Q

What are the advantages and disadvantages of batch production

A

Cost saving to buying materials in larger quantities, some flexibility in production, reduces risk of large investments for equipment, faster than one-off

Products can’t be fully customized, finish quality and complexity is limited, relatively slow, quality of finish and complexity is usually less than mass production

Q

What are the advantages and disadvantages of mass production

A

Very high cost saving due to limited wastage and scale of purchases, very fast production cycle, low labor skill required, high production quality, mass production techniques enables more complex shapes

Very expensive investment in machinery, highly skilled labor required to make molds, little/ no flexibility, unable to customize product, not appropriate for certain materials (e.g. woods), machinery dedicated to product

16
Q

What is ISO

A

International Standards Organisation
Not a regulatory or enforcing body
Companies have to apply, are assessed and are then certified
Globally respected

17
Q

What are the advantages of having ISO 9001

A

Promotes quality and safety in procedures/products
Promote product/system compatibility
Encourage/facilitate international trade
Enhances reputation of organisation
Allows for trade with other ISO 9001 certified organisations

18
Q

What 2 marks can be put on products if they meet standards of the testing institutions

A

Kitemark- British standards

CE- European standards

19
Q

What does TQM stand for

A

Total
Quality
Management

20
Q

What is TQM

A

A system of management based on the principle that every member of staff must be committed to maintaining high standards of work in every aspect of a company’s operations

21
Q

What does AGV stand for

A

Automated
Guided
Vehicles

22
Q

What does ASRS stand for

A 
Automated
Storage
and
Retrieval
System
23
Q

What are the advantages and disadvantages of AGV’s

A

Reduced labor costs, increased safety, increased accuracy and productivity, modularity

Potentially high initial investment, maintenance costs, not suitable for non-repetitive tasks, decreased flexibility

24
Q

What are the advantages and disadvantages of ASRS’s

A

Accuracy, efficiency, productivity, volume utilization

Requires customization, expensive to install

25
Q

What does JIT stand for

A

Just
In
Time

26
Q

What is a JIT system

A

The just-in-time (JIT) inventory system is a management strategy that aligns raw-material orders from suppliers directly with production schedules. The JIT inventory system contrasts with just-in-case strategies, wherein producers hold sufficient inventories to have enough product to absorb maximum market demand

27
Q

How do are companies like Land Rover use JIT

A

Factory only holds 4 hours of manufacturing stock at once
Lorries park up next to each part of the factory so it can be unloaded straight onto the production line
Suppliers only have 30 minutes to unload before the next lorry arrives
The supplier isn’t paid till the lorry is on site to make sure it arrives at the right time

28
Q

What is Flexible Manufacture Systems

A

Manufacturing systems that have been set up that allow a company some degree of flexibility to enable it to react to, and then investigate, changes fairly rapidly to the manufacturing process

29
Q

What is machine flexibility

A

Systems ability to change to produce new product types

Ability to change order of operations

30
Q

What is routing flexibility

A

Ability to use multiple machines

Ability to absorb changes such as capacity and capability

31
Q

What does TIMWOOD stand for

A 
Transportation (of materials)
Inventory
Motion (of works/equipment)
Waiting
Over-processing
Over-production
Defects
32
Q

What is Kanban

A

Kanban is a visual system for managing work as it moves through a process. Kanban visualizes both the process (the workflow) and the actual work passing through that process. The goal of Kanban is to identify potential bottlenecks in your process and fix them so work can flow through it cost-effectively at an optimal speed or throughput

33
Q

What is the kanban method

A
  1. Visualize workflow
  2. Limit work-in-progress
  3. Manage flow
    (By seeing what you have to do and have already done, efficiency within workers is increased)
34
Q

What is lean manufacturing and what are the advantages

A

Lean manufacturing is a methodology that focuses on minimizing waste within manufacturing systems while simultaneously maximizing productivity. The benefits of lean include reduced lead times, reduced operating costs and improved product quality

35
Q

What are the advantages of quick response manufacturing

A

Reduced time to market (lead time) which in turn has the following benefits: The ability to keep up with trends/fashion/demand/orders, Increased Market Share (ability to capitalize on early interest and orders that require a short turn around), Recoup money quickly and improve cash flow
Allows customization/flexibility/adaptability
Reduced retooling costs (due to FMS)
Labor costs reduced (due to automated nature of FMS)
Reduced human error/waste ((due to automated nature of FMS)
Storage costs reduced (due to JIT)
Ultimately it should therefore encourage repeat business (due to improved customer satisfaction, confidence and improved reputation)

36
Q

What is quick response manufacturing

A

Quick response manufacturing is a concept whereby business set up their design and manufacture to allow them to respond to changes in their market and customer requirements with minimal delay

37
Q

What is Enterprise Resource Planning

A

Enterprise Resource Planning is a system that helps companies integrate and manage all their financial, supply chain, manufacturing, operations, reporting, and human resources activities.

38
Q

What is Product Data Management

A

Product Data Management is the use of software to manage product data and process-related information in a single, central system. This information includes computer-aided design (CAD) data, models, parts information, manufacturing instructions, requirements, notes and documents. The ideal PDM system is accessible by multiple applications and multiple teams across an organization.

39
Q

What is over the wall designing

A

During the industrial revolution, technology became more complex. The complexity forced forced employees of companies to specialize in different areas of the product design process. No longer could one person be responsible for the design, manufacture and sales of a product. The era of the craftsmen gave way to the era of the specialist. Large companies began to organize their into departments with different responsibilities. Each department worked on a product until they had completed their tasks and then they handed off the project to the next department. Not only was this serial process very slow but it also caused many problems when the communication between departments broke down. The breakdown of communications led to projects being thrown back over the walls that divided the departments for rework.
