The problem of customer demand satisfaction in production systems with unreliable machines and finite finished goods buffers (FGB) is addressed. The measure of customer demand satisfaction is characterized by the probability to ship to the customer a required number of parts during a fixed time interval. This measure, referred to as the due-time performance (DTP), is often used to characterize ...

There is a virtual consensus in contemporary epistemology that knowledge must be reliably pro­ duced. Everyone, it seems, is a reliabilist about knowledge in that sense. I present and defend two arguments that unreliable knowledge is possible. My first argument proceeds from an observation about the nature of achievements, namely, that achievements can proceed from unreliable abilities. My seco...

Population protocols are a model of distributed computation intended for the study networks independent computing agents with dynamic communication structure. Each agent has finite number states, and opportunities occur nondeterministically, allowing involved to change their states based on each other's states. In present paper we unreliable models population variations from point view expres...

Entanglement resources can increase transmission rates substantially. Unfortunately, entanglement is a fragile resource that quickly degraded by decoherence effects. In order to generate for optical communication, the transmitter and receiver first prepare entangled spin-photon pairs locally, then photon at sent through an fiber or free space. Without feedback, does not know whether has reached...
