    Introducing an Audit Method for Measuring the Integrity of an Organization

    , M.Sc. Thesis Sharif University of Technology Mofatteh, Mohammad Hossein (Author) ; Akbari Jokar, Mohammad Reza (Supervisor)
    Managing the supply chain is a competitive necessity in today's global marketplace where differentiation between products and services means providing a total value package that can compete for an increasingly discerning and empowered customer. Today's view is one of integration. Supply chain management is the integrated management of business links, of information flows and of people. This research is based on a study conducted to introduce a reference model for Supply Chain integration. In that study, 10 drivers are introduced as keys for integrity in Supply Chain. The objective of this article is to discuss a method which has been developed to measure objectively and quantify the level of... 

    Stable and Connected Coordination of Robotic Swarms Through Local Information

    , Ph.D. Dissertation Sharif University of Technology Etemadi Haghighi, Shahram (Author) ; Alasty, Aria (Supervisor) ; Vossoughi, Gholamreza (Supervisor)
    In this thesis, coordination of a group of autonomous agents, through a scalable control structure and with very limited communications, is addressed. Inter-agent action functions are designed to guarantee the network connectivity. Two coordinator agents with different natures are designed. One is attractive and is named leader-agent (LA). The other is repulsive and is named shepherd-agent (SA). Under the assumption that both coordinators locally affect the group, we have proved that the governing equation of the whole group may have variable order.
    By using nonlinear control techniques, coordination algorithms are designed to move the group on a predefined path or to a destination. It... 

    Two-level Robust Control of Large-scale Systems

    , Ph.D. Dissertation Sharif University of Technology Rahmani, Mehdi (Author) ; Sadati, Naser (Supervisor)
    In this thesis, two-level optimal control of uncertain and non-uncertain large-scale systems is presented. In the proposed two-level approach, using a decomposition/coordination framework, the large-scale system is first decomposed into several interactive subsystems, at the first-level, where a smaller optimization problem is solved at each subsystem. At the second-level, a substitution type prediction method, as a coordination strategy, is used to predict the interaction between subsystems. The coordinator mainly evaluates the next update for the coordination parameters and continues to exchange information with the first-level, so that the overall optimum solution is obtained. It is shown... 

    Coordination Among Nodes of a Network: an Information Theoretic

    , M.Sc. Thesis Sharif University of Technology Abroshan, Mahed (Author) ; Aminzadeh Gohari, Amin (Supervisor)
    In this work, we consider a zero error coordination problem wherein the nodes of a network exchange messages to be able to perfectly coordinate their actions with the individual observations of each other. While previous works on coordination commonly assume an asymptotically vanishing error, we assume exact, zero error coordination. Furthermore, unlike previous works that employ the empirical or strong notions of coordination, we define and use a notion of set coordination. This notion of coordination bears similarities with the empirical notion of coordination. We observe that set coordination, in its special case of two nodes with a one-way communication link is equivalent with the “Hide... 

    Coordination Investigation of Macrocyclic Ligands Tertiary Amine Groups with [60] Fullerene and Cu(II)

    , M.Sc. Thesis Sharif University of Technology Asadi Mofarrah, Leila (Author) ; Ghanbari, Bahram (Supervisor)
    The reaction of O2N2-donor naphthodiazacrown, with salicylaldehyde afforded new O3N2-donor macrocyclic ligands (L1-3naph) mounted with 1,3-diazcyclohexane subring in high yield. The product was characterized by IR, 1HNMR spectroscopy as well as elemental microanalysis and single crystal X-ray studies (just for L3naph). The interactions of [60]fullerene in presence and absence of base, Cu(II), Hg(II) and Zn(II) with L1-3naph were investigated employing fluorescence spectroscopy. The efficient fluorescence quenching of L1-3naph in presence of C60, Cu(II)( L1-2naph) and the fluorescence enhancement in presence of Hg(II) and Zn(II) indicated that the interaction with [60]fullerene Hg(II) and... 

    Optimization of Coordinated Distribution System by Adopting the Network Marketing and Traditional Channel

    , Ph.D. Dissertation Sharif University of Technology Shafiei, Mahdi (Author) ; Modarres, Mohammad (Supervisor)
    Nowadays network marketing has promoted marketing, sale and customer relationship altogether. On the other hand, due to the growth of internet, network marketing has become a powerful and attractive channel that can be utilized alongside the other traditional channel. Pricing and network marketing structure influences on distribution system coordination and networker motivation in network marketing. This thesis provides a framework to study the integration of network marketing with retailers in a dual channel distribution system and provide the pattern for determining the different variables of distribution systems, including of product price in diverse channels, commission payment to... 

    Coordination of Pricing and Production Decesions of two Substitutable Products in Multi-periods

    , M.Sc. Thesis Sharif University of Technology Hasani, Zohre (Author) ; Akbari Gokar, Mohammad Reza (Supervisor)
    This research aims to develop and propose mathematical models that can be used to facilitate cross-functional coordination between operations and marketing. The researcher has developed a dynamic model for integrating pricing and production decisions of substitutable products in order to maximize the profit of manufacturer in multi periods. The substitution is price-driven, customer-driven and both one-way and two-way directions are considered in two different models. Demand functions are linear, determined and a function of all prices. Due to the existence of substitution between products, the price elasticity is always positive and this parameter is used as a measure of substitution in...
