Study Notes
Manufacturing Operations
- Manufacturing is the process of using physical and chemical processes to alter materials to create parts and products.
- Manufacturing transforms raw materials into items of higher value through processing and assembly.
- Manufacturing operations involve machinery, tools, power, and manual labor.
Objectives
- Students will be able to describe the differences between discrete and process manufacturing.
- Students need to be able to explain the mathematical model of the relationship between product and production.
- Students will learn to perform calculations and analyses of production systems based on mathematical models.
- Students will be able to perform cost analysis on manufacturing operations.
Manufacturing Defined - Technological Definition
- The application of physical and chemical processes changes the geometry, properties, and appearance of a starting material, creating parts and products.
- Multiple parts are joined to create assembled products.
- Manufacturing is generally a series of operations.
- It's achieved via a combination of machinery, tools, power, and manual labor.
Manufacturing Defined - Economic Definition
- The conversion of materials into more valuable items by using one or more processing and assembly operations adds value to the material.
- Examples include converting iron ore to steel, transforming sand into glass, or refining petroleum into plastic.
Manufacturing Industries and Products
- Primary Industries: These industries cultivate and utilize natural resources such as mining, petroleum, and agriculture.
- Secondary Industries: These industries transform the output from primary industries into products like cars, computers, and consumer appliances.
- Tertiary Industries: These industries provide services, such as hotels, legal services, finance, and banking.
More Industry Classifications
- Process Industries: These industries focus on continuous production, including chemicals, petroleum, basic metals, foods, and beverages, and power generation.
- Discrete Product Industries: These industries focus on creating individual products like cars, aircraft, appliances, machinery, and their component parts. This production is often done in batches.
Process vs. Discrete Manufacturing
- Process manufacturing includes chemical, pharmaceutical, and petroleum industries.
- Discrete manufacturing includes cars, hand phones, and computers.
Classifications of Manufacturing Processes
- Processing operations use energy to transform materials from one state of completion to a more advanced state closer to the final desired product.
- Assembly operations combine two or more components to form a new entity, including assemblies, sub-assemblies, and joined parts.
Production System
- Manufacturing Processes and Assembly Operation: Manufacturing systems utilize automation or manual methods, including cells, machine tools, robotics, and group technology.
- Material Handling and Storage: This involves the movement and storage of materials between processing and/or assembly stages.
- Automation and Control Technologies: This is the regulation and control of automated operations, machines, and processes.
- Manufacturing Support Systems: This includes manufacturing engineering to optimize processes and quality; production planning and control to manage logistics and capacity; and quality control to ensure products meet standards.
- Quality Control System: This involves quality control, inspection to ensure final products adhere to specifications.
Overview of Production System
- A hierarchical structure exists for production systems, from an enterprise level to a factory-level and finally, to the actual manufacturing process itself. This includes manufacturing support systems, quality control, and facilities.
Plant layout -Types
- Fixed-Position Layout: The product remains in a fixed location throughout the entire production process. Workers and equipment move around the product.
- Process Layout: Equipment is grouped by function or type. Work moves between departments or work units sequentially, based on the required process steps.
- Product-Oriented Layout: Equipment arranged sequentially based on production processes. Work passes through the equipment in a linear fashion. Work units operate on specific sections of the the manufacturing process.
- Cellular Layout: This layout groups related machines or workstations into cells to produce a limited variety of parts or products. The layout of similar equipment allows for efficient batch processing and reduces the amount of moving parts.
Production Facilities
- There is a relationship between production quantity and product variety.
- Low production: 1-100 units
- Medium production: 100-10,000 units
- High production: 10,000 - 1 million units
Product / Production Relationships
- A quantitative method for determining how manufacturing operations are organized.
- Product Quantity (Q): Total output from the plant
- Product Variety (P): Different types of products manufactured
- Complexity of assembled product (n): Number of parts
- Examples of products and components include mechanical pencils, bicycles, cars, commercial planes, and space shuttles.
- Additional factors affect production include the number of operations and the variety within a product line.
Mathematical Model
- A quantitative method of determining the organization of manufacturing operations.
- Q = product quantity
- Qj = Total quantity of style j
- Qf = Total quantity for all styles
- P = Total number of product variety/style
Example Problem
- Companies plan for new product lines and new factories.
- Annual production and the number of components for each product are considered.
- Key factors in production operations include processing steps, processing times, and the required worker(s).
In-Class Exercise
- A plant produces three product lines (A, B, and C).
- Six models within product line A, four within B, and eight within C.
- Average annual production quantities for each model are given.
- The values of P(product variety) and Qf (total output from plant) for the plant need to be determined.
