Abstract
Minimising time is a key factor in ensuring speedy results leading to customer satisfaction. In the case of e-waste, the CReW concept proposed the addition of maker-spaces for e-waste dis-assembly, segregation and initial repairs and maintenance. Innovations are also expected to be undertaken here to create new products. For these, customers should not have to wait long and thus this work explores queueing theory as an Operations Research method to ensure a lean supply chain with satisfied customers.
