We consider a critically-loaded multiclass queueing control problem with model uncertainty. The consists of I types customers and single server. At any time instant, decision-maker (DM) allocates the server’s effort to customers. DM’s goal is minimize convex holding cost that accounts for ambiguity respect model, i.e., arrival service rates. For this, we an adversary player whose role choose wo...

Hotel website service quality evaluation has gained extensive attention. However, previous studies have given little concern about human hesitance and uncertainty in judgments. Moreover, they do not consider hotel managers customers’ psychological behaviors simultaneously. This study explores criteria for evaluating performance proposes a hybrid model the hesitation of economy websites, applied...

A method for representing and manipulating imprecise and vague information in engineering design is described. Designers and customers preferences are captured with Fuzzy sets. Formal methods for including noise, trade-o strategies and design iteration are included. Introduction Imprecision and vagueness are intrinsic aspects of engineering design. If (at the start of a design process) a propos...

Residential customers use more than one-quarter of the electricity in world. Optimally managing home energy consumption is an effective way easing operational challenges facing electric grid with increasing solar photovoltaics (PV). This paper studies impact future proliferation management systems (HEMS) presence PV on large-scale distribution systems. First, we present a stochastic HEMS model ...

We consider how to partition arriving customers into service groups that will be served separately , in a rst-come rst-served manner, by multi-server service systems having a provision for waiting, and how to assign an appropriate number of servers to each group. We assume that customers can be classiied upon arrival, possibly according to their service requirements. We model the congestion exp...
