Question

Which one of the following is an improvement type heuristic algorithm for computerized layout design technique?

• A. Systematic layout planning (SLP)
• B. Computerized relative allocation of facilities technique (CRAFT)
• C. Computerized relationship layout planning (CORELAP)
• D. Plant layout analysis and evaluation technique (PLANET)

Hint:

CRAFT is a widely used algorithm to improve facility layouts by minimizing transportation costs through an iterative improvement process.

Answer 1

The Correct Option is B

The CRAFT (Computerized Relative Allocation of Facilities Technique) is an improvement-type heuristic algorithm used to optimize the layout of facilities in a manufacturing plant. It works by evaluating and improving the initial layout through the rearrangement of facilities based on the distances between them, minimizing the total transportation cost. CRAFT iteratively improves the initial solution and can be considered a type of heuristic algorithm that works through local optimization. Here’s why the other techniques listed are not improvement-type algorithms: - Systematic Layout Planning (SLP) is a methodology that organizes the layout design process but is not an improvement-type heuristic algorithm.
- Computerized Relationship Layout Planning (CORELAP) uses the relationship matrix to arrange the facilities in the most efficient manner, but it is not an improvement heuristic; it is more of a systematic approach.
- Plant Layout Analysis and Evaluation Technique (PLANET) helps in analyzing the plant layout but does not employ improvement heuristics like CRAFT. Thus, the correct answer is (B).
