Scheduling with monotonous earliness and tardiness penalties

Article Abstract:

The one-machine-model with deterministic processing times is described on the basis of common due date case constraints. The model is then compared to the equal slack due date model. The only constraint used is the sum of similar functions f of the lateness, monotonous with respect to the absolute lateness. Consequently, an optimal schedule with a pseudopolynomial algorithm is developed from resulting structures of an optimal schedule, which includes performance without slack times and a V-shape.

Scheduling projects with variable-intensity activities: the case of dynamic earliness and tardiness costs

Article Abstract:

Four dynamic models were developed to a provide solution to the problem of resource-constrained multiple-project scheduling with variable-intensity activities. The proposed models were designed using four types of precedence relations that reduce costs incurred because of dynamic earliness and tardiness of project activities. Computational experiments of the four models show that they are efficient in providing quality schedules for resource-constrained multi-projects.
