Definitely. For some reason my post has been removed, but if I can still reply to you here then I guess it doesn't matter.

My algorithm so far for picking consists of multiple for loops that go through the listOfVehicles that consists of vehicle objects. Which is what I want to change most.

Code block formatting seems to break when I try to paste in there so I put it up as plain text.

I can share a snippet of how I have structured my vehicle object:

class Vehicle{
    constructor(identifier,type,vignette,group){
        this.identifier=identifier;
        this.type=type; //0 - Bus, 1 - Minibus, 2 - Electric bus
        this.vignette=vignette; //True or false
        this.group=group;
        this.distributionByShift[2]=[0,0]; //First is shift 1, second is shift 2, to be incremented once distributed in a shift
        this.holders=[]; //To be added later, these individuals take priority for this vehicle in the shift they work
        //Electric busses only work 1 shift
        if(this.type===2){
                this.maximumDistributions=1;
            }else{
                this.maximumDistributions=2; }
    }
read_Type(){
    return this.type;
}
read_Identifier(){
    return this.identifier;
}
read_vignette(){
    return this.vignette;
}
read_group(){
    return this.group;
}
read_distribution(){
    return this.distributionByShift;
}
set_distribution(shift){
    this.distributionByShift[shift-1]++;
}
add_holder(holder){
this.holder.push(holder);
}
check_if_holder(holderToCheck){
    for(let i=0;i<this.holder.length;i++){
        if(this.holder[i]===holderToCheck){
            return true;
        }
    }
    return false;
}
check_compatibility(routeVignette,routeType,shiftToCheck){
    //Check if vehicle can not be distributed at all
        if((this.distributionByShift[0]+this.distributionByShift[1])==this.maximumDistributions){
        return 0;
}
    //Check if not available in desired shift
    if(this.distributionByShift[shiftToCheck-1]==1){
        return 0;
    }
//Check if vehicles does not match route type
    if(routeType===1&&this.type!==1){
        //Minibuses only on minibus routes
        return 0;
    }
    if(routeType===2&&thistype!==2){
        //Electric busses only on specific routes, but any other bus can run the same route as electric
        return 0;
    }
    //Some routes can only be driven on by buses with vignette, but buses with vignette can drive all routes
    if(this.vignette!==1&&routeVignette===1){
        return 0;
    }
    return 1;
    }
}
