Partial budget analysis is an effective production tool to evaluate economic implications of proposed changes to pig production systems. We describe a partial-budgeting tool that estimates the effects of lactation space and lactation-space management on net revenue in a multi-site production system. A partial-budgeting worksheet is linked to an economic model that couples production-system-spec...

Mechanism design enables a social planner to obtain a desired outcome by leveraging the players’ rationality and their beliefs. It is thus a fundamental, but yet unproven, intuition that the higher the level of rationality of the players, the better the set of obtainable outcomes. In this paper we prove this fundamental intuition for players with possibilistic beliefs, a model long considered i...

The evolving IS literature on business models for digital products assumes that the positive feedback effect will lead to price competition and biased concentration of the market. In theory, this will require companies to either differentiate or customize their products and services. In this paper we propose an empirical investigation of customization as a lock-in business strategy for online n...

With the rapid growth of broadband computer networks, users are inclined to use delivery services that can handle large-size content. When offering download service of popular contents, it is more useful to use a multicast system and deliver content to all users who request the content than using unicast system. Using a multicast system, the content server can increase the number of users and d...

E-commerce Web-servers often face overload conditions during which revenue-generating requests may be dropped or abandoned due to an increase in the browsing requests. In this paper we present a simple, yet effective, mechanism for overload control of E-commerce Web-servers. We develop an E-commerce workload model that separates the browsing requests from revenue-generating transaction requests...

We study robust formulations of assortment optimization problems under the multinomial logit choice model. The novel aspect of our formulations is that the true parameters of the logit model are assumed to be unknown, and we represent the set of likely parameter values by a compact uncertainty set. The objective is to find an assortment that maximizes the worst case expected revenue over all pa...

UNLABELLED We previously studied hospitals in the United States of America that are losing money despite limiting the hours that operating room (OR) staff are available to care for patients undergoing elective surgery. These hospitals routinely keep utilization relatively high to maximize revenue. We tested, using discrete-event computer simulation, whether increasing patient volume while being...
