The (relative) cost of the customer’s waiting time has long been used as a key parameter in queueing models, but it can be difficult to estimate. Recently, Singhal, Singhal, and Kumar (2019) introduce a new queue characteristic, the value of the customer’s waiting time, which measures how an...

We have developed a measure of the value of the customer’s waiting time that is applicable to all queuing systems. Since the birth of the modern queuing theory over one hundred years ago, this measure is the first addition to the list of the measures of performance of general queues that...

We develop an easy-to-implement programmed method for generating new product ideas from existing products. In this method, whose core is a compatibility matrix, each pair of components or each pair of attributes used in a new design is already part of one or more existing products produced by...

We demonstrate that innovations in import and pivot goods usually cause the innovator’s trading partner to benefit and that few exceptions occur, and those mostly when the innovator has the larger economy or the higher per capita income. If the productivities of all goods in one country...

When consumers reallocate their spending on goods and expect their consumption to change proportionally, this expectation will not be fulfilled in a specialized equilibrium and the equilibria that follow it, with the result that one country’s income increases and the other country’s...

We generate a set of scenarios for project portfolios such that no single portfolio contains mutually exclusive projects while the set contains all such scenarios. We us the compatibility matrix, a method in the operations management literature, to generate project scenarios. We then go further,...

We consider advertising problems under an IT capacity constraint encountered by electronic retailers in a duopolistic setting. While there is a considerable amount of literature on advertising games between firms, introducing an IT capacity constraint fundamentally changes this problem. In the...

Health Information Exchanges (HIEs) are designed to improve the efficiency and quality of healthcare through enhanced information sharing between disparate health entities. The objective of this study is to systematically examine the impact of HIE use in emergency departments (EDs) on quality...

Identification of competitive healthcare providers is an important issue for successful operation of a bundled payment reimbursement program. We develop a healthcare provider selection framework via data envelopment analysis (DEA) and combinatorial auction (CA). Our goal is to cover target...
