This paper deals with manufacturing cell formation considering the dynamic behavior of the production system. First, we discuss the importance of taking into account the dynamic aspect of the problem that has been poorly studied in the related literature. We argue that by considering a multi-periodic planning horizon, we can tackle the problem according to two strategies: passive and active. Th...

objective: the aim of this study was to investigate the effect of laser assisted hatching on the development and quality of vitrified-warmed 4-cell stage mouse embryos. materials and methods: the vitrified-warmed 4-cell mouse embryos were divided into two groups: control group (without laser assisted hatching) and experiment group (with laser assisted hatching). all embryos in both groups were ...

We present a mathematical model of an individual cell to expand the simulation invadopodia formation three-dimensional (3D) domain for more realistic complexity. Simulating replication in order it be biologically relevant is important since helps us understand cancer invasion and metastasis better as well giving some insight into investigating ways stop spread this fatal disease. Invadopodia fo...

Although most previous studies on cell formation have involved the assignment of parts and machines to cells, in recent years workers has also been considered taken into account human factor. An important step for successful implementation a Cellular Manufacturing System is decide appropriate groups parts, machines, then assign them cells. Consideration skills processing enhanced performance. I...

One of the designs of cellular manufacturing systems (CMS) requires that a machine population be partitioned into machine cells. Numerous methods are available for clustering machines into machine cells. One method involves using a similarity coefficient. Similarity coefficients between machines are not absolute, and they still need more attention from researchers. Although there are a number o...
