In this paper, we present a dynamic model modified with emission permit banking and pollution abatement, and investigate the effect of emission permit banking and pollution abatement on the production–inventory strategy of the firm. After introducing emission permit banking and pollution abatement, the cost function consists of the inventory holding and production costs, the cost of investment ...

The paper provides a new approach to study the problem of optimal control of two-item inventory model with deteriorating items. The total cost includes the sum of the holding costs of inventory, the holding costs of one item due to the presence of other and the production costs. The solution of optimal control problem of two-item model will be carried out using Pontrygin principle. The controll...

It is important to know to what extent the outcome of an LCA is affected by various types of uncertainty, such as parameter, scenario and model uncertainty. These types may occur in the goal and scope definition, the inventory analysis and the impact assessment of an LCA. Information on the uncertainty of the model outcomes provides useful information to assess the reliability of LCA-based deci...

The cooperation strategy followed by the buyer and vendor results is an overall effect on the saving percentage along with the impact of inventory costs such as holding cost, fixed and linear backorder cost. This paper deals with buyer vendor incentive inventory model with fixed lifetime product with fixed and linear back order cost. A distinguishing feature of this model is that both fixed and...

We investigate the strategic impact of flexible delivery frequencies on the competition of logistics service providers (LSPs) in a supply chain. LSPs compete for customers who choose an exclusive service provider based on their individual preference, prices and inventory costs. The service provider which offers the higher delivery frequency is more attractive to customers, because inventory hol...

we present an improved implementation of the wagner-whitin algorithm for economic lot-sizing problems based on the planning-horizon theorem and the economic- part-period concept. the proposed method of this paper reduces the burden of the computations significantly in two different cases. we first assume there is no backlogging and inventory holding and set-up costs are fixed. the second model ...

Probabilistic model; Inventory; Varying order cost; Holding cost; Lead-time demand; Uniform distribution; Safety stock Abstract This paper discusses the probabilistic backorders inventory system when the order cost unit is a function of the order quantity. Our objective is to minimize the expected annual total cost under a restriction on the expected annual holding cost when the lead time deman...

Joint replenishment problem (JRP) is a common real problem which aims to minimize order cost and inventory holding cost. In this paper, classical, centralized and decentralized JRP models are discussed. An innovative heuristic to minimize the total cost is implemented for each model. This heuristic seeks to balance the order cost and the inventory holding costs. The results show that the innova...
