Materials Requirements Planning
Franz Birsel

Task of Disposition

• Due providing of the necessary material
  requirement
• Providing of the material requirement for the
  disposition
• Providing of the internal material requirements
• Long-term management of the material availability
• Dissolving lists of material
• Preparation of planned orders for the production
• Preparation of Beschaffungsvorschlägen for the
  purchasing dept.

3
Methods of Dispositions

• Consumption-driven Dispositionbased only on the
  use of materials in the past
• Deterministic or demand-driven Dispositionbased
  on the demand of materials in the future

4
Consumption-driven Disposition

• Activator of production- or providing demands in
  the consumption-driven disposition is the
  undercutting of a defined minimum stock level
• The stock level should be high enough that the
  provision of material during the delivery time of
  the supplier or the time of inplant production is
  secured

5
Deterministic Disposition

• Activator of the production- or providing demands
  in the deterministic disposition is the existence
  of pegged requirements These are e.g.
• Customer orders
• manually triggered production orders Planaufträge
• The deterministic disposition does not produce
  any supply which are not really needed

6
Types of Disposition

• Single item, single-level planning
• Single item, multi-level planning
• Total planning

7
Single itemSingle-level planning

• Single item, single-level planning is conducted
  manually online
• Only the entered material is planned. If the
  material has a bill of material, the bill of
  material will be dissolved and all materials of
  this bill of material planned.
• Subjacent lists of materials are not planned.
• The single-object single-stage planning is
  usually conducted in the warehouse in order to
  check the availability of each material.

Single itemMulti-level planning

• The single item, multi-level planning is
  conducted manually online.
• The entered material is completely planned. If
  the material has a bill of material, the bill of
  material will be dissolved and all materials of
  this bill of material planned.
• Subjacent bills of materials are planned up to
  the lowest level.
• The single-object single-stage planning is
  usually conducted in the production management
  and control in order to check the availability of
  every material of a production order.

9
Overall Planning

• The overall planning can be conducted manually
  online or as background job.
• As a rule the overall planning is periodically
  automatically planned.
• The period depends on how flexible the production
  has to react to changes in the pegged
  requirements.

10
Amount of the overall planning

• New PlanningA new planning is normally conducted
  only by implementing a system
• All materials are planned that have a valid
  dispo-attribute.
• Net-Change-PlanningEvery disposition-relevant
  change of material places internally an attribute
  on the material level which marks the material
  for the next planning.
• The advantage is a reduction of the duration of
  planning materials which have not been changed,
  will not be handled.

11
Level of Disposition Planning

• The demand planning is generally conducted on
  factory level, i.e.in planning the whole
  available stock in the factory will be
  considered.
• The stocks of several storage locations can be
  dissolved or planned independently from the
  disposition. These stocks will not be counted in
  the disposition on the factory level.
• Moreover, the demand planning can also be
  conducted for several fields of disposition. In
  one field of disposition more storage locations
  can be combined and the demand planning can be
  conducted separately from the factory for this
  field of disposition.
• Fields of disposition enable also a
  differentiation of the demand planning within a
  factory.
