Strategues To Optimise Operations Flashcards
3 Facilities Design and Layout Strategies
Fixed position layout
Product layout
Process layout
Fixed position layout examples
Fixed position layout deals with large scale processes, such as the construction of bridges, ships, aircraft, or buildings. With thus layout it is mor efficient to bring inputs to the site, this means workers and equipment come to work in the same area. Boeing constructs its airplanes using a fixed position layout, all the inputs are brought to one warehouse area where the airplanes are constructed.
2 advantages of fixed position layout
Workers and equipment are all in one area thus increasing efficiency as there is no need for workers and equipment moving around which would take time and decrease productivity.
It is best when it is more appropriate to bring all the inputs into one location, an example is the construction of airplanes as the good is so large it would be difficult to move it as it is being produced therefore it makes sense to bring the inputs to it as it is being constructed.
One disadvantage of fixed position
It is difficult to store the materials, as it is difficult to find space for them to be stored safely.
Product layout, examples
Deals with the manufacturing of goods in mass volume, using an assembly line. This strategy increases productivity to manufacture goods efficiently and effectively as the good moves through an assembly line where different processes can be carried out as it moves through without interruption from other processes, it is very quick because of this. Yakult uses a product layout as they mass produce a standardised product (a drink) that can be produced using an assembly line.
2 advantages of a product layout
Efficient as it is quick to move products through an assembly line which also enables large levels of production.
Less labour is required due to many assembly lines being carried out by technology such as robotics which can cut costs as less employees are required.
2 negatives of a product layout
Expensive to set up as assembly lines often rely on expensive technology.
If there is a problem on the assembly line it can cause the whole factory to shut down, if a factory relies on one assembly line and one of the products being produced has an issue on the line, the whole line may need to be halted which decreases productivity.
Process layout, examples
Equipment and work centres are arranged according to similarity of function. McDonald’s use this layout as for the output of a burger to be produced it needs to go through various stages of production at different areas including cooking meat, adding lettuce, presiding takeaway bag, the item needs to go through the various areas in a sequential order before it the service is completed or the good is ready.
2 advantages of a process layout.
It can be used to produce a wide variety of products as the goods/services are not being moved thorough one line, they are instead being moved into different necessary areas where processes can be carried out .
Breakdowns of machinery do not halt the entire production process as other areas are able to continue working.
2 disadvantages of a process layout
It is not recommended for standardised products as it would be more productive to use an assembly line for standardised products instead of taking the time to manually take the good in production to different areas which is much more time consuming.
It may also mean lower quality products as because the different areas have to be able to produce different types of products, eg different burgers, which means the processes can not be optimised to the specific details of one product they instead have to be suitable for many different goods/services, a grill can be used to cook both chicken and beef instead of being specialised to just meat.
4 materials management strategies
Inventory control
Materials planning, MPS, MRP
Just in time
Supply chain management
Inventory control EXAMPLES
A method of ensuring that costs are minimised and that an organisations operations system has access to the right amounts of inputs when required. Myer uses inventory control,as they manage the amount of inventory that they purchase from suppliers, and the amount they deliver to each store based on past sales figures that indicate the number of inputs needed, this saves costs on storage and still ensures that outputs can be produced efficiently.
2 Advantages of inventory control
Costs can be minimised by not allowing materials to remain idle and by making sure that inputs are available for the operations when needed.
A computerised inventory management system increases speed and efficiency of the LSO, as it is able to determine the amount of inputs required more accurately than a human.
2 disadvantages inventory control
Unexpected changes in stock needs can result in the running out of stock too soon because only the minimum amount needed was kept.
Inaccuracies during stocktake, either due to staff mistakes or computer error, can result in significant amounts of waste or shortages of stock.
Materials planning, MPS, MRS, EXAMPLE
The initial stages of operations planning involves the organisation establishing a production plan, which is an outline of the activities undertaken to to transform inputs to outputs.
A master production schedule contains the details of what is to be produced and when.
A materials requirements plan involves developing an itemised list of all materials involved in production to meet the specified orders.
Qantas would use a schedule and requirements planning to decide what types of food/drinks/other services need to be provided to customers and when.
2 advantages of mps
Timely delivery of manufactured goods to customers.
The right materials required for production at different times will always be available.
2 advantages of Mrp
The right resources will always be available and unneeded resources won’t be collected as the Mrp will have all the required resources listed.
This will also decrease waste as unnecessary resources that would have gone to waste will not be accidentally collected.
Just in time approach,
An approach that aims to avoid holding stock. Supplies arrive just as needed for production, and finished products are immediately dispatched or sold to customers.
