The research examines the status of flexibility in production systems in four categories: one-machine-one part, many-machines-one-part, one-machine-many-parts, and many-machines-many-parts. A company with higher flexibility is expected to develop a variety of products at low cost, high quality, and with short cycle time. An important component in design and development of flexibility in a production system is the establishment of appropriate flexibility measures. A flexibility measure or a set of flexibility measures is used to determine the level of flexibility in a typical production system at a given situation. In order to achieve appropriate control over flexibility over time, the best option is to measure and evaluate it in quantitative terms. In this research, models pertaining to various flexibility dimensions are developed and applied in a typical bearing manufacturing company to quantify the level of flexibility.","PeriodicalId":306645,"journal":{"name":"International Journal of Sustainable Design","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132998677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Set-up time is one of the vital parameters used in any manufacturing industry and is a form of necessary input to every machine or workstation. The SMED method, originally developed by the Japanese industrial engineer Shigeo Shingo, for reducing the time to exchange dies gives a really straightforward approach to improve existing set-ups and to easily obtain a reduction of up to 60% (Singh and Khanduja, 2010). Since the last decade, people have also realised that by improving ‘a posteriori’ situation a lot of problems can be prevented during the design phase of the equipment itself. This paper completes the set of design rules specifically for foundry dies and tooling, for their shorter set-ups. Efforts have been made to sustain the existing design of tooling on the basis of Poka-yoke principles. A specific set-up tool kit has also been unleashed in the text, and based on practical experiences a number of useful tips have been quoted for formulation of an efficient and effective set-up procedure, strategically.","PeriodicalId":306645,"journal":{"name":"International Journal of Sustainable Design","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125598161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Core differences between this 'sustainable hydrogen economy' (SHE) and the original hydrogen economy (HE) proposed in the early 1970s are discussed. In transport, rather than posing a binary choice between hydrogen fuel cell and battery electric vehicles, it is argued that the old maxim of 'horses for courses' should be followed, with complementary deployment of these two technologies depending on the transport service to be supplied. Other key features of SHE are the use of distributed bulk hydrogen storages for season-to-season storage on electricity grids, and as a strategic energy reserve. The conduct of detailed energy-economic-environmental modelling is recommended to evaluate the SHE vision in particular national and regional contexts, and hence globally.","PeriodicalId":306645,"journal":{"name":"International Journal of Sustainable Design","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123863489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, the global ELV recovery industry is seeking to identify a proper treatment technology to recover the non-metal fraction of an ELV, and consequently, extend the ELV recovery rate above the typical value of 70% to 75%. The proposed decision-making support framework consists of four main stages: benchmarking study, development of the primary set of options, evaluation of options, and systems modelling. Stages one to three of the proposed conceptual framework are focused mainly on identifying the sustainable ELV treatment technology/strategy based on industry best practice. The last stage is focused on business sustainability assessment of the selected treatment option. The combined outcome of these stages is the integrated sustainable treatment option (ISTO). This means that both the treatment option and the business based on the selected treatment option are sustainable. This paper details the framework stages and the results of an associated case study illustrating the application of the developed framework in an Australia context. The paper also discusses those characteristics that distinguish the proposed conceptual framework from other types of decision-making support tools such as life cycle assessment (LCA).","PeriodicalId":306645,"journal":{"name":"International Journal of Sustainable Design","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130275290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, before end-of-life products can be recycled, end-of-life disassembly needs to be in place. It entails large amounts of capital expenditure and time. Besides this, product designers also do not have experience in disassembling and recycling to determine the impact of various design aspects on difficulty at the disassembly stage. Therefore, there is a need for a tool to analyse the disassemblability and recyclability.
