This article's objectives are to assess the current state of the textile and apparel industry's value chain by breaking it down into its component parts, identify industry challenges based on its various subsectors, and offer solutions for the industry's development and completion of its value chain in order to increase its competitiveness. This industry can be considered important due to its low capital intensity and ability to meet all three of the country's goals of industrial production, development (employment), and foreign exchange; Its 8.2% share of industrial enterprises (10 employees and above), 7.3% share of industrial employment, and 3.5% share of fixed capital formation demonstrate this. The study's conclusions demonstrate that the main issues facing Iran's textile and apparel sector are related to the value chain's fragility as well as the inadequacies of the regulations that are supposed to encourage it. The development of the textile and clothing industries in Iran is facilitated by policies and executive mechanisms that include re-engineering the value chain's structure to maximize the benefits of internal content, facilitating the transfer of technology and equipment to this sector, and outfitting it with ancillary and support services. This is what recommended in this article.

The global trend towards natural applications in the fields of production and transportation is growing rapidly, and factors such as low cost, safety, availability, environment, and the development of technology and its application, especially in gas turbines, have made the product an alternative to petroleum fuels. Be. Many of the technological ways on the market explore the challenges and opportunities of using natural gas with the aim of identifying relevant productivity paths. As one of these solutions, in this article, a model for selecting the best fuel in the natural value chain in Iran is introduced from four options: compressed natural gas, natural gas, dimethylator and Gas- To- Liquid (GTL). First, based on a comprehensive study, fuel selection indicators were identified. Then, using Delphi technique and with the help of relevant experts, the indicators were screened and the final 20 cases were selected. In the next step, the indices were ranked, which was achieved through a group agreement between experts with a Kendall matching coefficient of 0.808. In order to convert rank into weight, a Rank Order Centroid (ROC) technique was used. Finally, with the weights of the indicators as well as the four options mentioned above, the CoCoSo technique is taken to determine the superior fuel. According to the results, liquefied natural gas is currently the best option for the country. And in the next rank, compressed natural gas is placed. The facts of the world confirm the accuracy of the results obtained.
