Topic 7 - Facility Layout Design
Question | Answer |
---|---|
what is facility layout design? | determines the best disposition of different elements of process so fixed goals are achieved adequately and effectively |
state the 6 types of material flow? | 1. Toothed 2. Line 3. S 4. O 5. U 6. L |
what are the main objectives of layout design? | - workers security - optimal labour/machinery - staff satisfaction - supervision & control - changing conditions - reduce congestion - reduce delays - reduce material |
what factors need to be considered for layout design? | - flow of materials - equipment and dimensions - labour security - secondary services - building limitations |
what are 3 types of distribution? | 1. product = production line to outputs 2. process = input, cutting, assembling, output 3. hybrid (cellular) = efficient & flexible, personnel & machinery grouped (eg cell A, cell B) |
what are the types of layout in the industry sector? | 1. Mono-linear industries = unique circuit, always same 2. synthetic/convergent = many materials, one product 3. analytical/divergent = one material, many diff products 4. convergent-divergent = several materials, one middle, several products |
what are the types of layout in a production organisation? | 1. fixed position layout = large units, hard to move 2. assembly line = work units one after other, follow order 3. line = work centres in chains, need previous pieces of family, tooling changed rapidly 4. functional = work centres grouped by activity |
state pros & cons of fixed position layout | pro - low handing of mounting unit con - space required - need materials, machinery & subcontractors to move to production site |
state pros & cons of assembly line layout | pros - reduce orders in progress - reduce delivery time cons - need big lots - rigid planning - work balancing is difficult |
state pros & cons of line layout | pros - low orders in progress - minimal transport - easy planning & control - operators NOT specialised cons - inflexible (repetitive) - prone to breakdown - high investment |
state pros & cons of functional layout | pros - flexible - low investment - easier to maintain - task diversity = satisfaction cons - high volume - high unit costs - low productivity - expensive to maintain - difficult planning & control - longer delivery terms |
what is a ficticious range? | find adequate location of work stations so can adapt to all production flows |
what is the layout for: a) services b) offices | a) direct customer contact, customer satisfaction, attractive appearance b) materials = information, distribution = workers & documents |
what is the distribution for: a) shops b) warehouses | a) maximise net profit, exhibition of products to clients, distribution = exhibit as many products as possible in available space b) optimal ratio between handling costs of materials and storage space, computers ease locating articles in warehouse |
