MWorks TOPSIS Implementation and Usage in Multi-Criteria Decision-Making
TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is a widely used method for multi-criteria decision analysis. In the context of MWorks, this technique can be implemented effectively to evaluate multiple alternatives based on various criteria.
Overview of TOPSIS Methodology
The core idea behind TOPSIS involves determining an ideal solution and an anti-ideal solution from given data points. The optimal choice will have the shortest distance to the ideal solution while being farthest away from the anti-ideal one. This approach ensures that decisions are made considering both positive and negative aspects simultaneously[^1].
Steps Involved in Implementing TOPSIS within MWorks Environment
To implement TOPSIS using MWorks:
- Data Normalization: Normalize all criterion values so they fall into comparable ranges.
- Weight Assignment: Assign weights reflecting relative importance among different criteria.
- Ideal Solutions Calculation: Compute weighted normalized matrices to derive positive and negative ideal solutions.
- Distance Measurement: Calculate Euclidean distances between each alternative and these two reference points.
- Closeness Coefficient Computation: Determine closeness coefficients indicating how close each option lies towards the best possible outcome compared with worst-case scenarios.
- Rank Ordering Alternatives Based On Closeness Coefficients
Below shows Python code snippet demonstrating basic steps involved when applying TOPSIS algorithm inside MWorks environment:
import numpy as np
def topsis(data_matrix, weight_vector):
# Step 1 & 2: Data normalization followed by weighting assignment
norm_data = data_matrix / np.sqrt((data_matrix**2).sum(axis=0))
w_norm_data = norm_data * weight_vector
# Step 3: Find out Positive Ideal Solution(PIS) and Negative Ideal Solution(NIS)
pis = w_norm_data.max(axis=0)
nis = w_norm_data.min(axis=0)
# Step 4: Distance calculation
d_pos = ((w_norm_data - pis)**2).sum(axis=1)**(1/2)
d_neg = ((w_norm_data - nis)**2).sum(axis=1)**(1/2)
# Step 5: Relative closeness computation
cc = d_neg/(d_pos+d_neg)
return cc
This function takes input parameters including data_matrix
representing performance metrics across options under evaluation along with corresponding weight_vector
. It returns relative closeness scores which help rank order potential choices objectively according to their proximity toward desired outcomes versus undesired ones[^3].
