State its objectives. Differentiate between product layout and process layout. ## Short answer Plant layout arranges machines and facilities for smooth flow, minimal handling, and effective space use. Product layout arranges machines in operation sequence for high-volume standard products (low flexibility, low WIP). Process layout groups similar machines for varied, low-volume jobs (high flexibility, high WIP). ## Answer **Plant layout** is the arrangement of machines, equipment, storage, service areas and workers in a plant so that the production process runs smoothly at minimum cost. It is the physical arrangement of facilities to give the best use of space, labour and machines. #### Objectives - Minimum material handling and transport distance. - Smooth, continuous flow with no back-tracking. - Effective use of floor space and equipment. - Safe, comfortable working conditions. - Flexibility for changes in product or volume. - Easy supervision and communication, and lower work-in-process. #### Product (line) layout Machines are arranged in the sequence of operations of one product, as in an assembly line or bottling plant. #### Process (functional) layout Similar machines or functions are grouped together (lathe section, milling section, grinding section) and jobs move between sections, as in a job shop. | Basis | Product layout | Process layout | |---|---|---| | Arrangement | By sequence of operations | By type of machine/function | | Product volume | High, standard | Low, varied (job or batch) | | Machines | Special-purpose | General-purpose | | Material handling | Mechanised, short, fixed path | Varied paths, more handling | | Work-in-process | Low | High | | Flexibility | Low | High | | Machine utilisation | High if balanced | Moderate, often low | | Labour skill | Low to medium | High | | Investment | High | Lower | | Breakdown effect | Stops the whole line | Affects only one job | | Production control | Simple | Complex | #### Examples - Product layout: car assembly, soft-drink bottling, sugar plant. - Process layout: machine shop, hospital, repair workshop. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. What is plant layout? A. Choosing the city for a factory B. Arrangement of machines, equipment, storage and workers so the process runs smoothly at minimum cost C. Scheduling of jobs on a Gantt chart D. Selection of the factory roof type Answer: B. Plant layout is the physical arrangement of facilities for the best use of space, labour and machines. (Key point: Plant layout) 2. How are machines arranged in a product layout? A. By type of machine B. Around a fixed product C. In the sequence of operations of one product D. Randomly Answer: C. Product layout follows the sequence of operations, as in an assembly line or bottling plant. (Key point: Product layout arrangement) 3. Which statement is correct? A. Process layout suits high-volume standard products B. Product layout has high flexibility C. Product layout uses general-purpose machines D. Process layout suits low-volume varied jobs and has high flexibility Answer: D. Process layout groups similar machines for job or batch work and is flexible; product layout is for high volume with low flexibility. (Key point: Volume and flexibility) 4. What is the effect of a machine breakdown in product layout compared with process layout? A. It stops the whole line, while in process layout it affects only one job B. It affects only one job, while in process layout it stops all C. No effect in either D. It stops the line in both Answer: A. Product layout is a connected line so a breakdown stops it; in process layout other jobs can continue. (Key point: Breakdown effect) ## Related in Industrial Engineering and Management - [Flow patterns in plant layout](https://www.bctengineer.com/question.md?key=semester_6%2Findustrial_engineering_and_management%3Aflow-patterns-in-production-layout) — Industrial Engineering and Management, chapter 2 - [From-to chart load-distance layout comparison](https://www.bctengineer.com/question.md?key=semester_6%2Findustrial_engineering_and_management%3Aload-distance-from-to-chart-layout) — Industrial Engineering and Management, chapter 2 ## Related in other subjects - [Reheater in steam plant with layout](https://www.bctengineer.com/question.md?key=semester_7%2Fpower_plant_equipment%3Asteam-reheater-layout) — Power Plant Equipment, chapter 7 - [Development cycle; storage plant layout](https://www.bctengineer.com/question.md?key=semester_7%2Fhydropower_engineering%3Adev-cycle-storage-layout) — Hydropower Engineering, chapter 2 - [Product and service design process](https://www.bctengineer.com/question.md?key=semester_7%2Fentrepreneurship_development%3Aproduct-service-design-process) — Entrepreneurship Development, chapter 2 - [Layout of diesel power plant](https://www.bctengineer.com/question.md?key=semester_7%2Fpower_plant_equipment%3Adiesel-plant-layout) — Power Plant Equipment, chapter 5, asked 3×
