Book Description
The demand from consumers for more sustainable products, and the need to comply with government regulations motivates manufacturers to evaluate their operations for opportunities to reduce environmental impact and improve economic competitiveness. Manufacturers have actively improved the sustainability performance of their products through the use of sustainability assessment methods and tools. Recently however, manufacturers have struggled to maintain the necessary gains in energy and material efficiency due to the inadequacy of current, mature sustainability assessment methods and tools. This situation is compounded since new methods and tools continue to be developed for specialized applications, leading to inaccurate assessments in other domains. Overcoming these barriers requires standardized sustainability assessment methods and tools that are ready for use (plug-and-play) and contain accurate manufacturing process-level information. The research conducted herein posits that this barrier can be overcome through the advancement of information modeling and the automation of manufacturing system assessments. Thus, manufacturing process models would be composed to preserve information flows. Therefore, the work presented attempted three goals: 1) Assess the barriers to sustainable manufacturing through a review of the academic literature and roundtable meetings with industry; 2) Propose an information modeling framework to trace, capture, and control information flows within a composed manufacturing system for sustainability assessment; and 3) Develop a desktop application implementing the framework to accelerate the sustainability assessment of composed manufacturing systems. Results from realizing the framework through an underpinning XML Schema and overlaying graphical user interface indicate that the presented approach would be useful in conducting sustainable manufacturing assessments. Future work should focus on improving the robustness of the information framework and the resulting XML Schema by incorporating validation content and structure for improved quality and composability of unit manufacturing process models.

Book Description
"Sustainable manufacturing methods make it possible to develop products in ways which minimize negative environmental impacts, conserve energy and save natural resources whilst being economically sound. The concepts of sustainability in manufacturing being are still fairly broad, in scope, and need to be more focused and firmly established at the process, machine or factory levels. This project proposes a structure for manufacturing with a main objective to develop a sustainability framework which encompasses various production processes. Structured information models for the seamless flow of information across the design and manufacturing domains, for selected manufacturing processes, are defined. The thesis work identifies key performance indicators (KPIs) for the assessment of manufacturing sustainability and performs analysis of selected unit manufacturing processes and their sub-processes with the aim of proposing a methodology for determining science-based measurements of the manufacturing processes affecting these KPIs. The theoretical foundations established are then used to develop a model that could evaluate sustainability of selected manufacturing processes and their respective process plans providing a basis for inter-process comparison and selection of the most sustainable process plan. The proposed framework is presented in form of a manufacturing planning computer-based package which is designed to to consider different influencing factors such as product information, part geometry, material related physical and processing properties and the manufacturing equipment operating data. The thesis presents a number of case studies which have been published in international journals. The case studies present estimates of the manufacturing sustainability KPIs for a number of production methods. These estimates have been verified with available shop floor data. The work in the thesis makes it possible to establish manufacturing industry equipped to deal the challenges of the future when sustainability will be the major factor up on which the quality of success will be determined." -- Abstract.

Book Description
Traditionally, environmental impacts of man made products have been determined by performing a life cycle assessment (LCA) on the product. As the name implies, LCA is usually covers the entire life of the product in a so-called "cradle-to-grave" assessment. In determining environmental impacts over the whole product life, LCA's are reasonably adequate. However, in providing detailed impacts on a particular phase of life, LCA's are lacking. Detailed assessments are important because very few stakeholders have influence over a product during all phases of life. Stakeholders need detailed impact assessments in their particular phase of life. More detailed assessments give stakeholders more information that can be used for better environmental management (EM) and more environmentally benign operations. In many LCA's, the manufacturing phase of life has been over-generalized and over-simplified because of its relatively small environmental impact, as compared to other phases of life. Nevertheless, certain stakeholders, such as manufacturing companies, need detailed impact information for the manufacturing phase of life so that they can create a more sustainable manufacturing process. Most traditional LCA's use a case-based approach, which was deemed to be inadequate. For these LCA's, the information provided for each case is often quite detailed and specific. However, this makes the assessment less flexible, limiting the quality of the assessment to the degree that the current scenario matches the existing cases. In order to make a more user-specific assessment, a model-based approach was used. To give the model flexibility, a parametric model was created based on mathematical equations that represent various parts of the manufacturing process. To give the model structure, an activity-based costing (ABC) approach was used. Using the ABC structure, the manufacturing process was broken down into activities, each of which was characterized by mathematical models. Large models would be difficult to construct and simulate by hand, so a model was built with the aid of a computer. The modeling language SysML (Systems Modeling Language) was used to create an object-oriented model of the manufacturing process, using the ABC structure. SysML defines overall properties and behaviors of the various elements in the model, while the plug-in tool ParaMagic was used to execute the model via a Mathematica Solver. The model computes carbon dioxide emissions, energy consumption, and waste mass generation for a particular manufacturing scenario. The goal of the model was to quantify environmental impact factors in order to aid manufacturing stakeholders in EM. The overall goal of the research was to determine whether an activity-based, object-oriented model was a valid approach, and whether the computer-aided tools adequately implemented this approach. Findings show that SysML is capable of modeling large and complex systems. However, due to some limitations of Paramagic, only some of SysML's capabilities were utilized. Nevertheless, Paramagic is capable of extracting information out of a manufacturing model built in SysML, and solving parametric relations in Mathematica in a timely manner. Timely solutions of complex models are critical for stakeholders keeping a competitive edge.

