In modern Industry 4.0 environments, real-time scheduling presents a complex challenge requiring both formal correctness guarantees and optimal performance. Background: Traditional approaches fail to provide an optimal integration between formal correctness guaranteeing and optimization, and...

Background: The Vehicle Routing Problem with Time Windows (VRPTW) has been extensively researched due to its applicability across various real-world domains, including logistics, healthcare, and distribution systems. With the global elderly population projected to continue increasing, the demand...

The estimation of costs allocated to each customer when serving them in a collaborative logistic operation is a complex problem whose solution is computationally very expensive. In this work the case of central horizontal collaboration for vehicle routing problems with time windows and a central...

We revisit a service provider's problem to match supply and demand via an online appointment system such as a doctor in the health care sector. We identify in a survey that an extensive set of available appointments leads to significantly less demand because customers infer a lower quality of...

Due to the uncertain nature of the traffic system, it is not trivial for delivery companies to reliably satisfy customers' time windows. To guarantee the reliability of the pickup and delivery service under stochastic and time-dependent travel times, we consider a pickup and delivery problem...

In recent years, patient unpunctuality has become a common problem for mental clinics. The unpunctuality rate has a substantial impact on several quality metrics, including the usage of resources and patient waiting times. Thus, the primary aim of this study is to examine the effectiveness of...

For the flexible job shop (FJSP) completion time prediction problem considering environmental noise, the mathematical model of the problem, the sample generator and the completion time prediction model based on AE-CNN-LSTM are constructed. Firstly, to address the problem that workshop data is...

Because customers must usually arrange their schedules to be present for home services, they desire an accurate estimate of when the service will take place. However, even when firms quote large service time windows, they are often missed, leading to customer dissatisfaction. Wide time windows...
