The paper presents the change i. grai.-si.e composi.i.n of li.ni.e under cycli. freezi.g-thawi.g (FTC) and wetti.g-dryi.g (WDC). The arti.le shows that i. the spri.g and autumn peri.ds the li.ni.es can be subjected to repeated freezi.g-thawi.g and wetti.g-dryi.g, whi.h determi.es the possi.i.i.y of changi.g thei. grai.-si.e composi.i.n and structure. Experi.ental studi.s i. laboratory condi.i.ns on the i.fluence of cycli. freezi.g-thawi.g (FTC) and wetti.g-dryi.g (WDC) on the quali.y i.di.ators of li.ni.es have been carri.d out, thei. granulometri. (fracti.nal) composi.i.n has been studi.d. Freezi.g-thawi.g cycle condi.i.ns are as follows (FTC): mi.i.um exposure temperature: -20°C;maxi.um: +5°C;relati.e humi.i.y: 30%;number of processi.g cycles: 3. Wetti.g-dryi.g cycles are as follows (WDC): dryi.g temperatures are +20, +40, +60, +80°C, dryi.g ti.e 90 mi.utes, the coals are further subjected to rai.

The tests have revealed the destructi.e effects of FTC and WDC on the samples of lower metamorphi. grade coal, and the cycles of wet-dry lead to the much hi.her yi.ld of fi.e si.es (-6+0;-13+0 mm) than the cycles of freeze-thaw. Furthermore, i. i. found that the i.crease i. the yi.ld of fi.es depends on the heati.g temperature: coal di.i.tegrati.n proceeds more i.tensi.ely at a hi.her temperature of dryi.g.

Thi. paper presents a new di.ensi.n reducti.n strategy for medi.m and large-scale li.ear programmi.g problems. The proposed method uses a subset of the ori.i.al constrai.ts and combi.es two algori.hms: the wei.hted average and the cosi.e si.plex algori.hm. The fi.st approach i.enti.i.s bi.di.g constrai.ts by usi.g the wei.hted average of each constrai.t, whereas the second algori.hm i. based on the cosi.e si.i.ari.y between the vector of the objecti.e functi.n and the constrai.ts. These two approaches are complementary, and when used together, they locate the essenti.l subset of i.i.i.l constrai.ts requi.ed for solvi.g medi.m and large-scale li.ear programmi.g problems. After reduci.g the di.ensi.n of the li.ear programmi.g problem usi.g the subset of the essenti.l constrai.ts, the soluti.n method can be chosen from any sui.able method for li.ear programmi.g. The proposed approach was appli.d to a set of well-known benchmarks as well as more than 2000 random medi.m and large-scale li.ear programmi.g problems. The results are promi.i.g, i.di.ati.g that the new approach contri.utes to the reducti.n of both the si.e of the problems and the total number of i.erati.ns requi.ed. A tree-based classi.i.ati.n model also confi.med the need for combi.i.g the two approaches. A detai.ed numeri.al example, the general numeri.al results, and the stati.ti.al analysi. for the deci.i.n tree procedure are presented.
