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...

Supply Chain Management (SCM) plans and controls the production over a group of autonomous enterprises. Process-oriented design is used to eliminate inefficiencies of the chain on a strategic level. This Virtual Enterprise (VE) must also manage and optimize the collaborative production on a tactical and operative level. Production planning, scheduling, and control are thus important functions f...

Although the supply chain management literature is extensive, the benefits and challenges of coordinated decision making within supply chain scheduling models have not been studied. We consider a variety of scheduling, batching and delivery problems that arise in an arborescent supply chain where a supplier makes deliveries to several manufacturers, who also make deliveries to customers. The ob...

Supply chains are ubiquitous in the manufacturing of many complex products. Traditionally, supply chains have been created through the intricate interactions of human representatives of the various companies involved. However recent advances in planning, scheduling, and autonomous agent technologies have sparked an interest, both in academia and in industry, in automating the process. The Tradi...

This paper concerns the domain of Supply Chain Network Infrastructure (SCNI) usually observed in the multimodal transportation systems such as Multimodal Passenger Transport Systems supported by lines of buses, trains, etc., and focuses on the scheduling problems encountered in these systems. SCNI can be modeled as a network of lines providing cyclic routes for particular kinds of stream-like m...

In this paper, we study scheduling of several projects in supply chain environment; activities of these projects are performed by some contractor companies. We present a new practical model for solving project scheduling problem in supply chain environment. A genetic algorithm and a simulated annealing algorithm are proposed for solving our model. The elements of genetic algorithm such as gener...

This paper investigates a collaborative scheduling model in the assembly system, wherein multiple suppliers have to deliver their components to the multiple manufacturers under the operation of Supply-Hub. We first develop two different scenarios to examine the impact of Supply-Hub. One is that suppliers and manufacturers make their decisions separately, and the other is that the Supply-Hub mak...
