Capacity and Backlog Management in Queuing-based Supply Chains
نویسندگان
چکیده
In this paper, we model and analyze a type of two-stage serial supply chain often found in service sector and maketo-order manufacturing industries. The chain holds no finished goods inventory at either stage. Rather, processing occurs only after an order is received and backlogs are managed solely by adjusting capacity. We model this supply chain using a tandem queuing model. Our analysis considers the impact of changes in first stage lead-time and capacity adjustment time on backlog, waiting time, and capacity variances at both stages. The results can be used to support the argument for better coordination across stages in these types of supply chains.

Capacity and Backlog Management in Service-Oriented Supply Chains
We investigate the dynamic behavior of service-oriented supply chains by developing a two-stage serial capacity management model. Reflecting the reality of many service (and custom manufacturing) supply chains, each stage holds no finished goods inventory, but rather only backlogs that can be managed solely by adjusting capacity. Using control theory, we develop an optimal policy that trades of...
متن کاملThe impact of freight transport capacity limitations on supply chain dynamics
We investigate how capacity limitations in the transportation system affect the dynamic behaviour of supply chains. We are interested in the more recently defined, ‘backlash’ effect. Using a system dynamics simulation approach, we replicate the well known Beer Game supply chain for different transport capacity management scenarios. The results indicate that transport capacity limitations negati...
متن کاملRobust supply chain coordination modeling: A revenue management perspective
The revenue management concept and techniques are applied to model the coordination of supply chain elements. The fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. The output of the supply chain can be various products and thus it is measured in terms of ...
متن کاملA queuing-location model for in multi-product supply chain with lead time under uncertainty
Supply chain network design (SCND) problem has recently been gaining attention because an integrated management of the supply chain (SC) can reduce the unexpected/undesirable events and can affect definitely the efficiency of all the chain. A critical component of the planning activities of a manufacturing firm is the efficient design of its SC. Hence, SCND affords a sensitive platform for effi...
متن کاملThe optimal warehouse capacity: A queuing-based fuzzy programming approach
Among the various existing models for the warehousing management, the simultaneous use of private and public warehouses is as the most well-known one. The purpose of this article is to develop a queuing theory-based model for determining the optimal capacity of private warehouse in order to minimize the total corresponding costs. In the proposed model, the available space and budget to create a...
