The connected applications technology of WBS and BOM in infosystem

Technical field

What the present invention relates to is information systems technology field, is specifically related to the connected applications technology of a kind of WBS and BOM in infosystem.

Background technology

WBS:Work Breakdown Structure work breakdown structure (WBS) is a very important concept in project management.According to the definition of PMI, WBS is the task that the noun: Gong Zuo – be made up of 3 key elements can produce Tangible results; Fen Xie – is a kind of hierarchical structure progressively segmenting and classify; Knot structure – organizes each several part according to certain pattern.

BOM:Bill of Material Bill of Material (BOM) is product structure data, is also the master document of the manufacturing informatization systems such as PLM/ERP/MES.BOM is the in detail all lower rank material of record used by a product and association attributes, that is, the subordinate relation of father's part and all components, unit dose and other attribute.BOM is also referred to as detail list, material list or formulation material table.

In manufacturing industry, project management and the management of product are all very important actions.Project management visitor is applied in the whole process of order, comprises the Task-decomposing in the stages such as sale, research and development, production, buying.Current infosystem all follows PMI project management theory, and the WBS carrying out standard decomposes.Below the example of a WBS:

XXX order items

|--1 pre-sales stage

| |--1.1 sales call

| |--1.2 submit a quotation and scheme

| |--1.3 sign a contract

|--2 product designs

| |--2.1 mechanical structured member designs

| | |--2.2.1 Strength co-mputation

| | |--2.2.2 CAD drawing protract

| |--2.2 electricity piece designs

| |--2.3 technological designs

|--3 fabrication phases

| |--3.1 outsourcing materials

| |--3.2 self-controls are produced

|--4 the delivery stages

|--4.1 quality inspection warehouse-ins

|--4.2 ship delivery

Table one: the WBS example of a representative items

Product BOM is from product data angle, to a division of spare part material, generally uses (being likely the various ways such as EBOM/PBOM/MBOM) in research and development, technique, manufacture and acquisition phase.Current infosystem is all the data structure according to parent-sub-level, is stored in by BOM in database or file.Below the example of a BOM:

XXX product/P001

|--shell assembling/A001(quantity: 1 PCS)

| |--fore shell/P01(quantity: 1 PCS)

| |--back cover/P02(quantity: 1 PCS)

| |--rivet/S01(quantity: 4 PCS)

|--connecting rod/P03 (quantity: 1PCS)

|--motor assembling/A002(quantity: 1 PCS)

| |--motor/A003(quantity: 1 PCS)

| |--set bolt/GB1000 (quantity: 4 PCS)

|--4 accessories/A004

|--4.1 spanners/AT01(quantity: 1 PCS)

|--4.2 base plates/AT02(quantity: 1 PCS)

Table two: the BOM example of a typical products

In the Task-decomposing of enterprise practical, often need to divide task according to BOM structure, such as, shell assembling/A001 is responsible for carrying out design objective, technologist B to carry out process task, workshop C to carry out production and processing task by designer A; And the component P01/P02/S01 of shell assembling/A001 by product structure similar carry out task resolution; Wherein, the design objective carried out for designer A, has and needs according to WBS to be decomposed into structural design, electrical design two subtasks, and structural design is decomposed again and is divided into Strength co-mputation and CAD drafting.
