Liver is a vital organ in human being. Liver disease has basically four different stages of its progression namely hepatitis or steatosis or hepatosteatosis (Stage 1), fibrosis (Stage 2), cirrhosis (Stage 3), and hepatocellular carcinoma (Stage 4). The diagnosis of a specific stage of liver disease can be made by clinical laboratory imaging or liver stiffness finding. The goal of the present paper is to analyze the performance of human liver to enhance survivability. For the purpose, a stochastic model has been developed for the human liver considering liver disease at different stages of its progression and liver transplantation at cirrhosis stage. Using Markov process and regenerative point technique, survivability measures are obtained and analyzed. Sensitivity and relative sensitivity analyses are also carried out to judge the impact of various parameters.
