Designing a sustainable supply chain using an integrated analytic network process and goal programming approach in quality function deployment

Sustainable supply chain management (SSCM) provides economic, social end environmental requirements in material and service flows occurring between suppliers, manufacturers and customers. SSCM structure is considered as a prerequisite for a sustainable success. Thus designing an effective SCM structure provides competitive advantages for the companies. In order to achieve an effective design of this structure, it is possible to apply quality function deployment (QFD) approach which is successfully applied as an effective product and system development tool. This study presents a decision framework where analytic network process (ANP) integrated QFD and zero-one goal programming (ZOGP) models are used in order to determine the design requirements which are more effective in achieving a sustainable supply chain (SSC). The first phase of the QFD is the house of quality (HOQ) which transforms customer requirements into product design requirements. In this study, after determining the sustainability requirements named customer requirements (CRs) and design requirements (DRs) of a SSC, ANP is employed to determine the importance levels in the HOQ considering the interrelationships among the DRs and CRs. Furthermore ZOGP approach is used to take into account different objectives of the problem. The proposed method is applied through a case study and obtained results are discussed.

Intelligent manufacturing and environmental sustainability

The definition of sustainability which is generally adopted is: “meeting the needs of the present generation without compromising the ability of future generations to meet their own needs” (World Commission on the Environment and Development, 1987. Brundtland report). The EU MDG7 report, describes environmental sustainability as: “…meeting current human needs without undermining the capacity of the environment to provide for those needs over the long term…” (UN, 2005a). Over the past decade public concern about sustainable development has profoundly transformed attitudes and to a lesser extent practices in manufacturing industries. A sustainable approach to design and engineering involves evaluating where a product or system has the greatest environmental impact and then prioritising strategies which reduce that impact. There is hardly any industry sector in which the management of environmental sustainability is not of significant relevance. The degradation of pristine ecosystems, global warming, and unprecedented energy usage, has become key issues for all of earths ‘tenants’. It is essential that all facets of design and manufacturing take action on environmental sustainability concerns through appropriate strategies, and endeavour to implement standards such as the ISO 14001, and accommodating related legislation as a foundation for sustainable manufacturing. This paper discusses the sustainability challenges of the industrial world, the sustainable management issues they face, and the strategies they might employ, while maintaining corporate responsibility and gaining competitive advantage.     

A nonlinear observer design for an activated sludge wastewater treatment process

This paper treats the problem of estimating simultaneously the state and the unknown inputs of a class of nonlinear discrete-time systems. An observer design method for nonlinear Lipschitz discrete-time systems is proposed. By assuming that the linear part of this class of systems is time-varying, the state estimation problem of nonlinear system is transformed into a state estimation problem for LPV system. The stability analysis is performed using a Lyapunov function that leads to the solvability of linear matrix inequalities (LMIs). Performances of the proposed observer are shown through the application to an activated sludge process model.     

A contradiction solving method for complex product conceptual design based on deep learning and technological evolution patterns

Contradictions caused by the various design constraints present increasing challenges to efficiency and innovation in product development. TRIZ provides Inventive Principles (IPs) and Contradiction Matrix that are the most frequently applied in conflict resolution. However, the high-level abstraction and subjective selection of IPs inhibit achieving the transformation process from paradoxical states to physical structures. To fill this gap, a contradiction solving method by integrating deep learning and technological evolution patterns for product conceptual design is proposed, which illustrates the mechanism of contradiction transition from the perspective of system evolution and supplies a systematic and model-based design approach. Firstly, generic engineering parameters are extracted to define the underlying contradictions transformed from critical defects which are found out through function modeling and root-conflict analysis. Then, a fully-connected deep neural network with excellent performance is developed to uncover the non-linear relationships between engineering parameters and evolution patterns. Finally, an evolution tree based on the predicted patterns is constructed to visualize transformation potentials of a technical system and help designers generate innovative specific solutions. In addition, a case study concerning design conflict resolution for beat-up system of three-dimensional tubular weaving machine is used to validate the adaptability and reliability of the proposed approach.
