If an operation included in the route definitions is related to the previous operation, the Previous Operation Relations option located in the right mouse button menu is used when the operation is defined. The overlap rate between the operation in the line and the operation(s) required to be listed right before the operation in the line is recorded on the previous operation relations window.
Operations for which the Overlapping Rate is specified as 100% start at the same time. Operations for which the overlapping rate is specified as 0% start when the previous operation is completed.
More than one operation can be required to be listed right before the operation in the route line. In such cases, these operations are selected from the list opened on the Previous Operation column, and their overlap rates are specified.
