Computer control of manufacturing systems offers many benefits for the improvement of production processes. Some of the main benefits are:
Improved quality and productivity
Computer control systems can monitor and adjust the parameters and conditions of the manufacturing system to ensure that the products or services meet the specifications and standards of quality. They can also detect and correct errors, faults, and defects in real-time. This reduces the need for human inspection, rework, scrap, and warranty costs.
Computer control systems can also optimize the utilization and coordination of the resources and activities of the manufacturing system to increase the output and efficiency. They can also reduce the setup time, changeover time, idle time, and downtime of the machines and workers. This enhances the productivity and profitability of the production operations.
Reduced costs and waste
Computer control systems can reduce the costs and waste associated with the manufacturing system by minimizing the consumption of energy, materials, labor, and space. They can also improve the inventory management, material handling, and logistics of the manufacturing system by synchronizing the supply and demand of the inputs and outputs. This lowers the inventory levels, transportation costs, and environmental impacts.
Enhanced flexibility and adaptability
Computer control systems can enhance the flexibility and adaptability of the manufacturing system by enabling it to respond quickly and effectively to changes in customer requirements, market conditions, product designs, or production technologies. They can also facilitate the customization and personalization of products or services by allowing variations in features, functions, or specifications. This increases the customer satisfaction and loyalty.
Challenges of Computer Control of Manufacturing Systems
Computer control of manufacturing systems also poses some challenges for the design, implementation, and operation of production processes. Some of the main challenges are:
Complexity and reliability issues
Computer control systems are complex systems that involve multiple components, interactions, feedbacks, uncertainties, disturbances, and constraints. They require sophisticated algorithms, software, hardware, and interfaces to function properly. They also depend on accurate data collection, processing, transmission, and storage. Therefore, they are prone to errors, failures, malfunctions, or cyberattacks that can compromise their performance, reliability, or safety.
To overcome these issues, computer control systems need to be carefully designed, tested, verified, validated, maintained, and updated. They also need to have robustness, resilience, redundancy, fault-tolerance, self-diagnosis, and self-recovery capabilities.
Security and privacy risks
Computer control systems are connected to various networks and devices that can expose them to unauthorized access or manipulation by hackers or malicious agents. These can result in data breaches, information leaks, identity theft, fraud, sabotage, or espionage that can damage the reputation, competitiveness, or security of the manufacturing system or its stakeholders.
To prevent these risks, computer control systems need to have strong encryption, authentication, authorization, and auditing mechanisms. They also need to comply with relevant laws, regulations, standards, and ethics regarding data protection, privacy, and cybersecurity.
Human factors and social implications
Computer control systems affect the roles, responsibilities, skills, and behaviors of the human workers and managers in the manufacturing system. They can also impact the quality of work life, job satisfaction, motivation, and well-being of these people. They can also create new opportunities or challenges for employment, education, training, or career development.
To address these factors and implications, computer control systems need to be designed with human-centered principles and values. They also need to foster human-machine collaboration, communication, and coordination. They also need to support human learning, creativity, and innovation.
Components of Computer Control of Manufacturing Systems
Computer control systems consist of three main components: sensors and actuators; controllers and computers; communication networks and protocols.
Sensors and actuators
Sensors are devices that measure physical quantities such as temperature; pressure; force; position; speed; acceleration; voltage; current; or light intensity from the manufacturing system. They convert these quantities into electrical signals that can be processed by computers.
Controllers and computers
Controllers are devices that implement control algorithms or rules to regulate the behavior of the manufacturing system. They use the signals from the sensors to calculate the desired values or commands for the actuators. They can be classified into two types: open-loop controllers and closed-loop controllers.
Open-loop controllers do not use feedback from the manufacturing system to adjust their commands. They assume that the system behaves as expected and that there are no disturbances or uncertainties. They are simple, fast, and cheap, but they can be inaccurate, unreliable, or unstable.
Closed-loop controllers use feedback from the manufacturing system to correct their commands. They compare the actual values of the system variables with the desired values and generate error signals that are used to modify their commands. They can compensate for disturbances or uncertainties and improve the accuracy, reliability, or stability of the system.
Computers are devices that perform data processing, storage, and communication functions for the computer control systems. They can be classified into two types: centralized computers and distributed computers.
Centralized computers are located in a single location and have a global view and control of the manufacturing system. They can perform complex calculations, store large amounts of data, and communicate with multiple devices. They are powerful, fast, and consistent, but they can be expensive, vulnerable, or inefficient.
