Identify (a) the demand options for aggregate planning; and (b) the capacity (supply) options for aggregate planning

What will be an ideal response?

(a) Demand options are: influencing demand (through price, promotion, advertising, selling), back ordering during high-demand periods, and counterseasonal product and service mixing. (b) Capacity options are: changing inventory levels, varying workforce size by hiring or layoffs, varying production rates through overtime or idle time, subcontracting, and using part-time workers.
