A Coordination of Risk Management for Supply Chains Organized as Virtual Enterprises

Algorithm 1

Begin

Let particle 𝐗_temp be a zero matrix, 𝑥_{(temp)𝑙ℎ}=0,  𝑙=1,…, 𝑁,  ℎ=1,…, 𝑊.

For 𝑙 = 1 to 𝑁

 For ℎ = 1 to 𝑊

  𝑠𝑣_𝑡𝑙ℎ=11+exp−𝑣_𝑡𝑙ℎ

 End

 For ℎ = 1 to 𝑊

  𝑝_𝑡𝑠𝑣(𝑙,ℎ)=^𝑡𝑙ℎ∑^𝑊_ℎ𝑠𝑣_𝑡𝑙ℎ

  If  random number  ≤ 𝑝_𝑡(𝑙,ℎ),

  Action ℎ is selected for risk factor 𝑙, 𝑥_{(temp)𝑙ℎ}=1. go to next_risk_factor.

 End

Next_risk_factor

End

𝐗_𝑡=𝐗_temp.
