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 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...

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...

Several problems, including the long-range process design problem, have been formulated as a compatibility matrix. Earlier, Singhal et al. (1988) proposed a partial enumeration algorithm which found all feasible designs and reported computational results. However, for large problems, the partial...
