Which one of the following is an improvement type heuristic algorithm for computerized layout design technique?1. Systematic layout planning (SLP)2. Computerized relative allocation of facilities technique (CRAFT)3. Computerized relationship layout planning (CORELAP)4. Plant layout analysis and evaluation technique (PLANET)

Answer» Correct Answer - Option 2 : Computerized relative allocation of facilities technique (CRAFT)

Explanation:

CRAFT algorithm was originally developed by Armour and Buffa. It is an improvement algorithm.

  • It starts with an initial layout and improves the layout by interchanging the departments pairwise so that the transport cost is minimized.
  • The algorithm continues until not further interchanges are possible to reduce the transportation cost.
  • The result given by CRAFT is not optimum in terms of minimum cost of transportation.
  • But the result will be good and close to optimum in the majority of applications. Hence, CRAFT is mainly a heuristic algorithm.

CRAFT requirements :
1. Initial layout
2. Flow data or Load summary
3. Cost per unit distance
4. Total number of departments
5. Fixed departments, Number of such departments Location of those departments.
6. Area of departments.
