Business process optimization from single timestamp event log

Time-cost optimization (TCO) may be defined as a process to identify suitable construction activities to get the minimum duration of process and minimum additional cost which is needed. CPM crashing project is one of method to sole the time-cost optimization. But CPM crashing project need some data to speeding up the process business whereas in reality there are a lot of data which is represent using single timestamp event log which does not provide. There for this paper represents a method to get data which is use to crashing project. The data is got from averaging time execution of each activity in case in event log. Then to crashing the project this paper use linear programming to get minimum duration and minimum additional cost.
