Abstract [en]

The purpose of this essay is to investigate if it is eective to switch strategies

for elevators during one day in an oce building. This essay describes some

of the strategies in use today, followed by a comparison and analysis of two

of the strategies described. We have also implemented optimizations to one

of these strategies. From our test results we can conclude that our optimized

strategy worked and produced better results on average waiting time and

total traveling time than the two strategies we previously implemented and

that it is not necessarily eective to completely change strategies but change

parts of them depending on the trac ow.

Abstract [sv]

Syftet med denna rapport ar att undersoka om det ar eektivt att byta

strategi for hissar i en kontorsbyggnad under en dags olika trakoden. Forst

beskrivs nagra av de vanligaste strategierna, vilket foljs av en jamforelse

och analys av tva av dessa. For att kunna jamfora dessa strategier har en

implementation av ett program som simulerar en byggnad med hissar gjorts.

I programmet anvands sedan dessa strategier for att ta fram testresultat. Den

mest eektiva av dessa tva strategier har optimerats och jamforts ytterligare

med de tidigare resultaten. Testresultaten visar att den optimerade strategin

var den mest eektiva med avseende pa genomsnittsvantetiden och den totala

genomsnittsrestiden, och att det inte ar nodvandigt att helt byta strategi

under dagen, men att det lonar sig att optimera delar av den, beroende pa
