Abstarct: Lack of resources and increased user consumption have encouraged energy activists towards multi-generation. Therefore, in the present work, a quadruple production system of electricity, hydrogen, fresh water, and cooling is presented. Gas turbine parts (two GTs) and steam and organic Rankine cycles to produce power, پمE to produce hydrogen, RO desalination to produce fresh water, and compression refrigeration to achieve cooling were applied. Thermal recovery of hot gases in two Rankine cycles in order to increase power production and application of generated electricity as a utility for producing fresh water, hydrogen, and cooling is only a part of the basic aspects of this work. The system and its components have been examined from the point of view of three applied analyzes of energy, exergy and exergoeconomic (3E). In this regard, two commercial engineering programs THERMOFLEX for thermal simulation and MATLAB to develop the analysis code have been used. THERMOFLOW's extensive and powerful library of GTs and its suitability for modeling thermal systems have made it popular. The biggest part of the plant is gas turbine that located upstream for other equipment. The high accuracy in the calculations shows the high quality of the developed model. The net production power of the system is 379.5 MW with energy conversion efficiency of 50.03%. The shares of GTs, steam and organic Rankine sectors are 67.15%, 29.67%, and 3.18%, respectively. Monthly analysis illustrates that the highest power production occurs in January. R141 is the best organic fluid from the point of view of the 3E analyzes performed. 8.95 kg/h of hydrogen is produced with an energy efficiency of 59.15%. The recovery ratio of RO is 49.39% and it produces 500 tons/day of fresh water. In the refrigeration section, 18.3 kg/s of cool water will be obtained at a temperature of 5.67℃. The best exergy efficiency is observed in the AC. More than 79% of the exergy destruction of the system occurs in two GTs, while the cost rate of exergy destruction of this part is 74.70%. The highest cost of electricity production in July will be 37.64 $/MWh. In the case with R141b fluid in the ORC, the operating cost rate of the system is 14226.5 $/h. Finally, the sensitivity analysis of the integrated system to nine working quantities were performed.
