Methodology used
• For MDT 219 mast cabs and fixed towerhead
part 1.6M, the following MRP parameters were
analyzed and adjusted:
1. Goods receipt time;
2. Safety margin;
3. Safety stock (equivalent in days of
stock).
• The methodology used was measuring
manufacturing times for the structures,
extracting data on SAP programmed
manufacturing times (routing times + 1,2 and
3), analyzing whether there are discrepancies
between both durations and highlighting the
margin which is possible to adjust.
• By reducing the SAP programmed
manufacturing times and material management
times, it was possible to reduce the inbound
level of stock for raw materials allocated
identified Manufacturing Bill of Materials -
MBOMs of structures since backward scheduling
order dates are set closer to current date.
Improvements
• Reduced level of stock for raw materials
(mainly cab mast ferrules and plates as
well as fixed towerhead part ferrules and
sheet metal – bottom and top);
• Warehouse space occupation improved
(mainly for cab mast’s plates and
towerhead part sheet metal – bottom and
top);
Estimated gains
33,5% reduction to monthly stock for
materials;
12,4% reduction to monthly overall raw
material’s warehouse (Canopy) stock;
110 000 euros monetary monthly gains
(estimated at the time of
implementation).

Impact processes in the long run
Methodology used
• The task force created extracts data on materials
supplied by Wurth for every crane model and
equipped structure (including yard box), does
groundwork evaluating discrepancies in what
is programmed in SAP and what is used by
assembly, making adjustments;
• Materials are divided by assembly phase and
organized in boxes (as shown in the picture);
• Scope included optimizing warehouse storing
of said materials to ensure those kits are
assembled as swiftly as possible.
Improvements
• Removes assembly workers
movements to pick material;
• Reducing inventory discrepancies,
assures that materials supplied to assembly
are those programmed in SAP in the right
quantity;
• Improves assembly productivity;
• Eliminates engineering errors
programmed in SAP.
Each compartment
contains the materials
needed in one
assembly phase
Finalized kit is then coupled
into the picking kart for
specific production cell
Future work
• Developing an easy way to generate all
the kit picking lists needed for each crane
sales order and distributing them for
warehouse workers.

EFFECTS
Impact processes in the long run
Methodology used
• In order to improve information flow between
production and warehouses regarding material
shortages, alerts are emitted by production
workers, through Easy Prod;
• The alert is received by warehouse supervisors
team leaders and select Supply Chain members
(by e-mail and SMS), triggering a response
that may involve supplying the material if it is
available or informing MRP controllers when not
available;
• The alerts are also constantly visible on a
screen displayed centrally in the warehouse,
making it possible by everyone in the warehouse
to have the same information.
Improvements
• Optimized information flow between
production and warehouses;
• Clearer information about material
shortages;
• Faster reaction time by MRP controllers;
• Allows data warehousing for future
analysis and patten acknowledgement;
• Improves inter-shift information flow.
Future work
• Using the same methodology for exterior
warehouse (it is currently implemented
exclusively in raw materials warehouse –
Canopy and Commercial Warehouse).

Notation 2.0 is introduced;
• As processes are modeled with this notation it’s
possible to simulate processes in the future
with proper data gathering.
• It’s then possible to identify bottlenecks,
resource pressure and margin gains by
increasing and reducing resources.
Improvements
• Clearer and holistic notation for

Methodology used
• For every material in every warehouse (Canopy,
Commercial and Exterior Warehouse), the
previous years entries and exits are
analyzed;
• Materials with no exits are highlighted and for
those materials, following years needs are
also analyzed;
• Materials with no entries in the previous year
and no needs for the following year are
segregated and quarantined for three
months;
• After the quarantine period if there are no further
changes the materials have one of three
solutions: intercompany sale, a 3rd party sale
or scrapping.
Improvements
• Freeing warehouse space occupied
by materials that do not have
forecasted needs;
• Identification of possible SAP
MBOMs errors (materials that are
generating needs but are not used
physically by production workers);
• Removes wasteful materials from

of reorganizing them.

Methodology used
• First, a label layout was developed to
include all the information needed my
warehouse and production workers when
identifying a material;
• Then it is analyzed whether a certain
rack’s layout needs readjustments or
materials may be organized in a different
way (by crane model, crane structure or
other criteria;
• Finally, and when racks are organized in the
optimal way, previous labels are replaced
by current ones.
Improvements
• Improvement to the information
available for warehouse and
production workers through labels;
• Ease of locating materials by
defining localizations for materials;
• First step in picking material
segregation for production orders at
raw materials warehouse (Canopy);
• Reducing the occurrence of

Impact daily/weekly processes
Methodology used
• This project allows supplying warehouse
workers with more complete
information about MBOMs than the
ones extracted directly from SAP (MRP
controllers for each material and 3D
drawings);
• Furthermore, it is a way to make sure
distributed MBOM’s aren’t
outdated/incorrect since data is
extracted to Excel directly from SAP and
there is information in the document
about when it was printed and its
expiration date.
• Every time a MBOM is printed, a registry is
made on the date it was printed and who it
was given to.
Improvements
• Providing warehouse workers with
more complete information;
• Allows warehouse workers to checklist
the materials needed for a certain
structure and pinpoint eventual
material shortages, informing the
respective MRP controller immediately;
• Removes incorrect or outdated
MBOM’s from circulation.