Book Description
The 18th CIRP International Conference on Life Cycle Engineering (LCE) 2011 continues a long tradition of scientific meetings focusing on the exchange of industrial and academic knowledge and experiences in life cycle assessment, product development, sustainable manufacturing and end-of-life-management. The theme “Glocalized Solutions for Sustainability in Manufacturing” addresses the need for engineers to develop solutions which have the potential to address global challenges by providing products, services and processes taking into account local capabilities and constraints to achieve an economically, socially and environmentally sustainable society in a global perspective. Glocalized Solutions for Sustainability in Manufacturing do not only involve products or services that are changed for a local market by simple substitution or the omitting of functions. Products and services need to be addressed that ensure a high standard of living everywhere. Resources required for manufacturing and use of such products are limited and not evenly distributed in the world. Locally available resources, local capabilities as well as local constraints have to be drivers for product- and process innovations with respect to the entire life cycle. The 18th CIRP International Conference on Life Cycle Engineering (LCE) 2011 serves as a platform for the discussion of the resulting challenges and the collaborative development of new scientific ideas.

Book Description
More recently, interest in designing products and manufacturing processes with major consideration given to the resources used and waste produced over the entirety of product/process life cycle, viz. sustainable manufacturing has increased. Unlike design and manufacturing process development activities that generally have access to a wealth of material information, sustainability assessment activities are generally made difficult by lack of a centralized source of information to incorporate sustainability knowledge into current manufacturing life cycle strategies. Even though considerable research has been accomplished in sustainable manufacturing domain, its application to real life problems is known to be in the early stages due to complexity in information representation, model compositions, system integrations, and computation. Moreover, isolated activities of process planning within the gate-to-gate life cycle can lead to localized solutions in sustainability assessment. Integrating operation plans and process plans provides globalized sustainable and productive solutions in the manufacturing gate-to-gate life cycle.This thesis, first, presents an attempt to understand these complexities for building material information model by addressing the requirements for defining a high-level material information model for sustainability that can capture this information across different life cycle stages as well as primary stakeholders. Second, the performance of job shop manufacturing is often related to diversified activities that impact sustainability and productivity. Process and operation plans are particularly considered as the main activities that significantly impact different key performance indicators. The research proposed a systematic methodology for supporting manufacturing decision-making regarding sustainability and productivity assessment by integrating these plans.In the first stage the different ways in which materials and material information influence the decision-making process were analyzed. For this purpose information modeling techniques were employed to generate manufacturing scenarios. Activity models were generated and analyzed to collect and categorize key concepts towards constructing a Materials Information Model for Sustainability. The analysis helped in identifying locations where materials factor into the decision-making process, the key information requirements that help build a material information model for sustainability. In the second stage of this research, a systematic methodology was developed for enabling the sustainability and productivity performance assessment for integrated process and operation plans at the machine cell level of manufacturing systems. Selection of processes and operations is accomplished through building a Multi-Criteria-Decision-Making formulation. This formulation enables the combined assessment of sustainability and productivity in selecting the optimum process and operation plans. Analytical Hierarchical Process (AHP) is employed to address the problem of conflicting key performance indicators during process planning. Discrete event simulation (ArenaTM) and optimization techniques (heuristic search algorithms in OptQuest) are combined to determine the set of inputs out of a number of possible planning scenarios and their interactions that optimize system sustainability and productivity performances. The possibility of applications of the approach to real-world production is demonstrated through a case study that uses the proposed methodology to analyze and understand manufacturing floor-level scenarios.
