This contribution describes a general mixed-integer linear programming model based on a time-indexed formulation covering the relevant features required for the complete supply chain management of a multi-site production network. While the actual application is taken from the chemical industry, the model provides a starting point for many applications in the chemical process industry, food or c...

in this study, a new stochastic model is proposed to deal with a multi-product, multi-period, multi-stage, multi-site production and transportation supply chain planning problem under demand uncertainty. a two-stage stochastic linear programming approach is used to maximize the expected profit. decisions such as the production amount, the inventory level of finished and semi-finished product, t...

We developed a strategic-planning model to optimize BMW’s allocation of various products to global production sites over a 12-year planning horizon. It includes the supply of materials as well as the distribution of finished cars to the global markets. It determines the investments needed in the three production departments, body assembly, paint shop, and final assembly, for every site and the ...

For the practical use of supply chain management powerful planning tools are needed to support production and logistics decisions at various planning levels. In our paper, we focus on medium-term supply network planning. As a real application, the production of a chemical additive in a multi-site production and distribution network is considered. Supply network planning is an exceedingly comple...

We address in this paper the optimization of a multi-site, multi-period, and multi-product planning problem with sequence-dependent changeovers, which is modeled as a mixedinteger linear programming (MILP) problem. Industrial instances of this problem require the planning of a number of production and distribution sites over a time span of several months. Temporal and spatial Lagrangean decompo...

Due to the progress of high technology, TFT-LCD (Thin Film Transistor – Liquid Crystal Display) has been widely put in use recently. The manufacturing technology of the TFT-LCD industry mainly consists of array, cell, module processes, in which there exists special characteristics such as different objectives of individual process’s scheduling, complexity of manufacturing processes, and multi-s...

in iran the mainstreaming tool for integrating environmental concerns into energy sector is an energy-environment review (eer-iran). this paper comprises: (i) an analysis of the current situation with regards to energy production and consumption; (ii) an evaluation of the growth prospects with regard to energy production and consumption; (iii) the identification of environmental issues induced ...

We investigate tactical level planning problems in float glass manufacturing. Float glass manufacturing is a process that has some unique properties such as uninterruptible production, random yields, partially controllable co-production compositions, complex relationships in sequencing of products, and substitutable products. Furthermore, changeover times and costs are very high, and production...

hazards in different areas have different effects and consequences. nowadays considering industries vital conditions, it seems necessary to boost organizations confronting uncertainties and risks. one solution for reducing these risks, is increasing agility, stability and flexibility in production process. this study tries to increase organization capabilities in supply chain hazards handing, u...
