Edited by: anatolix on 12/12/2009 05:35:09 Hello.
Since Burchov no longer updating Eve Invention Calculator, I created a quick fix for it, so now it should be able to calculate ship research correctly.
Actually I just created fast ugly patch, i.e. I don't generated new shiny databases from scratch, but just replace components numbers in current one. So it still will not be able to calculate small and medium rigs.
Other changes: 1) Several small bug fixed 2) Added several brand-new bugs(I program delphi last time ~10 year ago, so I almost sure - there are new bugs) 3) Invention Calculator now able to calculate profit per day(You all know Scorch L has 500% profitability, but time of construction spoils everything) 4) Database are now in text tab separated format, so you can change it even with excel if you want

Edited by: FroschForscher on 12/12/2009 07:57:49 awesome. could you add a column "revenue per day" to make the list sortable based on it?

Sure. Already done once actually, but lost this source code due to accident. Will do again shortly.
Originally by: FroschForscher how is the revenue per day calculated?
For example look for Inventing the Golem. Invention profit is 35M. Golem build time is 1d 12h, but actually you should build components first. Building components require 8 weeks 6 days! (if you will build them in one job, one after another).
So just divide 35M for 8 weeks 6 days and you receives the profit per day from one slot, which is shown. It is only 1.4M per day.
You should multiply it to number of job you can make simultaneously, i.e. if you can build with 5 slots you profit will be 7M/day, with ten slots 14M/day.

so the revenue per day is based on a already owned bpc? that would explain why you can get green numbers with the revenue per day but red ones in the invention profit at the same time.
for me it would be better if the whole invention/production process is taken into account. but i can live with it like it is

"Error reading NewItems.dat: invalid version information." ?
Strange. Looks like in this case program was able to open NewItems.dat, but was unable to read bytes from it. Like file was zero size. Please try to unpack new program into separate directory, not to previous version directory and try again. If it will not help please post exact message here.
It it really says about UserItems.dat not NewItems.dat just ignore this message. It is shown always on first run, and mean program cannot load user setting(because where is no one yet). It will be shown only on first run.

This is not a sensible approach to take - a significant part of the profit in that scenario is coming from building the components. If you want to look at how much of the profit is coming from building the Golem, not the components, you should use (sale price of Golem - sale price of components) / build time of Golem. This correctly takes into account the opportunity cost of turning the components into a Golem (as opposed to selling them directly without using them to build anything).
By all means let people look at the profitability of building components, too, but keep it separate from the final T2 products. This is just as bad as the 'minerals I mine myself are free' fallacy. --- 34.4:1 mineral compression |

This is interesting theoretical approach - but in practice you cannot build Golem from purchased components, at least with profit. All you can calculate total profitability right now, just set manufatcured=no for components and see overall profit is below zero, so profit per day is looks like useless.

However, this means that the profit from inventing Golems is non-existant. You could gain more profit from building components and selling them on the market, which is a different activity. The program should focus on the value-added by invention itself.

In theory that is true. In practice I don't really monitoring the market, but looks like there is just no market of components. I.e. you could make components which are very cheap realtive to market, but you cannot sell them, cause no one buys them.

I have an Idea - it's just because of decmal separator. I changed file format to text, so 0.95 and 0,95 there are different formats. Try to change decimal separator to "." in you operating system may be it will be ok. I will try to reproduce it and fix...

If you set manufactured=no for a component, does the profit/hr figure count the build time for that component? Does it use the market price for that component, or does it use the cost of the materials needed to build the component?
If invention without building your own components adds no value to the materials that make a Golem, that is what this tool should tell you. I don't wan't to know about items that are only profitable if I spend ages building my own components. I only want to do invention when it's the most profitable step in the supply chain. If building T2 components is more profitable, why should anyone bother with invention?

There is a huge market for non-capital T2 components. It is possible to buy and sell them in enormous volumes at trade hubs. How can you possibly make these claims? --- 34.4:1 mineral compression |

Are you sure it is enormous? Average market of fernite composite armor plates in jita less than 100k/day last half year(now there is exception because of dominion patch - prices are unstable so its about 200K-300K). This amount allow construct only 25 vagabond per day. But market of vagabond is approximately 40 per day in jita. And there is other ships except vagabonds exist too. So i think less then 5% of all ships are produced from purchased components.
If you try to buy components instanly(not by buy orders) you actually cannot constuct any ships with profit to you. So i thing most of market exists due to some emergency need(for example if you miscalc components and create less components 5% than you need it is easer to buy them instead of waiting several days)

May be, but I don't know when exactly. I need a lots of free time for that. Sources from Burchov does't contains SQL queries for creating databases, and anyway database structure changed for Dominion. So I have to completely rewrite import, instead of just patching few numbers.

manufactured=no will use market price. It was so long before my patch.
Please can you fix it so that if you set 'manufactured = no', the build time for those components is not included in the profit/hr figure?

