简介:能力获得和定价决定是一公司长期的战略决定。然而,多重产品的需求无常和substitutability引起困难解决能力和定价决定问题。在这份报纸,我们与需求无常和比赛探讨一个多重产品定价和多重资源能力获得问题。在要求前为每个资源和产品价格决定能力承诺的公司需要被认识到以便全部的利润被最大化。如果需求超过承诺的能力,额外的数量能从点市场被购买。费用被考虑的可变单位生产费用,能力获得和维护。我们首先分析一个单个公司基本问题并且在价格和能力上发现最佳的答案。基于单个公司模型,我们探讨越过产品并且越过公司价格比赛因素考虑的二产品的、二公司的能力承诺和定价问题。价格和能力承诺上的平衡的存在和唯一被证明,然后我们延长了结果到多重产品,多重公司大小写。
简介:倾倒区域能力被水动力学过程主要影响(潮汐的沉积,暴风雨巨浪和波浪,等等)象倾倒区域的尺寸和深度一样。在作为FVCOM(有限体积海岸和海洋模型)知道的三维的海洋发行量模型和随机的动态统计分析模型上基于,利用倾倒地面地形学进化并且倾倒数量,讨论水动力学过程和倾倒的活动的影响的作者目的以便造了倾倒区域能力的海洋的一个新模型。与在倾倒的区域的深度和倾倒的数量的数据,底部的变化地志它基于FVCOM水动力学和沉积模块在自然条件下面由潮汐的电流引起了,为倾倒分析变化的统计关系的作者努力总计,潮汐的电流和底部地志。通过到合适的修订系数值,它将被认为是地志的真实数据改变引用波浪和暴风雨影响的价值澎湃。因此在倾倒的能力作为长期的变化拿这评估。在建立底部的阀值的前提地志的变化,倾倒的区域能力被计算。每年拿Yangtze河口号码1作为一个例子倾倒区域,作为由0.5m的水深度还原剂,倾倒的区域能力是模型结果在对实际数量的合理同意的大约670万m3/a,。然后,模型在海湾倾倒区域,Shengsishangchuan山倾倒区域,Dongding倾倒区域,Dongshan倾倒区域,和Wenzhou移植倾倒区域的Luoyuan被验证,它在外面是拐弯结果类似于实际观察的。
