| Abstract | The purpose of this study is to develop an efficient model to find machine - part families in
Cellular Manufacturing Systems. The study is composed of two parts. First part deals with the
multiple objective model for forming simultaneous machine - part families and assigning operators
to machines in a cellular manufacturing system. A Mixed - Integer Goal Programming approach is
used as the methodology. Branch and bound method was used as the solution methodology.
LINDO (Linear INteractive Discrete Optimizer ) software package was used to solve the goal
programming model. The second part deals with developing a heuristic to form machine - part
families. As the problem of finding machine - part families can be treated as a problem involving
multi attribute decision making, one of the important technique known as Preference Ranking
Organization METHod for Enrichment Evaluations (PROMETHEE) was used. PROMCALC
software package was used for evaluations.
Management objectives of a manufacturing facility such as higher productivity, better
quality, higher efficiency, flexibility of manufacturing, better control of production, minimizing
costs, maximizing resource utilization and meeting the demand are transformed into shop flow
level objectives in the model by maximizing operator similarity to machines, operator skills, cell
utilization, machine similarity, part similarity, and minimizing inter-cell moves, intra-cell moves,
labour costs, etc. Also alternative routings, processing times, processing sequences of parts, part
volumes, machine capacities, number of machines of each type required, due to processing times
of all parts processed on each machine type exceeding the machine capacity, size of cells and
number of cells are considered in the models. The model applications are demonstrated by using
the case of an automobile component manufacturer. |
