Significance and Use4.1 This guide provides a reference to the manufacturing community for the evaluation of environmental sustainability aspectsof manufacturing processes. This guide is intended to improve efficiencies and consistencies of inf
24、ormal methods by providingprocedures for consistent evaluations of manufacturing processes.4.2 This guide describes a procedure to identify parameters and models for evaluating sustainability metrics for a particularprocess. Users of this guide will benefit from insight into the sustainability impli
25、cations of selected processes as well as thecontributing factors.5. Method for Manufacturing Process Evaluation5.1 To evaluate the sustainability of manufacturing processes for improvement, organizations need to develop and implementa consistent, organization-wide sustainability measurement process.
26、 The following sections provide guidelines for such a process.5.2 Setting Sustainability Objective:5.2.1 Sustainability assessment starts with a statement of the sustainability goals, including the area of opportunity to beaddressed. In this step, an organization identifies the opportunities from se
27、veral perspectives: organizational, environmental,external and internal stakeholders.5 An explanation of CO2 equivalent emissions and an overview of common repositories can be found here: http:/www.mel.nist.gov/msid/SMIR/index.html.https:/www.nist.gov/publications/sustainable-manufacturing-indicator
28、repository. Some common repository examples include: Global Report Initiative (http:/www.globalreporting.org), Environmental Indicators for European Union (http:/www.eea.europa.eu/data-and-maps/indicators).E2986 183NOTE 2To define the objective(s), various methods for data collection and analysis c
29、an be used, such as interviewing managers, sustainabilityauditors, the study of past sustainability reports of the organization, or various external guidelines.5.3 Identifying Indicator:5.3.1 Indicators provide a context to measure, analyze, and score the sustainability aspects of manufacturing proc
30、esses.Indicators can be defined internally, or can be selected from various indicator repositories.5.3.2 Indicators are selected based on the sustainability objective, such as energy consumption for efficiency or CO2 equivalentemissions for climate considerations. Factors that may influence indicato
31、r selection include the type of product, type of process,type of resource, quantity of resource, final reporting format, budget, approvals required, market, time availability, or other externalguidelines.5.3.3 An indicator is characterized by the following attributes:5.3.3.1 NameThe word(s) for the
32、distinctive designation of an indicator.5.3.3.2 DefinitionThe statement expressing the essential characteristics and function of an indicator.5.3.3.3 Measurement TypeThe type of an indicator (quantitative or qualitative).5.3.3.4 Unit of MeasureThe unit value of the indicator.5.3.3.5 ReferencesCitabl
33、e documents of existing indicator set(s) or specific indicator(s), based on which an indicator isadopted from existing set(s) or newly developed.5.3.3.6 Application LevelThe level in a hierarchical organization at which the indicator is applied.5.3.4 Using this information, an organization may also
34、set up their own sustainability indicators based on their businessstrategies.5.4 Identifying Process(es):5.4.1 Process identification establishes the specific process or set of processes that contribute to the identified indicator.5.4.2 Process identification should be guided through the set objecti
35、ves and the associated indicators selected.5.4.3 The process or set of processes under evaluation should fall within the governing process or production plan. The orderin which a process is selected or an objective is determined will vary depending on the production plan and organizational goals.5.4
36、4 Relevant documentation should be collected and may include:5.4.4.1 Engineering drawings.5.4.4.2 Routing sheets with several processes.5.4.4.3 Safety data sheets.5.4.4.4 Quality control plans that provide product and process specifications.5.4.4.5 Setup sheets for individual machines. Setup sheets
37、 include the operating parameters of the machine.5.5 Identifying Evaluation Metrics:5.5.1 Evaluation metrics associate the process or processes to be evaluated with the identified indicator. Metrics provide ameasure for which indicators can be evaluated.5.5.2 Evaluation metrics are dependent on the
38、selected indicator (example: waste for material efficiency and energy usage forenergy efficiency), the equipment and processes being evaluated, and the availability of data.5.5.3 Evaluation metric identification should take into consideration the capabilities and limitations of available measurement
39、equipment.NOTE 3Identifying the appropriate metric is important, as the metric may 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 the extent of the evaluation. Bound
40、ary conditions may include thephysical boundaries associated with identified equipment or time-related boundaries. Physical boundaries may be refineddepending on the definitions of the unit manufacturing processes. Time-related boundary conditions establish the period of timefor which measurements a
41、re taken or evaluation results are valid.5.6.1.1 The production plan associated with the process or processes 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 the manufacturingproce
42、ss level.5.6.1.2 A manufacturing process can be described as a system that consists of multiple subprocesses within the boundaries. Asimple boundary example consists of a single unit manufacturing process and the designated manufacturing equipment.5.6.1.3 An example boundary application on a system
43、is the assembly of a hand-held power tool. The boundary will determinehow the unit is characterized, for instance, a boundary may be placed around the entire assembly process for the power tool, orthe boundary may be placed around a subassembly of the power tool.5.6.2 Establishing Process Boundaries
44、5.6.2.1 The production plan may include handling and storage activities associated with the production process, thus includingthe peripheral equipment and storage facility. Examples include the material handling systems used to transport work-in-process(WIP) between manufacturing processes, the rac
45、ks and storage for WIP and inventory, and a portion of the heating and coolingof the facility. The organization may choose not to include the peripheral equipment and storage facility in the study.E2986 1845.6.2.2 Examples of boundary conditions that should be considered:(a) Upstream and downstream
46、information from the supply chain.(b) Materials handling between processes.(c) Allocation of energy consumption in the facility (for example, 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 Ind
47、icators and corresponding metrics will influence how boundary conditions are defined. For example, when evaluatingfor material efficiency, boundary conditions may be affected by considerations such as use of co-products, by-products, reworked,recycled or scrap material. When evaluating for energy ef
48、ficiency, considerations may include cogeneration, alternate sources ofenergy, energy audits, or reclamation of waste energy from processes (that is, using exhaust heat from one process as energy inputfor a different process).5.6.3 Establishing Unit Manufacturing Processes:5.6.3.1 The identification
49、 of unit manufacturing processes will (1) determine where measurements should be taken in order tocalculate process-specific metrics, and (2) provide boundaries for analytical models that can be developed using well-defined unitmanufacturing processes.5.6.3.2 Production processes can consist of multiple unit manufacturing processes. In these scenarios, the sustainabilityperformance of a manufacturing process can be evaluated as an aggregation of the performance of unit manufacturing processes.The unit manufacturing processes id
