- In the global market, customer demands changes rapidly. Manufacturing companies need to meet the demands to keep competitive. Therefore, manufacturing processes constantly need to be changed. The process change is challenging because it involves different actors across the company, especially for international companies that have globally distributed operations.Manufacturing process change is carried out by production engineers and needs to consider the needs and requirement of all actors in the manufacturing system. To this end, guidelines for manufacturing system design and cross-functional team meetings for concept design assessmentare utilized. While the meeting takes place, such meetings require resources to be available in parallel and advanced planning to come to fruition. Thus making the concept design iteration loop considerably longer if inputs are to be collected frequently.This paper presents an approach that utilizes a collaborative tool developed in Unity. It integrates 3D scanned factory data with proposed process changes to provide sufficient context to every stakeholders involved. Thus, to facilitate better understanding and communication of the ongoing changes. It will improve every process change on its design, implementation, and future maintenance. The challenges of implementation and evaluation of the collaborative tool are discussed.

- There is a lack of structured methodologies to support stakeholders in accessing the sustainability aspects for e-waste management. Moreover, the increasing volume of electronic waste (e-waste) and the availability of automated e-waste treatment solutions demand frequent reconfigurations of facilities for efficient e-waste management. To fill this gap and guide such ongoing developments, this paper proposes a novel methodological framework to enable the assessing, visualizing and comparing of sustainability impacts (economic, environmental and social) resulting from changes applied to a facility for e-waste treatment. The methodology encompasses several methods, such as discrete event simulation, life cycle assessment and stakeholder mapping. A newly-developed demonstrator for sorting e-waste is presented to illustrate the application of the framework. Not only did the methodology generate useful information for decision making, but it has also helped identify requirements for further assessing the broader impacts on the social landscape in which e-waste management systems operate. These results differ from those of previous studies, which have lacked a holistic approach to addressing sustainability. Such an approach is important to truly measure the efficacy of sustainable e-waste management. Potential future applications of the framework are envisioned in production systems handling other waste streams, besides electronics.

- Sustainability assessments are dependent on accurate measures for energy, material, and other resources used by the processes involved in the life cycle of a product. Manufacturing accounts for about 1/5 of the energy consumption in the U.S. Minimizing energy and material consumption in this field has the promise of dramatically reducing our energy dependence. To this end, ASTM International [1] has formed both a committee on Sustainability (E60) and a Subcommittee on Sustainable Manufacturing (E60.13). This paper describes ASTM's new guide for characterizing the environmental aspects of manufacturing processes [2]. The guide defines a generic representation to support structured processes. Representations of multiple unit manufacturing processes (UMPs) can be linked together to support system-level analyses, such as simulation and evaluation of a series of manufacturing processes used in the manufacture and assembly of parts. The result is the ability to more accurately assess and improve the sustainability of production processes. Simulation is commonly used in manufacturing industries to assess individual process performance at a system level and to understand behaviors and interactions between processes. This paper explores the use of the concepts outlined in the standard with three use cases based on an industrial example in the pulp and paper industry. The intent of the use cases is to show the utility of the standard as a guideline for composing data to characterize manufacturing processes. The data, besides being useful for descriptive purposes, is used in a simulation model to assess sustainability of a manufacturing system.
