In the era of economic globalization, the competition of product in the market does not depend on a certain enterprise. The traditional competition among different enterprises has transitioned to the competition among different supply chains. In order to win in the global competition, enterprises tend to implement supply chain process reengineering to enhance the coordination among all supply c...
A convolutional two-level hidden Markov model is defined and evaluated. The bottom level contains an unobserved categorical Markov chain, and given the variables in this level the middle level contains unobserved conditionally independent Gaussian variables. The top level contains observable variables that are a convolution of the variables in the middle level plus additive Gaussian errors. The...
در دهه ی گذشته مخابرات مشارکتی برای غلبه بر کاستی های ارتباطات بی سیم از طریق افزایش قابلیت اطمینان سیستم, افزایش مرتبه چندگانگی سیستم و کاهش توان ارسالی نسبت به حالت انتقال مستقیم, توجه زیادی را به خود جلب کرده است. رله های مشارکتی با ایجاد چندین منبع مجازی که همان اطلاعات منبع اصلی را انتقال می دهند باعث می شوند که در گره مقصد نمونه های متعدد مستقلی از سیگنال ارسالی از منبع را دریافت ...
In this paper, the hybrid modeling of Input-Output framework and MICMAC technique have been used to evaluates the inter-sectoral interactions between all sectors and activities of Iran’s economy based on the statistics aggregate Input-Output tables for five periods from 1973 to 2011. The main 15 sectors are elaborated and the results of the interactions were used to extract sectoral prioriti...
Global value chains are a complex product of the international fragmentation of production expansion that has revolutionized the production organization of the global economy and increased trade in services and intermediary goods. This new form of trade has allowed developing countries to benefit from international trade with specialization and comparative advantage in tasks, without having a ...
In this paper we consider modeling of credit risk within the Libor market models. We extend the classical definition of the defaultfree forward Libor rate to defaultable bonds with credit ratings and develop the rating based Libor market model. As driving processes for the dynamics of the default-free and the pre-default term structure of Libor rates time-inhomogeneous Lévy processes are used. ...
In a recent study we developed a fast and accurate algorithm to compute Global Positioning System (GPS) Slant Total Delay (STDs) utilizing numerical weather model data. Having developed a forward operator we construct in this study the tangent linear (adjoint) operator by application of the chain rule of differential calculus in forward (reverse) mode. Armed with these operators we show in a si...
Abstract In order to understand the real environment and specific needs of China’s current tobacco industry, master signal information in supply chain, timely discover source this paper puts forward detection method anti-counterfeiting at chain. Based on this, article constructs a nonlinear discrete system model, which mainly studies logistics existing utilizes noise chain obtained by EKF filte...
Based on the then high-tech industry policy documents issued by Beijing in 2017, this paper builds a complex network model to reflect internal structure of Beijing’s High-Technology Industry Chain (BHIC), and analyzes coevolutionary mechanisms ten top high-technology industries their detailed sectors. Especially for science technology service (S&T) industry, measures its function status sys...
