inventory_item

The business objects introduced in the Business Information Overview section are modelled in PLCS through a set of business templates. Most business templates are based upon one or more generic PLCS templates. They may be specializations of a PLCS template using one or more classifications or characterizations to capture the required information, whilst some rename and use restricted parameters.

This section summarizes the mappings of the business objects to the corresponding templates.

Business Object	Business Object Definition	Business Templates
Message	This information object represents a communicated statement of events, activities, or outcomes that have taken place.	UK_Defence.message and UK_Defence.contract
Record	This information object represents the permanent statement for preserving the memory or knowledge of facts, activities or events.	UK_Defence.record
Activity	This information object represents the related activity for which the facility may be demanded.	UK_Defence.activity
Demand Support Activity Relationship	This information object represents the mechanism to reference the related activity for which the facility may be demanded.	UK_Defence.demand_support_activity_relationship
Document	This information object represents reference material that follows a formal change approval mechanism.	UK_Defence.document
Document Association	This information object represents the association of a Document with another information object	UK_Defence.document_association
Facility	This information object describes how to represent an installation providing one or more functional capabilities necessary to provide support to one or more equipment programmes.	UK_Defence.facility
Inventory	This information object represents the inventory authorized to be managed by an organization.	UK_Defence.inventory
Inventory Item	This represents the authorized quantities and locations of items of supply to be managed as part of an organization's inventory.	UK_Defence.inventory_item
Inventory Item Demand	This information object represents a demand/request for an inventory item.	UK_Defence.inventory_item_demand
Inventory Item Return	This information object represents the record of an inventory item being returned from one unit to another, because of it needing repair, being surplus to requirement, being obsolete, or having been delivered to the wrong location.	UK_Defence.inventory_item_return
Item of Supply	This information object represents an item that is managed by the supply chain.	UK_Defence.item_of_supply and UK_Defence.item_of_supply -> UK_Defence.product_design or UK_Defence.item_of_supply -> UK_Defence.product_specification or UK_Defence.item_of_supply <- UK_Defence.related_nato_specification -> UK_Defence.nato_item_of_supply_specification
Location	This information object defines a location.	UK_Defence.location
NATO Item of Supply Specification	This information object represents a specification for a codified item of supply, identified by its Nato Stock Number (NSN). The specification includes the information required to configure and manage the MoD supply chain.	UK_Defence.nato_item_of_supply_specification
Organizational Unit	This information object describes how to represent an organization that is identified by a Unit Identification Number (UIN). Units have a planned or actual base location in which it may be deployed at specific times.	UK_Defence.organizational_unit UK_Defence.organizational_unit_non_standard_location UK_Defence.identifier
Organizational Unit Non-standard Location	This information object represents the relationship between an organizational unit and the planned or actual locations in which it may be deployed at specific times.	UK_Defence.organizational_unit_non_standard_location
Person	This information object represents the information describing a human being. This represents the information describing a human being.	UK_Defence.person
Product	This information object represents the information about a physical instance of a Product Design. Individual products are typically identified by a serial number, and batches are typically identified by a batch number. Both of these would be captured by the referenced Identifier information object.	UK_Defence.product
Product Design	This information object represents the identification of the aggregated set of information that constitutes the detailed design of a product. Product designs can be of any "level" of product, from individual nuts and bolts, up to complete equipments, systems and platforms. Product designs are typically identified by a design authority part number, and when fully specified, will have a detailed drawing/product model associated with them that contain the level of detail that enables instances of the physical elements of the design to be manufactured and/or assembled. Those physical elements will be fully specified by their own Product Design. Product designs will typically also have associated performance specifications, physical characteristcs (such as dimensions, weight and material specifications), and other charateristics such as cost. Prior to this level of detail being defined, the product design process may involve specification of functions, conceptual physical design/general layout design and identification of spatial zones within the design. NOTE: This information object is not meant to contain the detailed design information objects themselves (the goemetry, topology, dimensions, tolerances, material specification, surface finishes etc). It is meant to act as the single reference point to which all that other information relates.	UK_Defence.product_design
Product Specification	This information object represents the specification of a type of product in terms of its functional and/or physical characteristics. A product specification does not contain the level of detail neccessary in order to manufacture and / or assemble a product that meets the specification. That level of detail is only provided by a product design. Typical Product Specifications are those defined by each NATO stock number classification, and those defined by industry standards specifications for items such as nuts, bolts, tyres, etc. Several Product Designs by individual design authorities may meet the requirements of a Product Specification. Such product specifications can be referred to by the elements of a Product Design as well as/instead of an individual Product Design, depending on the item in question. NOTE: The characteristics that define a Product Specification are defined by the Property information object. NOTE: The document(s) that define a Product Specification are defined by the Document Association information object.	UK_Defence.product_specification
Resource Allocation	This information object represents the allocation of a resource to an activity.	UK_Defence.resource_allocation
Resource Demand	This information object describes how to represent a demand for resources. This may be to support a specific activity, or for an anticipated but unspecified need.	UK_Defence.resource_demand
