Abstract: Consider the delay differential equation $$\dot{x}(t)=a\int _0^r x(t-s)\,d\eta (s)-g(x(t))$$x˙(t)=a∫0rx(t-s)dη(s)-g(x(t)) and the neutral type differential equation $${\dot{y}}(t)=a\int _0^r \dot{y}(t-s)\,d\mu (s)-g(y(t))$$y˙(t)=a∫0ry˙(t-s)dμ(s)-g(y(t)) where $$a>0, g:{\mathbb {R}}\rightarrow {\mathbb {R}}$$a>0,g:R→R is smooth, $$ug(u)>0$$ug(u)>0 for $$u\ne 0, \int _0^s g(u)\,du\rightarrow \infty…

Abstract: Abstract Due to heat prosumers' dual roles of heat producer and heat consumer, the future district heating (DH) systems will become more flexible and competitive. However, the current heating price models have not yet supported…
