In the 21 st century, manufacturing companies are facing the challenge to remain competitive in global markets by finding a more sustainable approach to product design and manufacturing. This is associated with the main features of companies' competitive landscapes namely, simultaneous cost reduction and quality improvement of the product. It may appear that reaching both these goals together is prohibitively problematic as they are considered by "manufacturing leaders" as opposing objectives. However, much recent research has been done on introducing approaches to delivering low cost, high quality sustainable products based on finding a link between the design or the manufacturing processes and other key elements of sustainability; economic, environmental, and social. Indeed, these approaches often times include limitations such as the lack of integration between the design and manufacturing stages of the product and do not adequately address three key parts of sustainability; economic, environmental, and social. Consequently, these approaches, have a low applicability, and hence few opportunities for success. However, for delivering a sustainable product, the key parts of sustainability, as well as the integration of product design and manufacturing processes must be optimised in terms of one effective measure. This project aims to propose an approach for design and manufacturing sustainability. The combined sustainability index (CSI) is developed as a comprehensive evaluation metric for alternative scenarios of the process and also as a tool that enables decision makers to run optimal processes. The applicability of the CSI has to be tested and verified in a real industrial setting with the aim to improve the sustainability performance by designing a product and the corresponding manufacturing processes for that product. Process optimisation is carried out in terms of the highest CSI score achieved.
Workshop and factory design is one of the most important problems facing companies to enhance their performance and productivity. Facility layout issue is a fundamental fragment of accommodations planning which have a target of organize all manufacturing entities to be located as a facility having the objective to improve manufacturing processes for an organization. The aim of this paper is to study, evaluate and then creating an improved water filter workshop adopting Muther’s (SLP) Systematic Layout Planning Procedure for increasing production and utilizing spaces. The case study in this paper is a practical one for the existing layout in Al-Faris Company in the water filter workshop. The excited layout is studied and manufacturing processes are explored with flow investigation. Activity relationship graph is molded to develop a novel layout alternative. Analyzing by using SLP technique showed that the results for the proposed layout got 341score; while the current layout got only 281 score based on the manufacturing and facility relations. The results show that, the proposed layout is much better than the existing layout of the workshop as significant reduction in the space of material handling and workflow drive and lead to increase the unit production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
