'''生产'''（英文：'''Production'''）指的是 [[File:equipment.png|link=equipment]] [[装备]]的生产事项，即诸如坦克、枪支、飞机和船只等，其他诸如建筑、军事设施等属于[[建设]]事项。

== 工厂 ==
{{SVersion|1.9}}
共有三类工厂：

* {{icon|Civilian factory}} '''[[建设#民用工厂|民用工厂]]：'''进行[[建设]]（包括维修），[[贸易]]，生产[[建设#消费品|消费品]]，和支持[[情报机构|情报机构]]与其[[Intelligence agency#Agency upgrades|升级]]。
* {{icon|Military factory}} '''军用工厂：''' 生产步兵装备、支援装备、火炮和飞机。基础生产花费产出为固定值4.5[[File:Production cost.png|link=生产]]&nbsp;。该值也受[[File:Production_efficiency.png|22px|link=Production Efficiency]] 生产效率修正和产出修正影响<br/>因此产能公式为：<math>\text{产能} = (\text{基础产出} \cdot \text{产出修正}) \cdot \text{生产效率}</math>  <br/>举例说明，在50% [[File:Production_efficiency.png|22px|link=生产效率]] 生产效率修正与10% 工厂产出修正时，产能为 <math>({4.5} \cdot {1.10}) \cdot {0.50} = {2.475}</math>
* {{icon|Naval dockyard}} '''海军船坞：''' 生产船只、潜艇和运输船。 其基础产出为固定值[[File:Production cost (naval).png|link=Production]]&nbsp;2.5，但产出效率总能保持在100%。

对军用工厂和船坞的产出修正主要来自于集中或离散[[研究|工业科技]]，民用工厂的产出主要受建筑科技和[[法律与顾问#法案|法案]]影响。

== 生产线 ==
{{SVersion|1.8}}
*民用工厂生产事项可以{{see also|建设}}
*军用工厂和船坞的生产按照生产线划分，每条生产线只能生产一种型号的装备，至多同时有 150 个工厂可以被分配到同一条生产线上，同样的装备可以开启多条生产线。
*相比之下，同时参与建造舰船的的船坞的数目受到了限制，其数目为主力舰不超过5个、屏卫舰不超过10个、潜艇和运输船不超过15个。

==={{Anchor|production efficiency}} [[File:Production_efficiency.png|28px|link=Production Efficiency]] 生产效率 ===

[[File:Factory ramp losses.png|thumb|600px|right|生产损失 与 基础生产效率/最大生产效率比值 关系图。横轴为 基础生产效率/最大生产效率， 纵轴为生产损失。生产损失的衡量方法：损失了x天的（以最大生产效率进行生产时的）产量。]]

每条生产线的生产效率独立计算，生产效率越高则装备出产越快直到达到最大值，持续到生产作业会逐步提高生产效率。

装备投产后，生产效率从基础值开始（无修正状态下为 10%）并且逐步达到最大值（无修正状态下为 50%），这两项可以通过提升[[科研#工业科技|工业科技]]或切换[[法律与顾问#法案|法案]]进行提升提升。
每日效率增长为：<br>

<math>\text{每日效率增长}= 0.001 \frac{( \text{生产效率最大值} )^2}{\text{当前的生产效率}}</math><br>

（上述所有值都可以用百分数或小数表示，只要保证形式一致即可）<br>

最低每日生产效率增长为0.05%（接近基础生产效率的50%），最大为1%（10%/100%生产效率）。<br>

从另一角度来说，想要达到某一水平的生产效率所花天数为：<br>

<math>t = 500 \left( \frac{\text{生产效率}}{\text{生产效率最大值}} \right)^2</math><br>

举例说明，当前效率为生产效率上限的 25%， 欲达到生产效率上限的 75%， 需要花费<math>500 \cdot 0.75^2 - 500 \cdot 0.25^2 = 250</math> 天<br>

