We analyze a price-setting news-vendor problem with an additive – multiplicative demand. We show that the uni-modality of the news-vendor profit function holds when the underlying random term has an increasing failure rate and the demand functions satisfy certain concavity conditions....

We optimize a large country's currency supply network for its central bank. The central bank provides currency to all branches (who in turn serve consumers and commerce) through its network of big vaults, regional vaults, and retail vaults. The central bank intends to reduce its total...

Dynamic Stackelberg game models have been used to study sequential decision making in noncooperative games in various fields. In this paper we give relevant dynamic Stackelberg game models, and review their applications to operations management and marketing channels. A common feature of these...

Parallel machine structure is very common in modern production systems. Its performance sometimes has a decisive impact on the whole productivity. In this paper, we consider a parallel-machine scheduling problem where each machine is subject to periodic maintenance. Instead of assuming all the...

We study two competing firms with different production costs and moral standards making decisions to sell their products in the market by choosing their optimal production quantities and degrees of disobedience of a guiding rule imposed by a regulatory authority such as the government. We model...

This study investigates how random component yields can influence pricing and production decisions under pull and push contracts. We consider a decentralized assembly system where a manufacturer procures complementary components from two suppliers with random yields. We first characterize the...

Job shop scheduling with a bank of machines in parallel is important from both theoretical and practical points of review. Here we focus on a flexible job shop scheduling problem of minimizing the makespan in a two-center job shop, where the first center consists of one machine and the second...

We obtain optimal emission levels and abatement expenditures in a finite-horizon transboundary pollution game with emission trading between two regions.We show that emission trading has significant impact on the optimal strategies and profits of the two regions. We find that cooperation between...

We investigate a manufacturer's information acquisition and subsidization strategies in a supply chain featuring two competing retailers who sell substitutable products and have private demand information. The manufacturer can decide whether to acquire demand information at a cost and further...

Flow shop scheduling is common in modern lean production systems. In practice, jobs in flow shops can arrive at irregular times. However, scheduling that considers such irregularity has not been adequately investigated in the literature. In this paper, we examine the scheduling of n-jobs in an...
