economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Problems for ’Mathematical methods in finance’

(non strict second order dominance) iff Eu(A) ≥ Eu(B) for all utility functions u on [a, b] such that u′ ≥ 0 and u′′ ≤ 0 . 3. Second order dominance and stop loss. Show that (1) holds (i) iff E(B−d)− ≥ E(A− d)− for all d ∈ [a, b] or (ii) iff Emin(d,B) ≤ Emin(d,A) for all d ∈ [a, b]. 4. Utility and ARA. (a) Show that there exists a unique utility function u on R with a given ARA ρ(x) and such th...

New Realities of the Enterprise Management System Information Support: Economic and Mathematical Models and Cloud Technologies

The paper focuses on the urgency of the implementation of cloud technologies, which are a necessary condition for the development of enterprise management systems, give rise to a complex of insufficiently studied phenomena and processes and determine the need to find new tools in making and implementing reasonable management decisions. In the process of research, the sequence of construction an...

Solving dynamic stochastic economic models by mathematical programming decomposition methods

Discrete-time optimal control problems arise naturally in many economic problems. Despite the rapid growth in computing power and new developments in the literature, many economic problems are still quite challenging to solve. Economists are aware of the limitations of some of these approaches for solving these problems due to memory and computational requirements. However, many of the economic...
