General

The general tab provides an overview of the simulated model.

• Output From: Data file location.
• Date: Simulation date.
• Time: Simulation time.
• Total Cost: Total cost for the entire model run.
• Scenario: Type of simulation.
• Replication: Replication type.
• Simulation Time: Total time the simulation ran for.

Entity

Click on the Entity tab while on the Standard Report.

• Entity Name: Names of all the entities that have been added to the model with statistics enabled.
• Qty Processed: The total number of entities processed through the model. Only exiting entities count in Qty Processed.
• Average Cycle Time: The average time each entity spent in the model.

  Cycle Time is the total elapsed time to move a unit of work from the beginning to the end of a process. Cycle time includes process time, during which a unit is acted upon to bring it closer to an output, and delay time, during which a unit of work is spent waiting to take the next action.

• Average VA Time: Average value-added time each entity spent being processed in activities or moved from one activity or storage to the next, does not include the time waiting or time at any activity that is declared as NVA (Non-Value Added).

  Activity time begins as soon as an entity enters the capacity of the activity, and ends when the entity leaves the capacity, either by moving to the output queue or to the next location in the model. Value-added time is accrued only from a TIME statement in the action logic or from the General tab’s Time field.

• Average RNVA Time: Average time each entity spent being in activities set to RNVA. RNVA activities include actions that are required but do not add value (as defined by the customer). An example of a RNVA activity might include a governmental inspection that neither the producer nor the customer identifies as value-adding.
• Average NVA Time: Average Non-value-added time each entity spent at an activity declared as NVA, the time an entity spends being idle, waiting for a resource, in storage, traveling on a route, waiting in an input queue or when a Wait Until statement holds it.
• Average Touch Time Cost: The average cost of the entity. This is based on how much work was done on the entity by activities, resources etc that have an associated cost. Unused resource cost is not applied to the average cost, to see cost with unused resource cost added, see the Average Total Cost.
• Average Total Cost: The total cost for each entity. Total Cost represents the sum of all the costs to run the process plus the addition of all unused resource costs. Includes sum of;
  Used / Unused Resource cost.
  1. VA, NVA, and BVA costs for each entity.
  2. Initial entity cost.
  3. Entity waiting cost.

  Only entities that exit the model have statistics collected for them and reported. If an entity is renamed at some point in the model, the original entity will not report statistics. Only the new name will show stats. Another instance when the entity summary will show 0’s is when one entity is attached to another without detaching them before they exit the model.

• Process Efficiency: Average VA Time / Average Throughput Time
• Weighted Overall Process Efficiency: Becomes accessible when two or more part or entity types exit the model. The weighting factor is the quantity of entities exiting the system. Entities having more exits provide a higher contribution to the weighted efficiency. The formula follows (Process Efficiency Entity 1 * Qty Processed Entity 1) + (Process Efficiency Entity 2 * Qty Processed Entity 2) + (Process Efficiency Entity x * Qty Processed Entity x) / (Qty Processed Entity 1 + Qty Processed Entity 2 + Qty Processed Entity x).

Activities

 

• Activity Name: Names of all the activities that have been added to the model with statistics enabled.
• Scheduled Hours: The total number of hours the activity was scheduled to be available, as the result of any shift file it uses, defined in the properties dialog.
• Capacity: Capacity of the activity, defined in the properties dialog.
• Total Entries: The total number of entities that entered the activity, not including entities arriving to be attached. Entities arriving that have been previously grouped or have entities attached to them to form a single entity only count as one entry.
• Average (Sec/Min/Hrs/Days) Per Entry: Average time an entity spent at the activity, time value is based on what is selected in the Simulation \ Options window. This time may include partial times from the beginning and end of the actual run time.
• Average Contents: Average entities in the activity at the same time.
• Maximum Contents: The maximum number of entities that occupied the activity at the same time, over the course of the simulation.
• Current Contents: The number of entities remaining at the activity when the simulation ended.
• % Utilization: The percentage of capacity occupied, on average, during the simulation.

Activity by % (Multi Cap)

 

• Activity Name: Names of all the activities that have been added to the model with statistics enabled and have a capacity of more than 1.
• Scheduled Hours: Scheduled hours for the activity, defined in the properties dialog.
• % Empty: Percentage time the activity was empty.
• % Partially Occupied: The percentage of time the activity had entities but was not filled to capacity. (100% of time – %Full – %Empty)
• % Full: The percentage of time the activity was filled to capacity with entities.

Activity by % (Single Cap)

• Activity Name: Names of all the activities that have been added to the model with statistics enabled and have a capacity of 1.
• Scheduled Hours: Scheduled hours for the activity, defined in the properties dialog.
• % Operation: The percentage of time the activity was actually processing an entity.
• % Idle: The percentage of time that no entities were at the activity, but the activity was not down.
• % Waiting: The percentage of time the activity was waiting for a resource or another entity in order to begin processing or move to the next activity. Any delays in processing routing Action logic are counted as waiting time.
• % Blocked: The percentage of time entities spent waiting for a freed destination. “Blocked” means that an entity cannot move downstream in the model due to insufficient capacity at the next location. The entity has to sit at the current location after the normal processing time is complete until there is room available for it to move.

Resources

 

• Resource Name: Names of all the resources that have been added to the model.
• Units: Number of resources assigned, defined in the properties dialog.
• Scheduled Hours: The total number of hours the resource was scheduled to be available, as determined by the assigned shift file, defined in the properties dialog.
• Number of Times Used: The total number of times the resource has been acquired to transport or process an entity.
• Average (Sec/Min/Hrs/Days) Per Usage: The average time the resource is used by an entity. Time value is based on what is selected in the Simulation \ Options window.
• % Util: The percentage of time the resource spent moving or processing an entity. (100 * (Number of Time Used * Average Minutes Per Usage)) / (Scheduled Hours * 60 min/hr)
• Cost of Used: The total cost of used resources. If the resource is on break, no cost is charged.
• Cost of Unused: Total cost of unused resources. Represents the time you must pay for, even though the resource may not be actively working on entities. The column helps you quantify the resource waste in your process. Unused costs are not included in the report which uses ABC costing.

 Resources are reported both by unit and collectively. The collective unit (aggregate) report for a resource totals the first three fields and averages the last two fields discussed above.

• Scheduled Hours: Total scheduled hours for the resource during simulation, defined in the properties dialog.
• % in Use: The percentage of time the resource was being used by entities.
• % Idle: The percentage of time the resource was available but not in use.
• % Down: The percentage of time the resource was unavailable due to shifts or options selected in the Availability tab for the resource.

Variables

• Variable Name: Names of all the variables that have been added to the model with statistics enabled.
• Total Changes: The total number of times that the value of the given variable changed during the simulation.
