Greedy randomized dispatching heuristics for the single machine scheduling problem with quadratic earliness and tardiness penalties [PDF]

In this paper, we present greedy randomized dispatching heuristics for the single machine scheduling problem with quadratic earliness and tardiness costs, and no machine idle time. The several heuristic versions differ, on the one hand, on the strategies

Covalent Organic Frameworks in Smart Food Packaging: Advances, Challenges, and Future Prospects

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Food preservation challenges have positioned packaging as a rapidly evolving, innovation‐driven field, with smart packaging offering transformative solutions. Among advanced materials, covalent organic frameworks (COFs) have attracted growing attention due to their permanent porosity, structural tunability, high surface area, and chemical ...

Improved Heuristics for the Early/Tardy Scheduling Problem with No Idle Time [PDF]

In this paper we consider the single machine earliness/tardiness scheduling problem with no idle time. We present two new heuristics, a dispatch rule and a greedy procedure, and also consider the best of the existing dispatch rules.

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 ...

Practical solutions for a dock assignment problem with trailer transportation. [PDF]

We study a distribution warehouse in which trailers need to be assigned to docks for loading or unloading. A parking lot is used as a buffer zone and transportation between the parking lot and the docks is performed by auxiliary resources called terminal

The impact of public drop‐off boxes and autonomous delivery robots in last‐mile delivery

International Transactions in Operational Research, Volume 33, Issue 6, Page 3825-3854, November 2026.
Abstract The growing concern over emissions from last‐mile logistics is motivating the development of innovative delivery models aimed at reducing environmental impact and traffic congestion. To this end, we propose a last‐mile delivery scheme based on both public drop‐off boxes and autonomous delivery robots.

Comparative Policy Analysis of Healthcare Healthy Eating Policies in Canada

Health Promotion Journal of Australia, Volume 37, Issue 4, October 2026.
ABSTRACT Background Healthy eating policies are of growing importance to the management of retail food environments in healthcare (e.g., hospital cafeterias). Several researchers have begun to analyse health promoting benchmarks within these policies. However, little is understood about the relationship between policy and continuous quality improvement
