This study was conducted to investigate the problem of robust integrated project scheduling and material ordering in terms of resource constraints, uncertainty, and lag times. Simultaneous consideration of discount, non-renewability, perishability, uncertainty, and different project...

Advance patient scheduling plays a pivotal role in improving service quality and ensuring efficiency in healthcare systems. It is a daily task that health providers need to deal with in order to minimize patients' waiting times while trying to utilize the available resources efficiently. Despite...

Internet healthcare is becoming increasingly popular, which allows doctor–patient communication through messages, phone calls, or videos. Considering stochastic heterogeneous behaviors of patients and physicians (e.g. time-dependent no-shows, service times), it is critical to determine the...

Overall energy efficiency is crucial for green production and carbon dioxide emission, especially for energy-intensive industries such as steel making. To deal with unrelated parallel machine scheduling for steelmaking-continuous casting that is the bottleneck and energy-intensive process, this...

An increasing number of construction projects are adopting prefabrication to economize on time, labor, and materials. This method calls for prudent supply chain management, because its performance relies on coordination between the contractor and supplier. Studies in construction management,...

Most public facilities in the European countries, including France, Germany, and the UK, were built during the reconstruction projects between 1950 and 1980. Owing to the deteriorating state of such vital infrastructure has become relatively expensive in the recent decades. A significant part of...

As satellite communications emerge, meeting the deadline requirement of data flow concentrates more on the trade-off between the route lengths and capacities, since the propagation delay becomes more outstanding in satellite networks.To deal with the transmission optimization problems of...

Effective personnel scheduling is crucial for organizations to match workload demands. However, staff scheduling is sometimes affected by unexpected events, such as the COVID-19 pandemic, that disrupt regular operations. Limiting the number of on-site staff in the workplace together with regular...

To further constrain the carbon emission of the integrated energy system (IES) and reduce the comprehensive cost, an optimal scheduling model to balance economy and low carbon in a real-time price (RTP) environment was proposed. In this model, a low carbon operation strategy considering a reward...
