Dynamical Simulation Models of the Open Source Development Process
نویسنده
چکیده
This chapter will discuss attempts to produce formal mathematical models for dynamical simulation of the development process of Free/Open Source Software (F/OSS) projects. First, a brief overview for simulation methods of closed source software development is given. Then, based on empirical facts reported in F/OSS case studies, we describe a general framework for F/OSS dynamical simulation models and discuss its similarities and differences to closed source software simulation. A specific F/OSS simulation model is introduced. The model is applied to the Apache project and to the gtk+ module of the GNOME project, and simulation outputs are compared to real data. The potential of formal F/OSS simulation models to turn into practical tools used by F/OSS coordinators to predict key project factors is demonstrated. Finally, issues for further research and efforts for improvement of this first-attempt model are discussed.

Dynamical Simulation Models for the Development Process of Open Source Software Projects
There have been a few studies attempting to define the Open-Source software (OSS) development process in general terms and there have also been a few case studies of OSS projects. The latter studies presented qualitative and quantitative data for the OSS development process, managerial issues and programmer attitudes. The authors in many cases offer descriptive explanations based on plausible a...
متن کاملA novel simulation model for the development process of open source software projects
The present paper presents a first attempt to produce a dynamical simulation model for the development process of open source software projects. First, a general framework for such models is introduced. Then, a specific simulation model is described and demonstrated. The model equations are based on available literature case studies whenever possible or reasonable assumptions when literature da...
متن کاملA Novel Software Evolution Model Based on Software Networks
Many published papers analyzed the forming mechanisms and evolution laws of OO software systems from software reuse, software pattern, etc. There, however, have been fewer models so far merely built on the software components such as methods, classes, etc. and their interactions. In this paper, a novel Software Evolution Model based on Software Networks (called SEM-SN) is proposed. It uses soft...
متن کاملA model for the dynamical study of food-chain system considering interference of top predator in a polluted environment
The modeling investigation in this paper discusses the system level effects of a toxicant on a three species food chain system. In the models, we have assumed that the presence of top predator reduces the predatory ability of the intermediate predator. The stability analysis of the models is carried out and the sufficient conditions for the existence and extinction of the populations under the ...
متن کاملDYNAMICAL SIMULATION OF UNDERWATER SOUND PROPAGATION IN THE HORMOZ STRAIT
Providing an illustration of sound propagation in the Hormoz Strait ,this paper is about acoustic wave propagation in shallow water for a harmonic point source with low frequency, less than 1000 and solution of a homogenous Helmholtz equation using parabolic equation. C++ programming is used to solve Helmholtz equation [9] and MATLAB software is used to illustrate figures and animate them [6], ...
