Introduction

Creating the “MBOM”

A prerequisite for making a DFX analysis is to have an “MBOM” (Manufacturing Bill of Material) that we want to analyze with some kind of DFX approach (e.g. DFA2 part level). A MBOM in AVIX is represented as a hierarchy of Components.

Short explanation of the concepts part and Item in AVIX.

In AVIX, a “part” represents the definition of a part or product. It has the following attributes: name, product number, length, volume, weight, version and type (Fastener or Value object).

AnA part in AVIX can typically be used, or instantiated, in different BOMs. This is essentially what the concept of “part” in AVIX addresses: A part, which comes in the shape of either a (sub)assembly or detail, describes the usage of a pre-defined part in a specific BOM. This means that a single Item can be used/instantiated in several different BOMs (or in different occurrences within the same BOM structure).

The part thus keeps a reference to its Item, but also adds the quantity attribute, which describes the number of consumed/required Item at that place within the BOM.

During the subsequent sections, the relationship between Components and Items will be described more thoroughly by the use of examples.