Average market of fernite composite armor plates in jita less than 100k/day last half year(now there is exception because of dominion patch - prices are unstable so its about 200K-300K).

And there is other ships except vagabonds exist too. So i think less then 5% of all ships are produced from purchased components.
You have chosen the most extreme possible example - the build requirements for ships were changed in Dominion so that far more racial armour plates are needed, and far less of all the other T2 components. The markets have not yet settled down - I expect that the volume of plates traded is set to rise significantly in the long term.
Also, ships are not the only T2 items - for people building T2 modules, fewer T2 components are needed, and most of the production costs are from invention. Because the T2 components make up such a small part of the overall costs, it is more affordable to buy them on the market. --- 34.4:1 mineral compression |

There's an error in the items db still -- T2 ship costs are inflated by about 30%, because the number of sylramic fibers required for all T2 armor plate components was decreased from 30 to 10 in Dominion but the database doesn't reflect this. I tried editing the text file but it had no effect.

First off, great job! I love the changes.
Originally by: anatolix 4) Grid now shows invention profit with best decryptor available, not the profit without decryptor.
A few items insist on showing the profit (or loss in many cases) with a decryptor, when no decryptor is the best option. I've noticed this with Drones and frigates.

First, great work but i thinking there is also a error when calculating the production cost for a T2 Ship.
eg. Paladin, 1-Run -4 ME need 225 Antimatter Reactor Units.
According to the prog, -4 ME need 281 Antimatter Reactor Units. Same for rest...
mistake or feature?! :D

Feature requests:
1. For the 'invention profit' column, the profit shown is currently calculated using the decryptor that maximises profit per invention cycle. Please add an option to use the decryptor that maximises profit per day instead, as the two can be different (e.g. Providence -> Ark, best profit/job gives only half the profit/day of the best profit/day).
2. Please remove component/T1 item build time from the profit per day calculation where Manufactured = no is set via the items screen.
3. Please add an option to include copy time for creating T1 BPCs in the profit per hour calculation, for people who depend on their own BPCs.

I will make separate column soon. btw there is a bug in time calculation, I forget to change component building time, so component build for golem for example should be only 2w, not 6w. I will fix this today evening.

Yes, it have a sence.

Don't really understood yet how to make this correctly. There is no meaning to add it to manufacturing time, because blueprint copying uses lab slots, not factory slots. So they not directly affect you manufactoring throughput. May be I should add them to Invention time instead and make a "profit per invention day".

I forgot to add one last feature request - a big one, but potentially really useful: import meta 1-4 item prices (and show which ones are the most profitable to use).
Regarding copy time: it's a separate stage of the process for people who don't buy BPCs, so it should just work like this:
profit per hour = (income - costs)/(total build time + copy time + invention time)
If you want to buy BPCs, you can add their cost via the existing meta item cost field. If you make your own, the time to do so should be added on the bottom half of the equation along with the build & invention time. The idea is to let people see whether there is better profit/hr from buying BPCs or from making their own.
This can be quite significant - e.g. for cloaks, it takes a week to make a max run T1 BPC, comparable to the length of time needed to build the T2 cloaks. Freighters are even worse (I miss the old 0-run BPC exploit ). --- 34.4:1 mineral compression |

Originally by: Kazuo Ishiguro

this only applies for the first process because you wont have a copy to begin with. after that you will copy while you invent and built.
so i¦d say divide by...
...copy time (if copy time is higher than (invention time + built time (all runs of the bpc)) ...built time (all runs) (if built time is higher than copy time + invention time)
i think its always the built time thats highest. so you can copy and invent the next bpc while you built from the last one

