✔ Robots – Industrial robots for assembly, welding, material handling, and other tasks.
✔ AGVs (Automated Guided Vehicles) – Self-guided vehicles used for material transport within a factory.
✔ Sensors & IoT Devices – Used for real-time monitoring and data collection.
✔ Central Computer System – Controls and coordinates all automated systems.
1.3 Advantages of Integration
✅ Increased Productivity – Machines work together without delays.
✅ Higher Precision & Accuracy – Automated systems minimize human errors.
✅ Reduced Labor Costs – Less manual intervention required.
✅ Efficient Resource Utilization – Better material handling and production flow.
2. Computer-Aided Quality Control (CAQC)
2.1 What is CAQC?
Computer-Aided Quality Control (CAQC) is the use of computer systems, sensors, and software to monitor, inspect, and control the quality of products in a manufacturing process.
2.2 Methods Used in CAQC
✔ Automated Inspection – Use of vision systems, laser scanners, and CMM (Coordinate Measuring Machines) to inspect products.
✔ Statistical Process Control (SPC) – Uses statistical data to detect variations in production.
✔ Real-Time Quality Monitoring – Sensors continuously check for defects.
✔ Data Analysis & Reports – Generates quality control reports for analysis.
2.3 Benefits of CAQC
✅ Reduces Defective Products – Ensures quality standards are met.
✅ Speeds Up Quality Checks – Automated systems inspect products faster than humans.
✅ Enhances Consistency – Standardized inspections reduce variation.
✅ Lowers Production Costs – Minimizes waste and rework.
3. Business Functions in Computer Integrated Manufacturing (CIM)
3.1 What are Business Functions?
Business functions in Computer Integrated Manufacturing (CIM) include activities related to planning, management, and decision-making in a manufacturing environment.
3.2 Key Business Functions in CIM
✔ Production Planning & Scheduling – Determines the production sequence and timelines.
✔ Inventory Management – Ensures raw materials and finished products are available when needed.
✔ Supply Chain & Logistics – Manages the transportation of materials and products.
✔ Cost Estimation & Budgeting – Calculates manufacturing costs and optimizes expenses.
✔ Customer Order Processing – Automates order tracking and fulfillment.
3.3 Advantages of CIM in Business Functions
✅ Improved Decision Making – Real-time data helps managers make better decisions.
✅ Cost Savings – Optimized planning reduces waste and unnecessary expenses.
✅ Faster Production – Automated scheduling speeds up manufacturing.
4. Computer-Aided Forecasting
4.1 What is Computer-Aided Forecasting?
Computer-Aided Forecasting involves the use of software and data analysis techniques to predict future trends in production, sales, and inventory requirements.
4.2 Methods of Forecasting
✔ Time-Series Analysis – Uses past data to predict future trends.
✔ Machine Learning Algorithms – AI-based forecasting for more accuracy.
✔ Simulation Models – Computer-generated models to analyze future production needs.
4.3 Benefits of Computer-Aided Forecasting
✅ Better Inventory Management – Ensures stock availability without overstocking.
✅ Optimized Production Planning – Prevents delays by predicting material requirements.
✅ Improved Business Strategies – Helps companies plan for future demands.
5. Office Automation
5.1 What is Office Automation?
Office automation refers to the use of computer systems and software to streamline business processes, improve communication, and increase productivity in an organization.
5.2 Components of Office Automation
✔ Electronic Document Management – Digital storage of documents to reduce paperwork.
✔ Communication Systems – Emails, video conferencing, and messaging platforms.
✔ Enterprise Resource Planning (ERP) Systems – Integrates business processes like HR, finance, and supply chain.
✔ Automated Data Processing – Software for financial calculations, payroll, and reporting.
5.3 Benefits of Office Automation
✅ Increases Efficiency – Reduces manual work and saves time.
✅ Enhances Communication – Quick and effective information sharing.
✅ Reduces Costs – Less dependency on paper-based systems.
6. Conclusion
