Chapter 5 Production Planning
Aggregate production planning is the process of determining (1) the timing and quantity of production, (2) the level of inventories, (3) the number of workers employed, and (4) the amount of overtime used for up to 12 months ahead. Production and inventories are stated in overall or aggregate quantities, such as number of automobiles without ...
Aggregate Production Planning
The process of Aggregate production planning applies the upper-level predictions to lower-level, production-floor scheduling and is most successful when applied to periods 2 to 18 months in the future. Plans generally either "chase" demand, adjusting the workforce accordingly, or are "level" plans, meaning that labor is comparatively ...

16.15 The Aggregate Production Function
In many applications, we want to understand how the aggregate production function responds to variations in the technology or other inputs. This is illustrated in Figure 16.9.An increase in, say, technology means that for a given level of the capital stock, more output is produced: the production function shifts upward as technology increases.
