Analysis of a multimachine flexible manufacturing cell using stochastic Petri nets

Advances in Mechanical Engineering, 2016
In this article, a generalized stochastic Petri net model is developed to analyze the performance of a multimachine flexible manufacturing cell. The analyzed flexible manufacturing cell consists of one or more machine(s), a single conveyor, and a single ...

A Meso-Scale Petri Net Model to Simulate a Massive Evacuation along the Highway System

Future Transportation, 2023
Natural disasters may require that the residents of the affected area be evacuated immediately using a potentially damaged infrastructure. In this paper, we developed a mesoscopic simulation modeling approach for modeling traffic flow over a large ...

Analysis of stochastic Petri nets with signals [PDF]

Performance Evaluation, 2012
Product-form models facilitate the efficient analysis of large stochastic models and have been sought after for some three decades. Apart from the dominating work on queueing networks, some product-forms were found for stochastic Petri nets (SPNs) that allow fork-join constructs and for queueing networks extended to include special customers called ...

Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo

Advanced Healthcare Materials, EarlyView.
This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...

Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

Advanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Maintenance Process Simulation Based Maintainability Evaluation by Using Stochastic Colored Petri Net

Applied Sciences, 2019
Maintainability is a critical design characteristic of products. Maintainability evaluation plays an important role in maintainability design. Existing maintainability evaluation approaches neglect logistic effects on system maintainability.
