Non-linear optimization of critical path method

摘要

Time and Cost Optimization (TCO) may be described as a process to identify appropriate construction activities to get the minimum duration of process and minimum additional cost which are needed. Critical Path Method (CPM) crashing project is one of methods to solve the time and cost optimization. But CPM crashing project needs some data to speed up the process business and in reality there are a lot of data which are represented using double timestamp event log. Therefore this paper represents a method to get data which are used in the crashing project. The data are obtained from average execution of activity duration in each case of event log. Then, to do the crashing project, this paper uses non-linear modeling to get minimum activity duration and minimum additional cost.
