A precedence constrained flow shop scheduling problem with transportation time, breakdown times, and weighted jobs [PDF]

open access: yesJournal of Project Management, 2022
Job precedence can often be seen in various manufacturing process scenarios. For instance, in the context of flow shop scheduling, certain jobs must be processed before a specific job may be executed.

Estimation of mining time-span to improve the solution time in long-term production planning [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2022
Long-term production planning in open-pit mines is a precedence-constraint knapsack problem. A spatial representation of the mining region (called the block-model) is the primary input of mine planning models. One should note that as the number of blocks

Makespan minimization with OR-precedence constraints [PDF]

open access: yesJournal of Scheduling, 2021
AbstractWe consider a variant of the NP-hard problem of assigning jobs to machines to minimize the completion time of the last job. Usually, precedence constraints are given by a partial order on the set of jobs, and each job requires all its predecessors to be completed before it can start.

Scheduling with AND/OR Precedence Constraints [PDF]

open access: yesSIAM Journal on Computing, 2004
In many scheduling applications it is required that the processing of some job must be postponed until some other job, which can be chosen from a pre-given set of alternatives, has been completed. The traditional concept of precedence constraints fails to model such restrictions.

Scheduling the Work of Multiple Construction Crews Working Concurrently in Repetitive Construction Projects [PDF]

open access: yesJournal of Engineering Science and Military Technologies, 2023
In repetitive construction projects such as roads, pipelines and multi-story buildings, schedulers might need to utilize multiple crews to simultaneously construct sub-activities of a particular activity to shorten their duration.

Service Flow Management with deadline and budget Constraints using Genetic Algorithm in Heterogeneous Computing [PDF]

open access: yesIJCI International Journal of Computers and Information, 2019
The service flow management is one from the most challenges especially in heterogeneous environments which has several and various processors for computing. Service flow is used to explain services configuration process when service’s formation according

Compact Models to Solve the Precedence-Constrained Minimum-Cost Arborescence Problem with Waiting Times

open access: yesAlgorithms, 2023
The minimum-cost arborescence problem is a well-studied problem. Polynomial-time algorithms for solving it exist. Recently, a new variation of the problem called the Precedence-Constrained Minimum-Cost Arborescence Problem with Waiting Times was ...

Energy Idle Aware Stochastic Lexicographic Local Searches for Precedence-Constraint Task List Scheduling on Heterogeneous Systems

open access: yesEnergies, 2021
The use of parallel applications in High-Performance Computing (HPC) demands high computing times and energy resources. Inadequate scheduling produces longer computing times which, in turn, increases energy consumption and monetary cost.

The AllDifferent Constraint with Precedences [PDF]

open access: yes, 2011
We propose AllDiffPrecedence, a new global constraint that combines together an AllDifferent constraint with precedence constraints that strictly order given pairs of variables. We identify a number of applications for this global constraint including instruction scheduling and symmetry breaking. We give an efficient propagation algorithm that enforces
