Significance and Use4.1 This guide provides a reference to the manufacturingcommunity for the evaluation of environmental sustainabilityaspects of manufacturing processes. This guide is intended toi

20、mprove efficiencies and consistencies of informal methods byproviding procedures for consistent evaluations of manufactur-ing processes.4.2 This guide describes a procedure to identify parametersand models for evaluating sustainability metrics for a particularprocess. Users of this guide will benefi

21、t from insight into thesustainability implications of selected processes as well as thecontributing factors.5. Method for Manufacturing Process Evaluation5.1 To evaluate the sustainability of manufacturing pro-cesses for improvement, organizations need to develop andimplement a consistent, organizat

22、ion-wide sustainability mea-surement process. The following sections provide guidelinesfor such a process.5.2 Setting Sustainability Objective:5.2.1 Sustainability assessment starts with a statement of thesustainability goals, including the area of opportunity to beaddressed. In this step, an organi

23、zation identifies the opportu-nities from several perspectives: organizational,environmental, external and internal stakeholders.NOTE 2To define the objective(s), various methods for data collectionand analysis can be used, such as interviewing managers, sustainabilityauditors, the study of past sus

24、tainability reports of the organization, orvarious external guidelines.5.3 Identifying Indicator:5.3.1 Indicators provide a context to measure, analyze, andscore the sustainability aspects of manufacturing processes.Indicators can be defined internally, or can be selected fromvarious indicator repos

25、itories.5.3.2 Indicators are selected based on the sustainabilityobjective, such as energy consumption for efficiency or CO2equivalent emissions for climate considerations. Factors thatmay influence indicator selection include the type of product,type of process, type of resource, quantity of resour

26、ce, finalreporting format, budget, approvals required, market, timeavailability, or other external guidelines.5.3.3 An indicator is characterized by the following attri-butes:5.3.3.1 NameThe word(s) for the distinctive designationof an indicator.5.3.3.2 DefinitionThe statement expressing the essenti

27、alcharacteristics and function of an indicator.5.3.3.3 Measurement TypeThe type of an indicator (quan-titative or qualitative).5.3.3.4 Unit of MeasureThe unit value of the indicator.5.3.3.5 ReferencesCitable documents of existing indicatorset(s) or specific indicator(s), based on which an indicator

28、isadopted from existing set(s) or newly developed.5.3.3.6 Application LevelThe level in a hierarchical orga-nization at which the indicator is applied.5.3.4 Using this information, an organization may also setup their own sustainability indicators based on their businessstrategies.5.4 Identifying Pr

29、ocess(es):5.4.1 Process identification establishes the specific processor set of processes that contribute to the identified indicator.5.4.2 Process identification should be guided through the setobjectives and the associated indicators selected.5.4.3 The process or set of processes under evaluation

30、should fall within the governing process or production plan.The order in which a process is selected or an objective isdetermined will vary depending on the production plan andorganizational goals.5.4.4 Relevant documentation should be collected and mayinclude:5.4.4.1 Engineering drawings.5.4.4.2 Ro

31、uting sheets with several processes.5.4.4.3 Safety data sheets.5.4.4.4 Quality control plans that provide product and pro-cess specifications.5.4.4.5 Setup sheets for individual machines. Setup sheetsinclude the operating parameters of the machine.5An explanation of CO2equivalent emissions and an ov

33、dentifying Evaluation Metrics:5.5.1 Evaluation metrics associate the process or processesto be evaluated with the identified indicator. Metrics provide ameasure for which indicators can be evaluated.5.5.2 Evaluation metrics are dependent on the selectedindicator (example: waste for material efficien

34、cy and energyusage for energy efficiency), the equipment and processesbeing evaluated, and the availability of data.5.5.3 Evaluation metric identification should take into con-sideration the capabilities and limitations of available measure-ment equipment.NOTE 3Identifying the appropriate metric is

