lean cell operates itself by what is called standard operations. job rotation is known as the standard operation of a lean cell. however, researchers have not studied job rotation to demonstrate the performance of a lean cell. job rotation decisions affect lean cell performance through influencing the manner in which tasks assigned to the selected operators during several rotation periods. this...

The uncritical adoption of production-line manufacturing practices (such as "lean thinking") into work design processes in hospitals creates a fundamental tension between the production of health care and protection of the patient. There is scant evidence that re-engineering health care services in line with industrial models increases their efficiency. Indeed, reducing the richness of health c...

A unique line of Duroc pigs was established by intensive selection for increased lean growth efficiency. The objective of this study was to determine the influence of this selection strategy on fresh pork quality traits. Two lines of Duroc pigs originating from the same foundation herd were evaluated. One line was selected for lean growth efficiency over five generations (Select line), and the ...

The six-sigma systems can promote the enterprise competitive ability, such as pursuing cost improvement, promoting quality, the customer’s satisfaction and valid strategy performance. This paper explored the synergies resulting from the combination of state-of-the art quality initiatives, lean and design for Six Sigma, and develop an integrated SCOR with lean and design for Six Sigma methodolog...

Introduction: Accidents in the workplace hurt people and sometimes cause death. One of the ways to prevent occupational accidents is to change the behavior and attitude of people towards safety. The present study was conducted to investigate the effect of the lean approach on the promotion of safety culture in Sarv combined cycle power plant of MAPNA exploitation. Materials and Methods: In thi...

lean manufacturing is a systematic approach to identifying and eliminating wastes (non-value added activities) through continuous improvement by conveying the product at the pull of the customer in pursuit of production. in a more basic term, more value with less work. since lean manufacturing eliminates many of the problems associated with poor production scheduling and line balancing, lean ma...

An urgent need in American health care is improving quality and efficiency while controlling costs. One promising management approach implemented by some leading health care institutions is Lean, a quality improvement philosophy and set of principles originated by the Toyota Motor Company. Health care cases reveal that Lean is as applicable in complex knowledge work as it is in assembly-line ma...

Gas motion within the cylinder is one of the major factors that control the combustion process in spark ignition engine. It also has significant impact on heat transfer. Both the bulk gas motion and the turbulence characteristics of the flow are important and governing the overall behavior of the flow. An arrangement for obtaining a stratified charge, using port injection, is proposed for a ...
