Familles de Produits et Ilots de Fabrication: Le Cas de Machines Mutiiples

A methodology for cellular manufacturing design

“…This methodology allows selection of those machines which have to be kept in the workshop, assigns parts to machines, and yields a partition of parts and machines. Its application to some examples found in the literature turns out to be as good or even better than (as in the case of Meguelati (1988), Garcia et al (1985) and Harhalakis et al (1990)) the results previously obtained in terms of intercell moves; a solution being always obtained in a few seconds (Fig. 14:t,.…”

“…In addition to the definition of the maximum number of machines to be assigned to cells, as in Ballakur and Steudel (1987), Kusiak (1988)and Gunasingh and Lashkari (1989),we also choose to define a minimum as well as a minimum and maximum number of parts. Contrary to Gunasingh and Lashkari (1989), who solve the assignment problem using the given families of parts, and Garcia et al (1985) and Meguelati (1988), who define an initial partition for the parts, followed by a machine selection and assignment phase, our methodology begins with a machine selection and an assignment phase: We want to use resources in the best way. For this purpose we first attempt to find the best matching between parts and a subset of the available machines in the shop.…”

“…The number of cells is set a priori, unlike Ballakur and Steudel (1987) who compute it as part of the procedure. The initial data matrix takes into account the durations of the operations, as in Garcia et al (1985), Ballakur and Steudel (1987), Meguelati (1988) and Kusiak (1988), whereas Garcia and Proth (1986), Kusiak (1987), Rajagopalan (1987,1989), Kumar and VaneIIi (1987), Gunasingh and Lashkari (1989), Shtub (1989) and Wei and Kern (1989) employ 0/1 matrices. In addition to the definition of the maximum number of machines to be assigned to cells, as in Ballakur and Steudel (1987), Kusiak (1988)and Gunasingh and Lashkari (1989),we also choose to define a minimum as well as a minimum and maximum number of parts.…”
