use of computer systems 1.6 Flashcards
what is Just in time?
a stock control management system that depends highly on integrated computer systems- materials and components are ordered in as they are needed
how are products and stock tracked in JIT?
using barcodes, which gives manufacturers access to up-to-date stock information
what are the advantages of JIT?
- materials and energy from being wasted on unwanted products
- fewer workers/operators need to be employed which saves money on wages as the production line is not continuously running
-enables high-street fashion stores to react to consumer demands and fashion trends, enabling them to remain competitive
-no stock room required- saves on warehousing costs
-stock doesn’t become obsolete, damaged or deterioated
what are the disadvantages of JIT?
-the system depends highly on suppliers and transport infrastructure- if a fabric/component is delivered late it could slow down the whole process
-reliant on a high quality supply chain
-fewer benefits from bulk purchasing e.g discounts
what is modular/cell production?
workers operate in small teams to enable products to be made
what is a flexible manufacturing system?
a flexible manufacturing system, just like quick-response manufacturing is able to respond quickly to market demand. FMS uses ‘demand activated manufacture’ meaning that the products are manufactured after a consumer purchases them, basing their manufacture from demand
what does JIT entirely depend on?
a barcode system- barcodes are attached to every product and are read using scanners at each stage of manufacture- this allows manufacturers to place orders for components or materials quickly
what are the advantages of flexible manufacturing systems?
-can readily adapt to changes in the type and quantity of good being produced- allow for quick response to changes and consumer demand
-FMS is largely computer automated, reducing overall labour costs
-allows for customised products
-keeps inventories low
-avoids/reduces wastage- products are manufactured when they are ordered by a customer
what are the disadvantages of flexible manufacturing systems?
-the systems are more expensive to design and initially costly to install- requires skilled technicians
what does PPC stand for?
production, planning and control
what does CAM stand for?
Computer aided manufacture
what does CAM include?
-manufacturing processes e.g:
-fabric manufacture and printing
-cutting
-sewing
-pressing
what does CAD stand for?
Computer aided design
what does CAD include?
-virtual modelling
-colourways
-PDS software
-draft patterns
-grade patterns
-produce lay patterns
what does CAA stand for?
Computer automated administration
what does CAA include?
-marketing and sales
-accounting and costing
-processing orders
-stock administration and buying
what does CIM stand for?
computer intergrated manufacture
what does EDI stand for?
Electronic data interchange
what are standardised components?
components such as zips, bias binding etc which come in pre-set sizes and are mostly brought in from specialised manufacturers.
what are the advantages of standardised components?
-there is a wide range to choose from
-components can be brought in bulk to reduce unit cost
-JIT stock control systems can buy components as and when needed
-there is no need to invest in machinery to make components
what is sub-assembly?
where individual parts/ groups of parts are brought together to form a finished product- some parts of the product can be made as a separate line of manufacture e.g shirt collars or sleeves. the sub-assembled parts are then fed into the main production line at the appropriate stage of manufacture.
what are the advantages of sub-assembly?
- the sub-assembly lines do not have to be in the same factory or operated by the same manufacturer
- can improve product quality and simplify and speed up the manufacturing process
- Sub-assembly facilitates JIT manufacture and product parts can be brought in as needed
- Sub-assembly can be used for parts of the product which require specialist machinery
what is global production?
Garments/products can be designed in one country and manufactured in another. The designers and manufacturers can easily exchange information and communicate via the internet and computer- generated information can be sent to a manufacturer where it can be fed directly from the computer into computer automated machinery
what are the advantages of global production?
- The internet has made it incredibly easy to exchange information and computer- generated information via the internet
- manufacture is often cheaper in other countries in continents such as Asia- labour costs are often cheap which makes the garment cheaper
