چکیده

Software projects are required to be tracked during their execution for controlling them. According to state space approach, the tracking problem leads us to have a project state transition model and project status model. A key factor in modeling software projects is to model the project with uncertainty involved in the parameters related to project state transition model and project status model. Traditional/Hybrid software project tracking technique is formulated, modeled with state space approach in plan-space and execution-space, and simulated using discrete event simulation. The uncertainty considered here is ontological that modeled as a normal distribution using an approximation method. The state space model consists of project-state transition equation and project-measurement equation, in plan-space, and it is formulated with Monte Carlo method in execution-space. The developed state space model is used to track status of the traditional/hybrid project. The project is executed with an iterative and incremental development process. With Monte Carlo simulation runs, simulation result shows the variation in ontological uncertainty iteration-wise, both individually and cumulatively, and the effect of uncertainty on project status, by showing project status in execution-space and plan-space. Besides, the project completion somewhere during the last iteration is shown with simulation. Key-Words: Ontological Uncertainty, Normal Distribution function, State-Space Model, Traditional Project, Hybrid Project, Monte Carlo Simulation, Discrete Event Simulation, Execution-Space, Plan-Space.

New Maximum Power Point Tracking Technique Based on P&O Method

In the most described maximum power point tracking (MPPT) methods in the literatures, the optimal operation point of the photovoltaic (PV) systems is estimated by linear approximations. However, these approximations can lead to less optimal operating conditions and significantly reduce the performances of the PV systems. This paper proposes a new approach to determine the maximum power point (M...
