The bounded core for games with precedence constraints [PDF]
In this paper, the authors consider cooperative games in which there are restrictions on cooperation. These restrictions are modeled by a hierarchical structure on the set of players (cf. [\textit{U. Faigle} and \textit{W. Kern}, Int. J. Game Theory 21, No.

On-Line Scheduling with Precedence Constraints
The on-line problem of scheduling jobs with precedence constraints on \(m\) machines, is considered. The authors concentrate in two models, the model of uniformly related machines and the model of restricted assignment. For the related machines model, it is shown a lower bound of \(\Omega(\sqrt{m})\) for the competitive ratio of deterministic and ...

Periodic schedules for linear precedence constraints
We consider the computation of periodic cyclic schedules for linear precedence constraints graphs: a linear precedence constraint is defined between two tasks and induces an infinite set of usual precedence constraints between their executions such that the difference of iterations is a linear function. The objective function is the minimization of the

INCREMENTAL FILTERING ALGORITHMS FOR PRECEDENCE AND DEPENDENCY CONSTRAINTS [PDF]
Precedence constraints specify that an activity must finish before another activity starts and hence such constraints play a crucial role in planning and scheduling problems. Many real-life problems also include dependency constraints expressing logical relations between the activities – for example, an activity requires presence of another activity ...

Single-Machine Scheduling with Mixed Precedence Constraints
Summary: The paper deals with a single machine scheduling problem involving a general precedence structure that permits both ordinary and fuzzy precedence constraints. Feasible schedules are evaluated not only by their cost but also by the degree of satisfaction with their precedence structure.

Analytic Hierarchy Process and Multilayer Network-Based Method for Assembly Line Balancing
Assembly line balancing improves the efficiency of production systems by the optimal assignment of tasks to operators. The optimisation of this assignment requires models that provide information about the activity times, constraints and costs of the ...

The AllDifferent Constraint with Precedences [PDF]
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

On Stochastic Scheduling with In-Tree Precedence Constraints [PDF]
The authors consider the problem of optimally scheduling a set of jobs obeying in-tree precedence constraints when a number of processors is available. It is assumed that the service times of different jobs are independent identically distributed random variables.
