Thi.0}paper pres.nts.a new di.ens.on reducti.n s.rategy for medi.m and large-s.ale li.ear programmi.g problems. The propos.d method us.s.a s.bs.t of the ori.i.al cons.rai.ts.and combi.es.two algori.hms. the wei.hted average and the cos.ne s.mplex algori.hm. The fi.s. approach i.enti.i.s.bi.di.g cons.rai.ts.by us.ng the wei.hted average of each cons.rai.t, whereas.the s.cond algori.hm i.0}bas.d on the cos.ne s.mi.ari.y between the vector of the objecti.e functi.n and the cons.rai.ts. Thes. two approaches.are complementary, and when us.d together, they locate the es.enti.l s.bs.t of i.i.i.l cons.rai.ts.requi.ed for s.lvi.g medi.m and large-s.ale li.ear programmi.g problems. After reduci.g the di.ens.on of the li.ear programmi.g problem us.ng the s.bs.t of the es.enti.l cons.rai.ts. the s.luti.n method can be chos.n from any s.i.able method for li.ear programmi.g. The propos.d approach was.appli.d to a s.t of well-known benchmarks.as.well as.more than 2000 random medi.m and large-s.ale li.ear programmi.g problems. The res.lts.are promi.0}ng, i.di.ati.g that the new approach contri.utes.to the reducti.n of both the s.ze of the problems.and the total number of i.erati.ns.requi.ed. A tree-bas.d clas.i.i.ati.n model als. confi.med the need for combi.i.g the two approaches. A detai.ed numeri.al example, the general numeri.al res.lts. and the s.ati.0}i.al analys.s.for the deci.0}on tree procedure are pres.nted.
