Generating Pareto‐optimal boundary points in multiparty negotiations using constraint proposal method

In this paper a constraint proposal method is developed for computing Pareto‐optimal solutions in multiparty negotiations over continuous issues. Constraint proposal methods have been previously studied in a case where the decision set is unconstrained. Here we extend the method to situations with a constrained decision set. In the method the computation of the Pareto‐optimal solutions is decentralized so that the DMs do not have to know each others' value functions. During the procedure they have to indicate their optimal solutions on different sets of linear constraints. When the optimal solutions coincide, the common optimum is a candidate for a Pareto‐optimal point. The constraint proposal method can be used to generate either one Pareto‐optimal solution dominating the status quo solution or several Pareto‐optimal solutions. In latter case a distributive negotiation among the efficient points can be carried out afterwards. © 2001 John Wiley & Sons, Inc. Naval Research Logistics 48: 210–225, 2001

去调频处理中空变相位误差补偿方法

调频连续波具有较长的脉宽和较大的信号带宽,通常采用去调频的处理方式,但是,去调频的处理会引入空变的相位误差。从去调频的处理方式入手,根据发射信号相位误差缓变的特点,提出了依据发射信号相位误差模型补偿空变相位误差的方法,并在理论上对该方法进行了推导。该补偿方法分为两步,从差频信号中去除发射信号相位误差,在残余视频相位误差校正之后,通过与补偿函数相乘去除剩余的相位误差。仿真和实测的实验结果表明,该方法能够克服目标距离的限制,有效地补偿空变相位误差带来的影响,提高脉压水平。提出的误差补偿方法能够很好地平衡系统负载、误差补偿精度和算法开销,具有较强实用性。     

Effectiveness of (R,Q) policies in one‐warehouse multiretailer systems with deterministic demand and backlogging

Consider a distribution system with a central warehouse and multiple retailers. Customer demand arrives at each of the retailers continuously at a constant rate. The retailers replenish their inventories from the warehouse which in turn orders from an outside supplier with unlimited stock. There are economies of scale in replenishing the inventories at both the warehouse and the retail level. Stockouts at the retailers are backlogged. The system incurs holding and backorder costs. The objective is to minimize the long‐run average total cost in the system. This paper studies the cost effectiveness of (R, Q) policies in the above system. Under an (R, Q) policy, each facility orders a fixed quantity Q from its supplier every time its inventory position reaches a reorder point R. It is shown that (R, Q) policies are at least 76% effective. Numerical examples are provided to further illustrate the cost effectiveness of (R, Q) policies. © 2000 John Wiley & Sons, Inc.
