Sustainability Standards

Standards and regulations are developed and introduced in the market to meet the needs of specific domains. As standards are usually developed by experts within a particular domain, the modeling requirements necessary to represent the information associated with these standards are often not well understood. The lack of clear understanding of information requirements creates an environment where information models can become difficult to produce from standards, and the criteria for complying with these standards may be obscure. The variety of challenges encountered in codifying standards using information models necessitates a carefully devised methodology that takes all areas of the whole enterprise into consideration. This paper presents a methodology for the development of information models to complement and support standards based on the Zachman framework for enterprise architecture. In this paper, we will discuss some of the challenges encountered in modeling information for standards and regulations related to sustainability, and subsequently describe how our approach can be used to address these challenges. We will illustrate our approach by developing an example information model to support RoHS (Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment). This work could lead to the development of software tools and environments for computer aided standards development. Finally, we discuss the advantages and drawbacks of our methodology.

Sustainability Standards

Standards and regulations have become an important part of today’s society. Organizational and geographical dispersions often create situations where manufacturers are forced to meet various standards for a product to reach expanded markets or improve branding. In this paper we propose an approach that provides stakeholders with the means to harmonize a set of standards by identifying similarities and differences between their coverage. Using an analysis approach based on the Zachman framework, we are able to identify both overlaps and gaps that may transpire when analyzing multiple standards associated with a single product domain. To demonstrate our approach, we apply it to a subset of electronics-related sustainability standards. The results are sets of terms that can be used to define the gaps and overlaps between three standards: RoHS (Restriction of Hazardous Substances Directive), WEEE (Waste Electrical and Electronics Equipment Directive), and IEEE (Institute of Electrical and Electronics Engineers) P1680. We then discuss some of the challenges encountered when analyzing these standards. Finally, we briefly discuss the potential for an expanded approach that could assist in the development of domain models and ultimately help identify necessary actions in business processes that will lead to additional standard compliance.

The relevance of the practical implementation of the concept of modeling processes of reflexive management of herd behavior at enterprises, which is reduced to the construction of a conceptual information model, is substantiated. The subject of this research is the toolkit of information modeling of the processes of reflexive management of herd behavior at enterprises. The goal of the article is information modeling of the processes of reflexive management of herd behavior at enterprises. Objective: the construction of an information model of the mechanisms of reflexive management of herd behavior in enterprises in the context of the interrelated functions performed by the system in question and the relationship between data, where, among others, information communications are reflected. General scientific methods are used: system analysis – to determine the features of the mechanism of reflexive management of herd behavior at enterprises, structural (functional) analysis – to identify the main functions of the modeling system of processes of reflexive management of herd behavior at enterprises, information modeling methodology SADT (IDEF0 notation) – to develop information models of a system for modeling the processes of reflexive management of herd behavior at enterprises. The results are obtained: an information IDEF0 model of a system for modeling the processes of reflexive management of herd behavior based on the SADT methodology is developed, which allows you to get a holistic picture of the corresponding processes at enterprises, the basic system concepts of which form the basis of the future information system. Conclusions: formalization, within the framework of the information model of the basic functions of the mechanism of modeling the processes of reflexive management of herd behavior at the enterprise, allows us to describe the basic information connections in a logical, convenient and consistent form, present implementation mechanisms, a set of mathematical models and approaches of the corresponding system.

The design of more sustainable products can be best accomplished in a tradeoff-based design process that methodically handles conflicting objectives. Such conflicts are often seen between, environmental impact, cost, and product performance. To support such a process, this paper proposes the development of an environment where sustainability considerations are explicitly introduced early into the design process. This explicitness is provided by integrating the requirements information of sustainability standards and regulations directly into the design process. The emergence of the semantic web provides an interoperable environment in which the context and meaning of knowledge about the relationships among various domains can be shared. This work presents an ontological framework designed to represent both the objectives that pertain to sustainable design and the applicable sustainability standards and regulations. This integrated approach not only can ease the adoption of the standards and regulations during a design process but can also influence a design toward sustainability considerations. The usefulness of this model integration is demonstrated by an illustrative brake disk rotor and pads case study. The results show that both the standards and criteria may be considered at early design stages by using this methodology. Furthermore, it can be used to capture, reveal, and propagate the design intent transparently to all design participants.

Abstract Solid modeling of objects forms an important task in design and manufacturing. Recent developments in the field of layered manufacturing have shown potential for the physical realization of heterogeneous (multi-material) objects. Thus, there is a need to represent material information as an integral part of the CAD model data. Information models for the representation of product data are being developed as an international standard called STEP (ISO 10303). However, the current application protocols focus on the representation of homogeneous objects only. This paper proposes an information model to represent heterogeneous objects using the information modeling methodology developed for ISO 10303. This will help in providing a uniform base in the development of heterogeneous solid modeling systems. It will also equip the solid modeler with the ability to integrate with other applications and process planning in the domain of layered manufacturing.

