BACKGROUND It is not clear whether the purported association of leanness with cancer of the oral cavity and pharynx was due to cancer-related weight loss or to the influence of factors associated with leanness. PATIENTS AND METHODS Seven hundred fifty-four incident cases of cancers of the oral cavity and pharynx and 1775 controls, admitted to hospital for acute, non-neoplastic diseases, in It...

The strategy of organizational lean production emphasizes on increasing efficiency, quality improvement and cycle time reduction by eliminating non-value added activities (MUDA). This paper presents a comprehensive approach based on data envelopment analysis (DEA), fuzzy DEA (FDEA), fuzzy cognitive map (FCM), Decision Making Trial and Evaluation Laboratory (DEMATEL) and Analytic Hierarchy Proce...

At the last decade of the 20th century, Womack et. Al introduced Lean concept to the industrial world. Since 1990 up to now, existed studies mostly have focused on lean production in the step of manufacturing, but in this research leanness concept has developed in the plant life cycle. In this paper leanness concept will be described as elimination of wastes in the phases of investment, plant d...

Purpose – The purpose of this paper is to present a dynamic model to measure the degree of system’s leanness under dynamic demand conditions using a novel integrated metric. Design/methodology/approach – The multi-stage production system model is based on a system dynamics approach. The leanness level is measured using a new developed integrated metric that combines efficiency, WIP performance ...

In spite of thevast researchpublishedon leanmanufacturing systems in several disciplines in the last decade, the concept remains underdeveloped for two reasons. First, it lacks a generally accepted definition. Different authors define lean in terms of its objectives, which vary, overlap and differ in different firms. Second, no study has developed a systematic and relative measure of lean produ...

Women participating in a wide range of competitive sports are at higher risk of developing eating disorders, menstrual irregularities and osteoporosis, which are generally referred to as the 'female athlete triad'. The objective of this study was to determine the prevalence of female athlete triad and factors associated with this condition among athletes participating in different sports. A tot...

The purpose of this paper is to empirically investigate the relationship between lean production implementation and financial performance. Particular emphasis is placed on the mediating role of inventory leanness in deriving the financial performance benefits commonly associated with lean production. Moreover, the interaction among different lean practice bundles in affecting financial and inve...
