Summary
Controlling the aviation supply chain network is best achieved by applying control inputs to upstream suppliers. This strategy yields superior results compared to targeting core enterprises or downstream distributors.
Area of Science:
- Operations Research
- Supply Chain Management
- Network Analysis
Background:
- Aviation supply chains are complex systems requiring robust control mechanisms.
- Understanding network controllability is crucial for operational efficiency and resilience.
Purpose of the Study:
- To establish a judgment criterion for the structural controllability of aviation supply chain networks.
- To determine the optimal placement of control inputs for maximum effect within the network.
Main Methods:
- Analysis of structural controllability criteria for supply chain networks.
- Simulation of control input application at various network nodes (core enterprises, upstream suppliers, downstream distributors).
Main Results:
- The effectiveness of control input varies significantly based on the node targeted.
- Applying control to upstream suppliers demonstrates the most significant positive impact on network controllability.
- Control input applied to downstream distributors yields the weakest effect.
Conclusions:
- Upstream suppliers are the most effective control nodes in the aviation supply chain network.
- Targeting core enterprises offers a moderate control effect, superior to distributors.
- Strategic application of control inputs is vital for optimizing aviation supply chain performance.

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.

Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...
