Fuzzy multiple-goal programming for analysing outsourcing cost-effectiveness in hi-tech manufacturing

Given high-tech industry trends such as limited production, diverse model range, short product life cycle, and high customer responsiveness, issues related to recognitive core vs. non-core operations in internal vs. external environments are crucial in hi-tech production systems planning. This work elucidates the relationship between capacity planning and suppliers with a focus on quantity allocation, manufacturing quantity, capacity limit, warehouse space, and time period for hi-tech production planning. A fuzzy multiple-goal programming approach is adopted to model total cost, holding cost, and rework cost in order to analyse the relative cost-effectiveness of different factors. The proposed model was examined via the fuzzy analysis of its application to an actual building-integrated photovoltaic (BIPV) manufacturer with variable characteristics. The proposed model of cost-effectiveness accommodates variables such as multiple components, quality, and responsiveness, it integrates multi-stage functions, and a specific implementation is demonstrated. Various scenarios are designed to analyse the transaction options for outsourcing under combined schemes. The analytical results in this study can help decision makers to systematically analyse the cost effectiveness of outsourcing during capacity planning in practical applications.     

A continuous-review model for dual intercontinental and domestic outsourcing

When making sourcing decisions, many firms consider only the direct and most visible supply-chain costs, such as unit production costs and ocean-shipping costs. Often ignored are the hidden direct and indirect costs in long supply chains, and their impact on profitability. As supply chains lengthen, supply-chain disruptions undercut the ability of manufacturers and retailers to satisfy market demands. Supply-chain disruptions add costs by forcing companies to increase inventories, to juggle production and shipping schedules, to incur excessive backordering, and to airfreight or discount the prices of goods that were not in the right place at the right time. The question is, can higher incidence of supply-chain disruptions in intercontinental supply chains justify keeping the domestic suppliers? To address the question, this paper presents a hybrid continuous-review inventory model for dual intercontinental and domestic outsourcing. The conditions for domestic outsourcing only, for intercontinental outsourcing, and for dual outsourcing were established. The problem of minimising the long-run average cost of outsourcing was investigated, and mathematical optimisation was used to illustrate the model. It is shown that if the cost of service failure outweighs the cost differential between domestic and intercontinental outsourcing, keeping domestic suppliers may be a good option.     

Redesigning an integrated forward–reverse logistics system for a third party service provider: an empirical study

This paper models the logistics business for a large third party service provider and incorporates both forward and reverse product flows for the company. The model that we propose in this paper incorporates price, transportation mode and outsourcing cost. We compare our model with a reduced model that was obtained from past literature and show through Monte Carlo simulation the superiority of the full model in profit generation for the third party service provider. The full model considers multiple transportation modes across the forward and reverse logistics network based on the firm's business structure, whereas the reduced model has only one transportation option from point to point. Additionally, the full model allows for an option to outsource remanufacturing unlike the reduced model that does not permit such outsourcing options. One of the major contributions of this paper is a thorough analysis through the incorporation of pricing and transportation mode of an integrated forward and reverse logistics supply chain.

既有建筑节能服务外包的激励契约设计

本文应用委托代理理论,面向既有建筑节能服务外包过程,对节能量保证型合同展开研究。建立了既有建筑业主与节能服务公司之间的利益博弈模型,并确定了最大化业主期望利润的契约参数。分析显示,在仅有道德风险情形下业主应当优先选择高能力节能服务公司,并对节能项目适当进行监督以减小不确定性。进一步地,在逆向选择与道德风险并存的情形下,高能力节能服务公司获得了信息租金,低能力节能服务公司提供的服务严格劣于帕累托最优服务,既有建筑业主可设计出一对合同实现分离均衡。理论分析结合算例得出结论:提高业主期望利润的关键在于采用具备信息甄别能力的契约、选取高能力节能服务公司、选取监督难度较小的项目,并投入适当的监督成本。

现代商业理念与“非遗”旅游开发中的难题——以大坝高装开发面临的资源成本难题为例

国家级“非遗”大坝高装的旅游开发,面临着成本高、所需资源短缺的难题,传统的小生产模式及其思想的限制是重要原因。在价值工程、外包等现代商业理念指导下整合其他“非遗”资源进行合作开发,可以较好地克服前述难题。合作开发会使“非遗”旅游开发中的各方之间的矛盾更为复杂,最佳协调方式是市场交易。但是,市场主体之间的自发交易成本过高。根据交易成本理论可找到降低成本的方式,即在政府部门主导下组建公司制经济实体作为合作开发平台,利用公司治理机制协调各利益相关者。