35、important, as the metricmay influence the boundary conditions of the evaluation process and theuncertainty of the results.5.6 Setting Boundary Conditions:5.6.1 Boundary conditions limit the scope and constrain theextent of the evaluation. Boundary conditions may include thephysical boundaries associ

36、ated with identified equipment ortime-related boundaries. Physical boundaries may be refineddepending on the definitions of the unit manufacturing pro-cesses. Time-related boundary conditions establish the periodof time for which measurements are taken or evaluation resultsare valid.5.6.1.1 The prod

37、uction plan associated with the process orprocesses of interest will outline and establish the boundaries.Boundaries of the evaluation may be set at the supply chain,the company, the plant level, or within the plant at themanufacturing process level.5.6.1.2 A manufacturing process can be described a

38、s asystem that consists of multiple subprocesses within theboundaries. A simple boundary example consists of a singleunit manufacturing process and the designated manufacturingequipment.5.6.1.3 An example boundary application on a system is theassembly of a hand-held power tool. The boundary willdet

39、ermine how the unit is characterized, for instance, aboundary may be placed around the entire assembly process forthe power tool, or the boundary may be placed around asubassembly of the power tool.5.6.2 Establishing Process Boundaries:5.6.2.1 The production plan may include handling andstorage acti

40、vities associated with the production process, thusincluding the peripheral equipment and storage facility. Ex-amples include the material handling systems used to transportwork-in-process (WIP) between manufacturing processes, theracks and storage for WIP and inventory, and a portion of theheating

41、and cooling of the facility. The organization maychoose not to include the peripheral equipment and storagefacility in the study.5.6.2.2 Examples of boundary conditions that should beconsidered:(a) Upstream and downstream information from the supplychain.(b) Materials handling between processes.(c)

42、Allocation of energy consumption in the facility (forexample, heating, ventilation, and air conditioning-HVAC).(d) Impact of peak versus off peak energy consumption.(e) Process monitoring at the machine level.5.6.2.3 Indicators and corresponding metrics will influencehow boundary conditions are defi

43、ned. For example, whenevaluating for material efficiency, boundary conditions may beaffected by considerations such as use of co-products, by-products, reworked, recycled or scrap material. When evaluat-ing for energy efficiency, considerations may includecogeneration, alternate sources of energy, e

44、nergy audits, orreclamation of waste energy from processes (that is, usingexhaust heat from one process as energy input for a differentprocess).5.6.3 Establishing Unit Manufacturing Processes:5.6.3.1 The identification of unit manufacturing processeswill (1) determine where measurements should be ta

45、ken inorder to calculate process-specific metrics, and (2) provideboundaries for analytical models that can be developed usingwell-defined unit manufacturing processes.5.6.3.2 Production processes can consist of multiple unitmanufacturing processes. In these scenarios, the sustainabilityperformance

46、of a manufacturing process can be evaluated as anaggregation of the performance of unit manufacturing pro-cesses. The unit manufacturing processes identified within theestablished boundary conditions should either directly orindirectly relate to the chosen indicator.5.6.3.3 Examples of boundary cond

47、itions that should beconsidered at the unit manufacturing process level include:(a) Identifying useful energy, that is, the energy consumedin making the part or product.(b) Incorporating waste heat generated during processing.(c) Distinguishing material removed from a part or productas waste or recy

48、cled.(d) Evaluating sub-processes within the process at efficien-cies other than 100 % efficient.5.6.4 Supply Chain Considerations:5.6.4.1 Production planning may consider manufacturingresources outside of the plant through an established supplychain. The boundary conditions of the supply chain must

49、 becarefully considered. Resource data can be collected fromoutside plants along the supply chain.5.6.4.2 It is possible to include external data from down-stream and upstream processes, that is, consideration of theemissions associated with the electricity used by the processes.5.6.4.3 It is important that wherever boundaries are createdthat they remain consistent throughout the evaluation process.5.7 Identifying Input and Output Parameters:5.7.1 Each unit manufacturing process has one or moreinput and output parameters associated with it.
