Exploring barriers in lean implementation

Abstract: Purpose – The purpose of this paper is to present an analysis of research on lean focusing on barriers in its implementation through a systematic literature survey. Design/methodology/approach – A literature survey of peer-reviewed journal articles, survey reports, master theses, doctoral theses and paradigmatic books with managerial impact is used as the research methodology. Findings – The findings derived from the evaluation of the publications analyzed have led to the identification of 24 lean barriers. The success of lean implementation will not be entirely based on application of appropriate tools and techniques alone but also on the top managements' involvement and leadership, workers' attitude, resources and the organizational culture. Research limitations/implications – This literature survey is primarily focused on lean implementation in the manufacturing sector. Practical implications – This paper explores barriers for successful lean implementation and provides a concise description of the bar...

Development of layered laminate bamboo composite and their mechanical properties

Abstract: Dry bamboo culms of Dendrocalamus strictus were processed into thin laminas and cold pressed using epoxy resin to produce layered bamboo epoxy composite laminates. Mechanical properties of layered bamboo–epoxy composite laminates including tensile strength, compressive strength, flexural strength and screw holding capability have been evaluated. Mode of failure were identified at macroscopic level as suggested in ASTM standard and their mechanism were examined at microscopic level using SEM analysis of fractured surfaces under different type of tests.

Development of framework for sustainable Lean implementation: an ISM approach

Abstract: The survival of any organization depends upon its competitive edge. Even though Lean is one of the most powerful quality improvement methodologies, nearly two-thirds of the Lean implementations results in failures and less than one-fifth of those implemented have sustained results. One of the most significant tasks of top management is to identify, understand and deploy the significant Lean practices like quality circle, Kanban, Just-in-time purchasing, etc. The term ‘bundle’ is used to make groups of inter-related and internally consistent Lean practices. Eight significant Lean practice bundles have been identified based on literature reviewed and opinion of the experts. The order of execution of Lean practice bundles is very important. Lean practitioners must be able to understand the interrelationship between these practice bundles. The objective of this paper is to develop framework for sustainable Lean implementation using interpretive structural modelling approach.

Comparative study of mechanical properties of bamboo laminae and their laminates with woods and wood based composites

Abstract: In the present work, an attempt has been made to study the mechanical properties of bamboo so as to explore the possibility of its’ usage as structural material in place of wood. Dry bamboo culms of Dendrocalamus strictus were processed into thin laminae and cold pressed using epoxy resin to produce LBCs. Mechanical properties of bamboo laminae and their LBCs have been evaluated under different loading conditions. Similar to wood, there is better correlation for stiffness than strength of bamboo laminae under tensile, compressive and flexural loading but there are fewer correlations in mechanical properties of LBCs owing to random selection of laminae from different locations and also because of addition of epoxy during preparation of LBCs. Comparisons with woods indicate that average strength of bamboo laminae obtained under different loading conditions is better than softwoods and comparable with hard woods. It is inferred from the results that bamboo can be utilized for fabrication of LBCs. Furthermore, tests results and comparisons clearly show that LBCs can be used as an alternative to wood and wood based composites for structural purposes.

Stiffness and strength analysis of four layered laminate bamboo composite at macroscopic scale

Abstract: Dry bamboo culms of Dendrocalamus strictus were processed into thin laminas and cold pressed using epoxy resin to produce four layered laminated bamboo epoxy composites (LLBCs). Experimental and theoritical values (stiffness and strength) of LLBCs, prepared from middle region laminae, have been evaluated under tensile loading and using rule-of-mixture respectively. Experimental values of LLBCs are closely resembles with theoretical values. Further, a hypothetical four layered unidirectional laminated bamboo composites (HLLBCs) have been proposed where their stresses and strains obtained using constitutive equation of laminate at macroscopic scale are lower than experimental failure limit of LLBCs. This indicates that proposed LLBCs behaves like fibrous composites which are presently in use for a variety of structural applications.
