Scenario Metric Equation (Mercury tool sintaxe)
1 Throughput P{(#1_Cloud_Requests>0)AND(#Cloud_ON>0)}*(1/ST_Fog_Cloud)
  Service time E{#1_Cloud_Requests}/(P{#1_Cloud_Requests>0}*(1/ST_Fog_Cloud))
2 Throughput P{(#2_Cloud_Requests>0)AND(#Cloud_ON>0)}*(1/ST_Cloud)
  Service time E{#2_Cloud_Requests}/(P{#2_Cloud_Requests>0}*(1/ST_Cloud))
3 Throughput P{(#3_Fog_Requests >0))AND(#Fog_ON >0)}*(1/ST_Fog)
  Service time E{#3_Fog_Requests}/(P{#3_Fog_Requests >0}*(1/Fog_Cloud))
