Classical methods are based on mathematical programming and can solve this problem when the complexity is low. And there are some heuristics and meta-heuristics that are able to provide good schedules for more complex problems [9]. The traditional scheduling and control systems propose hierarchical and centralized architectures, where a classical scheduler system that has a global model of the multi-project environment makes schedules according to the current state of the system. Hans et al. [4] review existing literature in hierarchical approaches and propose a generic project planning and control framework for helping management to choose between planning methods, depending on organisational issues. But these techniques are not flexible or robust enough, and have difficulties to consider many real factors. In addition, real
environments undergo frequent changes (new resources, new technologies) that force to modify the scheduling system. The traditional scheduling and control systems, which are based on
hierarchical and centralized architectures, have not enough flexibility to adapt themselves to the dynamism and complexity of multi-project environments.
