Production system life cycle: an inside story

Abstract: The life cycle of production system depicts the progress of production system from the inception to the termination of system. This paper explores the different stages of production system life cycle with the view to introspect the decisions made in each stage along with their key consideration. Besides this, quality enabled factors have been identified in each stage of the production system life cycle, which will help in making the accurate decision in different stages of the production system life cycle. In each sub–system of production system, identification of major activities/sub–activities along with role of concerned department would help to analyse and manage the stages of production system in a better way.

Modelling the barriers affecting design and implementation of reconfigurable manufacturing system

Abstract: Today’s volatile market, which is influenced by global competition and changing customers’ demands, has made the manufacturing companies to look for new manufacturing systems which can fulfil their requirements for global competition. Reconfigurable manufacturing systems (RMSs) are those systems which are capable to meet the requirements of modern manufacturing industries. But adoption and implementation of RMSs is not an easy task. There are certain barriers which not only influence the implementation process but also influence each other. The main objective of this paper is to identify and analyse these barriers. In the present work, these barriers have been identified through the literature, their ranking is done by a questionnaire-based survey and interpretive structural modelling (ISM) approach has been utilised in analysing their mutual interaction.

Effect of Lean Principles on Organizational Efficiency

Abstract: In India, the manufacturing sector is striving hard to generate revenues and this is ongoing for the last one decade. This aspect of generating funds is dependent on two major factors i.e. reduction in product manufacturing cost, and enhancing the product quality to satisfy the customer needs. The production cost can be reduced by improving the design and through incorporating the newest version of materials. The improved version of materials will positively add value to the product quality and thereby attract the customers. On the other hand, the product quality can increased through application of systematic and statistical data analysis tool especially Lean, Six Sigma, SCM, JIT, TPM etc. in the manufacturing sector. This may further results in high labour efficiency. The paper comprises of literature review of published paper in various reputed journals on the concept of Lean manufacturing. "Lean" is a production process which encompasses the expenditure of all the resources to accomplish a goal and creating of value to end customer through eliminate the wastes. The paper reveals that the goal of Lean is creation and maintenance of a production system, which runs repetitively, day after day, week after week in a manner identical to the precious time period. The continuous and smooth flow, earlier delivery, reduced cost and better design are the outcomes of the systems.

Design of an Ontology Based Adaptive Crawler for Hidden Web

Abstract: Deep Web is content hidden behind HTML forms Since it represents a large portion of the structured, unstructured and dynamic data on the Web, accessing Deep-Web content has been a long challenge for the database community This paper describes a crawler for accessing Deep-Web using Ontologies Performance evaluation of the proposed work showed that this new approach has promising results

Fatigue Life Assessment of 65Si7 Leaf Springs: A Comparative Study

Abstract: The experimental fatigue life prediction of leaf springs is a time consuming process. The engineers working in the field of leaf springs always face a challenge to formulate alternate methods of fatigue life assessment. The work presented in this paper provides alternate methods for fatigue life assessment of leaf springs. A 65Si7 light commercial vehicle leaf spring is chosen for this study. The experimental fatigue life and load rate are determined on a full scale leaf spring testing machine. Four alternate methods of fatigue life assessment have been depicted. Firstly by SAE spring design manual approach the fatigue test stroke is established and by the intersection of maximum and initial stress the fatigue life is predicted. The second method constitutes a graphical method based on modified Goodman's criteria. In the third method codes are written in FORTRAN for fatigue life assessment based on analytical technique. The fourth method consists of computer aided engineering tools. The CAD model of the leaf spring has been prepared in solid works and analyzed using ANSYS. Using CAE tools, ideal type of contact and meshing elements have been proposed. The method which provides fatigue life closer to experimental value and consumes less time is suggested.
