An indirect search algorithm for disaster restoration with precedence and synchronization constraints

open access: yesPacific Journal of Mathematics for Industry, 2017
When a massive disaster occurs, to repair the damaged part of lifeline networks, planning is needed to appropriately allocate tasks to two or more restoration teams and optimize their traveling routes.

Budget Minimization with Precedence Constraints

open access: yesCoRR, 2019
Budget Minimization is a scheduling problem with precedence constraints, i.e., a scheduling problem on a partially ordered set of jobs $(N, \unlhd)$. A job $j \in N$ is available for scheduling, if all jobs $i \in N$ with $i \unlhd j$ are completed. Further, each job $j \in N$ is assigned real valued costs $c_{j}$, which can be negative or positive.

Approximation algorithms for scheduling malleable tasks under precedence constraints [PDF]

open access: yes, 2001
This work presents approximation algorithms for scheduling the tasks of a parallel application that are subject to precedence constraints. The considered tasks are malleable which means that they may be executed on a varying number of processors in ...

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 ...

Approximate Deadline-Scheduling with Precedence Constraints [PDF]

open access: yes, 2015
We consider the classic problem of scheduling a set of n jobs non-preemptively on a single machine. Each job j has non-negative processing time, weight, and deadline, and a feasible schedule needs to be consistent with chain-like precedence constraints. The goal is to compute a feasible schedule that minimizes the sum of penalties of late jobs. Lenstra

Optimization of multi objective vehicle routing problem using a new hybrid algorithm based on particle swarm optimization and artificial bee colony algorithm considering Precedence constraints

open access: yesAlexandria Engineering Journal, 2018
The vehicle routing problem is the basic problem of distribution planning which seeks to find the best route with minimum displacement cost considering the number of customers, their constraints, and number and capacity of the available vehicles. In this

Handling linear precedence constraints by unification [PDF]

open access: yesProceedings of the 30th annual meeting on Association for Computational Linguistics -, 1992
Linear precedence (LP) rules are widley used for stating word order principles. They have been adopted as constraints by HPSG but no encoding in the formalism has been provided. Since they only order siblings, they are not quite adequate, at least not for German.

Minimizing waiting time under precedence constraints in health examinations

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing
The long waiting time between examinations is a serious issue in hospitals. This study explores how precedence constraints affect waiting times for examinees in health examination scheduling.

A hybrid approach for haptics-based intelligent assembly planning

open access: yesAdvances in Mechanical Engineering, 2016
Assembly planning is normally realized by automatic approach or interactive approach. Both of these methods have promising advantages, but they also have inevitable shortcomings.
