刍议环境投资决策的基本方法

环境管理会计是将环境因素引入管理会计体系的正在形成之中的新兴管理会计学分支.在环境因素逐渐成为影响企业活动的重要因素的背景下,环境管理会计以其适应企业现实的经营状况等优势,日渐受到企业的重视,同时其理论的发展也在不断的完善之中.环境投资决策就是将环境因素引进管理会计之中,在管理会计进行各种决策分析时,通过确认,计量各种由于环境因素所造成的收益与成本,并将其纳入到管理会计分析的模型之中.其中着重介绍了环境投资决策的基本方法,并举实例对环境项目的决策进行分析.     

再论建设项目的投资控制

合理确定建设项目投资控制的目标，做好决策阶段、设计阶段的投资控制以及主动控制各阶段对建设项目的投资控制均具有十分重要的作用，此外，还必须加强技术与经济的相结合，正确处理好二者之间的关系，这样才能切实地将控制项目投资概念渗透到各项工作中去。

The Special Purpose Dexterous Manipulator (SPDM) Systems Engineering Effort – A successful exercise in cheaper,faster and (hopefully) better systems engineering

The Special Purpose Dexterous Manipulator (SPDM) is the latest Space Robot developed by the Canadian Space Agency (CSA) and McDonald Detwiller Space and Advanced Robotics (MD Robotics, previously Spar Aerospace) for the International Space Station (ISS). The SPDM has presented its designers with a number of new challenges in performing the Systems Engineering effort required for a complex robotic system:(1) The SPDM initial design was started and attained various levels of maturity for various components under the Space Station Freedom environment, then the Program was stopped and finally restarted under the harsher environment in which the International Space Station is being built.(2) The SPDM is the first space robot to utilize previously developed and space certified robotic components, as well as components with high-commonality to the previously developed ones (electronics, S/W).(3) New requirements levied by the Customer during the negotiations leading to the Program re-start necessitated significant architectural changes versus the SPDM configuration `frozen' when the Program was shut down.(4) The SPDM is the first robotic system of this complexity that is being built under a Firm Fixed Price contract, with the commonality assumptions as one of the cost drivers.This combination of components of various pedigree, coupled with the constraints imposed by an FFP contract have been addressed by the designers through the definition of a novel approach to integrated Systems and Design Engineering.
