Published by Diane Greer Modified over 3 years ago. Lack human judgment Lack qualitative aspects of Layout Advantages: Rapid What-if Analysis Evaluate large number of alternatives.
If none, choose department randomly Repeat Step 3 until lyout depts. Place departments in layout with DEO and sweep method, do not split if possible.
Score layout with A-based faciluty. Select first department Randomly choose 5 Step 3: Select 6th dept Last dept, choose 6. Discrete Representation CRAFT is an improvement type layout algorithm, therefore the initial starting layout could be: The actual existing layout of the facility Layout developed by another algorithm Distance-Based Objective Pairwise Exchange.
Calculate the inter department rectilinear distances.
faci,ity Calculate the initial cost of the layout by multiplying the from-to matrix with the cost matrix. Update the layout and calculate the new department centroids.
Plant Layout Optimization Using CRAFT and ALDEP Methodology.
The above procedure is repeated until no further reduction in the cost can be obtained. Infeasible Exchange … and so on…. Updated Centroids Dept X Y. Flexible Department Shapes Dummy depts. This is because it cannot shift other departments if the above criterion were not true. Therefore adjacency is a necessary but not sufficient condition for exchange.
CRAFT is flexible with department shapes as long as they are not split. CRAFT is path dependent: The starting layout makes a difference. Produces a set of nested clusters organized as a hierarchical tree Can be visualized as a dendrogram — A tree-like diagram lzyout. Hartl QAP – different space requirements We assume departments, i.
