Development of Cellular Manufacturing Model for Product Varieties Management in Industries

The increasing demand of customers in terms of speed of service and reduced cost at higher quality has generated a new platform on which manufacturing companies compete. The purpose of this report is to develop a Cellular Manufacturing Model, which is actually an application of group technology, which has been described as a stepping stone to achieving world class manufacturing status. Required strategic decisions were identified and the mathematical models required were developed. The models were integrated to form the logic with the aid of a flow chart. The formulated model was implemented with a software using C – Sharp (C-#). The identified strategic decisions which are the input variables are: Quantity input total cost rate, waiting time, setup time, work start time, delivery time, cycle time and average product demand. Processing this data using the developed mathematical models resulting into total productivity, production lead time, unit cost, cycle time, and delivery time determination. Statistical analysis of both input and out data was carried out the correlation coefficient (r) of the data was 0.95 which gives a very strong relationship. Graphs were also drawn to represent the output quantity against value added time and also graph of delivery ready goods against total cost rate. At the end of it all, a useful way of implementing this aspect of cellular manufacturing was suggested.
