Quality of decisions in inventory management models depends on the accuracy of parameter estimates used for decision making. In many situations, error in decision making is unavoidable. In such cases, sensitivity analysis is necessary for better implementation of the model. Though the newsvendor...

We propose tests for equality of treatment effects in the context of a double-blind 2 x 2 cross-over trial which do not require treatment codes to be unblinded and thus can be used as a part of the interim analyses. We first discuss the set-up of a 2 x 2 cross-over trial and state the important...

In this paper, we examine the possibility of quickly deciding whether or not an instance of a binary knapsack problem is difficult for branch and bound algorithms. We first observe that the distribution of the objective function values is smooth and unimodal. We define a measure of difficulty of...

We propose a penalized splines based method to predict the pathological stage of localized prostate cancer. A combination of prostate specific antigen, Gleason histological score, and clinical stage from a cohort study of 834 prostate cancer patients are used to build the penalized splines...

Due to the preference of satiation (of the profit target) over maximization (of expected profit) in uncertain situations, the newsboy problem with the satiation objective is an important practical problem. In the multi-product setting, practically usable solution methods are available only for...

Meeting the profit target is often preferred over maximizing expected profit in uncertain business environments. Research into the newsboy problem with satiation objective started quite early. However, the progress has been slow, particularly in the multi-product setting. We study the genral...

Preference of satiation of a target performance over maximization of expected performance in uncertain situations is well-documented in the economics literature. However, the newsboy problem with satiation (of a prot target) objective has not received its due attention. In the multi-product...

Meeting the prot target is often preferred over maximizing expected prot in uncertain business environments. Research into the newsboy problem with satiation objective started quite early. However, the progress has been slow, particularly in the multi-product setting. We study the general...
