碳排放权和其他生产投入类似，是很像大宗商品投入的生产要素。然而，参与碳交易的公司只需要在某个时间，比如一年的结尾实现碳排放权限的减量。碳排放的另一个重要特点是不可忽略的固定交易成本。本文试图揭示参与碳交易的企业应该如何优化协调其生产以及碳排放权的采购决策，以尽量减少其在长期成本。在每个阶段，该公司基于已有的排放权，波动的市场价格和库存水平决定其排放权的购买数量和生产量。我们给出了最优的联合决策结构特征: 最优排放权采购欢是状态依赖型的(s，S)型决策。生产决策基本上是状态依赖型的基库守存决策。分解的启发式计算被发现是有效的计算研究。我们解决方法是定义一类具有一类性质的二维的函数，在一个维度上定义类似K-凸函数的性质，并在另一个维度上定义类似凸函数的性质。 / The trading of emissions permits, as an effective market-based approach for emissions control, is becoming widespread over the world. Similar to any other production input, the emissions permit is a factor of production much like commodity inputs. However, a firm participating in emissions trading has only to balance its permits at the end of a time horizon, say one year. Another key feature of permit trading is the existence of non-negligible, fixed, transaction costs. This paper attempts to shed light on how such a firm should optimally coordinate its production and permit purchasing decisions in order to minimize its total cost in the long run. In each period, the firm has to decide on its permit purchase quantities and production levels based on its on-hand permit and inventory levels as well as the market-prevalent permit price. The latter evolves as a Markov process and the firm also faces random demand. We characterize the optimal joint policy structure: an optimal purchase policy is of the state-dependent (s, S) type and an optimal production decision nearly follows a state-dependent base-stock form. A heuristic based on decomposition is found to be effective from computational studies. Our enabling technique is the identification of a class of two-dimensional functions that in one dimension it looks like K-convex and in another it is similar to convex. / Detailed summary in vernacular field only. / Yuan, Quan. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 74-84). / Electronic reproduction.

Key words. Newsvendor Model, Inventory Model, Seasonal Product, Weather Risk, Weather Option, Weather Derivative, Weather-Conditional Rebate, CVaR, Mean-CVaR. / The first model considers the problem of hedging inventory risk for a newsvendor who sells a seasonal product. The newsvendor not only decides the order quantity, but also adopts a weather hedging strategy. A typical hedging strategy is to use an option that is constructed on a weather index before the season begins, which will compensate the buyer of the option if the actual seasonal weather index is above (or below) a given strike level. We explore the joint decision problem in mean-variance, expected utility, conditional value-at-risk (CVaR), and mean-CVaR frameworks. We analyze the impact of weather hedging on optimal order quantity. It is proven that the newsvendor may order more than in the absence of weather options. Numerical analysis on the sensitivity of the optimal order quantity, the risk premium of the option, the portfolio selection and the comparison between the weather option hedging and a particular operational hedging are presented as well. / The second model investigates the advantages of early sales of a seasonal product. To induce early sales, the newsvendor adopts a weather-conditional rebate program, which will pay rebates to the customers who buy the product in the preselling period if a specified weather condition for normal selling season is realized. For an example, a certain amount of refund will be paid to early buyer if the seasonal average temperature falls below the past-three-year seasonal average. Two conditional rebate programs with early booking and early purchasing are investigated and compared. Both of them can price differentiate within a customer among his/her post valuation on the seasonal product, and thus increase the sales. For the early purchasing program, it can further save inventory holding cost and ordering cost. The expected profit can be improved by the programs. Moreover, combined with weather derivatives, the conditional rebate program can manage the financial risk with the expected profit being still improved. / To investigate the means that firms may adopt in managing the adverse impacts of weather on their businesses, this dissertation proposes and analyzes two inventory models for seasonal products when the demand is sensitive to the weather in the season. Both models are formulated under the newsvendor context. / Gao, Fei. / "October 2007." / Adviser: Youhua Frank Chen. / Source: Dissertation Abstracts International, Volume: 69-08, Section: B, page: 5002. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 108-119). / Electronic reproduction.

Data are collected from twenty-nine corporations in Hong Kong, the Pearl River Delta, Beijing, and England. Concurring with the conceptual framework, competitiveness, legitimacy, and corporate social responsibility (CSR) are identified as key motivations of CEB. Among these three motivations, CSR has the most obvious direct impact on CEB. Notably, attitudes toward CSR vary significantly among corporations, and CSR is critically linked to the extent of managerial engagement in CEB. With some corporations successfully linking CEB with competitive advantage, the findings clear the causal ambiguity between engagement in CEB and competitive advantage. Several strategies in terms of reputation building, productivity improvement, market positioning, and capability enhancement are identified. The study enriches theory development of the two divergent perspectives: (a) strategic management and (b) CSR by suggesting a theory of strategic management embracing CSR in building competitive advantage, and the latter affirming engagement of CEB in improving corporate financial performance. / Existing views on how corporations resolve environmental problems are polarized with one side seeing corporate environmental investment as a cost with an inherent trade-off between economic and environmental concerns; and the other side asserting the moral obligation for corporations to do so. This study adopts a holistic view to resolve the problem by proposing a conceptual framework of corporate environmental behavior (CEB) through the linking mechanism to synthesize the seemingly diverged views. / Croft Kan, Man Ping Lena. / "December 2006." / Adviser: Shige Makino. / Source: Dissertation Abstracts International, Volume: 68-08, Section: A, page: 3457. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 257-279). / Electronic reproduction.

Environmental awareness and legislative pressures have made manufacturers responsible for the take-back and end-of-life treatment of their products. Therefore, manufacturers are struggling to find ways to recover maximum value from returned products. This goal can best be achieved by promoting multiple reuse programs as reuse is one of the most effective ways to enhance a sustainable engineering economy. Since the essential goal of the reuse strategy is to reuse parts, the reliability of used parts becomes a core issue. Research indicates that reuse is technologically feasible, associated with a significant manufacturing cost saving, and it does not compromise product quality. However, it is not easy to be applied in reality. There are several uncertainties associated with reuse, the most common is the uncertainty of the product???s quality after use. A widespread implementation of the reuse strategy could be triggered, subject to the availability of reliable methods to assess the useful remaining life of parts. The evolution of such a methodology would play a pivotal role in making decisions on the supply chain process and the recovery value of returned products. Reliability assessment by life cycle data analysis is the basis of this research. The proposed methodology addresses the problem of reliability assessment of used parts by considering two important aspects. It performs statistical as well as condition monitoring data analysis for decision-making on reuse. The analysis is carried out in two stages. Firstly, a wellknown reliability assessment procedure, the Weibull analysis, is applied to analyse time-tofailure data to assess the overall reuse potential of components. In the second stage, the used capacity (actual life) of components is determined by analysing their operating history (condition monitoring data). The linear and nonlinear regression analysis, Kriging procedures and artificial neural networks (ANN) are employed in this stage. Finally, the Weibull analysis and ANNs are integrated to estimate the remaining useful life of components/assemblies of a product at the end of its first life cycle. The model was validated by using life cycle data from consumer products.
