Use this sheet to define required breaks for specific vehicles when using the Non-uniform break method.

Each row represents one break requirement for a vehicle. A vehicle may have multiple break entries if needed.

Unlike the Uniform break method, each break can have its own set of allowable break locations. These locations are defined in the Non-uniform Break Locations sheet and are linked using the Break ID.

This sheet is used only when Non-uniform is selected as the Break Method in the Settings sheet.

Break ID

Defines the unique identifier for the break. This value is used to link the break definition in this sheet with the allowable break locations specified in the Non-uniform Break Locations sheet.

Each Break ID must be unique. Or it can be blank. If the Break ID is blank, cuOpt will assume that every site is a possible break location.

Vehicle ID

Specifies the vehicle to which the break applies.

This field must match a Vehicle ID defined in the Vehicles sheet exactly.

A vehicle may appear on multiple rows if it has multiple required breaks.

Break Window Start

Defines the earliest time the break may begin.

This value must be entered as a non-negative number (for example, 0, 8, 480, 12.5). Do not enter clock-formatted times such as 8:00 AM or 14:30. All time values in cuOpt are numeric and represent whatever unit you choose to model (minutes, hours, days, etc.). NVIDIA cuOpt does not interpret calendar time, it only uses numeric values consistently throughout the model.

Break Window End

Defines the latest time by which the break must begin. This value needs to be greater than or equal to the Break Window Start.

This value must be entered as a non-negative number (for example, 0, 8, 480, 12.5). Do not enter clock-formatted times such as 8:00 AM or 14:30. All time values in cuOpt are numeric and represent whatever unit you choose to model (minutes, hours, days, etc.). NVIDIA cuOpt does not interpret calendar time, it only uses numeric values consistently throughout the model.

Break Duration

Defines the length of the break.

This value must be a non-negative number and must use the same time unit as the rest of the model. The solver will schedule a break of this duration within the specified break window.

Rules and Structure

• Break ID must be unique, unless it is blank.

• Vehicle ID must exist in the Vehicles sheet.

• Break Window End must be greater than or equal to Break Window Start.

• Break Duration must be non-negative.

• Each Break ID must have corresponding allowable locations defined in the Non-uniform Break Locations sheet.
