Abstract:

With industrial projects increasing in complexity and size, determining realizable schedules that efficiently utilize limited resources represents one of the most challenging project management tasks. In this context, the well-known resource-constrained project scheduling problem has been extensively studied. However, due to its restrictive assumptions, it allows only partial modelling of real-world scheduling problems. Therefore, this paper deals with a generalized version that considers more evolved types of precedence relationships as well as time-varying resource availabilities, e.g. due to maintenance or vacations. For this problem, appropriate heuristic solution methods, based on priority rules and tabu search, are proposed and evaluated concerning their effectiveness.
