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...

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...

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...

As consumer preferences rapidly evolve with respect to health-related attributes of food, many have questioned the performance of the conventional food industry to fulfill new demand. As the structure of the industry has shifted toward conditions where retailers have access to and incentive to...

A key feature of food products is their perishability. Within the short marketing window that characterizes most food and ag products, demand is typically highly stochastic and difficult to predict. This combination of features poses substantial challenges to retailers when pricing products and...

This paper proposes a model to determine the optimal investment time for energy storage systems (ESSs) in a price arbitrage trade application under conditions of uncertainty over future profits. The adoption of ESSs can generate profits from price arbitrage trade, which are uncertain because the...

This paper recognizes that in many decision environments in which revenue optimization is attempted, an actual demand curve and its parameters are generally unobservable. Herein, we describe the dynamics of demand as a continuous time differential equation based on an evolutionary game theory...

This paper proposes a methodology to generate a robust logistics plan that can mitigate demand uncertainty in humanitarian relief supply chains. More specifically, we apply robust optimization (RO) for dynamically assigning emergency response and evacuation traffic flow problems with time...

In this paper we present a continuous-time network loading procedure based on the Lighthill–Whitham–Richards model proposed by Lighthill and Whitham (1955) and Richards (1956). A system of differential algebraic equations (DAEs) is proposed for describing traffic flow propagation, travel...
