projects scheduling by the project portfolio selection, something that has its own complexity and its flexibility, can create different composition of the project portfolio. an integer programming model is formulated for the project portfolio selection and scheduling.two heuristic algorithms, genetic algorithm (ga) and simulated annealing (sa), are presented to solve the problem. results of cal...

Objective: The aim of this paper is to propose a new approach to assess the aggregated impact of risks on the completion cost of a construction project. Such an aggregated impact includes the main impacts of risks as well as the impacts of interactions caused by dependencies among them. Methods: In this study, Monte Carlo simulation and Bayesian Networks methods are combined to present a frame...

Currently, open source software communities are thriving and the number of projects that are available through well known code repositories is rapidly increasing over the years. The amount of code that is freely available to developers facilitates high reuse opportunities. One of the major concerns of developers when reusing code is the quality of the code that is going to be reused. Design pat...

The pervasive use of information and communication technology (ICT) in modern societies enables countless opportunities for individuals, institutions, businesses and scientists, but also raises difficult ethical and social problems. In particular, ICT helped to make societies more complex and thus harder to understand, which impedes social and political interventions to avoid harm and to increa...

This paper analyzes the optimal design of stock option vesting conditions when the CEO faces a risk of being replaced at an interim date. First, I show that long vesting terms do not necessarily discourage but in fact can encourage short-termism. Second, the model demonstrates that the optimal vesting schedule involves balancing incentives for managerial effort with incentives for long-term inv...

Sensitivity Analysis (SA) is a key element in the Performance Assessment (PA) of a Radioactive High Level Waste (HLW) Repository. It helps gaining information about the system, understanding the relation between input parameters and output variables and steering new experimental and theoretical research to increase the degree of knowledge about the system. The Integrated Project (IP) PAMINA is ...
