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...

This research aims to develop a multiple-choice Web-based quiz-game-like formative assessment system, named GAM-WATA. The unique design of ‘Ask-Hint Strategy’ turns the Web-based formative assessment into an online quiz game. ‘Ask-Hint Strategy’ is composed of ‘Prune Strategy’ and ‘Call-in Strategy’. ‘Prune Strategy’ removes one incorrect option and turns the original 4-option item into a 3-opt...

Let q = p, p a prime number. Let B m = Fq[X1, . . . , Xm]/(X q 1 −X1, . . . , X m −Xm); B m actually consists of all the functions from Fq to Fq. We identify B q m with F q q through the application B m → F m q P 7→ (P x∈Fmq For all b ∈ Fq , we denote by 1b the function in B m such that 1b(b) = 1 and for all x 6= b, 1b(x) = 0. The weight |P | of P ∈ B m is Card({x, P (x) 6= 0}). The Hamming dis...

In order to accurately explore the relationship between density of Engraulis japonicus and environmental factors, five types models, including Tweedie-Generalized Additive Model (GAM), two-stage GAM, Ad hoc-GAM, Generalized Mixing (GAMM), were compared based on survey data in offshore waters southern Zhejiang, China from 2015 2021 this study. The results showed best goodness fit for GAM when pr...

Equations describing eigenmodes with the frequencies of the order of the geodesic acoustic frequency and the electron/ion diamagnetic frequency in toroidal plasmas are derived and analyzed, a code BOAS solving them is developed. It is shown that there exist drift-sound eigenmodes and new drift-Alfvén eigenmodes. This is done by means of an analytical consideration and numerical modelling of par...

the relationship between topography, land use, and topsoil moisture storage is investigated for a small catchment with undulating deep loess hilslopes in the south of the netherlands. for a period of 10 months, soil moisture profiles have been measured weekly at 15 locations throughout the catchment. a generalized additive model was employed to find relationships between the various factors inf...

[1] The future carbon balance of high-latitude ecosystems is dependent on the sensitivity of biological processes (photosynthesis and respiration) to the physical changes occurring with permafrost thaw. Predicting C exchange in these ecosystems is difficult because the thawing of permafrost is a heterogeneous process that creates a complex landscape. We measured net ecosystem exchange of C usin...
