In this paper we present an approximate analysis of fork/join prim-itives with two parallel servers, limited buuers and non-zero join times where either jobs arrive according to a Poisson process (open system) or the number of jobs is limited according to the CONWIP rule (closed system). The approximation method is based on the concept of ow-equivalent servers and enables the approximate analys...

To operate a multiple product manufacturing system under a CONWIP control policy, one must decide how to assign kanbans to products. With a fixed total number of kanbans in a competitive environment, the goal is to determine their allocation to product types in order to minimize lost sales equitably. In particular, we consider systems in which the products may make multiple visits to the same s...

In this paper, the focus is on the dynamic control card in a conwip system. An approach to set the number of cards in order to adapt to the change of the production systems both in terms of external change as the demand and internal change as the work time of the machine, failures and so on. A Multi Agent Architecture is proposed to implement a flexible and extensible approach that can be imple...
