George,
today some positive impressions...
In the following I'll report about some experiences I gained (for others who want to start playing it, too) and want to address some specific issues, partially being discussed before.
1.First running wood scenario
Wow...! slowly I'm starting to have fun ...even with the wood industry.
I found a workaround of the early closes of wood facilities and played it two times, same starting scenario. In the 1st trial I tried to push it to the limit, in the 2nd trial the goal was to establish a "normal" industry, which works smoothly over the time.
2.Experiences
To start with the wood industry you need to do some "pre-work". "Refined products" (to the paper mill) and dyes (to the printing works) have to be delivered. Best is to do both in advance (!) before you start to build up the wood industry.
These two issues plus the transport FROM the sawmill to the paper mill seem to be critical issues to me to gain a smoothly running wood industry.
a) Forests
I picked up wood from 2 forest areas, but focussed more or less only on one. Regarding area1 (1 forest) the production was relatively stable and the amount of messages was ok. To area2 (3 forest) I had only 2 trains running ... and the forests in that area changed quite often the production output and with it more messages were coming up.
b) Sawmill
If the sawmill has always enough wood and enough trains are picking up the "wood products", its production runs smoothly. Crucial is here to pick up the "wood products" timely that your production of "wood products" gets high/stays high.
c) Paper mill
If sufficient "wood products" and sufficient "refined products" are available, no critical problems are coming up.
Disruptions can esp. happen if you have no "refined products" available. After some time there is no storage capacity for your "wood products" to be delivered and that will harm the transports from your sawmill and at the end your wood production in the forest as well.
- Production last month and production level: see below.
d) Printing Works
If the sufficient amount of dyes and paper is available, it is smoothly running. Crucial here is the availibity of dyes.
- Production last month and production level: see below.
e) Furniture Factory
I lost the factory quite quickly and bought only in the 2nd scenario a new one. One specific event happened as I clicked once on the factory to get its specific information. The game crashed and I received an error message ("§...").
3.Unclear issues
a)
Production changes 
The production rate of forests is still a "volatile" question for me. Is it possible to have smaller degrees of these changes (not 50%, may be only 25%) ?
b)
Production level
- The "production of the last month" for the sawmill, the paper mill and the printing works changed relatively often, despite the fact that the incoming delivery and the transports from each facility was quite stable.
- For the forests and the sawmill I reached the "ultimate production level", but for the "paper mill" and the "printing works" I got always a "low/very low production level" (examples: paper mill production of 540t/m and 82% transported; printing works 638 crates of goods and 76% transported).
4. Summary, answer & proposal
a)
Early shut downs
Early closes of wood facilities: s. former messages.
b)
Protection period 
Quote: "Does it mean, that you suggest 5 years protection for industries, created in the map editor/map generator, and 2 years for industries, created in game?"
Seems to be reasonable.
c)
Different dificulty levels
Quote: "...is it possible to implement a bit switch with whom the protection period/production volatility can be regulated to a certain amount ?
I do not see the benefit in it. Let us better select the optimal values and use them."
During these two plays I focussed only on the wood industry and did the necessary micro management. My feeling as non-TTD-expert still is that it would be better to have different difficulty levels (novice, regular, professional). I just concentrated on the wood industry, but if I want to develop the usual railway grid, do the city management and wanna play even another industry chain ... and pls. have in mind that different people have different experiences/knowledge and therefore different "optimal values".
d)
Summary
After having played it for a very short time it seems a quite well developed industry scheme. I really enjoyed to play with these new facilities and new cargos. Thanks to everybody who is working on all these superb TTD improvements, here esp. to you, Michael B. and all others working on these industrial improvements.
Both of my trials worked quite well with only a few items to be addressed (s.above). In the first scenario I had more than 40 trains running, in the second only round about 15 and some RV to transport dyes to the printing works and goods from the furniture factory.
