Abstract

Objective: The present research aims to develop a Lean Six Sigma model and a resilient supply chain.

Methodology: To develop the Lean Six Sigma model and resilient supply chain using a grounded theory method, interviews with experts were conducted to examine the factors influencing the model's development. Then, the Delphi process and surveys from relevant experts (faculty members, managers of food companies, and supply chain experts) were used to finalize the list of dimensions and components via the grounded theory method and to determine the importance coefficient of each. Finally, the identified input variables were converted into explicit or numerical values using fuzzy inference algorithms by a defuzzification unit. Using the design of experiments technique, the 3^(k-p) method was applied to express the impact of each influencing factor on the output characteristics as a model. Considering the qualitative nature of the research method, the data obtained from the study were analyzed using NVIVO version 11 software in the first step. In the next step, MATLAB software was used for the fuzzy inference section, and finally, MINITAB software was used in the design of experiments section.

Findings: The results showed that all input variables affecting flexibility, capacity, and adaptability were significant at a 95% confidence level. Additionally, Total Quality Management (TQM) had the most significant impact on the variables of flexibility and capacity, while Quality Function Deployment (QFD) had the most significant impact on adaptability.

Conclusion: The proposed model, aiming for integrated information across the food chain, spans from primary agricultural production to the consumer, replacing human mechanisms and potential errors.
