空袭兵器作战效能标准化问题研究

空袭兵器作战效能标准化将典型的空袭兵器的作战效能指数向选定的标准空袭兵器转化,其转化的结果用于防空兵力需求的计算。标准化过程主要包括标准空袭兵器的选择、作战效能指标体系的建立、指标权重的计算、性能指标参数的归一、效能指数的解算和标准化系数的换算六个步骤,运用加权算法、幂指数法和层次分析法建模计算,最终得出美台主要空袭兵器标准化效能数据。为空袭兵器作战效能的标准化提供了一种科学方法,从而便于实施防空作战资源需求分析和防空作战资源作战效能分析。

Supply chain coordination with product line design and a revenue sharing scheme

Many manufacturers sell their products through retailers and share the revenue with those retailers. Given this phenomenon, we build a stylized model to investigate the role of revenue sharing schemes in supply chain coordination and product variety decisions. In our model, a monopolistic manufacturer serves two segments of consumers, which are distinguished by their willingness to pay for quality. In the scenario with exogenous revenue sharing ratios, when the potential gain from serving the low segment is substantial (e.g., the low‐segment consumers' willingness to pay is high enough or the low segment takes a large enough proportion of the market), the retailer is better off abandoning the revenue sharing scheme. Moreover, when the potential gain from serving the low (high) segment is substantial enough, the manufacturer finds it profitable to offer a single product. Furthermore, when revenue sharing ratios are endogenous, we divide our analysis into two cases, depending on the methods of cooperation. When revenue sharing ratios are negotiated at the very beginning, the decentralized supply chain causes further distortion. This suggests that the central premise of revenue sharing—the coordination of supply chains—may be undermined if supply chain parties meticulously bargain over it.     

Single‐machine scheduling with deadlines to minimize the total weighted late work

We consider scheduling a set of jobs with deadlines to minimize the total weighted late work on a single machine, where the late work of a job is the amount of processing of the job that is scheduled after its due date and before its deadline. This is the first study on scheduling with the late work criterion under the deadline restriction. In this paper, we show that (i) the problem is unary NP‐hard even if all the jobs have a unit weight, (ii) the problem is binary NP‐hard and admits a pseudo‐polynomial‐time algorithm and a fully polynomial‐time approximation scheme if all the jobs have a common due date, and (iii) some special cases of the problem are polynomially solvable.
