Dynamic lot sizing example
WebThe dynamic lot-sizing problem under a time-varying environment considers new features of the production system where factors such as production setup cost, unit inventory-holding cost, and unit price of manufacturing resources may vary in different periods over the whole planning horizon. Traditional lot-sizing theorems and algorithms are no longer fit for … WebNov 28, 2004 · A two-echelon dynamic lot-sizing model with demand time windows and early and late delivery penalties with optimality properties is studied, providing polynomial time algorithms that require O(T3) computational complexity if backlogging is not allowed and O( T5) computationalcomplexity if backloging is allowed.