Invention and copy jobs are both affected by the limit on concurrent research jobs per character, so if you want to invent at full capacity, you have to do copying in advance. Even if you have the capacity to do it in parallel, it's still x slot-hours of work that has to be done, so it should count towards a 'profit per slot-hour' figure.
It would be far simpler just to leave this as a 'profit per slot-hour' figure, adding together time needed on all the different types of slots, rather than a 'profit per hour via critical path' estimate, which would have to take into account a lot of complex scenarios. It's still a (very useful) benchmark. --- 34.4:1 mineral compression |

i agree with you that the additive approach is far simpler.
however, the inventor has to do network planning and critical path analysis to maximize his profit (and for the perfect pos setup in the first place).
the question is, would an item that is the most profitable based on the simple approach still be the best item after a critical path analysis? if both profit lists (simple/critical path) for all items give (almost) the same result then i¦d say lets keep it simple.
if the lists show huge differences then i¦d say lets follow the critical path or skip the profit per... aproach completely

Originally by: R'SMP I think the original version is missing Salvager II, Codebreaker II and Analyzer II - can you add those?
And also small and medium sized rigs. Yes but not tomorrow. I already said this above - it will require a lot of time to make import from dominion from scratsh. So I will do this as soon as I will have waste of free time :)

I am receiving a bug where by the max size the window can increased is not big enough to contain all the text.
For example in the items edit Items window anything to the right of the import prices from EVE central check box is cut off and the window cannot be resized past this point (horizontally). A similar problem occurs where half of the invention profits box is cut off (vertically).
I can run version 0.45 without these problems
I hope I have explained the problem clearly. I am using Windows 7 with 2560x1600 res.
Can the limit on the size windows can be extended to be removed? or something similar to fix this problem. The program is unusable for me in the current form  |

Assome job continuing the good deed.
I still get a problem on startup though. It reads "Error reading NewItems.dat: invalid item". And then there are no Items in the Main Window list too select for invention jobs.
I am running Visa 64 on german settings. Tried changing the seperator etc. didnt work. Deleted the old folder etc.
A slightly confused looking computer boon here ^^

This is really awesome, mad props for fixing it! I've been addicted to the old edition, it simply is the best invention calculator in my book.

This is a great tool and I really appreciate you updating it for Dominion.
I do have a few feature requests perhaps if you are able:
1. Add more items to the columns selection on the main screen, mainly Single run copy time, Max run copy time, Invention installation, Build installation, and Revenue for this item. I'd really like to see these in the table format because it would be a lot easier to then compare items and see really which is the best for me to manufacture. I realize that since there are sometimes multiple T2 items for each T1 item, that this might be easier said than done, but some ability to see all the data at once would be really nice so that it is easier to compare profit. Perhaps if adding more column items is hard, could there just be an export all pricing data feature where it puts everything currently listed in the main window into a single file with one row per T2 item, so multiple rows of the same T1 item?
2. Currently I can simply use Snagit to capture the text from the main table and move it into excel and then sort it how I like, but a .txt output of the table as tab delimited would be awesome as well.
3. Add some extra keyboard shortcuts for things like "Extra > Invention Results > Add Invention Result, Extra > Shopping List > Add T2 item to list, and Extra > Shopping List > Add invention to list"
4. The original version of this software ran in one single program on the taskbar, but now it seems to have multiple windows listed on the task bar, starting with the main window and then what seems like a blank cmd window that has to remain open, along with new windows for each of the things like invention results, items, etc. Perhaps this is by design to be able to move between open windows more easily, but it just seems to clutter up the task bar quickly.
Thanks, ShaddowTerkker

Thanks for the hard work. Just a few small concerns. I compared all the source code with the originals files and the source changes looks good. Exactly what you would expect however,
As I couldn't find a free dephi compiler that worked out the box I uploaded your exe to www.virscan.org to which scans using 30 different virus scanners. Unfortanately it returned a couple of positive Trojan results. http://www.virscan.org/report/0083b6414735faa4d8b7629d890f1345.html
For comparision the old previous invention calculator recieved no positives. http://www.virscan.org/report/0b2e197ef83a3ab6886a13a344559172.html
The orginal exe was also 1.6 mb where your program is over 7 mb. Thats probably just a compiler setting.

Barakkus - if you're volunteering, the feature requests mentioned earlier in the thread are probably worthy of your attention.

I think it is just virus scan bug. Many trojans written in dephi, my Antivirus(NOD32) says nothing. Size is increased because of debug version.

And btw, in my version of Delphi TTabSheet don't have ExplicitLeft property, while burchov dfm contains it. I thing it is cause issue with form sizes reported here. Does this property introduced in some Update pack? Look like I have same Delphi version as Burchov?

