Implementation of Lean Manufacturing Using MCDM-TOPSIS Approach in Switch Gear Manufacturing Industry

Lean manufacturing is an assessment method that assesses productivity and eliminates inefficiency. Manufacturers employ lean manufacturing to maintain the pinnacle of competition by improving the efficiency of their industrial technologies and increasing product reliability. In this work, it was attempted to enhance the operational process of the company that manufactures various features for Medium Voltage (MV) Switchgear manufacturing lines of AEGIS 24 KV by minimizing waste and non-value added process variations using Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) approach and L8 Orthogonal Array (OA). Initially, various factors were considered. Then, combinations of the factors were experimentally arranged as per the L8 OA. Thereafter, the optimal combination is arrived at using the TOPSIS approach, considering the lead time for various combinations.
