lot-sizing 发表评论(0) 编辑词条
In the standard dynamic lot-sizing model with backlogging, a study horizon
of n distinct periods (1, . . . , n} is given, each with a nonnegative demand for
a single commodity. The demand in any given period may be satisfied by production
in that period, in any earlier period (by carrying inventory), in later
periods (through backlogging), or by a combination thereof. The production
costs in each period consist of a fixed and a variable (linear) component, while
each period’s inventory-carrying and backlogging costs are assumed to be proportional
with the period’s ending inventory level and backlog size, respectively.
All cost parameters may be time dependent.
