Investigating the Appropriate Service Model in the Iranian Liquefied Gas Industry: A World Class Approach

The goal of the researcher is to analyze the proper model and components of after-sales services for the world-class Iranian gas industry to compete. For this purpose, after reviewing the theoretical foundations, four models that were more right to the industry were selected, based on Lotsma logarithmic scale and using Rembrandt software, questionnaire formulation, distribution and analysis. In fact, the use of the Rembrandt model, which is considered a hierarchical model, has been used to discuss the weaknesses of the hierarchical model to check the proper after-sales service model. 30 industry experts have been selected to complete the researcher-made questionnaire and the reliability of the questionnaire has been validated by Rembrandt software. The research results show that the Tetraclass model as a global after-sales service model with key, essential, added and secondary factors is very effective in this industry. Simmons, parsley and olive oil models were also given top priority. Response-free, reliability, features or features, compliance, service expectation, pricing are the main sub-components of the selected models.
