We consider a dynamic inventory (production) model with general order (production) costs and excess demand that can be backordered or refused by the firm. A unit backordered incurs a backorder cost, a unit refused incurs a lost sales charge. Endogenizing the sales decision is necessary in the...

We derive a general approximation to the distribution of count data based on the first two moments of the underlying interarrival distribution. The result is a variant of the Birnbaum-Saunders (BISA) distribution. This distribution behaves like the lognormal in several respects; however, we show...

We investigate analytical and empirical properties of the Heteroscedastic Exponomial Choice (HEC) model to lay the groundwork for its use in theoretical and empirical research that build demand models on a discrete choice foundation. The HEC model generalizes the Exponomial Choice (EC) model by...

We investigate the use of a canonical version of a discrete choice model due to Daganzo (1979) in optimal pricing and assortment planning. In contrast to multinomial and nested logit (the prevailing choice models used for optimizing prices and assortments), this model assumes a negatively skewed...

We develop a framework to model the shopping and consumption decisions of forward-looking consumers. Assuming that the consumer’s future utility for each product alternative can be characterized by a standard random utility model, we use dynamic programming to determine the optimal consumption...

We develop an appointment scheduling model for a healthcare clinic that includes an upper bound on expected patient wait times. We refer to the schedule it produces as an equitable schedule. The operating environment of our focal clinic included three complicating features, all of which are...

Problem definition: Faced with the challenge of serving beneficiaries with heterogeneous needs and under budget constrains, a number of nonprofit organizations (NPOs) have come up with an innovative solution: providing partially complete products or services to beneficiaries. We seek to...

Firms developing novel and innovative products regularly face a canonical product development and introduction problem: introduce a proven and immediately available product, or delay product introduction until the successful development of an advanced version. Limited access to resources for the...

For products developed through a collaboration of specialized groups, success requires craft and engineering ingenuity from designers who focus on specific attributes, coupled with synchronized coordination between various design groups. We study the relationship between a development team's...

Reward-based crowdfunding allows entrepreneurs (creators) to raise capital through campaigns, where potential consumers (backers) pledge small amounts of funds. A key operational decision for a creator is the reward structure of a campaign, that is, the number of rewards and their contribution...
