AbstractIn this research the model of multiple products lot sizing with random demand on a single facilitywith service level constraint has been developed The model considered with both static dynamicstrategy and static strategy Also an efficient method has been used to solve it The model ofmultiple products lot sizing is NP Hard and as a result solving this model in big dimensions is notpossible so the SA Simulated Annealing method has been used to solve the model Generally maximizing the expected profit or minimizing the expected cost as objective function hasbeen used in the lot sizing models but there are other important objective functions One of theseobjective functions is maximizing the probability of achieving a budgeted profit In this dissertationthis objective function has been surveyed in one product case and then has been developed to oneproduct and multiple periods and multiple product and multiple periods The SA method has beenused for solving the model The SA answers for some example problems have been compared withoptimal answer or lower bound The results show the efficiency of the SA
