A classification of predictive-reactive project scheduling procedures

Uncertain Resource Availabilities: Proactive and Reactive Procedures for Preemptive Resource Constrained project Scheduling Problem

Project scheduling is the part of project management that deals with determining when intime to start (and finish) which activities and with the allocation of scarce resources to theproject activities. In practice, virtually all project managers are confronted with resourcescarceness. In such cases, the Resource-Constrained Project Scheduling Problem (RCPSP)arises. This optimization problem has...

Robust and reactive project scheduling A review and classification of procedures

A hybrid GRASP algorithm for minimizing total weighted resource tardiness penalty costs in scheduling of project networks

In this paper, we consider scheduling of project networks under minimization of total weighted resource tardiness penalty costs. In this problem, we assume constrained resources are renewable and limited to very costly machines and tools which are also used in other projects and are not accessible in all periods of time of a project. In other words, there is a dictated ready date as well as a d...

Wizard: A System for Predictive, Reactive and Interactive Multi-Resource Scheduling

Of the many production planning and control systems available today almost none deal with the scheduling of multi-resource operations in short-term scheduling, i.e., within the next few days. In short-term scheduling both predictive and reactive usage is important. An initial plan must be created predictively; this can be done periodically. As soon as changes become necessary, e.g. by unforesee...

An approach to predictive-reactive scheduling of parallel machines subject to disruptions

In this paper, a new predictive-reactive approach to a parallel machine scheduling problem in the presence of uncertain disruptions is presented. The approach developed is based on generating a predictive parallel machine scheduling in such a way as to absorb the effects of possible uncertain disruptions through adding idle times to the job processing times. The uncertain disruption considered ...
