# Achieving World-Class Operations Management

## Transforming the Factory Floor with Technology

1. What roles do technology and automation play in manufacturing and service-industry operations management?
Technology is helping many firms improve their operating efficiency and ability to compete. Computer systems in particular are enabling manufacturers to automate factories in ways never before possible. Among the technologies helping to automate manufacturing are computer-aided design and manufacturing systems, robotics, flexible manufacturing systems, and computer-integrated manufacturing.

### Computer-Aided Design and Manufacturing Systems

Computers have transformed the design and manufacturing processes in many industries. In computer-aided design (CAD), computers are used to design and test new products and modify existing ones. Engineers use these systems to draw products and look at them from different angles. They can analyze the products, make changes, and test prototypes before manufacturing a single item. Computer-aided manufacturing (CAM) uses computers to develop and control the production process. These systems analyze the steps required to make the product, then automatically send instructions to the machines that do the work. CAD/CAM systems combine the advantages of CAD and CAM by integrating design, testing, and manufacturing control into one linked computer system. The system helps design the product, control the flow of resources needed to produce the product, and operate the production process. Companies can further improve the design and manufacturing processes through the use of additive manufacturing, commonly referred to as 3D printing.  Specialized printers can create products or parts for use in early prototypes, and some industries print certain components on site rather than shipping them.
Cardianove Inc., a Montreal-based manufacturer of medical and surgical equipment, used CAD software to develop the world’s smallest heart pump. The company says using computer-aided design shaved two years off the normal design time for cardiac devices. The company’s CAD program ran complex three-dimensional simulations to confirm that the design would function properly inside the human body. Using CAD software, Cardianove tested over 100 virtual prototypes before the top three designs were produced for real-life testing.

### Robotics

Robots are computer-controlled machines that can perform tasks independently. Robotics is the technology involved in designing, constructing, and operating robots. The first robot, or “steel-collar worker,” was used by General Motors in 1961. Robots can be mobile or fixed in one place. Fixed robots have an arm that moves and does what the computer instructs. Some robots are quite simple, with limited movement for a few tasks such as cutting sheet metal and spot welding. Others are complex, with hands or grippers that can be programmed to perform a series of movements. Some robots are even equipped with sensing devices for sight and touch.
Robots usually operate with little or no human intervention. Replacing human effort with robots is most effective for tasks requiring accuracy, speed, or strength. Although manufacturers such as Harley-Davidson are most likely to use robots, some service firms are also finding them useful. Hospitals, for example, may use robots to sort and process blood samples, freeing medical personnel from a tedious, sometimes hazardous, repetitive task.

### Adaptable Factories: Flexible and Computer-Integrated Manufacturing Systems

A flexible manufacturing system (FMS) automates a factory by blending computers, robots, machine tools, and materials-and-parts-handling machinery into an integrated system. These systems combine automated workstations with computer-controlled transportation devices. Automatic guided vehicles (AGV) move materials between workstations and into and out of the system.
Flexible manufacturing systems are expensive. But once in place, a system requires little labor to operate and provides consistent product quality. It can also be adjusted easily and inexpensively. FMS equipment can quickly be reprogrammed to perform a variety of jobs. These systems work well when small batches of a variety of products are required or when each product is made to individual customer specifications.
Computer-integrated manufacturing (CIM) combines computerized manufacturing processes (such as robots and flexible manufacturing systems) with other computerized systems that control design, inventory, production, and purchasing. With CIM, when a part is redesigned in the CAD system, the changes are quickly transmitted both to the machines producing the part and to all other departments that need to know about and plan for the change.

### Technology and Automation at Your Service

Manufacturers are not the only businesses benefiting from technology. Nonmanufacturing firms are also using automation to improve customer service and productivity. Banks now offer services to customers through automated teller machines (ATM), via automated telephone systems, and even over the internet. Retail stores of all kinds use point-of-sale (POS) terminals that track inventories, identify items that need to be reordered, and tell which products are selling well. Walmart, the leader in retailing automation, has its own satellite system connecting POS terminals directly to its distribution centers and headquarters.

### Summary of Learning Outcomes

1. What roles do technology and automation play in manufacturing and service-industry operations management?
Many firms are improving their operational efficiency by using technology to automate parts of production. Computer-aided design and manufacturing systems, for example, help design new products, control the flow of resources needed for production, and even operate much of the production process. By using robotics, human time and effort can be minimized. Factories are being automated by blending computers, robots, and machinery into flexible manufacturing systems that require less labor to operate. Service firms are automating operations too, using technology to cut labor costs and control quality.
