A multi‐stage stochastic programming approach for network capacity expansion with multiple sources of capacity

In networks, there are often more than one sources of capacity. The capacities can be permanently or temporarily owned by the decision maker. Depending on the nature of sources, we identify the permanent capacity, spot market capacity, and contract capacity. We use a scenario tree to model the uncertainty, and build a multi‐stage stochastic integer program that can incorporate multiple sources and multiple types of capacities in a general network. We propose two solution methodologies for the problem. Firstly, we design an asymptotically convergent approximation algorithm. Secondly, we design a cutting plane algorithm based on Benders decomposition to find tight bounds for the problem. The numerical experiments show superb performance of the proposed algorithms compared with commercial software. © 2016 Wiley Periodicals, Inc. Naval Research Logistics 63: 600–614, 2017     

基于激励机制的装备采办风险总量控制

针对装备采办中的风险总量控制,提出一种激励方式来提高承包商的积极性。在单目标风险控制模型的基础上,建立了多目标风险控制模型,推导出了激励机制下风险控制的最优合同公式。对激励机制中存在的两类错误进行了理论分析和实例验证,得出了两类错误对收益的影响,并在成本控制中得到了应用,有效地提高了装备采办的质量和效率,为军方决策者在装备采办中提供了合理的参考依据。     

基于效果的装备保障合同商选择方法

基于效果的合同商装备保障是将基于效果的维修理念应用于合同商装备保障领域提出的一种装备保障策略,更加关注装备的作战效能,同时对合同商提出了更高要求,因此,选择恰当的合同商对于实现预期结果显得更为重要。而合同商选择是一个多准则决策问题,很大程度上依赖于决策者和决策条件状态的不确定性和模糊性。构建了一个基于效果的合同商选择系统流程,并提出了基于相似度的模糊TOPSIS法,简化了计算流程,最后通过一个具体案例来验证该方法的有效性。

Managing components for assemble‐to‐order products with lead‐time‐dependent pricing: The full‐shipment model

We study a component inventory planning problem in an assemble‐to‐order environment faced by many contract manufacturers in which both quick delivery and efficient management of component inventory are crucial for the manufacturers to achieve profitability in a highly competitive market. Extending a recent study in a similar problem setting by the same authors, we analyze an optimization model for determining the optimal component stocking decision for a contract manufacturer facing an uncertain future demand, where product price depends on the delivery times. In contrast to our earlier work, this paper considers the situation where the contract manufacturer needs to deliver the full order quantity in one single shipment. This delivery requirement is appropriate for many industries, such as the garment and toy industries, where the economies of scale in transportation is essential. We develop efficient solution procedures for solving this optimization problem. We use our model results to illustrate how the different model parameters affect the optimal solution. We also compare the results under this full‐shipment model with those from our earlier work that allows for multiple partial shipments. © 2007 Wiley Periodicals, Inc.

装备合同履行管理的动态演化博弈研究

在装备合同履行中存在着明显的信息不对称现象。为提高装备合同的履行效益,减少信息不对称的影响,在有限理性假设的前提下,建立了装备合同履行监督的动态演化博弈模型。对合同履行过程中承制单位与军事代表、合同履行管理部门之间的博弈关系进行了探究,得到了各参与方在不同条件下均衡策略的选择,并对优化装备合同的履行管理提出了建议。     

The impact of operational decisions on the design of salesforce incentives

When facing high levels of overstock inventories, firms often push their salesforce to work harder than usual to attract more demand, and one way to achieve that is to offer attractive incentives. However, most research on the optimal design of salesforce incentives ignores this dependency and assumes that operational decisions of production/inventory management are separable from design of salesforce incentives. We investigate this dependency in the problem of joint salesforce incentive design and inventory/production control. We develop a dynamic Principal‐Agent model with both Moral Hazard and Adverse Selection in which the principal is strategic and risk‐neutral but the agent is myopic and risk‐averse. We find the optimal joint incentive design and inventory control strategy, and demonstrate the impact of operational decisions on the design of a compensation package. The optimal strategy is characterized by a menu of inventory‐dependent salesforce compensation contracts. We show that the optimal compensation package depends highly on the operational decisions; when inventory levels are high, (a) the firm offers a more attractive contract and (b) the contract is effective in inducing the salesforce to work harder than usual. In contrast, when inventory levels are low, the firm can offer a less attractive compensation package, but still expect the salesforce to work hard enough. In addition, we show that although the inventory/production management and the design of salesforce compensation package are highly correlated, information acquisition through contract design allows the firm to implement traditional inventory control policies: a market‐based state‐dependent policy (with a constant base‐stock level when the inventory is low) that makes use of the extracted market condition from the agent is optimal. This work appears to be the first article on operations that addresses the important interplay between inventory/production control and salesforce compensation decisions in a dynamic setting. Our findings shed light on the effective integration of these two significant aspects for the successful operation of a firm. © 2014 Wiley Periodicals, Inc.

军队工程招标激励模型研究

运用激励理论研究了军队工程招标采购过程中军方与承包商之间的关系,建立了军队工程招标激励模型。在不完全信息和竞争性招标中,投标人的行为是追求最大的效用,军方则需要建立一种机制诱使投标人按真实成本信息报价,以达到预期支付最小的目的。这种招标博弈的结果是军方与投标人之间达成贝叶斯纳什均衡(Bayesian Nash equilib- rium),即军方利用激励合同诱使投标人报出其真实成本,而投标人为达到中标目的则必须采取讲真话的占优策略,最终在双方均可接受的条件下达成协议。在此基础上,结合实际研究提出了改进的综合评标模型。
