A manufacturing system includes four different components: the production machine, material handling system, computer control system, and human resources (Lee, 1998). In recent times, due to technological advancement, automation of manufacturing systems has continued to become prevalent. A key aspect of contemporary automotive manufacturing systems and automotive industries is automation. An automated manufacturing system refers to an interconnected system of material processing stations with the capability of automatically processing an extensive range of part types simultaneously under computer control. The system is not only interlinked by a material transport system but also interconnected by a communication network for integrating all aspects of manufacturing. This type of system demonstrates flexibility in handling, routing, processes, and tool changes. An automated manufacturing system also exhibits key features including a high degree of automation, integration, and flexibility (Swamidass, 2000). This paper examines the four different components of a manufacturing system and provides a comprehensive discussion of the future of the automotive industry and automotive manufacturing systems.
A manufacturing system is defined as a set of integrated equipment and human resources that perform one or more processing and assembly operations on a starting work material, components, or set of components. The integrated equipment comprises production machines, material handling and positioning instruments, and computer systems. Within this automotive system, human resources are required either part-time or full-time to ensure that the equipment continues operating. Automation within the automotive industry refers to the use of control systems—such as robotics and computers—as well as information technologies for managing various processes and machinery within an industry to replace or supplement human operators (Groover, 2007).
In the contemporary setting, there is progressively more automation in automotive systems and industries as a whole. Initially, the objective of automation was to increase productivity and decrease costs associated with human system operators. Today, however, the emphasis has shifted toward increasing quality levels and flexibility within manufacturing systems. Specifically, automation minimizes errors linked to human beings. Unlike human workers, robots and machines do not experience fatigue, which results in products of consistent and uniform quality produced at any time (Joshi et al., 2018). Through automation, programming of robotics can enable the execution of virtually any task, making the manufacturing process more flexible. Automation also facilitates higher information precision and improved safety. Industrial automation can make the production line significantly safer for personnel by deploying robots to handle hazardous situations. Additionally, incorporating automated data collection enables firms to gather key manufacturing information, improve data accuracy, and reduce data-gathering expenses (Lamb, 2013).
Most manufacturing processes in automotive manufacturing systems are carried out by machines in some form. The categorization of machines according to the level of worker involvement is grouped into three classifications: manually-operated, semi-automated, or fully automated. In the present day, driven by increased automation and computerization, production machines tend to be either semi-automated or completely automated (O'Sullivan, 2009). Semi-automated machines perform a portion of the work process cycle under computerized control, after which an employee takes over for the remaining phases. For instance, a computer numerical control (CNC) lathe machine performs its processing operation according to an automated program, and then the employee is required to unload and reload the machine for the next work cycle. The employee must attend to the machine during every work cycle, though they do not need to be continuously present (O'Sullivan, 2009). Fully automated production machines are those capable of operating without any human involvement for periods longer than a single work cycle. Some form of machine attention and maintenance is still required periodically—for example, reloading the machine with raw materials. In the automotive industry, production machines provide key advantages, including automated assembly systems, gauging and measuring, feeding of automated parts, and inspection systems.
Over the past several decades, automation in manufacturing systems has transformed factory floors, manufacturing employment, and the economics of numerous manufacturing sectors. Today, production machines stand at the threshold of a new automation era defined by rapid advances in robotics, machine learning, and artificial intelligence—all of which enable machines to equal or surpass humans in a variety of work activities. Contemporary technological developments have overcome many traditional limitations of robotics and automation. A new generation of robots that are more flexible, multipurpose, and considerably less expensive than those currently used in many manufacturing settings can be trained by frontline workers to perform tasks previously considered too difficult for machines—such as collecting and storing irregularly spaced items or resolving complex electrical wiring issues in large-scale projects. The advancement of artificial intelligence is also creating significant progress that expands the potential for automating work tasks across numerous industries (Chui et al., 2017).
A material handling system within a manufacturing system encompasses an integrated system involving the controlling, handling, and storing of materials. The primary aim of material handling within a manufacturing system is to ensure that the correct amount of material is delivered safely to the appropriate destination at the right time and at the lowest possible cost (Tanchoco, 2012). Material handling is designed to minimize costs, ensure compatibility with other components and equipment in the manufacturing system, and satisfy safety requirements. Overall, material handling accounts for the movement, safety, storage, and control of materials and products throughout manufacturing, warehousing, delivery, consumption, and disposal processes (Krar and Gill, 2003).
