Integrated scheduling of a multi-site mining supply chain with blending, alternative routings and co-production

چکیده

This paper proposes a multi-site global optimisation model of blending operations, alternative routings and order scheduling with co-production flow. It is performed in phosphoric supply chain owning three open-pit mines different geological structures chemical compositions, each having dry plant. One main challenge the phosphate industries to produce merchantable ores (MO) that verify quality charter (chemical composition) heterogeneous source (SO). Thus, process SO followed by treatment mostly necessary obtain required MO. Six exist an MO; one them involving calcination plant generates co-product. The objective determine least costly production programme set MO orders be delivered within precise time windows, given quantities compliance specific charter, assigning for its plant, routing, blend SOs schedule; it also defines feeding plants. A real case study illustrates proposed model.

Integrated Procurement, Production and Delivery Scheduling in a Generalized three Stage Supply Chain

In this research, we investigate a three-stage supply chain with one supplier, several manufacturers and multiple retailers where the supplier provides a common raw material to each manufacturer, who in turn uses a single stage production facility to convert it into final products that are delivered at fixed lot sizes to retailers. An integrated economic procurement, production, and delivery mo...

A multi-objective evolutionary approach for integrated production-distribution planning problem in a supply chain network

Integrated production-distribution planning (PDP) is one of the most important approaches in supply chain networks. We consider a supply chain network (SCN) to consist of multi suppliers, plants, distribution centers (DCs), and retailers. A bi-objective mixed integer linear programming model for integrating production-distribution designed here aim to simultaneously minimize total net costs in ...

Optimizing of an Integrated Production-Distribution System with Probabilistic Parameters in a Multi-Level Supply Chain Network Considering the Backorder

One of the main arguments in the supply chain is integrated production-distribution planning. Integrated production and distribution of products in a supply chain plays an important role in reducing the costs of the chain. In this paper, a mathematical model for the integrated production-distribution problem in a three-level supply chain, including manufacturing plants, distribution centers and...
