We consider the planning of production over the infinite horizon in a system with time-varying convex production and inventory holding costs. This production lot size problem is frequently faced in industry where a forecast of future demand must be made and production is to be scheduled based on...

In this paper, we consider a shipping system consisting of one carrier and two shipping forwarders who compete on price for businesses from potential shippers. The carrier may quote different prices or a single price to the two shipping forwarders who will then order shipping capacity from the...

We consider multiunit Vickrey auctions for procurement in supply chain settings. This is the first paper that incorporates transportation costs into auctions in a complex supply network. We first introduce an auction mechanism that makes simultaneous production and transportation decisions so...

This paper examines two due-date setting problems first studied by Wein (1991). The first problem seeks to minimize the average due-date lead time (due-date minus arrival date) of jobs subject to a constraint on the fraction of tardy jobs (Problem I) while the second uses the same objective...

In this paper, we consider a buyer who designs a product and owns the brand, yet outsources the production to a supplier. Both the buyer and the supplier incur quality-related costs, e.g., costs of customer goodwill and future market share loss by the buyer and warranty-related costs shared by...

Most of the traditional models in production and inventory control ignore the financial states of an organization and can lead to infeasible practices in real systems. This paper is the first attempt to incorporate asset-based financing into production decisions. Instead of setting a known,...

Deceptive counterfeits differ from non-deceptive ones in that they are packaged and sold as authentic brand name products so that consumers may buy counterfeits unknowingly. When a distribution channel, referred to as the general channel, has been penetrated with deceptive counterfeits, a brand...

We consider non-sealed bid online auctions of common products with quantity uncertainty. Both first-price (also known as pay-as-you-bid) and uniform-price auctions are considered. In these auctions, all bidders have the same valuation of the products but may have different demand quantities. The...

We consider an infinite horizon production planning problem with nonstationary, convex production and inventory costs. Backlogging is allowed, unlike as in related previous work, and inventory cost is interpreted as backlogging cost when inventory is negative. We create finite horizon...