How materials travel through a manufacturing facility directly influences production costs. Recognizing its significance, more firms are seeking ways to leverage technology to improve the material handling process. Material handling encompasses a remarkably broad range of applications; key equipment includes palletizers, conveyors, and sorters for manufacturing, bulk handling, warehousing, and distribution. The efficiency and reliability of material handling automation systems largely determine the productivity and cost-effectiveness of a distribution center or warehouse. In today's automated industrial environment, manufacturers strive to produce and ship products to consumers quickly and cost-effectively while maintaining high quality.
Over approximately seven decades, material handling in the automotive industry has undergone significant changes, from assembly lines operated entirely by individual personnel to contemporary assembly lines featuring material handling machines and robots. Advances in material handling are following similar trends driven by automation. The automotive industry faces challenges that include overcapacity and market saturation, mounting variability between vehicle models driven by shorter time-to-market demands, global competition, and a constantly changing regulatory environment. These challenges are being addressed through innovations in flexible production and manufacturing, continuous digital process chains, and advances in big data and artificial intelligence for smart industrial units that provide engineers and managers with complete transparency into manufacturing and logistics (Hanke, 2017).
Smart manufacturing, together with material handling, goes beyond diagnostics carried out by a single machine. It capitalizes on combined big data and delivers real business insight to automotive manufacturers and original equipment manufacturers on how to improve systems both as a whole and at the individual component level. Present-day automotive industries are entering a new era—one dependent on smart factories—which requires a significantly different approach to material-handling equipment and systems. Key aspects of material handling in today's automotive industries include the following.
Present-day assembly lines are based on either linear or modular production and rely on machines that are rigid and designed for a single purpose. However, the design of vehicles and what consumers expect is changing. Automotive industry players that aim to be agile will require flexible material handling equipment. A new combination of automated transport systems—such as automated guided vehicles for material flow and mobile tool carriers—will place greater demands on logistics controls. The growing number of autonomous vehicles also necessitates new safety features (Hanke, 2017).
Nearly every new manufacturing or assembly design in the automotive industry is supported by a simulation. Material handling components play a major role in simulating everything from complete factories to individual automotive processes, since they put parts, fasteners, and finished products into play. Requests for behavior models for all components in material-handling systems are increasing rapidly. Good simulation provides rapid insights into time and labor requirements, quality levels, and total process costs (Hanke, 2017).
There are numerous categories of material handling systems used in manufacturing. The automation and innovation employed within each can differ, yet can also overlap. The three broad types of systems among the most impactful in automated manufacturing include engineered systems, industrial trucks, and storage and handling equipment.
Within an automated manufacturing system, storage equipment functions as a system that facilitates keeping materials until they are ready to be picked or transferred to another destination. There are numerous ways of moving raw materials, works in progress, and finished goods within a warehouse. Although manual material handling operations may still be necessary in some cases, many organizations are shifting toward automated solutions to achieve greater speeds, improved safety, and more efficient operations (Otto Motors, 2018).
Engineered systems typically consist of a set of instruments, devices, or machines that perform material handling tasks in an automated manner—such as storing and retrieving materials. Within an automated manufacturing system, this makes it possible to integrate other material handling equipment and infrastructure, such as racks and shelving, where manufactured products are stored. Because of automation, machines employing artificial intelligence are central to this process and include self-driving machines. These machines enable manufacturing firms to create both flexible and adaptable flows of materials within their operations. Furthermore, when integrated with advances such as the Internet of Things, these machines facilitate improved flow of inventory data and critical production information that enables the facility as a whole to function more effectively (O'Grady, 2012).
In material handling, industrial trucks serve the primary purpose of moving materials or finished products around a manufacturing facility. Like simple equipment such as lifts and carts, industrial trucks can also be powerful and complex machines. Due to technological advancement, these processes are becoming progressively more streamlined. Many manufacturing firms are testing wearable exoskeletons that personnel can use to assist with everyday tasks. Given the mounting demand for greater speed and personalization in automated manufacturing systems, and the natural physical limitations of individual workers, this form of automation enables firms to gain a competitive advantage (Nicholas, 2015).
