  • the design of a jade based autonomous workflow management system for collaborative soc design
    Expert Systems With Applications, 2009
    Co-Authors: Charles V Trappey, Amy J C Trappey, Chingjen Huang
    Abstract:

    Given a fast changing electronics goods marketplace, designers of integrated circuits and components need to be more competitive, efficient, flexible, and use collaborative workflow to reduce time-to-market and a project's life cycle. In recent years, agent-based workflow management systems (WfMS) have been widely used to monitor and control business design processes. In this paper, intelligent agents are applied to the collaborative system-on-chip (SoC) design environment. The proposed JADE-based autonomous workflow management system (JAWMS) uses a workflow Coordination Mechanism and an agent integration Mechanism to enable the analysis, management and interaction of automated design processes. The workflow Coordination Mechanism uses five domain specific agents to perform the workflow enactment services and a generic agent to control the system flow logic. The system kernel of JAWMS follows the specifications of the workflow reference model provided by the workflow management coalition (WfMC). The agent integration Mechanism supports an agent to interact with other JADE-based agent platforms and to coordinate and monitor workflow Coordination messages. All agents are written in the Java language using the JADE platform and work together to perform flexible, adaptive and dynamic design tasks in an autonomous and collaborative way. JAWMS facilitates SoC design and team interaction in a collaborative but distributed product development environment.

  • a Coordination Mechanism for supplier selection and order quantity allocation with price sensitive demand and finite production rates
    International Journal of Production Economics, 2020
    Co-Authors: Jose A Ventura, Kevin A Bunn, Barbara B Venegas, Lisha Duan
    Abstract:

    Abstract We study a supplier selection and order quantity allocation problem in a two-stage supply chain, which is composed of a set of potential suppliers and a single buyer/retailer trading one product. The demand at the buyer’s stage is price-sensitive and suppliers have finite production rates. Within this framework, the optimization of the supply chain is evaluated by considering the performance of both stages and guaranteeing their profitability through a Coordination Mechanism based on profit-sharing. Two mixed integer nonlinear programming models are presented under different lot-sizing policies to determine the optimal set of selected suppliers, retail price, and order quantity and number of orders per order cycle for each selected supplier. The structure of the models’ solutions is examined by deriving properties of the optimal supplier selection and order quantity allocation scheme. Numerical examples are also provided to illustrate the applicability of the proposed models.

  • a two stage supply chain Coordination Mechanism considering price sensitive demand and quantity discounts
    European Journal of Operational Research, 2018
    Co-Authors: Barbara B Venegas, Jose A Ventura
    Abstract:

    Abstract This paper explores the Coordination between a supplier and a buyer within a decentralized supply chain, through the use of quantity discounts in a game theoretic model. Within this model, the players face inventory and pricing decisions. We propose both cooperative and non-cooperative approaches considering that the product traded experiences a price sensitive demand. In the first case, we study the dynamics of the game from the supplier's side as the leader in the negotiation obtaining a Stackelberg equilibrium, and then show how the payoff of this player could still improve from this point. In the second case, a cooperative model is formulated, where decisions are taken simultaneously, emulating a centralized firm, showing the benefits of the cooperation between the players. We further formulate a pricing game, where the buyer is allowed to set different prices to the final customer as a reaction to the supplier's discount decisions. For the latter we investigate the difference between feasibility of implementing a retail discount given a current Coordination Mechanism and without it. Finally the implications of transportation costs are analyzed in the quantity discount schedule. Our findings are illustrated with a numerical example showing the difference in the players’ payoff in each case and the optimal strategies, comparing in each case our results with existing work.

  • buyer vendor Coordination models in supply chain management
    European Journal of Operational Research, 2006
    Co-Authors: S P Sarmah, D Acharya, S K Goyal
    Abstract:

    Coordination between two different business entities is an important way to gain competitive advantage as it lowers supply chain cost. This paper reviews literature dealing with buyer vendor Coordination models that have used quantity discount as Coordination Mechanism under deterministic environment and classified the various models. An effort has also been made to identify critical issues and scope of future research. � 2005 Elsevier B.V. All rights reserved.
