When the demand is constant from period to period the lot-sizing problem is solved by the EOQ model, when the demand varies from period to period (i.e. "is dynamic") the appropriate model for the lot sizing problem is the Dynamic Lot Size Model. This usage is fairly standard in the literature. There are many other models as well, lot sizing is a general umbrella term, the specific assumptions vary with each model.
