Modeling and Solution Procedure for a Preemptive Multi-Objective Multi-Mode Project Scheduling Model in Resource Investment Problems [PDF]

Journal of Optimization in Industrial Engineering, 2018
In this paper, a preemptive multi-objective multi-mode project scheduling model for resource investment problem is proposed. The first objective function is to minimize the completion time of project (makespan);the second objective function is to ...

SORTING APPROACHES IN THE HEURISTIC BASED ON REMAINING AVAILABLE AND PROCESSING PERIODS TO MINIMIZE TOTAL WEIGHTED TARDINESS IN PROGRESSIVE IDLING-FREE 1-MACHINE PREEMPTIVE SCHEDULING

KPI Science News, 2021
Background. In preemptive job scheduling, total weighted tardiness minimization is commonly reduced to solving a combinatorial problem, which becomes practically intractable as the number of jobs and the numbers of their processing periods increase.

Exact and Heuristic Algorithms for Thrift Cyclic Scheduling

Algorithms, 2009
Non-preemptive schedulers, despite their many discussed drawbacks, remain a very popular choice for practitioners of real-time and embedded systems. The non-preemptive ‘thrift’ cyclic scheduler—variations of which can be found in other application areas ...

Scheduling Mixed-Criticality Systems on Varying-Speed Processors: A Meta-Reinforcement Learning Approach for Non-Preemptive Tasks

IEEE Access
Mixed-Criticality (MC) systems have to guarantee the timely execution of high-criticality tasks even under adversarial processor conditions. Prior work addresses preemptive scheduling, leaving the NP hard, non-preemptive scheduling problem unexplored ...

New procedures with new activity assumptions for solving resource constrained project scheduling problems [PDF]

Journal of Project Management, 2020
The resource-constrained project scheduling problem (RCPSP) is a well-known and widely studied topic. The underlying problem assumes that non-preemptions and that constant resources are restrictions imposed on project activities, which are to be ...
