Although business process outsourcing (BPO) can reduce cost and enhance the competitiveness of firms, the implementation of BPO projects is unsatisfactory. By integrating knowledge management capability theory and risk-based view, we develop a model of how different types of BPO risks affect project satisfaction and how knowledge management capability changes the influences of BPO risks. A survey of 121 BPO projects was conducted among BPO client department manager and project manager through a pairwise design. Empirical evidence reveals that social system, technical system, and project management risks negatively affect BPO project satisfaction. However, cultural, technological, and structural levels of knowledge management capabilities weaken the negative risk effects of social system, technical system, and project management, respectively. Different types of risks and knowledge management capabilities should be matched to achieve effective risk management. 相似文献

This paper analyzes the model of the recycled products which are considered with the minimum quality level in manufacturing/remanufacturing system. In this model, a constant demand is satisfied by manufacturing raw materials and remanufacturing recycled products which are up to the quality level. It is assumed that functions of recycling rate, buyback cost and remanufacturing cost are depend on the minimum quality level. The quality level of recycled products is set to be exponential distribution and then the model is established. The results show that when the buyback cost is low (the quality of the recycled products is low), the average total cost is low, though the remanufacturing cost is high. Namely, the companies are willing to recycle the used products with low quality level. Meanwhile, the optimal strategy of recycling, manufacturing and remanufacturing is investigated here. Through construction of a solution process on Particle Swarm Optimization (PSO), Genetic Algorithm (GA) and numerical examples with sensitive analysis, the validity of the model has been proved. 相似文献

Emerging studies advocate that firms shall completely outsource their information security for cost and technical advantages. However, the risk of information leakage in outsourcing to managed security service providers (MSSPs) is overlooked and poses a confidentiality threat. We develop analytical models to describe several strategies for firms to consider when they decide to outsource to MSSPs. Based on our results, we suggest partial outsourcing as an alternative strategy when the firm faces information leakage risk. Besides, we suggest that in-house information security strategy is the optimal solution when the risk of being attacked is low regardless of the risk of information leakage. We then extend scenarios to the competitive environment where firms that are in the same market are highly likely to choose the same strategy. 相似文献

目的 针对低碳钢零件的破损失效采用TIG焊电弧熔覆增材制造工艺,研究低碳钢电弧熔覆修复使其达到再制造零件性能要求的可行性,为实现TIG焊修复应用提供保证。方法 通过TIG焊熔覆在低碳钢坡口处,对熔覆接头的显微组织进行分析,并测试修复后的增材层表面硬度性能。使用Nanovea Tribometer摩擦磨损仪和NanoveaPS50表面轮廓仪,对基体和增材层进行摩擦性能测试,并表征摩擦磨损后的表面形貌,探究磨损机理。采用电化学工作站对基体和增材层的腐蚀性能进行分析。结果 修复后的增材层显微硬度(220.17HV)高于基体且其摩擦性能和腐蚀性能优于基体,随着磨损载荷的增加,增材层的摩擦系数逐渐降低,磨损机制主要为磨粒磨损和粘着磨损。增材层表面组织均匀细小,在NaCl溶液中点蚀坑小且分散,增材层的腐蚀电流密度(1.8349×10-6 A/cm2)小于基体的腐蚀电流密度(6.5251×10-5 A/cm2),增材层表面的抗腐蚀能力明显提高。结论 电弧熔覆低碳钢可满足低碳钢零部件现场电弧快速修复对再制造性能的要求,实现了低碳钢破损零部件的表面修复与强化。 相似文献

The problem of designing offshore manufacturing contract resulting in optimal transfer price is troubling multinational companies over the past few years. This paper proposes designing offshore manufacturing contracts based on the transfer price in the form of bilevel programming problems after considering green tax. In these contract designs, a firm in a developed country sells a single product in its market. The same product is simultaneously being manufactured by another firm in a developing country with lower manufacturing cost. After anticipating the consumer demand, the seller places an order, based on which the manufacturer manufactures the ordered quantity, and offers a transfer price which in turn maximises its net profit after paying green tax to its government. While setting the transfer price, the manufacturer considers the manufacturing cost, the export duty payable to its government and the cost of shipping the product to the developed country. After buying the product from the manufacturer at the transfer price, the seller then sets the retail price which maximises its net profit after paying the import duty to its government; the retail price, however, must not be more than the maximum retail price applicable to the market. Thus, offshore manufacturing contract results in optimal after-tax profits for both the firms. An experimental study has been carried out to discuss the practical aspects of the results developed, where a US firm is offshoring its manufacturing activity to a Chinese firm in order to draw maximum profit. 相似文献

基于再制造和产品服务系统的特征提出了再制造产品服务系统(RPSS)的概念,根据生命周期评价(LCA)方法框架建立了RPSS LCA模型,并以柴油发动机RPSS为案例对模型开展应用研究。研究发现,确保再制造产品质量和性能不低于新品,避免产品使用过程消耗大于新品是企业通过实施RPSS获得环境效益的关键;企业开展面向再制造的产品设计,提高产品再制造率,可以降低RPSS生命周期环境影响;RPSS可以为企业提供稳定的旧件来源,提高企业市场竞争力。 相似文献
