@RISK 5.0.1 更新
2008-09-25  广州博脉
@RISK 5.0.1 是对 @RISK 5.0 的一个维护更新。所有目前还在维护计划中的 @RISK 5.0 用户都可以享有这个更新。
w_ww.p__o_m_i_n__e_._com
请注意:
所有 DecisionTools Suite 5.0 已经包含 @RISK 5.0.1,并不需要更新。这个更新不能在 5.0 之前的版本上起效,你必须拥有 @RISK 5.0 来使用这个更新。
w_ww__.__pomin__e__.c_om_
@RISK 5.0.1 增加了以下内容:
w_ww.__p_o__m_in__e._c_o_m_
Fit Distributions to Simulation Results
w_ww.p_om_i_n_e_.com_
A new button has been added to the @RISK graph window that, in a single click, specifies the distribution function with best fits your simulated results.

Disable Smart Sensitivity Analysis
w_ww__._po__m__i_n__e._co_m_
Smart Sensitivity Analysis in @RISK 5.0 pre-screens inputs based on their precedence in formulas to outputs. Inputs, located in formulas, that have no link via your model's formulas to an output are removed from sensitivity analysis, thus avoiding erroneous results.
ww_w_.__po_mi__n_e_.c__o__m_
In @RISK 5.0.1 you can disable Smart Sensitivity Analysis in Application Settings, making Sensitivity Analysis like it was in @RISK 4.5.
w__w_w_.p_o_m_i_n_e_.__c__o_m__
There are isolated instances where you should disable Smart Sensitivity Analysis to improve performance and sensitivity analysis results:
w_w_w._p_o__mi__ne._com__
The Smart Sensitivity Analysis setup time for scanning precedents at the start of the simulation adds to runtime of very large models and you are not concerned that you may see sensitivity analysis results (or tornado graph bars) for inputs unrelated to outputs.
You use a macro or DLL that performs calculations using @RISK input values in cells that have no relationship via workbook formulas with the output. This macro or DLL then returns a result to a cell that is used in calculating the outputs value. In this case there is no relationship in workbook formulas between the output and the @RISK distributions and Smart Sensitivity Analysis should be disabled. To avoid situations like this, we recommend that you create macro functions (UDFs) that explicitly reference all used input cells in their argument lists.

Support for @RISK 4.5 Macros
w__w_w_.__po__m__i__n__e_.__com
@RISK 5.0.1 provides backward compatibility with commonly-used @RISK 4.5 VBA macro commands via new macro wrappers. @RISK 4.5 macros using Simulation Settings and Run Simulation commands will run in @RISK 5.0.1.
ww__w.__p_o_m_i_n_e__._c_o_m__
RISKOptimizer Speedup
w__ww_.p_om_i__n_e._co_m__
The Industrial edition of @RISK 5.0.1 includes RISKOptimizer 5.0.1, which runs up to four times faster than RISKOptimizer 5.0.0.
