Lean performance evaluation of manufacturing systems: A dynamic and innovative approach

Lean performance evaluation of manufacturing systems: A dynamic and innovative approach

Lean manufacturing has become an important avenue for both academics and practitioners in recent times. Many organizations around the world have attempted to implement it but the lack of a clear understanding of lean performance and its measurement will contribute to the failure of lean practices. There are many papers, articles, and reports that address lean techniques and tools, but few studi...

Performance evaluation of cellular flexible manufacturing systems: A decomposition approach

In a cellular flexible manufacturing system, a majority of the part types manufactured by the system require machining in a single cell only. However, a few part types (called rare parts) need processing in two or more cells. It is precisely the intercell movement of these rare parts that leads to weak interaction among the otherwise independent cells. We show how this structure can be exploite...

the role of application of dynamic assessment approach in improvement of iranian efl writing performance at different language proficiency levels

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...

Lean Manufacturing for High Performance

Design of a New Mathematical Model for Integrated Dynamic Cellular Manufacturing Systems and Production Planning

This paper presents a new mathematical model for integrated dynamic cellular manufacturing systems and production planning that minimizes machine purchasing, intra-cell material handling, cell reconfiguration and setup costs. The presented model forms the manufacturing cells and determines the quantity of machine and movements  during each period of time. This problem is NP-hard, so a meta-heur...