因此满足供应的生产线需要500天左右才能达到生产效率上限，满生产线情况下最大效率一组要比初始效率一组高出166.6工厂-日的水平。<br>

各个工厂的效率分别计算，新加入的工厂看似会降低生产效率，但原先参与生产的工厂的生产效率不会受到影响，即不会导致总生产效率的下降。<br>

'''注意'''：当失去军用工厂或其受到损害，被移除生产线的顺序是从列表下方开始的，将重要装备的生产置于列表上方是十足的明智之举。

==={{Anchor|production efficiency}} [[File:Production_efficiency.png|28px|link=Production Efficiency]] 生产效率保持===
同样，切换生产线上的产品会导致已有产出进度的损失，并且依据前后两种产品的类别远近损失一定的生产效率。<br>
可获保持的生产效率如下所示：

* {{red|{{hover|Defines NProduction BASE_FACTORY_EFFICIENCY_VARIANT_CHANGE_FACTOR|90%}}}}： 同种装备的不同 [[衍生型]] （例如Panzer IIIAusf. F -> Panzer III Ausf. G），这也包括从生产许可中获得的型号向自产的同型号装备转变的情况，例如（意大利战斗机 II C.202 霹雳 ->  德国战斗机 II FW190）
* {{red|{{hover|Defines NProduction BASE_FACTORY_EFFICIENCY_FAMILY_CHANGE_FACTOR|70%}}}}：同一级别不同种类的装备（例如Panzer III -> StuG III [1级德意志国中型坦克转为1级德意志坦克歼击车]）
* {{red|{{hover|Defines NProduction BASE_FACTORY_EFFICIENCY_PARENT_CHANGE_FACTOR|30%}}}}: 直接'''升级''' 或'''降级''' 同种装备（例如 Panzer III -> Panzer IV [1级德意志国中型坦克转为2级德意志国中型坦克]）
*{{red|{{hover|Defines NProduction BASE_FACTORY_EFFICIENCY_ARCHETYPE_CHANGE_FACTOR|20%}}}}: 非直接'''升级''' 或'''降级''' 同种装备（例如 Panzer III -> Panther [1级德意志国中型坦克转为3级德意志国中型坦克]）
* {{red|{{hover|Defines NProduction BASE_FACTORY_EFFICIENCY_BALANCE_FACTOR|10%}}}}: 其他形式的转变（例如1级步兵装备转为1级牵引火炮）

除了最后一种情况损失固定为 10%，其他情况下的损失可由升级科技抵消
* 离散型工业 I 到 IV
* 柔性生产线（1943年基础机床科技）
====生产效率保持的相关计算====

当一条生产线切换生产的产品时，如果拥有离散型工业或者柔性生产线科技，新的生产效率不会简单地保持如上所述的固定数值（上一段的{{red|红字}}内容），而是会保持更高的生产效率。按游戏中所述，效率的损失会按照百分比计算。例如，无修正下的生产效率保持（以下简称为生产效率保持）中，保持了10%相当于损失90%，所以拥有10%的生产效率保持加成会把90%的损失减少到90%*0.9=81%，这样修正后的生产效率保持将为1-81%=19%。

新的生产效率可以通过如下步骤得到。首先用生产效率保持加成和生产效率保持计算出实际生产效率损失，再用目前的生产效率乘以（1-实际生产效率损失）得到新的生产效率。注意最低的生产效率为10%，所以如果上述计算结果小于10%也会以10%的效率开始新的生产（这一基础生产效率也会受到科技影响）。以下为计算公式：

理论新生产效率 = 目前的生产效率 * （ 100% - （ 100% - 生产效率保持加成）*（ 100% - 生产效率保持 ））

例如一个目前为80%的生产效率的步枪生产线转产摩托化装备，拥有30%的生产效率保持加成，则理论新生产效率为80%*（100%-（100%-30%）*（100%-10%））=29.6%。

从上述公式可以看出，生产效率保持加成在生产效率保持较低的情况下，作用会较为明显。考虑到基础生产效率，则总结为：真正的新生产效率 = MAX ( 理论新生产效率，基础生产效率 ）。

