4 - Terminology to Support Manufacturing Process Characterization and Assessment for Sustainable Production

Common terminology is essential for accurate communication among researchers, scientists, engineers, and other decision makers. To assist manufacturing process characterization, a common understanding of terminology is imperative for efficient and effective communication in industry; it can also facilitate automation and interoperability of software tools. Manufacturing process characterization enables the assessment and improvement of unit manufacturing processes, products, and systems from a sustain- ability perspective. To develop and implement sustainability-related standards and best practices in industry, naming conventions and definitions of common terms are needed. Presently, many terms used are ill-defined, vague, or overlap in meaning. Although there are ongoing standards efforts related to terminology identification and definition, an identified common set is yet to be developed. The objective of this work was to facilitate ongoing standards development efforts by harmonizing the varied array of terms used to describe production processes. As a result of a review of the literature, a concise set of 47 terms focusing on process characterization and able to describe sustainable production was generated; terms unique to individual production processes were omitted. The terms were orga- nized into six categories to define the overarching concepts: Scope, Boundary, Material, Measurement, Model, and Flow. Definitions of the terms were then derived from the literature in sustainable manufacturing and chemical and process industries, process characterization and planning, organization standards, and life cycle assessment and management. The reported terms and definitions are not unique to sustainable production, and could foster wide- spread use of the concepts to improve the economic, environmental, and social performance of industry. In the future, the terminology described could be standardized through international standards orga- nizations. Manuscript profile

In the last three decades, many researches have been conducted in the field of shape memory polymers, and in the past few years, the interest in research in this field has received a lot of attention. In this study, a comprehensive and complete review of the structure, mechanism, model and applications of this category of polymers has been done. In general, the mechanisms of shape memory polymers are divided into three groups: direct thermal induction, indirect thermal induction, and optical induction, and each has its own switch unit that controls the shape structure. These switches have amorphous and semi-crystalline phase, which are defined in two phase and molecular levels. Also, increasing the mechanical properties, including the strength and toughness of shape memory polymers, is of great importance, which can increase their efficiency. Shape memory polymers can be used in medical, aerospace, textile and other industries. In the textile industry, the electrospinning process is used as a simple and efficient method for the preparation of shape memory polymer fibers and the development of their structure, and the mechanism and method of preparation of these fibers will be investigated. In the last three decades, many researches have been conducted in the field of shape memory polymers, and in the past few years, the interest in research in this field has received a lot of attention. In this study, a comprehensive and complete review of the structure, mechanism, model and applications of this category of polymers has been done. Manuscript profile
