The supply chain of a manufacturing enterprise is a world-wide network of suppliers, factories, warehouses, distribution centres and retailers through which raw materials are acquired, transformed and delivered to customers. Supply chain management is the strategic, tactical and operational level decision making that optimizes supply chain performance. The strategic level defines the supply cha...

This study aims to discuss the solution methodology for a closed-loop supply chain (CLSC) network that includes the collection of used products as well as distribution of the new products. This supply chain is presented on behalf of the problems that can be solved by the proposed meta-heuristic algorithms. A mathematical model is designed for a CLSC that involves three objective functions of ma...

In this paper, developed a new multi-product, multi-period, and multi-level closed-loop green supply chain planning model under uncertain conditions. The formulated model consists of five objective functions, which minimize the cost of the supply chain, minimize the CO2 emission of transportation vehicles, maximize the reliability of manufacturing and distribution centers, maximize t...

In this paper, we consider discrete time dissipativeness on quadratic difference forms and two-variable dipolynomial matrices. We show that if a system is dissipativeness for a supply rate on the dipolynomial ring, then there also exist storage functions and dissipation rates on the dipolynomial ring. Moreover, we clarify whether extremal storage functions for a given supply rates on the dipoly...

In this study a supply chain network design model has been developed considering both forward and reverse flows through the supply chain. Total Cost, environmental factors such as CO2 emission, and social factors such as employment and fairness in providing job opportunities are considered in three separate objective functions. The model seeks to optimize the facility location proble...

In this paper we present a version of the balancing technique for nonlinear systems which are dissipative with respect to a general quadratic supply rate that depends on the input and the output of the system. We discuss an input output approach that allows us to apply the theory of balancing based upon Hankel singular value analysis. In order to do that we prove that the available storage and ...

Abstract The problem of input-to-state stability (ISS) and its integral version (iISS) are considered for switched nonlinear systems with inputs, resets possibly unstable subsystems. For the dissipation inequalities associated Lyapunov function each subsystem, it is assumed that supply functions, which characterize decay rate ISS/iISS gains subsystems, nonlinear. change in value functions at sw...

This Essay considers the substantive and institutional aspects of an economic theory of contract regulation. It lists the various functions that analysts have assigned to contract regulation and briefly discusses the substantive wisdom and institutional feasibility of performing those functions. The essay tentatively concludes that the state should enforce contracts, supply vocabularies that ar...

The Analysis of power supply noise on VLSI chips is becoming important. In this paper we propose a new methodology for the estimation of power supply noise, caused by digital switching activity. Using transfer function calculated hierarchically from Fmatrices, this method makes it possible with dramatically reduced computational cost to estimate power supply noise at all the nodes in power supp...
