MILP models of a patient transportation problem

Central European Journal of Operations Research
AbstractWith ageing societies and increasing number of patients, there is a growing need for quality services that help transporting non-urgent patients to hospitals. In logistics, patient transportation problems are usually modeled as a dial-a-ride problem.

On MILP Models for the OWA Optimization

Journal of Telecommunications and Information Technology, 2012
The problem of aggregating multiple outcomes to form overall objective functions is of considerable importance in many applications. The ordered weighted averaging (OWA) aggregation uses the weights assigned to the ordered values (i.e., to the largest value, the second largest and so on) rather than to the specific coordinates.

Scheduling optimization of optical lens polishing

International Transactions in Operational Research, Volume 33, Issue 6, Page 3744-3768, November 2026.
Abstract Optical systems have achieved notable progress in focusing and imaging technologies; however, manual grinding remains indispensable, resulting in elevated costs, extended timelines, and inefficiencies. These difficulties are compounded by operational constraints, uneven machine utilization, and risks of order delays and escalating expenses ...
