Nowadays a vast and growing body of open source software (OSS) project data is publicly available on the internet. Despite this public body of project data, the field of software analytics has not yet settled on a solid quantitative base for basic properties such as code size, growth, team size, activity, and project failure. What is missing is a quantification of the base rates of such propert...

the value of wetlands is receiving increasing attention and the cost–benefit analyses (cba) is essential to evaluate the long-term effects of wetland rehabilitation projects. in order to guarantee the water quality of the south-to-north water diversion project of china (east route), the government of shandong province started a huge lakeshore wetland rehabilitation project in 2008. the cba appr...

Software project management has always faced challenges that have often had a great impact on the outcome of projects in future. For this, Managers of software projects always seek solutions against challenges. The implementation of unguaranteed approaches or mere personal experiences by managers does not necessarily suffice for solving the problems. Therefore, the management area of software p...

Nowadays, large projects are developed by globally distributed developer teams. Global Software Development (GSD) is currently not supported by appropriate tools but with the tools designed for on-site development. In this work we analyze benefits of a peer-to-peer approach to integrated environment for GSD, analyze its requirements from selected industrial field studies, and present the archit...

This paper presents a method for optimizing oil production on large scale production networks such as the Troll west field in the North Sea. The method is based on piecewise linearization of all nonlinearities, and on decomposition of the full scale problem into smaller sub-problems. Column generation in a Branch & Price framework is used to solve the decomposed problem. The methods differs fro...

during recent years oil products has decreased because of growing population and increasing demand to oil products and decreasing of crude oil extraction at compare to export. however, to achieve suitable levels of production, the use of improved technologies should be considered. another way to prevent the evaporation and leakage from oil storage tanks and their products are using of storage t...

due to project evaluation complexity and resource constraints, the project portfolio optimization is numerous decision making challenges. hence, many researches have been done to introduce model and methods for portfolio optimization. but most of them have not considered the interaction between projects. considering the interactions between projects increase complexity of portfolio optimization...
