This study revisits a fuzzy rough economic order quantity (EOQ) model for deteriorating items considering quantity discount and prepayment. Since the proposedmodel is amixed integer nonlinear programming type, it is solved using Meta heuristic algorithms. Based on three different case examples, we have shown that our results using the Bees Colony Optimization (BCO) algorithm performs better tha...

In this paper we propose a multivariate discount weighted regression technique to give a tractable solution to the problem of variance estimation and forecasting for the multivariate local level model. We give the correspondence between discount regression and matrix normal dynamic linear models and we show that the local level model can be treated with discount regression techniques. We illust...

We examine a simple repeated principal-agent model with discounting. There are a risk averse borrower with an unobservable random income and a risk neutral lender. The efficient contract is characterized. It tends to the first-best (constant consumption) contract as the discount factor tends to one and the time horizon extends to infinity. I f the time horizon is infinite and the contract is le...

Considering the probability of the logistics business successfully completed is influenced by the effort level of 4PL and 3PL, it will cause bilateral moral risk in the case that both sides of the factors of production cannot be checked. Using the principal-agent theory, the paper discusses both sides contracts in the centralized decision and distributed decision, founding that short-term contr...

In this paper, we analyze the impact of supplier pricing schemes and supplier capacity limitations on the optimal sourcing policy for a single firm. We consider the situation where the total quantity to be procured for a single period is known by the firm and communicated to the supplier set. In response to this communication, each supplier quotes a price and a capacity limit in terms of a maxi...

Supply chain management is concerned with the coordination of different parts of the production system. Companies have realized that they must closely collaborate with the suppliers of their strategic components or products. Recently, developing integrated inventory models for the supplier selection problem has attracted a significant amount of attention amongst researchers. In these models som...

The single-vendor single-buyer integrated production inventory system has been an object of study for a long time, but little is known about the effect of investing in reducing ordering cost on the integrated inventory models with backorder price discount and variable lead time. The purpose of this article is to investigate in the continuous review model with backorder price discount and variab...

This paper examines the impact of group purchasing organizations (GPOs) on healthcare8 product supply chains. The supply chain we examine consists of a profit-maximizing manufacturer with a 9 quantity-discount schedule that is nonincreasing in quantity and ensures nondecreasing revenue, a profit10 maximizing GPO, a competitive source selling at a fixed unit price, and n providers (e.g., hospita...

We consider the capacity allocation in a decentralized distribution system with a continuum of retailers, a number of distributors, and a supplier. Retailers privately observe their local demands, and distributors are equipped with information technology that facilitates finer prediction of retailers’ demands. The supplier builds capacity, but observes neither local demands nor the precision of...
