Q

Specification development?

A

Parameters defended using anthropometric data, material limitations and market research

Electronic information handling can be used in Specification development – in complex design can be used to define all parameters in the design and use all information e.g. anthropometric data, material limitations, component availability and sizes to establish specifications.
Reduces time and gives a big advantage in getting the product to market more quickly.

Design specification – set parameters of what is to be designed, most based on market research. Computer aided market analysis (CAMA) can be interrogated in a number of ways. Provide focus area for design spec.
Manufacturing specification – could be working scale drawings that have all the information required to manufacture the product. Computer Aided specification of Products (CASP) draws on artificial intelligence expert systems to suggest modifications and alterations to the design based on its knowledge of materials, available components, ease of assembly etc.

Q

Just in time?

A

Storing stock is both expensive (requires floor area to be stored) and is money sitting around doing nothing. If it is not being used to make a product it is not making profit.
Just in time relies on excellent communication with suppliers to ensure that stock to make the pro.

Reduces costs through efficiency
Only manufacturing when product is needed
New stock ordered when order level is reached
Less money tied up in raw materials

Increase efficiency – ethos is that stock not being used to produce goods is wasted money and not producing profit. Indeed, this stock requires space to store which means the building has to be larger and also this represents wasted money.
For this to happen – stock control has to be perfect, stock arrives as required and is ordered only as needed for a job. The stock and components also have to arrive at the correct stage in the manufacturing process. Not just as simple as all the stock turns up in one delivery. The bits have to make it to the right part of the production line. Entire factories can often be designed to met the movement of components around the assembly line.
Problems arise if the stock does not reach the plant on time – should a major accident hold up materials in a lorry on a motorway, the lack of materials can then be difficult to compensate for.
Generally turnover r is rapid and the factory has some flexibility in being able to produce more or less of a product easily.

Q

Production scheduling?

A

Sequences of tasks must be allocated correctly for efficient production
Computer based production makes process smooth and solves issues when they occur

In short ensuring the right components and the right bit of stock arrive on time and get to the right parts. This can get very complex on some designs – cars have thousands of components and computer modelling can be used to produce production schedules and model the most efficient way of getting materials around the factory floor. Also allows the company to work out in advance whether a delivery promise can be met, based on lead times and the likely modelled length of production.
It can also generate production plans for workers so the have complete understanding of the order of work and what should be done so that productivity is maximised.

Q

Production scheduling - ADVANTAGES?

A

Flexible - if quantities change
Raise productivity levels

Minimises work in progress and reduces inventory
Maintains balance on production lines

24
Q

Flexible manufacturing systems?

A

React to markets and make changes

A system set up to allow some flexibility in manufacturing. Usually to allow the company to respond to slight changes in market which allow it to fairly rapidly change parts of the manufacturing process.
For this to happen you need fairly hefty CAM systems which are linked to the machinery in the production cell. This enables the control of parts and material flow and as a result productivity should be better and lower down time with machinery.

How’s it work?
Form of flexible automation in which several machines are linked together by material handling system. Normally incorporates CNC , robotics automated material handling to form an integrated system. Not the same as a production line because it has the ability to process more than one product style simultaneously. Think of this as being a line that is capable of producing a Ford Fiesta as well as a Ford Focus and a Ford Ka as opposed to a production line which could only produce one.
Computing is sufficiently powerful to work out and coordinate not only the equipment but the order of processes as well which allows the line to alter and even change the manufacture of products to meet changes in demand. Allows some flexibility against unpredictability.

ADV
Production can be quickly altered allowing fast response to market changes / shorter lead times / increased market share.
• Smaller batches of products can be manufactured when needed reducing capital tied up in unsold stock.
• Products can be customized for individual consumers increasing the appeal / sales / profits from the product.
• Less reject components as FMS systems are able to check the quality of their own work.
• Integrated system of CNC machine linked by conveyor/automated guided vehicles/automated storage and retrieval systems
• Integrated computer system for planning and manufacturing reduces errors
• Flexibility in structure allows for quick changes in product production
• Increased productivity due to automation
• Lower labour costs due to automation
• Improved productivity due to removal of human error due to automation
• Faster/lower costs due to reduction in worker numbers
• Consistent quality due to automation
• Lower unit costs due to greater productivity when compared to same number of workers
• Less wastage
• Savings when compared to manual production due to little faults/reworking/rejects
• Better productivity due to automation and control eg 24/7 (manual production workers need breaks)
• Integrates with JIT thus reducing storage requirements
• Creates higher skilled technical jobs
• Flexibility of machines within the cell
• Production system can respond to market demand

DIS
Large capital investment needed for initial set up which would be off-set against minimal alteration costs when production is changed.
• Production rate could reduce on large batches due to CNC machines being slower than automated machinery.
• Staff would need retraining / new staff recruited as different skills are needed to operate the new equipment.
• Consideration of the downtime needed to install new systems is needed so that it is minimized / does not lead to financial problems.
• Expensive to set up
• Substantial planning required
• Complex/sophisticated manufacturing systems required
• Loss of manual skilled work
• Needs in-house technical support
• Set up of FMS may not be justified for simple tasks
• May have decreased productivity due to set up and machine set up downtime
• Maintenance ‘down time’ interrupts production
• High skilled technical jobs are a cost to the company

25

26
Q

Quick response manufacture - ADVANTAGES?

A

Reduce lead time of all aspects of manufacturing process
Allows to respond quickly to the making of products
Improves quality of final product and reduces cost

Designed to give companies a competitive edge by increasing operating efficiency. Have to move from batch production to flow production to achieve this. The flow is triggered by consumer demand rather than modelled forecasts of what might be bought. Allows manufacture to respond to market fluctuation.
How does it work?
Involves aspects of TQM, JIT and manufacturing cells. Aim is to increase over all flexibility and responsiveness. Manufacturing in cells with highly skilled production teams allows flexibility as the teams can be reallocated and swapped around to meet demand. More efficient than mass production which tends to be designed to take advantage of large economies of scale by producing large batches which can encourage stockpiling.
If working well should be like:
Order received by manufacturer
Production begins
Raw materials delivered by supplier directly to production line
Product made and then palletised and trucked out to customer.
Response entirely to demand – Market – pull materials through production line as quickly as possible.

27
Q

Production control - ADVANTAGES?

A
Measurable quality throughout
Speeds up inspection time
Issues instantly identified 
Large 3D objects tested

Information instantly transferred
28
Q

Production control?

A

Accurately controls manufacture
Coordinate measuring uses sensors (probe or optical) to check component dimensions
Visual inspection still used (but human error and too late to correct errors)
Intelligent cameras flag up issues - can check every part

Most Quality control and production control – uses computer technology to inspect at every stage of manufacture of a product. Most require sophisticated software – good example is computer controlled probes that measure the exact dimensions of a product. Sometimes optical scanners are used which has the advantage of never touching the actual product. Delicate or large objects can be easily checked and response time is only limited by the system.
Visual inspection is still often carried out. There can be an element of human error with this process and usually involves a random selection of a product from random samples.. This system is usually too late to correct errors that are found and often the whole batch may have to scrapped. Optical testing with a feedback system may shut down production lines at the first sign of a fault.
Intelligent cameras can be programmed to view selected elements of the component and flag up any issues electronically. The camera can check all objects passing in front of it
