“…The sequence of negotiation processes between the set of ITBAs={ITBA 1 , ITBA 2 , …, ITBA n } and SPAs={SPA 1 , SPA 2 , …, SPA m } can be formulated by the set of offers or counteroffers ρ τ ={ρ τ (1) , ρ τ (2) , ρ τ (3) , ρ τ (4) , …, ρ τ(k-1) , ρ τ(k) } exchanged concerning period τ. Here, the set ρ τ ={ρ τ (1) , ρ τ (3) , …, ρ τ(k-1) } denotes the sequence of offers generated by the ITBAs and the set ρ τ ={ρ τ (2) , ρ τ (4) , …, ρ τ(k) } denotes the sequence of counteroffers received by the ITBAs from the respective SPAs. Each negotiation offer ρ τ (1) is generated by varying the preferences of 'n' number of negotiation attributes ρ x(1) ={ρ x(1)←[0,1] , ρ x(2)←[0,1] , …, ρ x(n)←[0,1] }.…”