The T2 materials for T2 ships seem to be wrong on the shopping list. If you set any ME with decryptors, and add them to the shopping list, the amount displayed for manufacturing of some components are wrong. They are correct, if you click the build cost on the main screen, but seem to be wrong when adding to the shoppinglist.
Otherwise great job!

Don't know if this is a bug or because it's Windows 7 64Bit. But the Meta levels do not update the chance of success.
Also Deep Core Mining Laser I doesn't have an invention type e.g. Ship, Rig, Normal, it's N/A :)
This is with the 0.49D (Dominion Fix) version.

profit per hour = (income - costs)/(total build time + copy time + invention time)
this only applies for the first process because you wont have a copy to begin with. after that you will copy while you invent and built.
Invention and copy jobs are both affected by the limit on concurrent research jobs per character, so if you want to invent at full capacity, you have to do copying in advance. Even if you have the capacity to do it in parallel, it's still x slot-hours of work that has to be done, so it should count towards a 'profit per slot-hour' figure.
It would be far simpler just to leave this as a 'profit per slot-hour' figure, adding together time needed on all the different types of slots, rather than a 'profit per hour via critical path' estimate, which would have to take into account a lot of complex scenarios. It's still a (very useful) benchmark.
i agree with you that the additive approach is far simpler.
however, the inventor has to do network planning and critical path analysis to maximize his profit (and for the perfect pos setup in the first place).
the question is, would an item that is the most profitable based on the simple approach still be the best item after a critical path analysis? if both profit lists (simple/critical path) for all items give (almost) the same result then i¦d say lets keep it simple.
if the lists show huge differences then i¦d say lets follow the critical path or skip the profit per... aproach completely
Either way, for each individual JOB it requires a copy time at the number of runs, and if successful requires the amount of manufacture time of a SINGLE RUN.
Technically the "time" sunk into profit for a simple T2 invented item is as followed.
Manufacture time + Invention time + (Copy time / T2 BPC Runs)
For example (Using the 0.49D version) a Hulk would be this. 6H 28M (A single copy) + 6H 28M (Invention time) + 2D 15H 20M (Manufacture time)
However, a Mod would be (100MN MWD) You get 1 T2 Run per 30 Run copy of the T1 BPO. So time is.. 1M 18S * 30 (30 run copy) + 6H 28M (Invention Time) + 21H 6M 40S (Manufacture time)

Just FYI, the patch & app works perfectly under linux + wine.
I don't know if there is some bug in the calculations (I'm still trying to figure what does all the shiny numbers exactly means, as I'm not english, I guess it will a pain in the ass to read the entire original thread), but there isn't any obvious bug (except for the help window, who just refuse to show).
Anyway, when I'll be rich, I'll send you some ISK for this great work (SoonÖ ?)

Manufacture time + Invention time + (Copy time / T2 BPC Runs)
One invention attempt can generate a BPC with multiple T2 runs, so your brackets are misplaced. If you also allow for failed attempts, it becomes:
Slot time per T2 run = T1 Build time + T2 build time + (Invention time + copy time)/(T2 runs * success chance)
Remove T1 build time and copy time if you don't do those yourself. --- 34.4:1 mineral compression |

Unfortunately, if you use any kind of font DPI scaling on your computer the patch renders invenction calculator unusable because the words run off the window, and the program appearently has a hard coded resize limit, which forbids you to make the windows bigger to compensate :(. Would sure love it if this was fixed.

hah I guess I didn't check that before posting, because in the examples I included invention time before dividing by T2 runs produced.
I don't like including Invention time with copy time. My own personal Invention sheet for my stuff I have it calculate out in two separate fields. Just in case down the road CCP Change invention time to be proportional to the number of runs the BPC has. I don't think it'll happen but I wanted it separate.
I don't include success chance at this level. It is actually later I calculate actual success rate. The above is time for each successful invention this is part of the reason I also separate them out a lot. I capture the unsuccessful time as well.
The final formula looks like this...
((((Total Successful jobs Copy time / number of T2 runs produced)+(Total Successful jobs Invention time / number of T2 runs produced))+(Total Unsuccessful attempts copy time + Total Unsuccessful attempts Invention time))/Number of science slots used)+((Total T1 Unit Manufacture time + Total T2 Unit Manufacture time)/Number of Manufacturing slots used) = Time Sink per T2 unit Manufactured.
While the formula is not a sign of Mathematical perfection, it's deliberate in case down the road something changes in the process of invention it's easy to change and separate. I actually have each stage in it's own cell with it's containing formula for easier editing when the time comes. LOL It's easier to see on an Excel sheet, Basically the idea is pretty simple, each stage has it's own Time sink. Make sure you capture state of job. I used the idea of "Man hours" Total Man hours sunk into the project then divided it up by number of "slots" or (men) working on it.
This is actually because of multiple toons working on copying, Inventing and manufacturing but working together. It really helps breaking it down like this if you have multiple people working on a simple project. I know there is easier ways of doing it but I wanted to maintain full control and capture time separate for each section.

