Unquestionably, selection of proper technique is a very important step in the layout design. Every available technique has its own benefits and limitations. There is no method which can be a alchemy solution the entire layout problem. The selection of technique is dependent on the plant constraints, size of firm and objective of design. The final layout given by the computer program may not be best design, as computer programs are optimization techniques based on certain algorithms which may not be practical or those not able to take care of all the eventualities. The computer programs are better than the traditional methods as they form an array of layouts very quickly and are not dependent of capabilities of the designer. Performance of each alternate layout can be evaluated by simulation and one can select the most appropriate layout by comparing the performance of the each layout considering the objective of the layout design.
