ExP9,12 Holland scenario experiences.

[AvG]

Exp9.12 Adapted Pak-Britain. Bpm=24 Adapted monthly costs.

After 1 game-year I will make an analysis of my Holland 1830 scenario.

Town-growth.
Used the standard-Exp settings of 915/625/375.
Some results:
Amsterdam: 7791 >> 12798 = 164% growth/year
Zaandam: 744 >> 3104  = 417% growth/year
Haarlem: 1442 >> 3892 = 269% growth/year
These growth figures are very unrealistic and not useable for longlasting scenarios.
For a city like Amsterdam it should be 6 perMILLE/year.
In a new start I will try growth-factors of 10000/6000/2000

Town density.
The towns are getting to large.
In the centres there are no 4-5 story buildings.
Towns are growing to much along connection roads. In 1 year Amsterdam and Zaandam,
distance ~10 km, were almost connected by houses.
There are to many roads. Maybe the the stop-coverage increase from 2 to 3 allows
for less streets in a town.
In the next scenario I will try:
renovation_percentage = 38 >> 80
minimum_building_desity = 28 >> 80

Passenger-factor.
Allthough the passengers-factor was reduced from  16 to 8 it was impossible to prevent overcrowding. I used a horsetram-system but even then still problems due to limited capacities and loads.
In the early years most people had no money for traveling.
I can imagine an increasing factor to compensate for this. (f.i. +1%/y)
Next scenario I will use a factor of 4.

Money.
I started with 50K Cr.
In combination with 0,01 Cr revenue for passengers and mail I had after 6 monthes
a monthly profit of ~3K Cr.
Due to the limited starting-money and credit-limit it was going to take to long for expanding the network. The increased prices of track-laying are also of great influence. (1800 Plated Railway cost 1609 Cr/km with monthly maint. of 8,32 Cr/m)
Next scenario starting with 200K Cr.

Industry.
I started with 0 industry.
The settings-menu indicates industry_increase_every 2000
With all that growth I expected the arise of at least 1 industry. Nothing happened.
What can be the cause? (Holland is allmost compltely empty)

AvG,

interesting analysis. Just one or two comments. The town growth seems to work reasonably well in Pak128.Britain-Ex 0.8 with default settings (indeed, if anything, it might be a little slow), so perhaps your 24 bits per month setting has affected it? I have not yet studied fully the relationship between town growth and the bits per month setting.

Secondly, if you want industries to grow in Experimental, don't start with zero industries: the system in Experimental is to fix a "target industry density" when the map is first created based on the number of industries (taking into account their "distributionweight" factor) relative to the size of the population, and then matching as closely as possible the actual industry density as is adjusted every time that an industry is added or removed to that target industry density. Industries will only be added if the actual industry density is lower than the target industry density. If you start with a map with zero industries, the target industry density will be fixed at zero, and no industries will ever be added.

James,
Good to know these background on industry.
I experimented a bit and concluded that you also need at least 1 town to get that one industry.
Just to be  sure: The first and only industry can be a pub that, on itself does NOT give any goods-transport possibilities. Right?

AvG,

generally, a chain would be built such that consumers are connected to producers: I do not think that a lone industry will spawn (and the option at map generation is as to the number of chains, not the number of industries, created). If you end up with too few industries at the beginning, then the overall density of industries will remain the same throughout the game, for the reason described above, and you might find yourself with very few industries for the whole game. Simutrans-Experimental is not designed to give rise to a large number of industries growing from nothing: it is designed to preserve stasis in the overall density of industries, as this is more realistic.

I ordered the Publicplayer to build a grain-bakery chain to see what would happen.
Already some time ago I did not like the unrealistic huge production and consumption levels. Based on that I created early farms, greenfields etc adapted for situations that were more likely existing in 1800.
Also in this area the bpm-setting of 24 is ruiining the scenario.
A small one family-farm can feed a whole city or even a country.

I am not sure that I follow as to the relevance of the 24bpm setting here?

[AvG]

Also in the production area the bpm-setting has a tremendous effect on the monthly output of industries.
In fact so much that I probablycan't correct it.
AvG

[jamespetts]

It has an effect on the "monthly" output only in so far as it makes a "month" show as taking far more game time than a lower setting: the production per stable unit of game time remains the same.
