23. Planning / Operations Interaction Operation Mode is Built From Planning Information Operation Mode is Built From Planning Information Operation uses the same Network, Planning Characteristics and Projects as the Planning Mode. Operation uses the same Network, Planning Characteristics and Projects as the Planning Mode. Operation Mode intent is to provide an “Operation Diversion” for each project within the Planning Mode to be applied to the WISE Analysis Engine. Operation Mode intent is to provide an “Operation Diversion” for each project within the Planning Mode to be applied to the WISE Analysis Engine. Operation Diversion is calculated in the Operation Mode: Operation Diversion is calculated in the Operation Mode: Operational Diversion is made available to the user in the Project Information Section once the Base and Project Scenarios have been run for a given Project. This can be accessed by the following: Operational Diversion is made available to the user in the Project Information Section once the Base and Project Scenarios have been run for a given Project. This can be accessed by the following: Select Planning Tab -> Project Info Tab -> “Go To Project” for the Project desired. “Operation Supplied” will display the amount Select Planning Tab -> Project Info Tab -> “Go To Project” for the Project desired. “Operation Supplied” will display the amount
