 DDMRP
 =====
 
-Pending...
+Demand Driven Material Requirements Planning is a formal multi-echelon
+planning and execution method developed by Ms. Carol Ptak and Mr. Chad Smith.
 
+DDMRP combines blended aspects of Material Requirements Planning (MRP),
+Distribution Requirements Planning (DRP) with the pull and visibility
+emphases found in Lean and the Theory of Constraints and the variability
+reduction emphasis of Six Sigma.
+
+This method has five sequential components:
+
+#. *Strategic Inventory Positioning*. Answers the question "Given our system
+   and environment, where should we place inventory to have the best
+   protection?" and determines where should decoupling points of inventory be
+   placed.
+
+#. *Buffer Profiles and Levels*. Determine the amount of protection at those
+   decoupling points.
+
+#. *Dynamic Adjustments*. Allow the company to adapt buffers to group and
+   individual part trait changes over time through the use of several types
+   of adjustments.
+
+#. *Demand Driven Planning*. Allow to lauch purchase orders (POs),
+   manufacturing ordrers (MOs) and Transfer Orders (TOs) based on the priority
+   dictated by the buffers.
+
+#. *Visible and Collaborative Execution*. These POs, MOs and TOs have to be
+   effectively managed to synchronize with the changes that often occur within
+   the "execution horizon."
+
+These five components work together to greatly dampen, if not eliminate,
+the nervousness of traditional MRP systems and the bullwhip effect in
+complex and challenging environments.
+
+This approach provides real information about those parts that are
+truly at risk of negatively impacting the planned availability of inventory.
+
+DDMRP sorts the significant few items that require attention from
+the many parts that are being managed. Under the DDMRP approach,
+fewer planners can make better decisions more quickly. That means companies
+will be better able to leverage their working and human capital.
+
+Demand Driven Material Requirements Planning is quickly being adopted
+by a wide variety of leading companies across the world.
+
+Some of the benefits reported by the DDMRP method include:
+
+* High fill rate performance
+* Lead time reductions.
+* Inventory reductions, while improving customer service
+* Eliminate costs related to expedite
+* Planners see priorities instead of constantly fighting the conflicting
+  messages of MRP
+
+It is highly recommended to read the book 'Demand Driven Material
+Requirements Planning (DDMRP)' by Carol Ptak and Chad Smith.
+
+Installation
+============
+
+To install this module you need to first download modules from other OCA
+repositories:
+
+Modules from http://github.com/OCA/web :
+
+* 'web_tree_dynamic_colored_field'
+* 'web_widget_bokeh_chart'
+* 'web_tree_many2one_clickable'
+
+Modules from http://github.com/OCA/stock-logistics-warehouse :
+
+* 'stock_warehouse_orderpoint_stock_info'
+* 'stock_warehouse_orderpoint_stock_info_unreserved'
+* 'stock_available_unreserved'
+* 'stock_orderpoint_uom'
+* 'stock_orderpoint_manual_procurement'
+* 'stock_demand_estimate'
+
+Modules from http://github.com/OCA/server-tools
+
+* 'base_cron_exclusion'
+
+We strongly recommend to **uninstall** ``procurement_jit`` (so deliveries
+related to Sales Orders aren't automatically reserved) and to avoid to
+reserve stock for specific moves, buffers are in fact a reservation of stock.
+However, while **reservation is discouraged**, it is still available to be
+used, in case of reserved stock be aware that the buffer will be blind to this
+transfers and stock and you are bypassing the DDMRP reordering flow.
+
+Configuration
+=============
+
+Scheduled actions
+-----------------
+
+* Go to *Settings > Technical*.
+* 'DDMRP Buffer ADU calculation'. Computes the Average Daily Usage for all
+  Buffers.
+* 'Reordering Rule DDMRP calculation'. Computes the Qualified Demand, Net
+   Flow Position, Planning and Execution priorities for all Buffers.
+
+Decoupled Lead Time computation
+-------------------------------
+
+The DLT is automatically computed by the system.
+
+A) For manufactured products' buffers just remember to provide and
+   set properly the following information:
+
+* The *Manufacturing Lead Time* for the manufactured product. It can be found
+  at the product form view under the tab *Sales*.
+* The *Delivery Lead Time* for the preferred vendor of a product. This is
+  important for the products which are purchased and are components in any
+  Bill of Materials.
+
+B) For purchased/distributed products' buffers the logic is simpler.
+
+* In the first place the system will look if there are Vendors for the product,
+  if so it will use the *Delivery Lead Time* of the preferred one.
+* In case of absence of vendors, the *Lead Time* at the bottom of the Buffer
+  form view will be used.
+
+Usage
+=====
+
+To easily identify were are you maintaining buffers in your Bill of
+Materials, you will need to first provide location information on the Bills
+of Materials.
+
+* Go to *Manufacturing / Products / Bill of Materials* and update the
+  'Location' in all the Bill of Materials and associated lines,
+  indicating where will the parts be placed/used during the manufacturing
+  process.
+
+* Print the report 'BOM Structure' to display where in your BOM are you
+  maintaining buffers, and to identify the Lead Time (LT) of each product, and
+  Decouple Lead Time (DLT).
+
+
+Buffers
+-------
+
+To list the list of inventory buffers, go to one of the following:
+* *Inventory / Inventory Control / Stock Buffer Planning*
+* *Inventory / Inventory Control / Reordering Rules*
+
+
+Buffer Profiles
+---------------
+Buffer profiles make maintenance of buffers easier by grouping them in
+profiles. Changes applied to the profiles will be applicable in the
+associated buffer calculations.
+
+* Go to *Inventory / Configuration / Buffer Profiles*.
+
+The Buffer Profile Lead Time Factor influences the size of the Buffer Green
+zone. Items with longer lead times will usually have smaller green zones, which
+will translate in more frequent supply order generation.
+
+* Go to *Inventory / Configuration / Buffer Profile Lead Time Factor* to
+  chan
+
+The Buffer Profile Variability Factor influences the size of the Buffer Red
+Safety zone. Items with longer lead times will usually have smaller green
+zones, which will translate in more frequent supply order generation.
+
+* Go to *Inventory / Configuration / Buffer Profile Lead Time Factor*.
+
+Usual factors should range from 0.2 (long lead time) to 0.7 (short lead time).
+
+
+Product attributes
+------------------
+
+* For manufactured products, go to *Manufacturing / Products* and
+  update the 'Manufacturing Lead Time' field, available in the tab *Sales*.
+* For purchased products, go to go to *Purchasing / Products* and update the
+  *Delivery Lead Time* for each vendor, available in tab *Invenory* section
+  *Vendors*.
+
+
+ADU Calculation Methods
+-----------------------
+
+The Average Daily Usage (ADU) defines the frequency of demand of a product in a
+certain location.
+
+#. Go to *Inventory / Configuration / ADU calculation methods*.
+#. To create new, indicate a name, calculation method (fixed, past-looking,
+   future-looking), and the lengh of period consideration (in days).
+
+If you do not have prior history of stock moves in your system, it is advised
+to usefixed method. If you have past-history of stock moves, best use
+past-looking method.
