در این مقاله یک مدل ریاضی برای مسئله سیستم تولیدی همکارانه ساخت بر اساس سفارش با رعایت انصاف تخصیص بار‌های تولید طراحی شده است. اهداف اصلی مدل، کمینه‌سازی هزینه‌‌های کل و حداکثر استفاده از منابع به‌منظور عادلانه شرایط عدم­قطعیت کنترل پارامتر‌های غیرقطعی روش برنامه‌ریزی فازی ‌شده نتایج نشان می‌دهد افزایش نرخ عدم‌قطعیت، می­یابد. ازآنجاکه ظرفیت کارخانه‌ها ثابت است، مقدار تقاضا، هر کارخانه نیز می­ی...

As security threats are increasingly diversified, a critical problem in Wireless Sensor Network environments (WSNs) is detecting anomalies. WSNs affected by several limitations, such as limited energy, insufficient memory, weak computation power, and short communication range. Hence, it necessary to improve the detection accuracy convergence speed of intrusion environments. In this article, we ...

This paper examines the dynamic connectedness among implied volatilities of oil prices (OVX) and fourteen other assets, which can be grouped into five different assets classes (i.e., energy commodities, stock markets, precious metals, exchange rates bond markets). To do so we estimate a recently developed time-varying parameter vector autoregressive (TVP-VAR) approach using daily data spanning ...

We investigate the topology of sectoral returns in US stock market using minimum spanning tree (MST) analysis. examine four distinct time periods: full period, Global Financial Crisis (GFC), COVID-19 pandemic, and Russia-Ukraine war period. By comparing static results across these periods, we identify differences network structure. Additionally, a rolling window analysis is conducted to explore...

This paper studies a modified Chinese Taylor’s rule with money supply growth rate as the intermediate target. We develop survey data to measure the expected inflation and use the real marginal cost as a proxy for the output gap. The Markov regime switching model, the TVP model and the split sample OLS estimation are employed to estimate the changing coefficients of the monetary reaction functio...

This note is concerned with the essential part of Finite Element Methods (FEM) approximation error analysis for quasi-Newtonian modelling thixo-viscoplastic (TVP) flow problems. The developed FEM settings thixotropic generalized Navier-Stokes equations based on a constrained monotonicity and continuity coupled system, which cornerstone an efficient monolithic Newton-multigrid solver. manifested...
