Lean production
（リーン(やせた、ぜい肉をそぎおとす)生産方式:Lean production）
A philosophy of production that emphasizes the minimization of the amount of all the resources (including time) used in the various activities of the enterprise.
It involves identifying and eliminating non-value-adding activities in design, production, supply chain management, and dealing with the customers. Lean producers employ teams of multiskilled workers at all levels of the organization and use highly flexible, increasingly automated machines to produce volumes of products in potentially enormous variety.

Leveling Production and Schedules
（生産計画の平準化）
Heijunka is the leveling of production by both volume and product mix. It does not build products according to the actual flow of customer orders, Which can swing up and down wildly, but takes the total volume of orders in a period and levels them out so the same amount and mix are being made each day.
The problem with building to an actual production sequence is that it causes you to build parts irregularly.
To smooth this out, you take the actual customer demand, determine the pattern of volume and mix, and build a level schedule every day. For example , you know you are making five A's for every five B's. Now you can create a level production sequence of ABABAB. This is called leveled , mixed-model production , because you are mixing up production but also leveling the customer demand to a predictable sequence, which spreads out the different product types and levels volume.

line balancing
（ラインバランシング）
The balancing of the assignment of the elemental tasks of an assembly line to workstations to minimize the number of workstations and to minimize the total amount of idle time at all stations for a given output level. In balancing these tasks, the specified time requirement per unit of product for each task and its sequential relationship with the other tasks must be considered. 2) A technique for determining the product mix that can be run down an assembly line to provide a fairly consistent flow of work through that assembly line at the planned line rate.
