Suggestion of "PDM at PLM" model: "conveyor at assembly line"

The understanding of collaborative design process could be represented using assembly line model. In this model PDM as it is, could be represented as conveyer belt. PDM tools - as automated robots. CAD software - as instruments at worker’s hands. Workstation computer - as workbench.

The conveyor belt is moving from past into the future, and from the start of the project, through the desing process straight to the project closing. It carries “details” (documents, models, drawings), and allows to employees (end users, engineers, project managers, Quality Department) join the process in right time.
Workers are building models, using boxes of parts (components libraries, standard solutions library), that they really need at current stage of project. This conveyor could be branched, for parallel work.

The abstraction of check in (check out) operations with this model becames more comprehensible -- it’s operation of taking (returning) working part by employee from (back to the) belt into (out from) workplace to provide certain operations.

Why is assembly line model useful?

The common submission of PDM solutions and PDM systems of end-users, customers and some of implementors grotesquely represented hereinafter. There is PDM, to which everybody are connected. There is necessity of employees to do their work. But how, why, what for -- there is no common answer and often even there’s no this questions.

Common submission of PDM and PDM
The conveyor model solves this problem: everybody can see what’s he doing as a part of work process within the project and company. It’s easier for integrators to build actual PDM model , using customer’s business process models.

Using of model brings next benefits: becomes possible to use common math and business methods of assembly line theory: atomize big jobs at smaller parts, using less educated personal, etc. At now PDM could be developed as assembly of pre-configured parts, and you can clearly see, which “robots” are you need to include into line to automate handworks. Also it allows to build more flexible solutions and even automatically calculate their models, according to requirements.

I'd like to hear your opinion.
