The present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using Markov Birth-Death process and probabilistic approach. In present paper, the feed water system consists of four subsystems. After drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...

Much of the production in firms takes place over time. This paper seeks to understand the value of interim performance information on long projects. In particular, the model explores the sorting effects of performance evaluations. Conducting an interim performance evaluation increases efficiency by providing the option to end projects with low early returns. The main result: It is efficient to ...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...
