This research investigates how the experience learned in repeated transactions by consumers and manufacturers would affect supply-chain partners' strategic decisions such as price, order quantity and service level. Consumer demand depends on two factors: (1) retailer price and (2) service level...

Although life-testing of parallel systems provides more information than testing series systems, it can be very time consuming, which limits its usage in practice. In this article, a new plan of life-testing two-component (A and B) parallel systems is proposed. This plan terminates life-testing...

In this article, statistical properties of an absolutely continuous bivariate exponential model due to Gumbel (1960) are examined and the Fisher information matrix is derived. Simple estimators are motivated from a structural representation of the model and are compared both in terms of...

Stochastic processes observed over space often exhibit nonstationarity. Possible causes of nonstationarity include mean drift, heterogeneity of responses, or a correlation pattern that is not simply a function of the Euclidean distance between two spatial locations. This paper considers the...

This article derives the asymptotic results of the maximum-likelihood estimates of the parameters in the general bivariate continuous distribution for the data type, in which the failure time and the censoring variables are dependent. This data type is motivated from life-testing two-component...

This study addresses an integrated facility location and inventory allocation problem considering transportation cost discounts. Specifically, this article considers two types of transportation discounts simultaneously: quantity discounts for inbound transportation cost and distance discounts...

This article studies a container drayage problem with flexible orders defined by using requiring and releasing attributes as a unified formulation of various order types. A determined-activities-on-vertex (DAOV) graph introduces a temporary vertex set to formulate different truck statuses. The...
