19、uring process that produces a component,assembly, or product.4. Significance and Use4.1 This guide provides manufacturers a systematic ap-proach for characterizing the environmental aspects of manu-facturing processes utilizing formal representations.NOTE 1A UMP is formally represented using languag

20、es such aseXtensible Markup Language (XML), Unified Modeling Language(UML), or Systems Modeling Language (SysML) to facilitate dataexchange, computability, sharing, and communication with other manu-facturing and analysis applications. These capabilities support manufac-turers in evaluating, documen

21、ting, and improving performance.4.2 This guide provides the required structure and formal-ism to ensure consistency in characterizing manufacturingprocesses in a computer-interpretable way enabling effectivecommunication, computational analytics, and exchange ofperformance information.NOTE 2This gui

22、de will promote new tool development that can linkmanufacturing information and analytics for calculating the desiredenvironmental performance measures.4.3 The guide supports the development of tools to improvedecision support capabilities while facilitating the developmentand extension of standardi

23、zed data and information bases suchas Life Cycle Inventory (LCI) (ISO 14040 series).NOTE 3Data collected within manufacturing enterprises can be usedto build enterprise-or-sector-specific databases that complement or extendLCI databases (ULE 880). This approach will improve the relevancy andcomplete

24、ness of the data while retaining key links to Life CycleAssessment (LCA) methods.5. Unit Manufacturing Process Representation5.1 The UMP representation utilizes graphical and formalmethods in constructing UMP information models for charac-terizing the environmental aspects of manufacturing processes

25、.Formal methods for acquiring and exchanging information willlead to better consistency in these characterizations and helpestablish a consolidated database of environmental measure-ments. Consistency of the characterizations will ensure effec-tive communication of computational analytics and sharin

26、g ofsustainability data.5.2 The graphical representation (Fig. 1) is comprised offour elements (inputs, outputs, product and processinformation, and resources) to systematically identify, collect,structure, and visualize manufacturing information. Structuredinformation of manufacturing processes fac

27、ilitates dataexchange, sharing, and communication with other manufactur-ing applications such as modeling, simulation, and analysistools. It can provide process specific information to LCIdatabases that will support a more detailed and accurate LCA.5.3 To achieve formal representations of manufactur

28、ingprocesses, UMPs require the adoption of a formal modelingmethod or language to effectively convey the meaning andintent of processes they characterize. The complete XSDschema XML Schema Definition Language intended for anXML XML 1.0 implementation of UMPs is presented inAppendix X1.5.4 The basic

29、building blocks of XML Schemas consists ofelements and attributes. Elements can also contain otherelements, that is, child elements. A data type defines the validcontent that child elements and attributes contain.5.5 Table 1 presents the basic elements used in creating aUMP. Fig. 1 presents the rela

30、tionships between these basicelements. Besides the attributes, name, description, and type ofthe UMP, the remaining part of the graphical representation(Fig. 1) is captured in the schema as child elements andincludes input (see 5.5.1), output (5.5.2), feedback (5.5.3),product and process information

31、 (5.5.4), resource information(5.5.5), and transformation (5.5.6 and 6.5). The UMP Namemust be unique among the UMP child elements.5.5.1 InputIncludes all inputs that enter the UMP such asmaterial (for example, raw materials or work-in-progress),consumables (for example, lubrication or forced air),

32、energyand external factors (such as temperature, humidity,particulates, vibration, and shocks) that occur during themanufacture of a product. In the schema, Inputs are describedwith attributes name, type, description, category, and unit.Type defines the material or energy used as input; it can also

33、be“feedback” which implies that a feedback can be connected.Description is a free text explanation. Category classifies theinput and can be Energy, Material, Consumables, or otherexternal factors. Unit quantifies the input to enableconversions, for example, energy, material, or water use.5.5.2 Outpu

34、tIncludes all outputs that exit the UMP modelsuch as products, by-products, waste, and emissions. Output ofone UMP model can be an input to another UMP model. In theschema, Outputs are described with attributes name, type,category, and unit. Type defines the output such as material or5http:/www.w3.o

35、rg/TR/xml.6http:/www.w3.org/XML/Schema.E3012 162energy. Category classifies the output and can be Product,By-product, Waste, or Emission. Unit quantifies the output toenable conversions, for example, energy, material, or wateruse.5.5.3 FeedbackA feedback is a specific Output of thecurrent process st

36、atus. Feedback can be used as input back tothe current UMP, to another UMP, or to other sets of UMPsmodels. The element is defined using a name and a unit. Unitquantifies the value to enable conversions, for example, energy,material, or water use.5.5.4 Product and Process InformationIncludes relevan

37、tinformation to enable the transformation (5.5.6) calculations ofmaterial, energy, and information. This includes items such aspart geometry, material properties, control programs, andprocess plans. The schema ProductProcessInformation de-scribes attributes name, category, description, value, and un

38、it.Category classifies the Product and Process Information and isuser defined. Value defines a number. Unit quantifies the valueunit to enable conversions.5.5.5 Manufacturing ResourceIncludes process resourcessuch as equipment, fixtures, tooling, and inspection gauges.The schema element ResourceInfo

However,the schema can be extended with other types oftransformations, for example, code for simulation or complexfunctions (6.5).An Equation element calculates inputs, outputs,and feedbacks, using l

44、inear equations, with operators such as *,/, +, -, , ( ). The attribute set for equations defines a collectionof equations. The Category of equation calculates material,energy, or information transformations6. Process Characterization Methodology6.1 The UMP graphical representation is illustrated in

45、 Fig.1. This is the first step in the Process CharacterizationMethodology. Section 7 defines composability, the essentialcapability required for creating a network of linked UMPmodels through which specific production plans for a part,assembly, or a product (Fig. 2) can be defined.6.2 The Process Ch

46、aracterization Methodology supportsmanufacturers in deriving specific UMP models for character-izing the environmental aspects of manufacturing processes.The Process Characterization Methodology is comprised of thesteps described in 6.3 through 6.5.6.3 Identify UMPs and KPIs:6.3.1 Select appropriate

47、 UMP/s to be characterized (forexample, Fig. 2).6.3.2 Specify the boundary (Guide E2986) that encom-passes one or multiple UMPs to enable the identification andselection of UMP specific elements (5.5).6.3.3 Product and process information can be common to anumber of UMPs such as material feed-rate o

48、r unique to certainUMPs such as injection molding material injection tempera-ture. Further, additional injection molding information such aspart geometry, engineering specifications, number of moldcavities, and material selection provide important informationon selecting the appropriate equipment, t

49、ooling, and fixtures.6.3.4 Select the appropriate KPIs ensuring process controland product conformance.6.4 Identify UMP Specific Elements:6.4.1 Using the graphical and formal representation, one canidentify and capture the essential information required todevelop the specific UMP models (Fig. 3, for example). Thisincludes the specific inputs, manufacturing resources, productand process information, and outputs for chosen UMP/s.(a) Identify the InputsThe inputs that enter the UMP caninclude intermediate products, work-in-progress (WIP), rawmat
