Table of contents

Start Divide on groups Brainstorming – select product Make a sketch of your product and draw Bill of material

BOM - Major Input to MRP Process:1. Bill of Material Product structure file Determines which component items need to be scheduled Product Structure Record Clipboard Level 0 Level 1 Level 2 Spring (1) Bottom Clip (1) Top Clip (1) Pivot (1) Rivets (2) Clip Assembly (1) Pressboard (1)

Structure of a BOM The diagram illustrates a bill of material for product A. Product A is made of assembly B, components C and D, and material E. Assembly B is made from components F, G, and H (as well as other assemblies or products). Purchased parts are normally  identified as materials  (items E, F, and G) but can be any product, assembly or component that depending on workload you choose to buy-out or manufacture.

Parts List For components that you buy define suppliers- real companies

Manufacturing process decisions How do we choose the specific manufacturing processes? How do the selected materials influence the choice of manufacturing processes? Would product function or performance issues influence our choice of processes? What criteria should we use to select processes? Which criteria are more important? Who will make the final decisions?

Frame Materials Steel – Strong, stiff, heavy, but cheap Aluminium – weaker, lighter, more expensive than steel Composite (CFRP) – strong, stiff, very light, but expensive to buy and to fabricate
