Differences in legislation and markets for recycled materials result in the national implementation of distinct end-of-life treatment strategies. This paper presents a comparative analysis of the boundary conditions in Belgium and Japan that cause the adoption of diverse treatment strategies for the rapidly increasing number of end-of-life flat screen TVs. In addition, both treatment strategies are evaluated from an ecological and economic perspective and opportunities for improvement are identified. © 2013 CIRP.

Many applications of Biologically-Inspired Design (BID) are well-known and research is increasingly focusing on methodologies towards systematic BID. However, currently no ideation tool exists that is able to leverage the large textual biological resources in a scalable way to propose a selection of biological strategies that are interesting for a specific design problem under focus. This paper first identifies the main bottleneck preventing the realization of such a scalable BID ideation tool by analyzing the state-of-the-art in systematic BID. It is observed that most work focuses on developing detailed models of, both biological and engineering systems, which enable support during knowledge transfer between the two domains. However, the automated instantiation of these models for a large collection of biological strategies currently remains an open question and domain experts are necessary to complete this time-consuming and expensive task. Therefore, a new approach is proposed that uses a conceptual representation of the biological domain to identify candidate biological strategies as input for the transfer phase.

During the past decades, several joint maintenance and inventory optimization systems have been studied in literature. Compared to the sequential optimization of both models, Kabir and Al-Olayan (1996) reported a remarkable influence on total cost due to their joint optimization method. This review focuses on models that include cost and optimization parameters related to both maintenance and inventory. The purpose of this paper is to review the pertinent literature on joint maintenance and inventory optimization models for non-repairable parts and suggest possible gaps. A classification based on the following seven sets of criteria is made: inventory policies, maintenance characteristics, delays, multi-echelon networks, single-unit versus multi-unit systems, objective function and optimization techniques. © 2012 Elsevier B.V.

Equipment maintenance and system reliability are important factors affecting the organisations ability to provide quality and timely services to customer. While maintenance remains an important function to manufacturing, it is only recently that attempts have been made to quantify its impact on equipment performance. In this research, an approach of linking maintenance with equipment performance is developed using simulation modelling. The modelling approach involves defining probabilistic models and assumptions affecting system performance, such as: the probabilistic model for the initial failure rate/intensity of the equipment; the probabilistic model for the system deterioration and corresponding effect; the probabilistic model for the random times of corrective maintenance (CM) and preventive maintenance (PM) that takes into the account the types of maintenance plans/policies and the potential dependency between CM and PM times; and the probabilistic model for the random effects of CM and PM on the reliability of the equipment. Using a continuous manufacturing equipment, the model is used to analyse the impact of deterioration, failures and maintenance (policies, timing and efficiency) on equipment performance. It is shown that modelling the effect maintenance provides a basis of evaluating maintenance efforts with the potential application in performance evaluation and decision support while investigating opportunities for manufacturing equipment performance improvement. © 2013 © 2013 Taylor & Francis.

This paper aims to provide a systematic overview of the state of the art in energy and resource efficiency increasing methods and techniques in the domain of discrete part manufacturing, with attention for the effectiveness of the available options. For this purpose a structured approach, distinguishing different system scale levels, is applied: starting from a unit process focus, respectively the multi-machine, factory, multi-facility and supply chain levels are covered. Determined by the research contributions reported in literature, the de facto focus of the paper is mainly on energy related aspects of manufacturing. Significant opportunities for systematic efficiency improving measures are identified and summarized in this area. © 2012 CIRP.

Although Biologically-Inspired Design (BID) is gaining popularity, state-of-the-art approaches for systematic BID are still limited by the required interactive work which is proportional to the applied biological database size. This interactive work, depending on the adopted methodology, might encompass model instantiation for each strategy in the biological database, classification into a predefined scheme or extensive result filtering. This contribution presents a first scalable approach to systematic BID with the potential to leverage large numbers of biological strategies. First, a focused webcrawler, based on a combination of Support Vector Machines (SVM), continuously searches for biological strategies on the Internet. The solution to this needle-in-ahaystack task is shown to produce biological strategies interesting for cross-domain Design-by-Analogy (DbA). These resources are then automatically positioned into Ask Nature's well-known Biomimicry Taxonomy; a 3-level hierarchical classification scheme that enables designers to identify biological strategies relevant to their specific design problem. This paper details the architecture of the proposed system, and presents results indicating the feasibility of the applied approach. Copyright © 2012 by ASME.

This paper presents a generic and flexible reference data model meant as the blueprint of the database component of information and decision support systems related to different types of biomass-based supply chains (e.g. first to fourth generation biomass for production of bioenergy and biomaterials). The data model covers the biomass types and handling operations as characterised by their attributes and mutual relationships resulting from a life cycle inventory analysis. The data model enables the identification of the possible operation sequences in the specified chain. This functionality is demonstrated in a case study in which biomass from tall herb communities and mesotrophic grasslands is supplied for biogas or compost production. A comparative analysis has pointed out that the data model includes the required object types to add specific attributes of biomass supply chain simulation and optimisation models (such as spatial and temporal dimensions). © 2016 Elsevier Ltd.

Although Biologically-Inspired Design is gaining popularity, state-of-the-art approaches for systematic Biologically-Inspired Design are still limited by the required interactive work which is proportional to the applied biological database size. This interactive work, depending on the adopted methodology, might encompass model instantiation for each strategy in the biological database, classification into a predefined scheme, or extensive result filtering. To address this bottleneck, a scalable approach to systematic Biologically-Inspired Design, with the potential to leverage large numbers of biological strategies, is presented. Central to the approach are a set of Organism Aspects that form a conceptual representation of the biological domain. Inspired by the theory of inventive problem solving, this conceptual representation is an abstraction that facilitates knowledge reuse. The proposed Organism Aspects information structure supports a number of new systematic innovation functionalities aimed at assisting designers looking for bio-inspiration. Amongst these functionalities are the following: identification of a set of organisms relevant for the designer, a relevance sorted list of biological documents, and in-text annotation to facilitate cross-domain analogy identification. © 2015 The Authors.

Lean Thinking and Six Sigma are quality management tools developed in an industrial context, where they have proven their usefulness for decades. More recently, these tools entered health care. Quite some literature on the application of these tools in health care has appeared since. This paper reviews this literature; more than 120 papers are studied and classified according to the nature of the paper: review, case study, strategy or tool description. Many case study papers were found. For these papers further analysis was made on the focus quality issue, the tools used and the area of implementation.

Probability estimation of machine usages is an essential task to the development of an intelligent device/environment. In this paper, we propose a generic framework to the task using the sliding window technique and incremental feature selection. The methodology is applied to a real-life dataset of office printers and the performances of different standard classifiers in supervised learning are compared. We conclude that Logistic Regression (LR) outperform other classifiers and is appropriate for the proposed framework. The use of Generic Bayesian Network (GBN) classifier is also promising, if combined with feature reduction methods. © 2014 IEEE.
