This paper considers a two-level supply chain consisting of a manufacturer and two buyers. The manufacturer produces one type of products at a finite rate and replenishes them to the buyers. Each buyer’s demand is sensitive to his selling price and the backorder is allowed at the buyers. Moreover, it is assumed that the buyers delay paying for goods to the manufacturer and two types of delay in...

The offer of a delayed period for payment from suppliers may help retailers to order more but also improve the total supply chain performance. In this paper, we adopt Conditional Value-at-Risk, CVaR, as the performance criterion to examine how supply chain performance is affected through the deferred payment contract. Analytical results are yielded for the newsvendor retailer’s optimal order qu...

A study was undertaken in southern peninsular state of India, the Tamil Nadu State, to assess the farmers’ “Willingness to pay” (WTP) for receiving annual health care services to their dairy animals. The districts of the state were categorized as “Livestock developed” (LD) and “Livestock under developed” (LUD) based on initial base line developed. Contingent valuation (CV) approach was used to ...

In this paper, we investigate the problem of determining a retailer’s optimal cycle time and the optimal payment policy when supplier offers partially or fully permissible delay in payment linking to payment time. The retailer can obtain the larger fraction of the delay payment permitted by the supplier when the retailer chooses the shorter delayed payment period. The supplier uses this policy ...

The hypothesis that the fixed component of a share contract serves as a risk premium is tested using a sample of contracts from the motion-pictures industry. The evidence refutes the risk-premium hypothesis under a variety of assumptions about the relative risk averseness of the players. Alternative explanations for the role of a fixed payment in two-part tariff contract design

A deterministic inventory model with two levels of storage (own warehouse and rented warehouse) with non-instantaneous deteriorating items is studied. The supplier offers the retailer a trade credit period to settle the amount. Different scenarios based on the deterioration and the trade credit period have been considered. In this article, we have framed two models considering single warehouse ...

In cognitive radio networks (CRNs), spectrum trading is an efficient way for secondary users (SUs) to achieve dynamic spectrum access and to bring economic benefits for the primary users (PUs). Existing methods requires full payment from SU, which blocked many potential “buyers”, and thus limited the PU’s expected income. To better improve PUs’ revenue from spectrum trading in a CRN, we introdu...

We develop an inventory model to determine optimal ordering policy under permissible delay in payment by considering demand rate to be stock dependent. Mathematical models are derived under two different cases: credit period being greater than or equal to cycle time for settling the account, and credit period being less than or equal to cycle time for settling the account. The results are illus...
