Over the past 20 years, the topic of order acceptance has attracted considerable attention
from those who study scheduling and those who practice it. In a firm that strives to align its …

The outbreak of COVID-19 dramatically impacts the global economy. Mass COVID-19
vaccination is widely regarded as the most promising way to fight against the pandemic and …

Manufacturing companies are now more conscious about the environment. As such, there
are more concerns in reducing the consumption of energy and the production of pollutants …

In this paper, we consider the single machine scheduling problem with release dates and
rejection. A job is either rejected, in which case a rejection penalty has to be paid, or …

Previous scheduling theory assumes that manufacturers have enough manufacturing
resources (machines), therefore, rental costs and dynamic changes in machine number are …

In this paper, we consider single-machine scheduling problems under the job rejection
constraint. A job is either rejected, in which case a rejection penalty has to be paid, or …

We consider several parallel-machine scheduling problems in which the processing time of
a job is a (simple) linear increasing function of its starting time and jobs can be rejected by …

We consider the bounded single-machine parallel-batch scheduling problem with release
dates and rejection. A job is either rejected, in which case a certain penalty has to be paid …

In this paper, we consider the parallel-machine scheduling problem with release dates and
rejection. A job is either rejected, in which case a rejection penalty has to be paid, or …

Scheduling has become a popular area for artificial intelligence and expert system
researchers during last decade. In this paper, a new metaheuristic algorithm entitled …
