Workshop Manufacturing

X-Com will need to build facilies to enable the manufacture of advanced weapons, crafts and devices, armors, etc. Constructing an item will allow a profit to be made when sold on the market. Optimising production allows larger profits!

Completion And Timing

Time to finish anything built is always completed on the hour. Small items with short build times should be optimised to best use the small workshop and five engineers, to complete a manufacturing run on the hour, however:

• multiple small items built over a multiple day production run, more efficiently use workshop space and engineer skills instead of short stop-start projects.
• massive projects, usually taking many days for just one item, may not profitable if those items can be recovered from a mission since higher-profit items should be X-Com's priority.
• An idle workshop is not making money!

Overheads

or, Costs Of Upkeep
Engineers receive a salary and maintenance of facilities (living and workshop) will reduce your profits by a certain amount, each and every week. Once a project's profit is calculated without interuption then matched with the size of the facility, profit totals will become more accurate:

• Small Workshop costs = 250

living quarters is half filled, so maintenance can be halved as well.

• Large Workshop costs = 500
  

Note: an idle workshop should make something even if it is barely profitable but flooding the market may turn it into a eventual loss.

Flooding The Market

Every item is (usually) profitable to manufacture, but your sell price is determined by market forces. If you sell so much (ie: flooding) that you drive the price down in the proceeding weeks, you will have to re-evaluate each manufacturing run using this new sell price of the new week, to find the best profits.
Items have differing amounts in the Market Capacity column which is a rough indicator of how many you can sell before you heavily influence the Sell Price towards its lowest value.
eg: selling x25 Dimension Missiles may slightly reduce the new-week sell price, but selling x25 Disruptor Guns will be classed as 'flooding' and will drive the sell price down, faster with a 'flood' every consecutive new week.

Profit Per Build Time

The only important thing!
The higher the decimal number, the better the profit. The best item may not be researched yet! Find another suitable item from your current manufacturing list.

Note: Everything is profitable (no negative decimals) as default until you start flooding!

Chart Definitions

• Manfacture: no know = no no
• Build Cost: internal cost to build one item
• Build Time: one unit
• Build Time: one unit in hours (rounded up) to make it easier to understand.
• Facility: small (250/week) or large (500/week)
• Market Capacity: how much to sell before price gets affected every week.
• Sell Price: what you get for each thing.
• Raw Profits: sell one-something to get this many credit-dollars, without paying your way.
• Profit Per Build Time: portion of a credit-dollar you get for each tick of the build clock.
