Deciding shipment size is important in freight transport: it depends on the logistical imperatives of shippers and the technical possibilities of carriers. Shipment size choice is also closely related to transportation mode; it is therefore important from a public policy perspective. The theory of optimal shipment size and mode choice is robust. There are many inventory-theoretical models of op...

So far, inventory control for PP and LDPE products Supprise Kapsul at PT XYZ has been carried out with the assumption that practitioners are not academics, an average approach of last three months. For this reason, researchers implemented raw material using EOQ JIT/EOQ methods. By evaluative research method, sample is in form operational materials, type data documentation, source primary obtain...

This study aims to determine the optimal frequency of purchasing raw materials for Cup 220 ml and Straw using Economic Order Quantity (EOQ) method at PT. Bandangantirta Agung, Harvest Dew Prosperity Mandrapurna Aditama. The type data used is quantitative data, with qualitative research methods. results obtained purchases from three companies, PT Panen Embun Kemakmuran which get compared other c...

a r t i c l e i n f o This paper expands an inventory model for deteriorating items with stock-dependent demand. This model provides time varying backlogging rate as well as time varying deterioration rate. The aim of this model is to determine the optimal cycle length of each product such that the expected total cost (holding, shortage, ordering, deterioration and opportunity cost) is minimize...

In supply chains, domestic and global, a producer must decide on an optimal quantity of items to order from suppliers and at what inventory level to place this order (the EOQ problem). We discuss how to modify the EOQ in the face of failures and recoveries by the supplier. This is the EOQ with disruption problem (EOQD). The supplier makes transitions between being capable and not being capable ...

We consider a continuous review inventory system that faces two different cases of demand processes. In one case demand follows a compound Poisson process. In the other case demand is a combination of a constant deterministic component and a random component which follows a compound Poisson process. We assume negligible lead time. Orders occur when inventory level drops to or below level zero, ...

In this paper, we provide analytical support for the notion that it may be possible, via operational adjustments alone, to significantly reduce emissions without significantly increasing cost. Using the EOQ model, we provide a condition under which it is possible to reduce emissions by modifying order quantities. We also provide conditions under which the relative reduction in emissions is grea...
