Operating room (OR) scheduling is a critical factor affecting overall hospital performance. We examine OR scheduling from two perspectives. In the first perspective we propose a scheme for OR block scheduling that uses a heuristic developed for a three-machine flow shop where the three phases of...

In this research we model and estimate the effects on productivity downstream from information technology (IT) investments made upstream. Specifically, we examine how one industry's productivity is affected by the IT capital stock of its suppliers. These supplier-driven IT spillovers occur...

In many industries agent-intermediated markets are inefficient because information about latent demand and supply never gets to market. We demonstrate how information technology in the form of an agent-intermediated electronic market (EM) alleviates this problem by enhancing the...

In this research we study how existing market coverage affects the outcome of the Internet channel entry game between an existing retailer and a new entrant. A market is not covered when some consumers with low reservation prices are priced out by existing retailers and do not purchase. In a...

We propose a general and precise model of a network alliance that addresses both the role of membership and the role of incentives in the coordination of actions and interactions of network alliance members. Using examples in such disparate industries as professional engineering, accounting...

This paper demonstrates that globalization, taking the form of a higher import component of consumption and a larger export component of GDP, is the cause of the apparent breakdown in the relationship between excess demand and inflation. Within a parsimonious empirical framework, we show that...

Even though research in flow shop production scheduling has been carried out for many decades, there is still a gap between research and application — especially in manufacturing paradigms such as one-of- a-kind production (OKP) that intensely challenges real time adaptive production...

Blockchains allow firms and consumers to trace the physical flow of products along a supply chain. Although this improvement in information transparency helps enhance product safety and quality, it also provides information integration in the channel by giving an upstream manufacturer...

We propose a trade-off balancing (TOB) heuristic in a no-wait flow shop to minimize the weighted sum of maximum completion time (Cmax) and total completion time (TCT) based on machine idle times. We introduce a factorization scheme to construct the initial sequence based on current and future...

We study a two-echelon supply chain network consisting of manufacturers and retailers facing customers that differ in their price- and time-sensitivity. We examine how many price/lead time options should be provided by manufacturers and retailers under decentralized and centralized supply chain...
