thirty years. There is a huge collection of researches but still no concrete software development effort and cost estimation model. If we want to measure the effort and cost of a software project, we need to estimate the size of the software. A number of software metrics are identified in the literature; the most frequently cited measures are LOC (line of code) and FPA (function point analysis). The FPA approach has features that overcome the major problems with using LOC as a measure of system size. This paper presents simple linear regression model that related software development effort to software size measured in FP. The model is derived from the plotting of the effort and FP relation. The experimental data are collected from 789 software development projects that were recently developed under the various development environments and development methods. Also, the model is compare with other regression analysis model. The presented model has the best estimation ability among the software effort estimation models.

A software size estimation has to be analyzed in the beginning of the software life-cycle and helpful to the prediction of its size and cost. The software cost has been calculated by estimating software size from the user's point of view since the function point method based on international standards was introduced for the estimation of software size in 2004. However, the current function point method is not easy to be exploited for unfamiliar user, and has a problem that it cannot estimate the proper size for software such as engineering software, scientific calculations and simulation with complicated internal computational logic. This paper presents an improved model which can simplify the existing function point measurement procedure, and perform the estimation of software size in easy and fast way at the initial stage of project. Moreover, it presents a mathematical weighted value calculation model which can solve the problem of the fixed complexity weighted value and reflect the characteristics of organization as its data is pilled up. Our evaluation shows that the presented model has advantage that it can measure the size more rapidly than the existing FPA methods and has more correlation with LOC.

The existing Function Point method to estimate the software size has been utilized frequently with the management information system. Due to the expanding usage of the real-time and embedded system, the Full Function Point method is being proposed. However, despite many research is being carried out relation to the software size, the research on the model to estimate the development cost from the measured software size is inadequate. This paper analyzed the linear regression model and power regression model which estimate the development cost from the software FFP The power model is selected, which shows its estimation is most adequate.

소프트웨어 규모산정 활동은 기획, 구현, 운영 등 소프트웨어 수명주기 동안 수행되는 활동으로 프로젝트를 추진함에 있어 예산수립, 사업발주, 사업관리 등에 중요하다. 소프트웨어 규모산정으로 사용되는 기능점수를 측정할 때 개인의 주관적인 판단으로 인해 오차가 발생한다. 본 논문에서는 기능점수 측정의 오차를 줄이기 위해 4가지의 검증로직을 제시하고, 진행되는 실제 프로젝트를 통해 검증하여 제시된 검증로직이 타당함을 보인다.

Area of software measurement in software engineering is active more than thirty years. There is a huge collection of researches but still no a concrete software cost estimation model. If we want to measure the cost-effort of a software project, we need to estimate the size of the software. A number of software metrics are identified in the literature ; the most frequently cited measures are LOC(line of code) and FPA(function point analysis). The FPA approach has features that overcome the major problems with using LOC as a measure of system size. This paper presents an neural networks(NN) models that related software development effort to software size measured in FPs and function element types. The research describes appropriate NN modeling in the context of a case study for 24 software development projects. Also, this paper compared the NN model with a regression analysis model and found the NN model has better estimative accuracy.

Function Point Method have been applied to measure software size estimation in industry because it supports to estimate the software's size by user's view not developer's. However, the current function point method has some problems for example complexity's upper limit etc. So, In this paper, an enhanced function point model. Micro FP model, was suggested. Using this model, software effort estimation can be more efficiently because this model has some regression equation. This model specially can be applied to estimate in detail the large application system's size Analysis results show that measured software size by this Micro FP model has the advantage with more correlative between the one of LOC, as of 10 applications operated in an large organization.

Estimation of development cost, effort and time is difficult and a key problem of software engineering in the early stage of software development. These are estimated by using the function point which is measured from a requirement specification. However, it is often a serious Question of the staffing level required for the software development. The purpose of this paper is to show us the model which can be used to estimate a size of development team. Three hundred one software projects have been analyzed and studied for the model. First, an analysis was conducted for statistical algorithmic model. After various data transformation and regression analysis, it was concluded that no good model was available. Therefore, non-algorithmic model was suggested for analysis, which has random distribution of residuals and makes good performance using RBF (Radial Basis Function) network. Since the model provides a standard to determine the required size of development team, it ran be used as management information.

소프트웨어의 측정은 소프트웨어의 생명주기 초기에 분석되어 규모와 비용의 예측에 도움을 주어야 한다. 초기에는 정확한 LOC 기반 규모예측이 어려워 기능 점수 기반의 측정에 의하여 예측할 수 있다. 그러나 현재의 기능 점수 기반 측정은 모든 시스템에 획일화되어 있어 시스템의 특성을 반영할 수 없으며, IFPUG에서 제시한 일반 시스템 특성은 웹 기반 어플리케이션에서 사용자의 인지도가 매우 낮다. 본 논문에서는 웹 기반 어플리케이션 중에 동적 웹사이트에 특화된 시스템 특성 집합 및 영향도 측정 방법을 제시한다. 이 요소를 근거로 동적 웹사이트의 시스템 특성을 분석하여 기능 정수의 값 조정 인자에 반영하고 실제 시스템을 대상으로 조정된 기능 점수를 산정한다.
