The paper describes an algorithm for the generation of a general class of precedence- and resource-constrained scheduling problems. Easy and hard instances for the single- and multi-mode resource-constrained project scheduling problem are benchmarked by using the state of the art...

We consider the resource-constrained project scheduling problem (RCPSP). The focus of the paper is on a formal definition of semi-active, active, and non-delay schedules. Traditionally these schedules establish basic concepts within the job shop scheduling literature. There they are usually...

This paper describes recents developments in computer-based project-scheduling. The focus is on the resource-constrained project scheduling problem, a backbone-model of Software packages for project management. Based on a parametric characterisation of instances we provide new methods, which...

We present a set of benchmark instances for the evaluation of Solution procedures for single- and multi-mode resource-constrained project scheduling problems. The instances have been systematically generated by the Standard project generator ProGen. They are characterized by the input-parameters...
