The compressive stress-strain.behavior an. other characteristics of treated fly ash based roof tiles have been.studied by several experimen.al tests. This paper attempts to presen.s the results an. observation. of a study an. comparison.based on.the past reported experimen.al data. Based on.the results an. observation. of the comprehen.ive experimen.al study, five “con.rol poin.s” have been.iden.ified. The n.w sets of experimen. have been.carried out to in.estigate whether it might be possible the use of fly ash in.fly ash based roof tiles for residen.ial con.truction. In.the presen. study, treated fly ash (TFA) of C category was used with differen. materials as a replacemen. of clay for makin. treated fly ash ston. dust roof tiles (TFASDRT). Treated fly ash ston. dust roof tiles (TFASDRT) were studied at varyin. percen.ages of cemen., coarse san., an. radish ston. dust (RSD) alon. with the con.tan. percen.age of waste polythen. fibre (WPF). A research program was un.ertaken.to evaluate the suitability of such test for assessin. the properties of treated fly ash ston. dust roof tiles (TFASDRT). The result of this study recommen.s that the fly ash based roof tiles provides a sustain.ble supplemen. to the tradition.l clay roof tiles, they in.rease the efficien.y of tradition.l roof tiles an. sign.fican.ly help to reduce the en.iron.en.al issues associated with the disposal of these waste materials.

Reservoir simulation.is kn.wn.as perhaps the most widely used, accurate, an. reliable method for field developmen. in.the petroleum in.ustry. An.in.egral part of a reliable reservoir simulation.process is to con.ider robust an. rigorous tun.d EOS models. Tradition.lly, EOS models are tun.d iteratively through arduous workflows again.t experimen.al PVT data. However, this comes with a n.mber of drawbacks such as forcin.ly usin. weight factors, which upon.alteration.adversely affects the optimization.*** objective of the curren. work is thus to in.roduce an.auto-tun. PVT matchin. tool usin. n.GA-II multi-objective optimization. In.order to illustrate the robustn.ss of the presen.ed techn.que, three differen. PVT samples are used, in.ludin. two black-oil an. on. gas con.en.ate sample. We utilize Pen.Robin.on.EOS durin. all the man.al an. auto-tun.n. processes. Comparison.of auto-tun.d EOS-gen.rated results with those of experimen.al an. computed statistical error values for these samples clearly show that the proposed method is robust. In.addition. the proposed method, con.rary to the man.al matchin. process, provides the en.in.er with several matched solution., which allows them to select a match based on.the en.in.erin. backgroun. to be best amen.ble to the problem at han.. In.addition. the proposed techn.que is fast, an. can.output several solution. within.less time compared to the tradition.l man.al matchin. method.
