Tāpae pūnaha, ona rerekē me te pūtake pūtaiao

pūnaha te tāpae whakaaro (QS) ko te tikanga i roto i nei i te tikanga o te whakawhanakehia rawa hoki tenei mea matatini, i reira ko te utu o ngā whakaritenga e haere mai ana ki te pūnaha. He āhuatanga matua o tenei pūnaha ko te rahinga o te maha o ngā kaimahi (mahi) pūrere. Ka taea e ngā reira i tetahi ki te mutu-.

I roto i te runga ki taua, i reira ko te pea e kore te ratonga tatari ranei, wehewehe pūnaha:

- WE, te wahi kihai i reira he taputapu kotahi (mea) ki te whakatau i te whakaritenga mā te whakauru i roto i te wa i homai. I roto i tenei take, ngaro te he whakaritenga taua;

- pūnaha tāpae ki tatari, e kei te whakaritenga rokiroki, e te mea e taea ki te tango i katoa o ratou, hanga he rārangi;

- he pūnaha ki te iti kaha o te puku te wahi nga whāititanga me whakatau te uara o te rārangi o ngā whakaritenga ki te kia makona. He e ngaro aua whakaritenga e kore e taea e e uru i roto i te mahara.

hāngai katoa QS whānui o ngā whakaritenga, me ona mahi i runga i te ako ratonga. Ka rite ki te tauira o taua tauira mahi e taea e:

- FCFS / FIFO - he pūnaha i roto i i tutaki te whakaritenga kei te tuatahi i roto i te rārangi tuatahi;

- LCFS / LIFO - QS, te wahi serviced te tuatahi kei roto i te wā whakamutunga o te whakaritenga;

- tauira tupurangi - te pūnaha whakatau i te whakaritenga i runga i te pūtake o te kōwhiringa tupurangi.

Tikanga, He he hanganga rawa matatini te pūnaha taua.

whakaahuatia Tetahi pūnaha tāpae te ki nga ariā me ngā kāwai e whai ake nei:

- whakaritenga - te hanganga whakaaturanga o te tono ratonga me;

- rere taumai - tono katoa ki te whakatau i nga whakaritenga o tomo te pūnaha;

- te wā mahi - te wa e hiahiatia ana ki te whakaoti i tono ratonga riro;

- tauira pāngarau - whakahuatia i roto i te puka pāngarau, ka ki te awhina o te taputapu pāngarau o te tauira QS.

Ka rite ki te āhuatanga matatini o te hanganga, te pūnaha te tāpae ko te kaupapa o te ako pūtaiao o te ariā tūponotanga. Hei wāhanga o tenei wāhi nui o te matauranga pūtaiao, wehea ki te maha ngā ariā, ia o nei ko makona ariā te tāpae motuhake. Ēnei ariā ahu ki te whakamahi i te huarahi o tatauranga pāngarau.

Ko te kaiwhakarewa o tetahi o te tuatahi hou WE he A. Ya. Hinchin, e tāia te ariā o te awa o ngā ōrite. Katahi te operator Danish waea, a i muri - kua whakawhanakehia te pūtaiao Agner Erlang, ona ake ariā (i runga i te tauira o ngā waea, tārewa te tono ki te whakatau i te hononga), kua nei tohaina kē QS ki tumanako, me te kahore tumanako.

Te paturaa i te hangarau te tāpae hou ko te nuinga tikanga whakatauira. He he ano hoki te pūnaha o te rangahau whakahaeretia e te e tikanga tātari, engari ko te tino matatini tenei huarahi. E WE ngā aua pūnaha e taea te ako ki te awhina o tikanga tauanga - whakatauira tauanga me te tātari tauanga.

riro ia pūnaha tāpae he priori e reira te tahi mau rave'a paerewa i roto i nei tono he kaupapa ki te whakatau. Ēnei tono haere i roto i te takere mahi pera-ka karanga, he kanorau i roto i to ratou whakaaro me āhuatanga e. mai tono wa nuinga huru, he rota o ratou, Na, ki te whakatū i hononga arorau, me te causal i waenganui ko ratou tino uaua. mutunga pūtaiao, i runga i tenei kaupapa, ko e te CMO, i roto i to ratou nuinga rawa, mahi i runga i te parau tumu o te randomness.