It would not make much sense to attempt to implement such a labour-intensive approach in a tool designed to produce hundreds of different estimates at once, I'm sure you'd agree. The simpler expression I proposed would be more suitable.
It would also accommodate your own method. If for some reason you prefer not to trust the well-known invention formula for working out long-term profitability (the main use of the invention calculator), you could use your own formula, derived from your records, in place of the one entered in the invention calculator by default. The formula having remained unchanged and the markets fairly well settled for over 2 years, I would consider this rather paranoid.

Hi,
I must say what a fantastic tool this is. I am about to start my invention career, and if I had not found this tool I would have lost hundreds of millions.
One question, with some items you get 5 T2 runs for a 1000 run copy. But If I use a 20 run copy I get 4 T2 runs. Is this really correct? If so it is obviously worth doing a 20 run copy, and saving precious copy slot time in the lab.

I find this program very useful , thanks . Please update it .
Many buttons are only working after the second time you click them . Also the meta level does not affect the outcome of invention currently.
I also couldnt find some blueprints in the list, no tier 2 battlecruiser like drake harb.
Looking forward for an update, cheers.

Great app but i cant find harbinger or drake blueprints . Looks like there are only invent able blueprints . Although i also use this program to see how much a blueprint production would cost me .
Can you also add the missing blueprints into the program please ? Or can you guys suggest me another program that shows how much isk is required to build X blueprint with y skills and z ME . Thanks

Thanks for super sweet mod!
There is one thing that baffels me tho. Why is the Average profit per invetion job listed as THE number to compare profitability? This only makes sense if inventing was the bottleneck! However inventions are pretty fast.
The bottleneck in my production is producing and selling an item!!! Id therefor like a new number added to the bottom of the list wich is: PROFIT PER ITEM Simply calculated as Item price - Total cost of item. (wich includes building and inventing)
And if this number is added as a column to the main list we could sort by profitability on each item.
And for the love of god, pls rid us from the beep made whenever you select somthing.... --- Live and learn, die and learn more! http://www.dukefoss.com/eve/ |

Edited by: Mara Horn on 01/03/2010 21:48:22 There appears to be a problem with the build prices for anything that is made in lots greater than 1.
Example would be flameburst light missiles.
57trit x 2.5isk = 142.5 72pyer x 5isk = 360 total = 502 per 100 (5.01 per 1)
It comes up with a build price of 502, instead of 5.01. Which throws off the price and makes it appear that almost all ammo/missiles are unprofitable to produce the T1 versions.
The program is just not dividing by the portion size.

When looking at the build components for a Viator at ME-5, the calculator is overstating the materials needed. For example, the calculator tells me I need 150 construction blocks per run while the bpc in game is telling me I only need 120.

Hi, I recently discovered an error, which hasn't been reported yet. The error message appeared at program start. After closing the message window inventioncalculator started, but all the items where missing. I could navigate in all the menus whithout any problem. when I tried to close the inventioncalculator the message appeared again. I had to close the inventioncalculator by closing the command window. (cmd)
Message: "Access violation at address 004BB67F in module 'InventionCalculator.exe'. Read of address 0000001C."
After I deleted the whole folder "eec049d" and unzipped it from the rar archive again the error didn't happen again (yet).

Same, but somehow it screwed the calculations up, reset everything and i had some immensely high numbers for costs and when restarting it the error showed up again. |

I tried to extract the inventioncalculator to different hard discs. But after i set some prices, closed IC and opened it again, the error appeared again and again. no matter where the IC folder is extracted to.
I hope you can reproduce the error and hopefully fix it. i'd really like to use IC again. p.s. i'm using win XP

The calculator was last updated in 2009. Even then, there was plenty of erroneous and outdated information. It is even more so now. Unless anatolix continues to update, or Burchov comes back, it won't be changing. You could of course, work on it yourself if you know how to do that sort of thing. There are other options out there for doing invention calculations and tracking. Using this would be a good place to start, as I can't be arsed to find the threads for them. They are usually right here in the S&I forum though.
