This paper includes a simulation model built in order to predict the performance indicessuch aswaiting time by analyzing queue’s components in the real world under uncertain and subjective situation. The objective of this paper is to predict the waiting time of each customer in an M/M/C queuing model. In this regard, to enable decision makers to obtain useful results with enough knowledge on th...

In clinical trials, multiple primary outcomes are often needed to assess the effectiveness of an intervention as a single primary outcome can be insufficient to describe all aspects of a complex disorder. These outcomes are often correlated. Many procedures for addressing multiple outcomes have been introduced; however, most of the commonly used methods do not make use of the correlations among...

This paper presents a mathematical model for an inventory control system in which customers’ demands and suppliers’ service time are considered as stochastic parameters. The proposed problem is solved through queuing theory for a single item. In this case, transitional probabilities are calculated in steady state. Afterward, the model is extended to the case of multi-item inventory systems. The...

The Meaning Maintenance Model (MMM; Heine, Proulx, & Vohs, 2006) proposes that human beings innately and automatically assemble mental representations of expected relations. The sense of global meaning that these relations provide is regularly disrupted by unrelated or unrelatable experiences, which elicit feelings of meaninglessness. People respond to these disruptions by engaging in meaning m...

Conventional methods have been criticized for their positivist philosophy and for either ignoring the organizational context of information systems development (ISD) or using only a simplistic, machine-based conceptual model of organizations. We have developed an approach to enable systems developers to use a richer view of organizations and a more interpretive approach. MultiMetaphor Method (M...

We predict by first-principles methods a phase transition in TiO2 at 6.5 Mbar from the Fe2P-type polymorph to a ten-coordinated structure with space group I4/mmm. This is the first report, to our knowledge, of the pressure-induced phase transition to the I4/mmm structure among all dioxide compounds. The I4/mmm structure was found to be up to 3.3% denser across all pressures investigated. Signif...