Distributed computers are located in multiple locations and have a local view and control of the manufacturing system. They can perform simple calculations, store small amounts of data, and communicate with nearby devices. They are cheap, robust, and flexible, but they can be limited, slow, or inconsistent.
Communication networks and protocols
Communication networks are systems that enable the exchange of information among the components of the computer control systems. They can be classified into two types: wired networks and wireless networks.
Wired networks use physical cables or wires to transmit electrical signals among the components. They can provide high bandwidth, low latency, low interference, and high security. They are reliable, stable, and easy to monitor, but they can be costly, rigid, or difficult to install or maintain.
easy to install or maintain, but they can have low bandwidth, high latency, high interference, or low security. They are susceptible to noise, fading, jamming, or hacking.
Communication protocols are sets of rules or standards that define how the components of the computer control systems communicate with each other. They specify the format, content, timing, and sequence of the messages or signals that are exchanged. They also provide mechanisms for error detection, correction, encryption, authentication, or synchronization.
Some of the common communication protocols used in computer control systems are: TCP/IP (Transmission Control Protocol/Internet Protocol), which is the basis of the internet and enables data transmission across different networks; Modbus, which is a serial communication protocol that allows data exchange between industrial devices such as PLCs (Programmable Logic Controllers), sensors, and actuators; CAN (Controller Area Network), which is a bus network protocol that enables data transmission among multiple devices in a vehicle; and MQTT (Message Queuing Telemetry Transport), which is a publish-subscribe protocol that enables data transmission among multiple devices in an IoT (Internet of Things) system.
Types of Computer Control of Manufacturing Systems
Computer control systems can be classified into three main types based on their architecture or structure: hierarchical control systems; distributed control systems; and intelligent control systems.
Hierarchical control systems
Hierarchical control systems are composed of multiple levels of controllers and computers that have different functions and responsibilities. The higher levels have more authority and information than the lower levels. The lower levels have more autonomy and interaction than the higher levels. The communication among the levels is vertical and top-down or bottom-up.
Hierarchical control systems can provide a clear division of tasks, a consistent coordination of activities, and a centralized decision making. They can also handle complex and large-scale manufacturing systems. However, they can also suffer from delays, bottlenecks, conflicts, or inconsistencies among the levels. They can also be rigid, inflexible, or inefficient in responding to changes or uncertainties.
Distributed control systems
Distributed control systems are composed of multiple controllers and computers that have similar functions and responsibilities. They are connected by a communication network that allows them to exchange information and cooperate with each other. The communication among them is horizontal and peer-to-peer.
modularity, scalability, and reliability. They can also handle dynamic and uncertain manufacturing systems. However, they can also suffer from communication overhead, coordination complexity, or consensus difficulty. They can also be vulnerable to cyberattacks or malicious behaviors.
Intelligent control systems
Intelligent control systems are composed of controllers and computers that have the ability to learn, reason, and adapt to the manufacturing system. They use artificial intelligence and machine learning techniques such as neural networks, fuzzy logic, genetic algorithms, or reinforcement learning to model, analyze, and optimize the behavior of the manufacturing system. They can also interact with human operators or experts to acquire knowledge or feedback.
Intelligent control systems can provide a high degree of autonomy, flexibility, and robustness. They can also handle nonlinear and complex manufacturing systems. However, they can also suffer from computational complexity, data quality, or interpretability issues. They can also raise ethical or social concerns.
Applications of Computer Control of Manufacturing Systems
Computer control systems have been applied to various industries and domains that involve manufacturing processes. Some of the examples are:
Computer control systems are used to control and coordinate the production of vehicles and their components such as engines, transmissions, brakes, or airbags. They are also used to monitor and regulate the performance, safety, and efficiency of vehicles and their subsystems such as navigation, entertainment, or collision avoidance.
and control of aircraft and spacecraft and their subsystems such as engines, avionics, or payloads.
Computer control systems are used to control and coordinate the production of medical devices and equipment such as pacemakers, ventilators, or MRI scanners. They are also used to monitor and regulate the diagnosis, treatment, and rehabilitation of patients and their physiological functions such as blood pressure, heart rate, or glucose level.
Future Trends of Computer Control of Manufacturing Systems
Computer control systems are constantly evolving and improving to meet the changing needs and challenges of manufacturing systems. Some of the future trends of computer control systems are:
