Functional modeling of anod grounding modules manifacturing for electrochemical protection from corrosionAnode grounding modules provide electrochemical protection against corrosion of metal constructions. The functional modeling technique includes sequent decomposition of manufacturing and quality control processes. The functional-technological model describes activities, technological equipment, raw materials, and quality requirements. The complex functional model in IDEF0 notation is presented.

Development and application of the generalized functional model of one-stage chemical manufacturingOne of the approaches of chemical manufacturing information support is model-driven engineering
which focuses on the abstract representation of the knowledge as the domain model. From one
side, domain models are intuitive and user-friendly for the expert. From the other side, such models
are formal and can be translated to software constructions. The IDEF specifications are used for the
model definitions creating. First, we provide the generalized functional model on the basis of informal
descriptions of one-step chemical manufacturing. We begin with top-level context diagram to specify
the main inputs, outputs, controls and mechanisms of the chemical manufacturing. From this diagram
the derived diagram is generated. The derived diagram describes the sequence of base technological
steps such as row materials preparation, chemical transformation, product refinement and condensate
separation. The quality inspection is added to the end of the sequence. Feedback arrows present recycles
of raw materials. Then the implementation of this model for the production of methyl tertiary butyl
ether is described. The detailing of the generalized model means naming of functional blocks and
arrows while the model structure does not change. So the generalized model can be treated as a template
for any chemical one-stage manufacturing model.

DSL-based approach for chemical industry technological schemes design
The justification of technological schemes design automation significance for the chemical industry
application area is provided. The solution by developing of the specific application area oriented tools
is suggested. Proposed combination of custom formal system and domain specific languages approach
provides the means to technological scheme model manipulations. These manipulations includes as
schemes development as their validation according to subject matter expert restrictions and recommendations.
To support it, formal system should include both experimental and industrial production
technological schemes description languages and these languages constructions mutual mapping. The
set of requirements to such formal system and its elements is defined. In addition we demonstrate the
promising of the proposed approach with joint development of the formal system main components.
The resulted formal system gives us the ability to develop as experimental production technological
schemes as derived industrial ones with real practical capacities and constraints accounting.
