自己整理了一下思路,才发现自带的代码是多么的精简,这就是高手与新手的差别啊~~
! ?, o4 l5 C) Y& c% d# V以下是我按照自己的思路编写的代码:- int batchnumber = 5;' ~* h0 a8 I6 G& k% q- N
- double cycletime = exponential(0, 4, 0);
: F1 T0 B% k g/ P5 F, R. M - string labelName = "批次数量";! g" i/ Q4 J8 i+ m/ l1 j' R
- treenode curlabel = assertlabel(current, labelName, DATATYPE_NUMBER);
8 C" k$ o1 C: x+ z% @ - 4 I: S1 T2 X& J
- if (time()==0) / H; X1 e3 j+ g
- {
' A1 h' T/ b, @5 A5 l0 z - setnodenum(curlabel,batchnumber);
6 ]: f1 e) x# D; ^4 m - return cycletime;
' y( e6 r( A3 `8 m" |8 o2 h - }
6 A# y4 r) w. @0 A& u - else
% k% i& J0 K5 K8 ]' U% x+ F1 [ - {
# _1 s- E. M5 i0 {$ | - if (getnodenum(curlabel)==1)
9 @. x' n- [- _; r, Q - //如果等于0,似乎是正确的,但是会比预期中的批次数量大1.* O/ u# ?$ l! R' V9 ?
- //原因在于只要激发了该触发,就一定会生成一个临时实体。8 J: A3 |& r" l& v+ l i3 t! O
- {9 O& a' ?0 a; G% B/ P* @
- setnodenum(curlabel,batchnumber);
$ v1 L7 E1 Q( x1 U# m - //想要执行的语句一定要放在return前面。7 V: K8 Y* `7 }2 h. o# ?, o, z
- return cycletime;
, A2 R9 Z: m9 {6 {: \; l" s3 Z - }8 t2 C ~, E5 c) D
- else ) ]' Q1 J# l* b3 k
- {
) z9 N- h K' |/ z6 x - inc(curlabel,-1);9 C2 S! _7 K( n1 g
- return 0; 1 H3 f% Y/ f# a6 X5 [

复制代码 以下是flexsim自带代码:- int batchnumber = 5;
3 O9 ~1 b& n' H- s - double cycletime = exponential(0, 10, 0);
" v- R2 X. ^/ T' e$ i" p% t - string labelName = "批次数量";
3 t0 d. Y) x1 L" B6 j8 n# [ - ' T D! A0 B* b& r, o, a
- treenode curlabel = assertlabel(current, labelName, DATATYPE_NUMBER);" y; I4 {3 E0 a# B* E
8 E8 ?8 O5 |1 \; J8 @1 r' [: f- if (time()>0 && getnodenum(curlabel)>1) {
& G; x& V! i) w" t2 p0 c - inc(curlabel,-1);
3 Y0 G" b8 ^6 M( _0 o - return 0;
7 r2 s& e# ]4 h% W - } else { l5 }8 e: h# d" t: m
- setnodenum(curlabel,batchnumber);
. e' O& `6 Y# p' l: ~1 c, T. s8 X! q - return cycletime;3 \- Q! y& B) o' A2 Y
- }
