Zakaj dva načrtovalca dajeta različne odgovore za avto

Enak avto, enaka pot, enak dan. Eden pravi tri postanke in šest ur, drugi pravi dva postanka in pet. Nobeden ne laže — razlikujeta se v stvareh, ki so resnično negotove.

Predpostavljajo različne hitrosti

Aerodinamični upor narašča s kvadratom hitrosti, moč, potrebna za njegovo premagovanje, pa s kubom. Razlika med 110 km/h in 130 km/h torej ni dvajsetodstotna razlika v porabi; je precej večja. Načrtovalec, ki predpostavlja, da boste vozili pri omejitvi, in tisti, ki predpostavlja, da boste vozili pod njo, modelirata dve različni poti.

Večina orodij vam omogoča, da to nastavite, in večina ljudi tega nikoli ne stori. Če se dva načrtovalca razlikujeta in lahko preverite le eno stvar, preverite predpostavljeno hitrost.

Različne so tudi njihove predpostavke o krivulji polnjenja, ali pa je sploh ne modelirajo

Litij-ionska baterija sprejema visoko moč pri nizkem stanju napolnjenosti in se strmo upočasni, ko se napolni [3]. Praktična posledica je, da zadnjih dvajset odstotkov polnjenja lahko traja toliko časa kot prvih petdeset, zato je optimalna strategija običajno več postankov, vsak krajši, namesto manj in daljših.

Načrtovalec, ki to pravilno modelira, bo ustvaril načrt, ki izgleda neučinkovito — štiri postanke namesto dveh — in vas kljub temu pripeljal tja prej. Načrtovalec, ki obravnava polnjenje kot enotno ceno, ustvari urejen načrt, ki pa je napačen.

Razlikujejo se glede vremena

Mraz zmanjšuje uporabni doseg in hkrati upočasnjuje hitrost, s katero baterija sprejema polnjenje [4]. Obe učinki delujeta v isto smer, načrt, ki temelji na porabi v blagih vremenskih razmerah, pa lahko propade na način, ki ga majhna napaka ne pokriva.

To je vrstica, kjer je razlika med načrtovalci najbolj pomembna, in zato tabela zmožnosti obravnava modeliranje vremena kot prvo razredno funkcijo, ne pa le prijaznost.

Razlikujejo se glede tega, koliko strahu bi morali imeti

Rezerva ob prihodu — koliko napolnjenosti načrtovalec vztraja, da imate ob prihodu na postanek — ni fizična količina. To je politika. Orodje, ki je nastavljeno na prihod pri 10 %, in tisto, ki je nastavljeno na prihod pri 20 %, bosta ustvarila materialno različna potovanja iz identičnih vhodov, in nobeno od njiju ni napačno.

Anksioznost glede dosega je dobro dokumentiran vpliv na to, kako se vozniki dejansko obnašajo, ločeno od tega, kaj avto lahko stori [5]. Načrtovalec, ki vam omogoča, da to nastavite, vam omogoča, da cenite svoje živce, kar je pravo mesto za to odločitev.

Kaj storiti glede tega

  • Nastavite predpostavko hitrosti na to, kar dejansko vozite, ne na to, kar nameravate.
  • Na hladnem dnevu načrtujte z pesimističnim orodjem in optimistično obravnavajte kot najboljši primer.
  • Zaupajte načrtovalcu, ki vam daje več, krajši postankov, pred tistim, ki vam daje manj, daljših.
  • Načrtujte ponovno sredi poti, ne na začetku. Vsak vhod se je do takrat spremenil.
