The importance of drug as a valuable export product in the global economy becomes more clear every day. Understanding the problems of exports and factors affecting it, can be an important step to keep Iran’s position in the world markets and further export development of this product.In this study, Iranian pharmaceutical exports’ supply and demand functions were calculated using co-integration ...

The European seed business of Syngenta relies on its supply chain to supply seed products to the different European markets, which led to more than 1.2 billion USD revenues in 2013. The seed supply chain is, however, exposed to a high level of uncertainty – from the demand side as well as from the supply side. Determining optimal production volumes in a highly volatile environment and more than...

on time supply of materials in construction projects is very important. therefore, coordinating a project with key suppliers, while ensuring the timely supply of materials, make the minimum costs of project. one way to create this coordination is integrated inventory planning which has been accomplished in this study. it is necessary to mention that such a model is considered np_hard in terms o...

This work develops a fuzzy linear programming (FLP) method for solving the transportation planning decision (TPD) problems with fuzzy goals, available supply and forecast demand. The proposed method attempts to minimize the total production and transportation costs and the total delivery time with reference to available supply and machine capacities at each source, as well as forecast demand an...

Ensuring water availability for multiple needs represents a sustainable development challenge globally. Rigid planning for fixed water supply and reuse targets with estimated demand growth and static assumptions of water availability can prove inflexible in responding to changing conditions. Formal methods to adaptively respond to these challenges are needed, particularly in regions with limite...

We study the strategic design of a supply chain for new products. Planning a supply chain for a new product requires addressing both uncertainties in demand and cost and changes in market conditions over time. We develop a mathematical programming model for new products that includes both financial viability and robustness relative to uncertainty. An example based on a Fortune 200 company’s eff...

A key element to a company’s success is its ability to match its supply to uncertain demand by utilizing different types of capacity contracts. We consider the design of a multi-product supply chain, for which each product requires one or more process capabilities and each process can get capacity from multiple resources. We present a single-period model to determine the capacity investments fo...

This paper aims to examine integration of supply chain and demand chain in emerging markets. We present a research model of demand and supply chain integration which responds to customer’s needs through the integrated information flows. Integration of demand and supply chain synchronizes the key processes in terms of frontend development, product planning, product design, procurement, manufactu...

In this work we propose a stochastic model for the design and planning of closed-loop supply chains. Uncertainties in demand and return volumes are modelled together with uncertain transportation costs. A two-stage stochastic programming is developed and a sensitivity analysis to the worst-case probability is performed in order to test the solution robustness. Finally, in order to prove the goo...

Within inter-organizational supply chains decentralized planning spheres lead to new challenges for the tracking and tracing of the fulfillment process. Nevertheless, information about progress and delays for instance in production has to be gathered to plan and to control the supply chain activities. Due to decentralized planning there is a lack of central information about structure and sched...
