This paper addresses the critical challenge of optimal allocation and scheduling Internet Things (IoT) tracking devices for patient monitoring in healthcare facilities, where limited resources must be efficiently distributed to minimize cost maximize care quality. We formulate this management problem as a specialized variant Resource-Constrained Scheduling Problem that incorporates patient-specific factors such duration stay priority. After establishing computational complexity problem, we...
Consideration about the possibility to integrate vague uncertainty notions into numerical simulation modeling tools may be a very interesting research field. In this way, it will possible exploit more efficient and robust evaluation in study of high productivity flexibi lity production systems. literature, few works investigated on cope with lack models able deal ill-defined uncertainty. particular, if is describe by statistical distribution, methods classical discrete event theory are model...

This study presents an optimisation model for scheduling homebound vaccination in a more efficient way to address the existing workforce management challenge. We consider home healthcare routeing challenge people be vaccinated at based on limited resources. There are different types of patients that categorised services they require and should served by appropriate teams or single medical staff, where transported rental vehicles. In this context, our goal is minimise total cost...
In this paper, we study the single-vehicle routing problem (VRP) with time windows, multi-shift, and fuzzy uncertainty. problem, one vehicle is used repeatedly to serve demand over a planning horizon of several days.
