in any supply chain, distribution planning of products is of great importance to managers. with effective and flexible distribution planning, mangers can increase the efficiency of time, place, and delivery utility of whole supply chain. in this paper, inventory routing problem (irp) is applied to distribution planning of perishable products in a supply chain. the studied supply chain is compos...

e establish lower bounds on the minimum costs of managing certain productiondistribution networks with setup costs at all stages and stochastic demands. These networks include serial, assembly, and one-warehouse multi-retailer systems. We obtain the bounds through novel cost-allocation schemes. We evaluate the bounds' performance for one-warehouse multi-retailer systems by comparing them with s...

This paper presents a comparative cost performance study of four inventory models. One of them, referred as Requirement Planning, operates using demand forecast to quantify the acquisition decisions. The other three inventory models are the Order Up to Maximum Inventory Level, Base Stock and Fixed Lot Size. The Requirement Planning and Base Stock models operate with minimal purchase order quant...

tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. hence, integration has been proposed to decide about these problems concurrently. main problem in integration is how we can relate pro...

In this paper, we present a corrugation software features and its related development issues. Typically, in a paper corrugation factory, such a software is very important. The main features in the software is the paper roll inventory management and paper roll selection planning. The inventory management includes the stocking of the paper rolls. The roll selection plan involves creating a roll s...

We formalize a simple but natural subclass of service domains for relational planning problems with object-centered, independent exogenous events and additive rewards capturing, for example, problems in inventory control. Focusing on this subclass, we present a new symbolic planning algorithm which is the first algorithm that has explicit performance guarantees for relational MDPs with exogenou...

In this study, we explore the use of information for inventory decision in the healthcare organization (HO). We consider the scenario when the HO can make use of the information collected from some correlated products to enhance its inventory planning. Motivated by our real world observations that HOs adopt RFID and bar-coding system for information collection purpose, we examine the effectiven...
