Problem Statement

• Manufacturing systems, process and data are
  becoming more complex
• Need to exchanging and sharing data between
  manufacturing applications and simulations
• Factors prohibits use of simulation technology
• Economic
• Cost of implementing and using simulation
  technology is high
• Technical
• Lack of interoperability
• Need to develop reusable, neutral standard
  interfaces

Benefits of simulation technology and interface
standards

• The Integrated Manufacturing Technology Roadmap
  (IMTR) stated that "Modeling and simulation (MS)
  are emerging as key technologies to support
  manufacturing in the 21st century, and no other
  technology offers more than a fraction of the
  potential that MS does for improving products,
  perfecting processes, and reducing
  design-to-manufacturing cycle time."
• The National Research Council (NRC 1995) has
  repeatedly identified simulation and modeling as
  a high priority research area.
• Another NRC report (1999), titled "Defense
  Manufacturing in 2010 and Beyond Meeting the
  Changing Needs of National Defense"
• NIST study 1999 the inability to freely exchange
  manufacturing data within the supply chain is
  costing the US auto industry 1B per year
  (www.mel.nist.gov/div826/msid/sima/sima.htm and
  www.nist.gov/director/prog-ofc/report99-1.pdf).

Goals

• Enable data exchange between simulation systems,
  other software applications, and databases,
• Support the construction of manufacturing
  simulators,
• Support testing and evaluation manufacturing
  software, and
• Support manufacturing software application
  interoperability

Technical Approach ?

• Develop data structures for exchanging
  manufacturing data
• Use the same data structures for managing
  production operations and for simulation the
  manufacturing shop floor.
• Minimize the need for translation and abstraction
• Maintain data integrity
• Minimize duplication of data

8
Technical Approach ?

• The program will
• identify critical manufacturing process and
  system simulation domains and associated types of
  simulation software applications
• analyze current and future trends for simulation
  and testing technology
• establish specification and testing methods,
  models, and metrics for validating simulation
  systems interfaces
• identify tools and models to be used in the
  specification development, prototyping, and
  testing processes
• construct a test bed containing simulation
  applications, prototype integration, testing
  tools, and test cases
• specify and develop architectures, data models,
  and interface specifications for integrating
  simulation applications, component modules, and
  reference libraries
• conduct experimental tests, industry
  demonstrations, and reviews to substantiate the
  validation and testing process itself and
• promote specifications as candidate standards
  within the national and international standards
  community.

Scope

• The CMSD Information Model describes the entities
  in the manufacturing domain and the relationship
  between these entities that are necessary to
  create manufacturing simulation.
• manufacturing domain includes, but not limited
  to
• production control,
• process planning,
• scheduling,
• inventory management,
• production management, or
• supply chain management, etc.
• There is no specification of execution behavior
  of manufacturing syste
• No support provided for the creation of
  programming language or simulation language
  execution constructs, or the association of such
  constructs with the manufacturing entities
  defined in the CMSD information model.

Major data categories

• Organization is used to maintain organizational
  structure, contacts and address information for
  the manufacturing organization and its customers
  and suppliers.
• Calendar identifies the shift schedules that
  are in effect for a period of time, breaks and
  holidays.
• Resource describes all the resources that may
  be assigned to tasks in the shop. The resource
  types available in the shop environment include
  stations and machines, cranes, employees, tool
  and fixture catalog items, and user-defined type
  of resource.
• Skill definition lists the skills that an
  employee may posses and the levels of proficiency
  associated with those skills.
• Setup definition typically specifies tool or
  fixture setups on a machine. Tool setups are
  typically the tools that are required in the tool
  magazine. Fixture setups are work holding devices
  mounted on the machine. Setups may also apply to
  cranes or stations.

Major data categories (cont)

• Operation definition defines the operations
  that may be performed at a particular station or
  group of stations in the shop.
• Maintenance definition defines preventive or
  corrective maintenance to be done on machines or
  other maintained resources.
• Part provides elements for part specifications,
  group technology codes, customers, suppliers, as
  well as links to bill of materials, process
  plans, drawings, part models and other
  references.
• Bill-of-materials cross-references the parts
  and quantities required in a hierarchical bill-of
  materials structure.
• Inventory identifies the instances and
  locations for part, materials, tool and fixture
  inventory.
• Process plan specifies a set of process plans
  that are associated with production and support
  activities for a particular part or parts. A
  process plan has routing sheets and operation
  sheets that correspond to the job and task level
  in the work hierarchy.

13
Major data categories (cont)

• Work is used to specify a collection of a
  hierarchy of production orders, jobs and tasks.
  It is also used to specify a collection of
  internal support orders for maintenance
  activities, inventory picking and tool
  preparation.
• Schedule lists planned assignment or mapping of
  work to resources and resources to work.
• Revision specifies information about a set of
  revisions of the subjects. Information included
  in the element are each revisions description,
  date, creators, etc.
• Probability distribution specifies
  distributions that are used to vary processing
  times, breakdown and repair time, and
  availability of resources, etc.
• Reference describes the information about
  reference materials that support or further
  define that data elements contained within the
  CMSDIM data structure.