Abstract This paper addresses the impact of data fusion on engineering and manufacturing information systems. Data fusion is the integration and analysis of data from multiple sensors to develop a more accurate understanding of a situation and determine how to respond to it. (Sensor fusion, a related term, has a somewhat different, more implementation oriented focus. The difference between these two concepts is addressed specifically in Section 1.) Although data fusion can be applied in many situations, this paper focuses on its application to manufacturing and how it changes some of the more traditional, less adaptive information models that support the design and manufacturing functions. Data fusion requires changes, primarily extensions, to these traditional information models. Engineering models normally address geometry, features, and performance characteristics of a part, while manufacturing models address machine tool characteristics and how they interact with the workpiece and operations scheduling. For data fusion and adaptive control, these models must include the dynamic behavior and interactions between the workpiece and the machine tool. In addition, these models must specify how these dynamic behaviors can be seen and interpreted by various types of sensors (e.g. temperature, pressure, and vibration). On a broader level it must also consider how the machine tools and robots interact within a work cell or production line. The paper consists of four parts. The first section explains what data fusion is and its impact on manufacturing. The second section describes what an information system architecture is and explains the natural language-based information modeling methodology used by this research project. The third section identifies the major design and manufacturing functions, reviews the information models required to support them, and then shows how these models must be extended to support data fusion. The fourth section discusses the future directions of this work.

The variants of the division of the life cycle of a construction object at the stages adopted in the territory of the Russian Federation, as well as in other countries are considered. Particular attention is paid to the exemplary work plan – "RIBA plan of work", used in England. A feature of this document is its applicability in the information modeling of construction projects (Building information Modeling – BIM). The article presents a structural and logical scheme of the life cycle of a building object and a list of works that are performed using information modeling technology at various stages of the life cycle of the building. The place of information models in the process of determining the service life of the building is shown. On the basis of the considered sources of information, promising directions for the development of the life cycle management system of the construction object (Life Cycle Management) and the development of the regulatory framework in order to improve the use of information modeling in construction are given.

The increased diversity and complexity of plastics used in modern devices, such as electrical and electronic equipment (EEE), can have negative impacts on their recyclability. Today, the main economic driver for waste electrical and electronic equipment (WEEE) recycling stems from metal recovery. WEEE plastics recycling, on the other hand, still represents a major challenge. Strategies like design ‘for’, but also the much younger concept of design ‘from’ recycling play a key role in closing the material loops within a circular economy. While these strategies are usually analysed separately, this brief report harmonises them in comprehensive Design for Circularity guidelines, established in a multi-stakeholder collaboration with industry leaders from the entire WEEE value chain. The guidelines were developed at the product and part levels. They are divided in five categories: (1) avoidance of hazardous substances; (2) enabling easy access and removal of hazardous or polluting parts; (3) use of recyclable materials; (4) use of material combinations and connections allowing easy liberation; (5) use of recycled materials. These guidelines are the first harmonised set to be released for the EEE industry. They can readily serve decision-makers from different levels, including product designers and manufacturers as well as policymakers.

Abstract Introduction. Various building information classification systems are used internationally; their critical analysis makes it possible to highlight basic requirements applicable to the Russian classifier and substantiate its structure and composition. Materials and methods. Modern international building information classification systems, such as OmniClass (USA), Uniclass 2015 (UK), CCS (Denmark), and CoClass (Sweden), are considered in the article. Their structure, composition, methodological fundamentals are analyzed. In addition to international classification systems, Russian construction information classifiers are analyzed. Results. The structure of a building information classifier has been developed and tailored to the needs of BIM (building information modeling) and national regulatory and technical requirements. The classifier’s structure complies with the one recommended by ISO 12006-2:2015. Its composition has regard to the requirements that apply to the aggregation and unification of Russian classifiers, and it also benefits from the classifiers developed for and used by the construction industry. The proposed building information classifier has four basic categories and 21 basic classes. Conclusions. The proposed structure and composition of a building information classifier represent a unified and universal tool for communicating building information or presenting it in the standardized format in the consolidated information space designated for information models needed to manage life cycles of major construction projects.

The generalization of the concept of the task in terms of information environments of construction [ISB] is performed. The approach to the presentation of such concepts as construction issues, construction problem, ontology, idea, concept, classification of problems, tasks, directions, objects included in the staging part of the tasks taking into account the specifics of the tasks solved within the developed information technologies in construction issues. The paper defines and investigates on the basis of methods of construction geodesy the actual tasks of construction, design, modeling, monitoring and their totality in the field of construction by means of information theory. An approach to the description of the technical condition of a construction object on the basis of information modeling in the management of the construction process and information modeling within the life cycle is proposed and described. Information modeling is a process, the results of each stage of which, ie information models of the building, differ greatly from each other depending on the stage of the life cycle of the object and the requirements for modeling in solving emerging problems. The construction object strongly depends on the stage of its existence: if during the design it is virtual, and during construction it gradually finds a real embodiment, then at a long stage of operation the building enters a period of stability and is no longer subject to significant changes. An information model is a variable object that depends on the range of tasks to be solved. Using the methods of construction geodesy in the field of construction, the field of problems, class of problems, the concept of the problem, the state of the problem, subtasks, chains of problems, problem solving and the result of solving the problem, the relationship between problems setting the transformation of aggregation, merger, integration. The urgency of the task from a theoretical point of view is determined by the expansion of the ontology of construction as a science, from an applied point of view is determined by the possibility of accurate formalization of regulatory information and documentation in construction.
