creating a plan for the project by choosing different modes of execution, assigning task start times, managing resources, etc. After the plan is ready the user can advance the simulation time. The PTB engine randomly generates different parameters to simulate the stochastic nature of real projects. The user has to continuously monitor the project and react to the non-deterministic events. The project fails if the cash flow runs negative. Once the user completes the project a final score is presented based on benefits and costs of the solution. The topics covered by the PTB are: Project planning Scope and requirements management Cost–benefit analysis Project monitoring Project control Resource management Cash management Risk management Scheduling Publications The book "Project Management Simulation with PTB Project Team Builder" was published by Springer Science+Business Media in March 2012. Research based on the PTB was conducted at institutes such as MIT, Technion, Pennsylvania State University, Drexel University and Australian National University. Some of this research was published in scientific Journals: "Simulation-based Learning: The Learning-Forgetting-Relearning Process and Impact of Learning History" – this study focused on the development and application of History mechanisms for simulation based training. Different types of such mechanisms were tested in a controlled experiment and evaluated based on their effectiveness as Training tools. "The Impact of Functional Fidelity in Simulator based Learning of Project Management" – this study focused on the importance of flexibility in generating scenarios for simulation based training. As a result of this study the simulation engine and the scenario editor were separated to allow the trainee to develop the scenario that fits his needs in the best possible way. "Comparing Competitive and Cooperative Strategies for Learning Project Management" – this study compared teaching strategies in simulation based training environments. A controlled Experiment revealed that a mixed strategy is preferred starting with individual training and moving to Teamwork where weak students work with strong performers as teams. "Guest Editorial: The Use of Simulation in Learning and Teaching" – this special issue focused on the use of simulation based training for Engineering education. A large variety of applications is present along with some important insight for future development. "Simulator-based Team Training to Share Resources in a Matrix Structure Organization" – this study focused on the use of simulation based training for team training by simulation in the Matrix organization. Communication issues and planning issues were investigated in a controlled Experiment.
