mathematical modeling of supply chain operations has proven to be one of the most complex tasks in the field of operations management and operations research. despite the abundance of several modeling proposals in the literature; for vast majority of them, no effective universal application is conceived. this issue renders the proposed mathematical models inapplicable due largely to the fact th...

totoday’s market place is increasingly dynamic and volatile. in this area supply network issues recently have attracted a lot of attention from industrial practitioners and academics worldwide. chaos theory is the study of complex, nonlinear, dynamic systems. for chaotic systems, a tiny change in conditions may result in an enormous change in system output, whereas substantial changes in condit...

Implementation of a supply-chain (SC) system has crucial impacts on a company's financial performance. Overall performance of a SC network is influenced significantly by the decisions taken in its production-distribution plan which integrates the decisions in production, transport and warehousing as well as inventory management. Thus, one key issue in the current research area of performance ev...

Smart Thermal Grids (STG) represents a new concept in the energy sector that involves the use of the smart grid concept in heat grids connecting several parties to each other via bidirectional transport of heat. The focus of this paper is on modeling and control of STGs in which the uncertainties in the demand and/or supply are included. To this end, we use Model Predictive Control (MPC), which...

This paper presents a competitive supply chain network design problem in which one, two, or three supply chains are planning to enter the price-dependent markets simultaneously in uncertain environments and decide to set the prices and shape their networks. The chains produce competitive products either identical or highly substitutable. Fuzzy multi-level mixed integer programming is used to mo...

Abstract To achieve high efficiency in supply chain network, an orderly and flexible flow of materials is essential. In this paper we develop a practical mixed integer programming model for a supply chain network design problem where the objective is to minimize the total production, transportation and distribution costs and the fixed costs for opening warehouses. We employ Lagrangian relaxatio...

The supply chain of agricultural products has received a great deal of attention lately due to issues related to public health. Something that has become apparent is that in the near future the design and operation of agricultural supply chains will be subject to more stringent regulations and closer monitoring, in particular those for products destined for human consumption (agri-foods). This ...

We present a novel simulation platform called Optimization, Simulation, and Forecasting (OSF) for the domain of manufacturing and logistics supply-chain systems. It supports composition of DEVS, Linear Program (LP), and forecast models using an extended Knowledge Interchange Broker (KIB). Models developed in DEVS-Suite simulator, OPL-Studio optimization, and a heuristic Inventory Strategy Forec...
