Design Base Isikhathi, Impilo Yesevisi Yokuqamba, Isikhathi Sokubuya - Ingabe Uyahlukanisa Ngokucacile?

I-Design Base Isikhathi, Impilo ye-Design Service, kanye nesikhathi sokubuya yimibono emithathu yesikhathi esiningi esihlangana ngaso onjiniyela abahlelekile. Yize indinganiso ehlanganisiwe yokwakhiwa kwezinhlaka zobunjiniyela
"Izindinganiso" (Kubhekiselwa kuzo "Izindinganiso") Isahluko 2 "Imigomo" ibala izincazelo zesikhathi sesethenjwa sedizayini kanye nempilo yenkonzo yokuqamba, kepha kulinganiselwa ukuthi abantu abaningi basadidekile kancane.

1. Isikhathi sokubuya
Ngaphambi kokuthi singene engxoxweni, ake sibukeze "isikhathi sokubuya." Esihlokweni sethu esedlule, kanye eminyakeni engama-50 = kanye kanye eminyakeni engama-50? - Kushiwo ngomqondo wesine ojwayelekile wesivinini somoya onjiniyela okufanele bazi, isikhathi sokubuya somthwalo sibhekisela ku- "Isilinganiso sesikhathi esiphakathi nendawo esivela phakathi kwesehlakalo", kanye nenkathi yokubuya "okulinganiswayo ngokwedlulele kwe-Lost Amathuba okulingana ngokweqile. Isibonelo, ukuthola imithwalo yomoya nesikhathi sokubuya esiyiminyaka engama-50, amathuba okuba minyaka yonke angama-2%; Ukuze uthole imithwalo yomoya nesikhathi sokubuya seminyaka eyi-100, kungenzeka ukuthi kungenzeka ukuthi kungenzeka kube ngu-1%.

Ngomthwalo womoya ongeyena mnuko odlula unyaka wonke ngu-P, amathuba okungeqisi ijubane lomoya ngonyaka owodwa ngu-1-p, futhi amathuba okungeqisi ngejubane lomoya eminyakeni eyi-1-P) emandleni e-NT. Ngakho-ke, amathuba edlula isivinini somoya eminyakeni yobudala engabalwa ngefomula elandelayo:

Ngokusho kwaleli formula: Ngomthwalo womoya esikhathini sokubuya seminyaka engama-50, ukukhulisa okwedlulele ngu-P = 2%, futhi kungenzeka ukuthi kungenzeka kube yiminyaka engama-50:

Ukudlula kweminyaka eyi-100 kukhuphuka ku:

Futhi amathuba okudlula eminyakeni engama-200 azofinyelela:

2. Design Base Isikhathi
Kusukela esibonelweni esingenhla, singathola lokho ngokulayisha okuguquguqukayo, akunangqondo ukuthi kukhulume kuphela amathuba amaningi ngaphandle kokusho ubude obuhambisanayo. Ngemuva kwakho konke, abantu bazokufa ngokuhamba kwesikhathi, kungenzeka ukuthi amathuba amaningi ahlukahlukene asondele ku-100%, futhi izakhiwo zizowa (ngaphandle kokuthi zidilizwa ngaphambi kokuwa ngaphambi kokuwa). Ngakho-ke, ukuhlanganisa indinganiso yokulinganisa, kuyadingeka ukucacisa isilinganiso sesikhathi esinobunye njengepharamitha yesikhathi yamanani womthwalo oguquguqukayo. Lesi sikhathi sesilinganiso yi- "design reference inkathi".

Isigaba 3.1.3 se-"yekhodi yokulayisha izakhiwo zokwakha" sichaza ukuthi "isikhathi sesethenjwa seminyaka engama-50 sizokwamukelwa lapho kunqunywa inani elimele le imithwalo eguquguqukayo." Lokhu kuhlinzekwa okuphoqelekile. Isizathu esenza ukuthi siphoqelekile ukuthi "akukho mthetho, akukho mbumba we-Square", ngaphandle kokubeka isikhathi, akunangqondo ukuxoxa ngamathuba okudlula umthwalo wezekele kanye nenkomba yokwethembeka (kungenzeka kokwehluleka) kwesakhiwo.
