Tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. Production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. Hence, integration has been proposed to decide about these problems concurrently. Main problem in integration is how we can relate pro...

Supply chain management (SCM) is a subject that has found so much attention among different commercial and industrial organizations due to competing environment of products. Therefore, integration of constituent element of this chain is a great deal. This paper proposes a multi objective production-allocation and distribution planning problem (PADPP) in a multi echelon supply chain network. We ...

The significant penetration rate of wind turbines in power systems made some challenges in the operation of the systems such as large-scale power fluctuations induced by wind farms. Gas-fired plants with fast starting ability and high ramping can better handle natural uncertainties of wind power compared to other traditional plants. Therefore, the integration of electrical and natural gas syste...

This paper studies a series production system through the integration of the decisions associated with Maintenance Management (MM) and Statistical Process Control (SPC). Hence, the primary question of the paper can be stated as follows: In a series production system, how can the decisions of MM and SPC be coordinated? To this end, an integrated mathematical model of MM and SPC is developed. Usi...

Production planning of an open-pit mine is a procedure during which the rock blocks are assigned to different production periods in a way that leads to the highest net present value (NPV) subject to some operational and technical constraints. This process becomes much more complicated by incorporation of the uncertainty existing in the input parameters. The commodity price uncertainty is among ...

We use two very large datasets to obtain some of the first systematic micro evidence on how production in vertically integrated firms differs from that of unlinked producers in the same industries. The Economic Census lets us observe virtually every establishment in the private economy, and crucially, the organizational structures of the firms that own them. The Commodity Flow Survey microdata ...

determination of shipment quantity and distribution problem is an important subject in today’s business. this paper describes the inventory/distribution network design. the system addresses a class of distribution network design problem, which is characterized by multiple products family, multiple warehouses and retail-ers. the maximum capacity of vehicles and warehouses are also known. the res...

─ Advances in virtual education models have enabled us to optimize production processes, distribution and access content through the reuse of learning objects (LO), which are stored in repositories In order to improve interoperability, integration and reuse of learning objects have been defined as SCORM standards that improve the structural interoperability of learning objects. However, the lev...

A firm’s internal supply chain refers to the specific value-creating functions within the organisation, such as production, sales and distribution. Previous research has shown that these functions need to work together to achieve high levels of firm performance. However, the means to achieve this integration of internal supply chain functions have not received much attention in current literatu...
