Four equivalent lot-sizing models
We study the following lot-sizing models that recently appeared in the literature: a lotsizing model with a remanufacturing option, a lot-sizing model with production time windows, and a lot-sizing model with cumulative capacities. We show the equivalence of these models with a classical model: the lot-sizing model with inventory bounds.
متن کاملSome New Dynamic Economic Lot Sizing Models
We introduce a dynamic economic lot sizing problem whose production cost considers both setup and the designed-and-yet stretchable production capacity. Demands and the control on production activities drive the evolution of the production system. We give a pseudo-polynomial algorithm for the problem when future demands are known. When there is uncertainty in future demands and there is no holdi...
متن کاملCapacitated lot sizing models: a literature review
In the present paper, we discuss one of the many processes arising in the context of supply chain management, namely production planning. We focus on one type of production planning models called capacitated lot sizing models. These models appear to be well suited for the usually rather in exible production resources found in the process industries. We review the literature on single-level sing...
متن کاملErgo-Lot-Sizing: Considering Ergonomics in Lot-Sizing Decisions
One aspect that has mostly been overlooked in traditional economic lot-sizing is the implication of decisions on manual tasks and workload. Although lot-sizing decisions can have a significant impact on required manual material handling and on human performance, works that consider ergonomic aspects in lot-sizing are rare. This paper presents a model that integrates ergonomic aspect in terms of...
متن کاملEconomic lot-sizing games
In this paper we introduce a new class of OR games: economic lot-sizing (ELS) games. There are a number of retailers that have a known demand for a fixed number of periods. To satisfy demand the retailers order products at the same manufacturer. By placing joint orders instead of individual orders, costs can be reduced and a cooperative game arises. In this paper we show that ELS games are bala...
