- Quality must be ensured.
Integrated Manufacturing Systems
- Computer-Integrated Manufacturing Systems (CIMSs):
- Integration of hardware, software, database management, and communications.
- Automates and controls production activities.
- Numerical Control (NC):
- A programmable device that controls tool movements to duplicate a machinist’s skills for making complex shapes.
- Computer Numerical Control (CNC) Machines:
- NC machines driven by a computer.
Computer-Aided Design and Manufacturing
- Integrated manufacturing systems emerged with:
- Computer-Aided Design/Computer-Aided Engineering (CAD/CAE): Enables engineers to design, analyze, test, simulate, and "manufacture" products before they are physically made.
- Ensures a product can be manufactured to specifications when released to the shop floor.
- Computer-Aided Manufacturing (CAM): Computer control of the manufacturing process.
- Determines machine tool movements and optimizes cutting speeds.
Flexible Manufacturing Systems
- Flexible Manufacturing Systems (FMSs):
- Two or more computer-controlled machines or robots linked by automated handling devices (e.g., transfer machines, conveyors, transport systems).
- Computers:
- Direct the overall sequence of operations.
- Route work to appropriate machines.
- Select and load proper tools.
- Control machine operations.
- Integration:
- Many companies have successfully integrated CAD/CAE, CAM, and FMSs into CIMSs.
CIMS Facts and Advances in OM Technology
- According to the National Research Council (NRC), companies with CIMS experience have been able to:
- Decrease engineering design costs by up to 30%.

- Advances of technology in OM also include:
- Three-dimensional printing, technically called additive manufacturing.
- Nanotechnology applications in computer processing and memory cards.
Robotics and Smart Factories
- Robot:
- A programmable machine designed to handle materials or tools in performing various tasks.
- Industrial robots can be "taught" many sequences of motions and operations and can even learn to make certain logical decisions.
- Autonomous robots (including drones) have sensors that allow them to perform their tasks while staying out of the way of people or equipment.
- Smart Factory:
- A digitized manufacturing facility that uses connected devices, machinery, and production systems to collect and share data continuously.
- Smart factories improve productivity by providing more flexibility and agility to manufacturing.
Service Technology
- Technology in Services:
- Used in downloading music, banking, automated car washes, voice recognition in telephone menus, medical procedures, hotel and airline kiosks, and entertainment.
- Used behind the scenes in hotels, airlines, hospitals, and retail stores to facilitate service experiences.
- E-service:
- Using the Internet and technology to provide services that create and deliver time, place, information, entertainment, and exchange value to customers and/or support the sale of goods.
Technology in Value Chains
- Business analytics:
- Plays a critical role in managing value chains.
- Integrates and analyzes data throughout the value chain within an information systems framework.
- Customer Relationship Management (CRM):
- A business strategy to learn more about customers’ wants, needs, and behaviors.
- Aims to build customer relationships and loyalty; and ultimately enhance revenues and profit.
- Includes: market segmentation and analysis, customer service, customer relationship building, effective complaint resolution, cross-selling of goods and services, preproduction order processing, postproduction field service.
CRM Benefits
- CRM helps firms gain and maintain a competitive advantage by:
- Segmenting markets.
- Tracking sales trends and advertising effectiveness.
- Identifying the focus of targeted marketing initiatives.
- Forecasting customer retention (and defection) rates.
- Identifying which transactions are likely to be fraudulent.
- Studying the optimal bundling of goods and services.
- Studying and predicting the most attractive Web characteristics.
- Linking the previous information to competitive priorities by market segment and process.

- Benefits:
- Creates new industries and job opportunities.
- Restructures old and less productive industries.
- Integrates supply and value chain players.
- Increases marketplace competitiveness and maintains the survival of the firm.
- Provides the capability to focus on smaller target market segments through mass customization.
- Improves/increases productivity, quality, customer satisfaction, speed, safety, and flexibility/customization.
- Lowers cost.
- Raises world's standard of living.
- Monitors environment and health of the planet.

Technology Decisions and Implementation
- Sociotechnical System:
- The interaction of technology, people, and processes.
- Scalability:
- Related to the contribution margin (unit revenue – unit variable cost) required to deliver a good or service as the business volume increases.
- High scalability: Capability to serve additional customers at zero or extremely low incremental costs.
- Low scalability: Serving additional customers requires high incremental variable costs.
Analytical Methods for Technology Decisions
- Analytical methods based on data can provide more informed decisions, particularly when economics plays a key role.
- Decision Analysis for Technology Decisions:
- The formal study of how people make decisions, particularly when faced with uncertain information, and a collection of techniques to support the analysis of decision problems.
- Break-Even Analysis for Technology Decisions:
- Used to analyze profit or loss or to make an economical choice between two options that vary with volume.
Making a Technology Choice Decision
- Problem 4.1 Example:
- Maling Manufacturing must choose between purchasing a conventional machine or an automated machine.
- Profitability depends on demand (Low vs. High).
- Solution:
- Maximax decision: Choose the option with the maximum possible profit (d2).
- Maximin decision: Choose the option with the maximum minimum profit (d1).
- Minimax regret decision: Choose the option that minimizes the maximum opportunity loss (d2).
Making a Technology Choice Decision with Event Probabilities
- Problem 4.2 Example:
- Maling Manufacturing estimated a 0.6 probability of low demand and a 0.4 probability of high demand.
- Solution:
- The expected profits for the individual choices of machines are (1) = 0.6($15) + 0.4($21) = $17,400 and (2) = 0.6($9) + 0.4($35) = $19,400.
- Because EV(d2) is higher, the best decision based on EV is the automated machine.
- EVPI (Expected Value of Perfect Information):
- = (2) = 0.6($6,000) + 0.4(0) = $3,600
Decisions Using Break-Even Analysis
- Problem 4.3 Example:
- Maling Manufacturing can purchase an automated machine from either vendor A or vendor B.
- Vendor A: Fixed cost (FCA) = 85,000, Unit Cost (CA) = 3.50
- Vendor B: Fixed cost (FCB) = 60,000, Unit Cost (CB) = 5.00
- Solution:
- The total cost of the machine over its life is represented by the equation: Total\, cost\,(TC) = Fixed\, cost\,(FC) + Unit\, cost\,(C) \times Quantity\,(Q)
- Vendor A: TC_A = $85,000 + $3.50 \times Q
- Vendor B: TC_B = $60,000 + $5.00 \times Q
- Break even point is the Quantity, Q, such that TCA = TCB . Thus:
TCA(Q^) = TCB(Q^)
85,000 + $3.50Q^ = $60,000 + $5.00Q^
85,000 - $60,000 = ($5.00 - $3.50)Q^
25,000 = $1.50Q^
Q^ = \frac{25000}{1.5} = 16,667
Because 20,000 units exceeds Q*, Maling should purchase from vendor A.
