Integrated multi-objective process planning and flexible job shop scheduling considering precedence constraints

open access: yesProduction and Manufacturing Research: An Open Access Journal, 2018
Process planning and scheduling decisions are independently performed in a manufacturing system in traditional approaches. Integration of these two decisions provides significant benefits such as enhancing the productivity of manufacturing resources ...

On the Approximability of Single-Machine Scheduling with Precedence Constraints [PDF]

open access: yesMathematics of Operations Research, 2011
We consider the single-machine scheduling problem to minimize the weighted sum of completion times under precedence constraints. In a series of recent papers, it was established that this scheduling problem is a special case of minimum weighted vertex cover.

Bicriteria Vehicle Routing Problem with Preferences and Timing Constraints in Home Health Care Services

open access: yesAlgorithms, 2019
Home Healthcare (HHC) is an emerging and fast-expanding service sector that gives rise to challenging vehicle routing and scheduling problems. Each day, HHC structures must schedule the visits of caregivers to patients requiring specific medical and ...

Ordering with precedence constraints and budget minimization

open access: yesCoRR, 2015
We introduce a variation of the scheduling with precedence constraints problem that has applications to molecular folding and production management. We are given a bipartite graph $H=(B,S)$. Vertices in $B$ are thought of as goods or services that must be \emph{bought} to produce items in $S$ that are to be \emph{sold}. An edge from $j\in S$ to $i\in B$

A GENETIC ALGORITHM FOR THE RESOURCE CONSTRAINED PROJECT SCHEDULING PROBLEM (RCPSP)

open access: yesInvestigación & Desarrollo, 2008
This paper proposes a Genetic Algorithm (GA) for the Resource Constrained Project Scheduling Problem (RCPSP). Resources are renewable and there is a unique way to perform the activities.

Adaptive Decision and Robust Control Under Parallel Precedence Constraints in Human Strategy Modeling

open access: yesIEEE Access, 2017
In order to disclose possible links and implications pertaining to aircraft performance, flight safety, and human factors in the aviation system, an optimal controller, a robust controller, and an adaptive decision maker were devised and organized within

A Constraint Programming approach to solve the clustering problem in open-pit mine planning [PDF]

open access: yesREM: International Engineering Journal
Since the open-pit precedence-constrained production scheduling problem is an NP-hard problem, solving it is always a challenging task, especially from a long-term perspective because a mineral deposit containing millions of blocks would require several ...
