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 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,...

Due to economic and physical resource constraints, it is not feasible to continually expand transportation infrastructures to adequately support the rapid growth in the usages of these infrastructures. This is especially true for traffic coordination systems where the expansion of the road...

Software patch management has now assumed tremendous significance and it directly affects the customer opinion about the quality and security of the released product. Hence, software vendors are forced to put in substantial amount of effort for servicing released products, and maintain a fairly...
