Use of simulation model for measurement of MilkRun system performance

Open Engineering, 2019
Intra-plant transport systems within their operation directly impact on the performance of production systems. For their effective operation, it is, therefore, necessary to realize evaluation of operational performance and effectivity.

A heuristic-assisted deep reinforcement learning algorithm for flexible job shop scheduling with transport constraints

Complex & Intelligent Systems
Automated guided vehicles (AGVs) are widely used for transportation in flexible job shop (FJS) systems, and their transportation task scheduling has the same substantial impact on production efficiency as machine scheduling does. However, traditional FJS

Testing AGVs in Dynamic Warehouse Environments

, 2006
Automatic Guided Vehicles (AGVs) are unmanned vehicles that can transport loads in a warehouse. AGVs are instructed by on-board AGV control software. As multiple AGVs operate in a decentralized manner in the warehouse environment, conflicts may arise. Consequently, it is crucial to test thoroughly whether the AGV control software actually handles the ...

An asymptomatic geminivirus activates autophagy and enhances plant defenses against diverse pathogens

Stress Biology
Plant viral diseases cause great losses in agricultural production. Virus cross-protection is a strategy in which a mild virus is employed to shield plants against subsequent infections by severe viral strains.