船坞里生产的舰船、潜艇和运输船生产效率机制与军用工厂的不同，每次切换生产都会完全损失掉老的船只（无论建造进度如何），而新的船只也会直接以固定效率生产。每个船坞在无加成时生产效率为[[File:Production cost (naval).png|link=Production]] 2.5每日，这一数值也会受到工业科技或国家精神的影响。

== 战略资源 ==
{{SVersion|1.5}}
Each nation can use a percentage of the resources on its territory for military production. This percentage depends on the [[trade law]], with [[File:Closed Economy.png|20px|link=Closed Economy]]Closed Economy giving 100%.

The total amount of resources can be increased by researching the Excavation technologies (under the tab 'industry').   Each level of Excavation technology gives a resource gain efficiency increase of {{green|+10%}} to the total of all extracted resources (extracted resources are those that come from the ground via drilling or mining or that are produced via a Synthetic Refinery; it does not include resources from trade).  There are five (5) levels of Excavation technology; researching all of them will give a {{green|+50%}} bonus to the extracted resources total. 

The total amount of resources can also be increased by building infrastructure. Each level of infrastructure gives a resource increase to the total of all extracted resources (except those resources produced by a Synthetic Refinery or resources acquired via trade) in a state.  The increase varies with both the starting quantity of resources and starting level of infrastructure.  This is shown in the example table below for the resource Steel.

Resources cannot be stockpiled—they flow directly to production with any excess resources being effectively wasted. 

Different kinds of equipment require different resources to produce. Lacking sufficient resources will apply an increasing efficiency penalty up to {{red|-100%}} to the lowest priority production lines. The penalty increases by {{red|-5%}} per missing unit of resource per type and the highest applicable penalty is applied to individual factories. For example, when having 2 units of steel and 0 units of aluminum available and adding a new production line for Support Equipment (needs 2 steel, 1 aluminum) with 11 factories, the first factory receives a penalty of {{red|-5%}} because it misses one unit of aluminum. The second factory receives {{red|-10%}} penalty because it both misses two units of steel and the second unit of aluminum. For each of the remaining factories the penalty increases by {{red|-10%}} because they need two additional steel, the last one getting a {{red|-100%}} penalty. The production line shows the average penalty across all factories, {{red|-50%}}. This penalty stacks multiplicatively with other modifiers.

There are six strategic resources:

=== 战略资源获取 ===

There are several ways to acquire more resources:

* Trade for resources.
* Take [[resource prospecting decisions]] or certain [[national focus]]es.
* Construct Infrastructure in resource-producing states.
* Construct Synthetic Refineries.
* Change Trade Law to keep more domestic production.
* Research Extraction technology.
* Conquer states containing resources.
* Gain rights to resources

{{SVersion|1.5}}
Land divisions and air wings are not produced as atomic units. Instead, factories produce individual tanks, airplanes, and so forth. This equipment is then sent to fill out the country's land divisions and air wings. Unlike resources, equipment can be stockpiled. The stockpiles can be viewed under the Logistics Tab.

== 生产许可 ==
{{SVersion|1.8}}
{{expansion|dod}}
Nations may pay for production licenses from nations that already have researched a technology. The cost is generally 1 civilian factory. The factory goes to the nation whose equipment is being licensed. 

A nation with good relations with a foreign nation can request a license from them to produce the foreign equipment. The equipment type a nation is willing to license out is dependent on their relations. Germany, for example, may not be willing to license out their latest tank or fighter designs, but would be happy to provide Panzer IIs to friendly or neutral nations. National focuses may also provide a way to gain licenses or provide bonuses to license production. Producing licensed equipment will not be quite as efficient as producing the player's own designs. A cutting edge license production will have a noticeable output penalty, but a design a few years old will be almost as efficient to produce as a self-owned technology. If you aren't in the same faction as the owner of the design, you will also receive a little bit less technical support and manufacturing assistance.

Licensing equipment also gives a research bonus for the related technology if one is interested in unlocking it in the future.
