问题描述
我正在 flex（一种医院预约系统）中做一个小培训项目。我似乎无法将准入类型输出到控制台； （住院病人、门诊病人、日间病人、候补名单），根据规则。它只返回“否”，它应该返回“住院病人”、“日间病人”、“门诊病人”或“候补名单”，其他人能看到我遗漏了什么吗？它把我逼上墙...

%ACTION---------------------------
action create ; %This action is to create
do ask subject
and ask patient_risk
and ask condition_time
and ask clinical_trial
and ask antibody_count
and ask life_style
and ask anaemia_state
and ask blood_pressure
and check that Patient1 is subject
and subject is a new patient whose patient_risk is patient_risk
and whose condition is patient_condition
and whose lifestyle is life_style
and whose anaemia is anaemia_state
and invoke ruleset testing
and restart. %resets collected data
%ACTION---------------------------
%consider rulesets instead for admission types.
rule clinical_trial_not_ok
if patient_risk is high
then clinical_trial becomes no
and admission becomes daypatient
and write ( 'the recommended admission is ' )
and write ( admission ).
rule condition_months
if patient_risk is included in ( low,medium )
and condition_time is months
then antibody_count becomes high
and admission becomes daypatient
and write ( 'the recommended admission is ' )
and write ( admission ).
rule condition_days
if condition_time is days
then antibody_count becomes low
and admission becomes outpatient
and write ( 'the recommended admission is ' )
and write ( admission ).
rule active_not_anaemic
if patient_risk is included in ( low,medium )
and condition_time is weeks
and life_style is active
and anaemia_state is no
then admission becomes outpatient
and write ( 'the recommended admission is ' )
and write ( admission ).
rule sedentary_highblood_anaemic
if patient_risk is included in ( low,medium )
and life_style is sedentary
and anaemia_state is yes
and blood_pressure is yes
then admission becomes inpatient

rule active_and_anaemic

and write ( admission ).
ruleset testing
contains all rules ;
select rule by first come first served.
frame patient ; %frame for base values of patients.
and default patient_risk is none %sets the risk to 'none'
and default condition_time is none
and default clinical_trial is none
and default antibody_count is none
and default life_style is none
and default anaemia_state is none
它应该通过提出问题并从问题中收集数据以满足规则来工作；当它们符合准入类型的条件时，在控制台上显示该准入。
-
如果抗体计数中等， 和久坐不动的生活方式， 并且临床试验是合理的， 并且存在贫血， 并且血压升高， 那么推荐的入院是住院。
-
如果抗体计数低， 或（没有贫血， 并且生活方式活跃）， 那么推荐的入院是门诊。
-
如果抗体计数很高， 或临床试验不合理， 那么推荐的入院是日间病人。
如果推荐入院不是住院， 并且推荐的入院不是门诊， 并且推荐的入院不是日间病人， 那么推荐的入场是等待名单。
