Supply chain design has a crucial role in the prosperity and sustainable growth of enterprises. Network and innovation mutual relationship shapes the orientation and design of the supply chain. Networks are means of securing access to the resources, information and support. A number of studies have examined the relationship between networks and innovation, and show a positive relation between them which results in growth. The contingent nature of networking in the literature makes it a complex phenomenon for an entrepreneur to identify his/her optimal position in the web of networks and master it effectively to provide sustainable presence in the market. This paper examines different types of networking in a broad term and innovation in the context of enterprises and shows the interdependency of networking and innovation. An in-depth review of the extant literature and the grounded theory is applied to develop a conceptual framework for elements of the supply chain by exploring the major layers of networks, innovation and their mutual relationship. Based on this model, several studies are reviewed and this paper offers suggestions in order to understand how the network and innovation reciprocal relationship influences performance.

In this paper, a new mathematical model for the problem of job scheduling in virtual manufacturing cells (VMC) is presented to minimizing the completion time of all jobs. Sequence dependent setup times of machines is considered and lot-streaming is possible. In Virtual manufacturing cells, each job has a different processing path and there is a set of machines for processing each operation. There are multiple machine types with several identical machines in each type locating in different locations in the shop floor. In this type of system, the cells are not physical and Machines can be shared between the cells. In Mixed-integer nonlinear programming model presented, the scheduling decisions involve assigning a machine to each operation, the start time at each operation, the start time of machines and sub-lot sizes of each job. Some test problems have been generated to demonstrate the implementation of the model and solved by Lingo.
