147 Shift Scheduling u Different priorities for starting a break or an off shift may be defined. Different priorities for while on break or on shift may also be defined. u Logic may be applied to break and offshift periods as well as pre-break and pre-offshift periods.

148 Choose from Define or Assign Choose from Define or Assign

149 Note ability to modify shift Note ability to modify shift

150 Several locations and resources may be assigned to the same shift. Resources within a single group (e.g. 5 repairman) may be assigned to different shifts.

Priorities for ending shift, off shift, starting break and break. Priorities for ending shift, off shift, starting break and break. Logic for pre-off shift, off shift, pre-break and break is entered here. Logic for pre-off shift, off shift, pre-break and break is entered here.

151 Static Resources u Used for immobile resources u Do not require assignment to a path network u Place the graphic directly on the layout where you want the resource u Changes color to show status

152 Static Resources: Select the graphic, click on the add button and click on the layout Static Resources: Select the graphic, click on the add button and click on the layout

153 Routing Path Movement u Entities may be moved on Routing Paths (process arrows) u They may only move for a time expression - use the MOVE FOR statement in Move Logic u Routing paths may be bent by adding joints with a right click

154 Example of a bent routing path. Paths are automatically drawn when the process is defined. Bend them by adding a joint after right clicking on the path. Entities, but not resources, may move on the path Example of a bent routing path. Paths are automatically drawn when the process is defined.

157 Operation Statements u LOAD Both a Routing Rule AND an Operation Statement. As a Routing Rule: holds the entity at current location until another entity at a different location calls for it with a LOAD Operation Statement. As an Operation Statement: loads a specified quantity of entities onto the current entity. Syntax:LOAD

158 Operation Statements u UNLOAD Unloads a certain quantity of entities. If the numeric expression is larger than the number of loaded items, it will unload all items and ignore the difference. Syntax:UNLOAD UNLOAD 5 IFF

After defining the sets of values you wish the RTI Macros to assume, save them as different Scenarios. Then select Simulation - Scenarios and select Run Scenarios.

184 Termination logic executes after the model finishes running. It is most often used to do calculations with variables that you want to represent a numeric value that cannot be calculated until all other values in the model are completed. It is also used to write information to an external file.

185 Operation Statements u GETCOST() Returns the accumulated cost of the entity executing the statement. To record this value for later viewing, place it in a variable. Syntax:vEntity_Cost = GETCOST()
