How to Calculate Production Capacity of a Factory?
Sep 10, 2018· Answer: It is normal that the product types that you make will change from time to time. SAM of the same product may also change. Production capacity in pieces (dozen) will change accordingly - if the product SAM and line efficiency changes. The number of machines can be fixed, and one machine can be used for making one product at a time.

Reinforcement Schedules | Introduction to Psychology
Fixed ratios are better suited to optimize the quantity of output, whereas a fixed interval, in which the reward is not quantity based, can lead to a higher quality of output. In a variable ratio reinforcement schedule, the number of responses needed for a reward varies. This is the most powerful partial reinforcement schedule.
