The Impact of Opioid Prescribing Limits on Drug Usage in South Carolina: A Novel Geospatial and Time Series Data Analysis
HEALTHCARE, 11(8).
author keywords: prescription drug abuse; policy analysis; interrupted time series; spatiotemporal classification; ARIMAX; pharmaceutical supply chain
TL;DR:
While South Carolina's prescription limit law effectively reduced opioid prescription volumes overall, an unintended consequence was observed as prescription volume increased in areas where prescribers were located at far distances from patients, highlighting the limitations of state-level policies on doctors.

Integer Programming Techniques for Static Scheduling of Hard Real-Time Systems
IEEE ACCESS, 8, 170389–170403.
author keywords: Task analysis; Real-time systems; Time factors; Scheduling; Optimal scheduling; Schedules; Mathematical model; Integer linear programming; optimization; partitioned systems; real-time systems; static scheduling
TL;DR:
This article proposes an ILP method that reduces by 70% the time needed to obtain an optimal solution compared to basic approaches and achieves better results than heuristics when trying to reduce temporal parameters such as response times, context switches, and jitter.

Optimization of Modular Fixture Setup Time in an Automated Assembly Line
ADVANCES IN DESIGN, SIMULATION AND MANUFACTURING III: MANUFACTURING AND MATERIALS ENGINEERING, VOL 1, pp. 336–346.
author keywords: Changeability; Robot travel path; TSP; Fixture design; MILP
TL;DR:
This paper extends the model presented in the literature in two directions to further reduce the fixture setup time in a mid-volume mid-variety automated production system and introduces a new fixture design that improves the fixture modularity to hold more products with different geometries.

Change management in modular assembly systems to correspond to product geometry change
INTERNATIONAL JOURNAL OF PRODUCTION RESEARCH, 57(19), 6048–6060.
author keywords: Changeable manufacturing; optimisation; automated assembly system; GAMS; MILP
TL;DR:
Two mathematical models are presented to optimise the use of a passive modular assembly fixture plan in an automated assembly system by considering different production scenarios and constraints and can effectively reduce the fixture setup time up to %50.
