项目型供应链管理模式能有效实现装备研制过程中行为主体间的优势互补和资源的优化配置,利于供应链整体效益的提高,但各种不确定性因素会导致主体间风险传递行为的发生。为提供风险控制有效对策,通过考虑节点位置重要度和属性重要度,构建了项目型供应链节点重要度评估模型;通过衡量行为主体风险识别和风险控制的努力程度,给出了行为主体抗风险努力程度的评价方法,最后提出了一种基于节点重要度和抗风险努力程度的项目型供应链利益分配策略,该策略能有效促使行为主体主动进行风险识别和风险控制,是一种"风险共担、利益共享"的项目型供应链合作博弈策略。

基于险度函数的装备供应链库存风险损失度量

目前,对供应链库存风险损失的定量研究比较少,而定量研究中鲜有对风险偏好变化问题的研究,因此首先分析了各种风险度量方法,通过比较采用了险度函数作为对装备供应链风险损失的度量方法;然后,结合装备供应链实际,提出了定常风险偏好特性险度函数和可变风险偏好特性险度函数的适用范围,以及装备供应链库存风险损失度量的损失水平值,并给出了装备供应链库存风险损失度量函数;最后,通过算例进行了验证.实验结果表明:行为人的不同风险偏好特性会对同一事态产生不同的预判,进而可能影响对风险的决策,这是符合客观现实的.

装备采购线性合同优化研究

高额装备费支出使对招投标合同优化问题备受国防经济学界关注,对装备采办过程中招投标线性合同的优化进行了研究。采用招投标模型与委托-代理模型分析相结合的方法,先从道德风险与风险分担2个方面分析装备采购合同的优化问题,然后引入竞争效应,分析风险分担的问题。即使在双方为风险中性不需要风险分担时,DoD仍然需要在最初的投标竞争与中标后承包商降低成本行为之间进行权衡。一般的投标中,应使最终支付基于实际成本和投标值2个因素,并考虑最终支付基于道德风险损失。研究的基本结论是:固定价格合同应尽可能少地使用;若存在2个以上的投标人,成本加价合同也应禁止使用;在使用激励合同时,应慎重选择合同系数,提出了计算优化线性激励合同系数的方法。

A supply chain design model with unreliable supply

Uncertainties abound within a supply chain and have big impacts on its performance. We propose an integrated model for a three‐tiered supply chain network with one supplier, one or more facilities and retailers. This model takes into consideration the unreliable aspects of a supply chain. The properties of the optimal solution to the model are analyzed to reveal the impacts of supply uncertainty on supply chain design decisions. We also propose a general solution algorithm for this model. Computational experience is presented and discussed. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

Outbound supply chain network design with mode selection and lead time considerations

We present a large‐scale network design model for the outbound supply chain of an automotive company that considers transportation mode selection (road vs. rail) and explicitly models the relationship between lead times and the volume of flow through the nodes of the network. We formulate the problem as a nonlinear zero‐one integer program, reformulate it to obtain a linear integer model, and develop a Lagrangian heuristic for its solution that gives near‐optimal results in reasonable time. We also present scenario analyses that examine the behavior of the supply chain under different parameter settings and the performance of the solution procedures under different experimental conditions. © 2006 Wiley Periodicals, Inc.

Benders decomposition with alternative multiple cuts for a multi‐product closed‐loop supply chain network design model

In this article, we consider a multi‐product closed‐loop supply chain network design problem where we locate collection centers and remanufacturing facilities while coordinating the forward and reverse flows in the network so as to minimize the processing, transportation, and fixed location costs. The problem of interest is motivated by the practice of an original equipment manufacturer in the automotive industry that provides service parts for vehicle maintenance and repair. We provide an effective problem formulation that is amenable to efficient Benders reformulation and an exact solution approach. More specifically, we develop an efficient dual solution approach to generate strong Benders cuts, and, in addition to the classical single Benders cut approach, we propose three different approaches for adding multiple Benders cuts. These cuts are obtained via dual problem disaggregation based either on the forward and reverse flows, or the products, or both. We present computational results which illustrate the superior performance of the proposed solution methodology with multiple Benders cuts in comparison to the branch‐and‐cut approach as well as the traditional Benders decomposition approach with a single cut. In particular, we observe that the use of multiple Benders cuts generates stronger lower bounds and promotes faster convergence to optimality. We also observe that if the model parameters are such that the different costs are not balanced, but, rather, are biased towards one of the major cost categories (processing, transportation or fixed location costs), the time required to obtain the optimal solution decreases considerably when using the proposed solution methodology as well as the branch‐and‐cut approach. © 2007 Wiley Periodicals, Inc.

A linear programming model for design of communications networks with time varying probabilistic demands

In this paper marginal investment costs are assumed known for two kinds of equipment stocks employed to supply telecommunications services: trunks and switching facilities. A network hierarchy is defined which includes important cases occurring in the field and also appearing in the literature. A different use of the classical concept of the marginal capacity of an additional trunk at prescribed blocking probability leads to a linear programming supply model which can be used to compute the sizes of all the high usage trunk groups. The sizes of the remaining trunk groups are approximated by the linear programming models, but can be determined more accurately by alternate methods once all high usage group sizes are computed. The approach applies to larger scale networks than previously reported in the literature and permits direct application of the duality theory of linear programming and its sensitivity analyses to the study and design of switched probabilistic communications networks with multiple busy hours during the day. Numerical results are presented for two examples based on field data, one of which having been designed by the multi-hour engineering method.     

A facility reliability problem: Formulation,properties, and algorithm

Having a robustly designed supply chain network is one of the most effective ways to hedge against network disruptions because contingency plans in the event of a disruption are often significantly limited. In this article, we study the facility reliability problem: how to design a reliable supply chain network in the presence of random facility disruptions with the option of hardening selected facilities. We consider a facility location problem incorporating two types of facilities, one that is unreliable and another that is reliable (which is not subject to disruption, but is more expensive). We formulate this as a mixed integer programming model and develop a Lagrangian Relaxation‐based solution algorithm. We derive structural properties of the problem and show that for some values of the disruption probability, the problem reduces to the classical uncapacitated fixed charge location problem. In addition, we show that the proposed solution algorithm is not only capable of solving large‐scale problems, but is also computationally effective. © 2009 Wiley Periodicals, Inc.
