Computer Aided Layout Planning For Manufacturing Industries Of Ethiopia (case In Kotebe Metal Tools Factory)

Layout planning has been considered as one of the vital areas for improving performance of rnany business process. Its main concern is reducing cost by maximizing adjacency of highrninteraction components of a system or reducing material handling cost or distance betweenrnthe components. Taking KMTF’s layout as a case, this study considered three approaches ofrnlayout design. rnThe first approach utilized the improvement of the existing layout. Section wise exchangernand machine wise exchanges are made to the current layout to arrive at a better layout thanrnthe currently being used layout. Making the exchange section wise and then using the rnmachine arrangement obtained by this method to be further improved by machine wise rnexchange is observed to give better layout than improving the current machine arrangements.rnThe exchange has been made according to CRAFT improvement routine. rnThe second approach has been done to construct a new layout for KTMF sections usingrnCORELAP construction routine and then improving the constructed layout using CRAFTrnimprovement routine. But the current layout is observed to be better starting point forrnimprovement using improvement routine than the constructed layout. This shows the currentrnlayout is good but can further be improved by using improvement routines. To show thernapplicability of the approach another study published by Yugoslav Journal of OperationsrnResearch has been explained. This approach is suggested to be used in planning a newrnlayout.rnThe third approach introduced is the roll forging machine into the improved layout. Thernapproach assumes the Roll forging machine is used by four products and the dies for the fourrnproducts are brought together with the machine. Accordingly location of the new Rollrnforging machine has been obtained using single facility layout problem. rnFinally, it is concluded that the current layout is a good initial layout for improvement usingrnCRAFT algorithm and a better layout is achieved by improving the current layout.rnFurthermore, construction routine followed by improvement routine is concluded to be goodrnmeans of arriving at good layout in initial design of layouts. The improved layout and Rollrnforging are recommended for KMTF shop floor.
