The methods/models that can be used for both improvement-type and construction-type layout plans/designs are the Pairwise Exchange Method and Graph-based Method.
The Pairwise Exchange Method is a versatile approach that can be applied to both improvement-type and construction-type layout plans/designs. In improvement-type layouts, the method iteratively evaluates and exchanges the positions of pairs of elements to optimize the existing layout's performance. On the other hand, in construction-type layouts, the method can be used to iteratively generate new layouts by exchanging elements based on predefined rules or objectives.
Similarly, the Graph-based Method is well-suited for both improvement-type and construction-type layout designs. It involves representing the layout as a graph, where nodes represent elements and edges represent spatial relationships between them. In improvement-type layouts, the method can analyze the graph and reconfigure the connections between nodes to enhance the layout's efficiency. In construction-type layouts, the graph can be used as a blueprint to create new layouts by adding or modifying nodes and edges based on specific design criteria.
While the Multi-floor Plant Layout Evaluation (MULTIPLE), Layout Optimization with Guillotine Induced Cuts (LOGIC), and Mixed Integer Programming (MIP) methods are valuable for certain types of layout planning and optimization, they may not be as flexible in addressing both improvement-type and construction-type layout scenarios. Therefore, the Pairwise Exchange Method and the Graph-based Method stand out as the suitable choices for meeting the requirements of both layout plan improvement and construction.
