Guides to Inventory Policy: Functions and Lot Sizes

چکیده
But this is only one of the characteristic problems business managers face in dealing with production planning, scheduling, keeping inventories in hand, and expediting. Other questions just as perplexing and baffling when managers approach them on the basis of intuition and pencil work alone-are: How often should we reorder, or how should we adjust production, when sales are uncertain? What capacity levels should we set for job shop operations? How do we plan production and procurement for seasonal sales? And so on, and so on.

An Integrated Production-Inventory Model with Backorder and Lot for Lot Policy
inventory model, backorder buyer , vendor, lot for lot policy In this paper, an inventory model for two-stage supply chain is investigated. A supply chain with single vendor and single buyer is considered. We assume that shortage as a backorder is allowed for the buyer and the vendor makes the production set up every time the buyer places an order and supplies on a lot for lot basis...
متن کاملA Flow shop Production Planning Problem with basic period policy and Sequence Dependent set up times
Many authors have examined lot sizing, scheduling and sequence of multi-product flow shops, but most of them have assumed that set up times are independent of sequence. Whereas dependence of set up times to sequence is more common in practice. Hence, in this paper, we examine the discussed problem with hypothesis of dependence of set up times to sequence and cyclic schedule policy in basic peri...
متن کاملApproximate solutions for a stochastic lot-sizing problem with partial customer-order information
We address a stochastic single item production system in a make-to-stock environment with partial knowledge on future demand resulting from customers ordering in advance of their actual needs. The problem consists of determining the optimal size of a production lot to replenish inventory, so that delivery promises are met on time at the expense of minimal average costs. For this problem an opti...
متن کاملIncorporating Return on Inventory Investment into Joint Lot-Sizing and Price Discriminating Decisions: A Fuzzy Chance Constraint Programming Model
Coordination of market decisions with other aspects of operations management such as production and inventory decisions has long been a meticulous research issue in supply chain management. Generally, changes to the original lot-sizing policy stimulated by market prices may impose remarkable deviation revenue throughout the supply and demand chain system. This paper examines how to set the chan...
متن کاملEPQ model with scrap and backordering under Vendor managed inventory policy
This paper presents the economic production quantity (EPQ) models for the imperfect quality items produced with/without the presence of shortage condition. The models are presented in a two-level supply chain composed of a single manufacturer and a single buyer to investigate the performance of vendormanaged inventory (VMI) policy. The total costs are minimized to obtain the optimal production ...
