MovsisyanNaturalStoneProcessingCompany Visit Summary 19 September, 2005
Value Added • Giving high-quality shape to natural stones mostly for construction. • High quality means: certain types of symmetry; high flatness; mass production; also artistic design.
Reasons for Success • Using abundant Armenian stone resources, namely basalt, tufa, travertine, felsites. • Is not only processing, but minig operation - owning two quarries. • Using the most modern Copmuter Numerical Controlled (CNC) machine tools. • Entering the world market by special production, NOT granite and marble!
Why Italian Machines? • Italy has ages of experience of using stones for construction, for interior decoration. • Produced and exported both stones and machine tools. • Has a very developed infrastructure in this area, including many quarries, plants, schools, etc.
Plant Specificity • Order based production. • Diversity of orders:- cutting clods;- cutting façade tiles;- specific ornamental elements;- columnsVery important to note that all these types specify different operational logics.
Cutting ability • Cutting wafers – parallelepipeds – clods and tiles. • Cutting by cylindrical symmetry. • Cutting by rotational symmetry. • Drilling holes. • Any 3D shape – manually.
Plant Specificity • Inventory is everywhere: need to investigate the reasons from the operational point of view! • Total WIP is very large. • Setup times:- transporting the clods;- setting up machine tools – program should be ready, the cutting tools should be new!- tests, quality control.
Waste • It is possible to collect all the waste and possibly use it for:- as other construction elements;- as fill for various paints, putty, etc.;- for chemical production. • Waste comes from:- cutting process;- nonconformity of sizes – leftover.
Waste • Total waste amount of an order may reach more than 90%! Though usually it is 40% - 60%. • As one of you mention, it is important to find out if the waste is stored mixed or sorted. • It is clear that it is not very expensive to store the wastes separately.
Waste of Time • Waste of Time is the most important waste, since the plant operates close to its maximum cacity: in Summer they work 3 shifts! • If you have orders, each percentage of time waste corresponds to the same percent of of lost sales and profit!
Balance Is this production balanced?
Facilities Layout • One big U-shaped workshop! • However, the diversity of the processes may dictate a different layout. • In general the layout issue is connected with the question of the inventories: need to investigate the reasons of large inventories from the operational point of view!
Working Conditions • Dust • Moisture • Noise • Lighting • Safety
Development directions • 50% percent of workers were laid off. Why? • Possibly due to the new clod-cutting machine. • Armenia is a country of stone. Plus… • A lot of construction goes on:
Development directions • Cooperation with construction companies. • Research in Industrial Engineering • Research in Materials science for:- non-destructive defect monitoring;- new directions of construction science development where stones are used;- … (search will show).
How to start writing a report? • Look at the available information:- Company web site;- Your notes;- Photos. • Write your main points in the form of bullets – a plan of report. • Than add your comments, remarks, suggestions, calculations or any other observations. • Only after this go to Internet, brochures, etc. to illustrate and enrich your ideas.
