This paper compares established Systems Dynamics (SD) models of software projects with models of agile development. A new minimal SIMULINKTM agile project model was created and compared to a Waterfall model of a NASA project. Results are presented to enable project managers to predict the performance of future agile project processes. The model includes the time to generate the requirements and...

A probabilistic scheduling model for software projects is presented. The model explicitly takes a scheduling strategy as input. When the scheduling strategy is fixed, the model outputs a probability distribution for the project completion time or cost. By applying stochastic optimization techniques, schedules for software projects can be computed which minimize the development time or cost with...

The proper allocation of financial and human resources to the various software development activities is a very important and critical task. To provide a realistic allocation, the project manager of a software development project should account for the various activities needed to ensure the completion of the project with the required quality and on-time and within-budget. In this paper, we pro...

When facing projects with uncertain factors, most of the project managers are interested to secure the pdf of the completion time of the project so as to have full insights into its randomness. For large-size SAN with general types of pdf for the duration of activities, the project managers must turn to the techniques of discretization since the other approaches in the literature become too dem...

Project scheduling problem is to determine the schedule of allocating resources so as to balance the total cost and the completion time. This paper considers project scheduling problem with uncertain activity duration times and presents four new uncertain programming models for different management requirements. Moreover, taking advantage of some properties of uncertainty theory, these models c...

Project scheduling problem is mainly to determine the schedule of allocating resources in order to balance the total cost and the completion time. This paper chiefly uses chance theory to introduce project scheduling problem with uncertain variables. First, two types of single-objective programming models with uncertain variables as uncertain chance-constrained model and uncertain maximization ...

The proper allocation of financial and human resources to the various software development activities is a very important and critical task contributing to the success of the software project. To provide a realistic allocation, the manager of a software development project should account for the various activities needed to ensure the completion of the project with the required quality, on-time...

Completion of the Human Genome Project was announced on April 14, 2003, as the whole human genome was sequenced. The Human Genome Project was proposed in the mid-1980s aiming to sequence the whole human genome. Yet, its realization was thought to be almost impossible since a considerable amount of time was required to complete the whole genome sequencing with the analysis technology at that tim...
