The subject of the present study is production scheduling taking into consideration the payment of penalties. The purpose of production scheduling is to allocate limited resources over time to perform a group of activities. Therefore, the aim of the research was to develop an appropriate schedule in a production system that deals with issues such as various interruptions in production, lack of forecasting of raw materials required and time required for production, inability to decide on the composition of production which will lead to damages caused by delay and work stoppage. If the work is completed after the delivery date, there will be a penalty for late payment due to customer dissatisfaction, a contractual penalty or loss of credit. Reliability engineering must ensure that components and subsystems meet the defined requirements over a period of time. The research design was based on solving standard sample problems. In this regard, this research provided a mathematical model for multiple purpose scheduling. The scheduling problem was solved in the form of a reliability problem. Findings showed that solving the problem of production scheduling in the form of reliability performed well in terms of finding optimal solutions. The reliability of the system was also confirmed in 14 sample problems.
