Abstract We consider a lot-sizing problem with set-ups where the demands are uncertain, and propose novel approach to evaluate inventory costs. An interval uncertainty is assumed for demands. Between two consecutive production periods, adversary chooses set demand either its higher value or lower in order maximize (holding backlog) A mixed-integer model devised column-and-row generation algorit...

Two different bullwhip effects with equal scores may have different sensitivities and production patterns. As a result, the difference between these two seemingly equal scores has been ignored in previous methods (such as frequency response and moving average). So, the present study constructs a model of Inverse Network Data Envelopment Analysis, to introduce the relative and interval scores of...

In this paper, we analyze the impacts of joint energy and output prices uncertainties on the inputs demands in a mean-variance framework. We find that the concepts of elasticities and variance vulnerability play important roles in the comparative statics analysis. If the firms’ preferences exhibit variance vulnerability, increasing the variance of energy price will necessarily cause the risk av...

Resource reservation is an essential step to enable wireless data networks support a wide range of user demands. In this paper, we consider the problem joint resource in backhaul and Radio Access Network (RAN) based on statistics demands channel states, also network availability. The goal maximize sum expected traffic flow rates, subject link access point budget constraints, while minimizing ou...
