Optimisation Entities 5.3 Specifying control variables for an optimisation activity The user can specify the name of the Control Variables, Control type (Time-invariant, Piecewise-constant or Piecewise-linear) and Allowable values (Continuous, Binary, Enumerated, Integer or Special Ordered Set 1) in the Control tab (see Figure 5.2). Depending on the Control type selected, the user will have different options for the Allowable values. Details of how to specify these will be presented in the following sections. Selected variable (yellow frame) Time profile shown in the bottom cell matrix Drag to internally resize the workbook Figure 5.2: Control tab of Optimisation Entity 44 Selected in the middle group of radio buttons Button to delete variables 5.3.1 Time-invariant controls The user needs to specify the Initial guess, Lower bound and Upper bound for both the Continuous and Integer control variables, as shown in Figure 5.3 and Figure 5.4.
Figure 5.3: Time-invariant continuous control variables Figure 5.4: Time-invariant integer control variables 45 Specifying control variables for an optimisation activity When Binary Allowable values is selected, the user needs to select an appropriate initial guess for the Time-invariant control variable from the drop-down list, i.e. 0 is False and 1 is True (see Figure 5.5). Click on the arrow to display drop-down list Figure 5.5: Time-invariant binary control variables For Time-invariant Enumerated control variables, the user can enter the possible guesses in the blank field and then use the Add and Delete buttons to compile the list. The initial guess can be selected either by clicking the arrows to scroll to the desired value of the list of possible values or choosing the value directly in the list (see Figure 5.6).
