Machines are a key element in the production system and their failure causes irreparable effects in terms of cost and time. In this paper, a new multi-objective mathematical model for dynamic cellular manufacturing system (DCMS) is provided with consideration of machine reliability and alternative process routes. In this dynamic model, we attempt to resolve the problem of integrated family (par...

The Cell formation problem in Group Technology (GT)/ Cellular Manufacturing Systems (CMS) is being researched for the past forty years and many solution methodologies have been developed for solving this "hard" problem. One of the areas where there is little progress is in software development for cell formation. A software provides an opportunity to appropriately apply theoretical algorithms t...

abstract        background and objective: the formation of urinary infection by uropathogenic e.coli needs   numerous virulence factors and biofilm formation is among these factors. bacteria that form biofilms express phenotype traits that appear according to the bacteria type. cellulose is an important compound on the outside of e.coli causing bacterial cell-cell reactions and connection to no...

The machine-part cell formation problem consists of creating machine cells and their corresponding part families with the objective of minimizing the inter-cell and intra-cell movement while maximizing the machine utilization. This article demonstrates a hybrid clustering approach for the cell formation problem in cellular manufacturing that conjoins Sorenson’s similarity coefficient based meth...

The design of cellular manufacturing system (CMS) involves many structural and operational issues. One of the important CMS design steps is the formation of part families and machine cells which is called cell formation. In this paper, we propose an efficient algorithm to solve a new mathematical model for cell formation in cellular manufacturing systems based on cell utilization concept. The p...
