This paper presents a continuous time optimization model for a dynamic pricing and inventory control problem in a dual-channel supply chain system. We consider a manufacturer's redesign of traditional channel structures, based on customer behaviors, by engaging in direct Internet sales. While...

This paper examines supply contract negotiation when buyer's revenue and seller's cost are uncertain. In these circumstances, both the seller and the buyer have an option to determine when to sell and buy, which may influence negotiation outcomes. Thus, we developed a bilateral negotiation model...

Even though many studies have discussed outsourcing contracts from the client's perspective, little research has been done from the vendor's perspective. In this paper, we consider a vendor's outsourcing contract decision-making process, during which the market price and the vendor's operation...

A crucial question in a supply chain is whether to construct an internet channel in addition to a traditional retail channel. Despite many studies on this issue, little attention has been paid to optimal investment timing for developing the internet channel. To address this gap in the...

This paper addresses certain misconceptions regarding what is known and what may be expected when performing sensitivity analyses of network user equilibrium flow patterns. Our presentation relies on a simple observation: any given user equilibrium sensitivity analysis technique should be...

Many large shippers procure truckload (TL) service from carriers via a combinatorial auction. In order to determine the winners of the auction, they need to solve a combinatorial optimization problem known as winner determination problem (WDP). In practice, shippers must resolve the WDP under...
