Dears, I am a postgraduate student and a new user to spyder software too.
I am using this program by python language programming and i pass a long way to learn python and spyder to able to insert my code. But I faced some errors and I tried to solve it and i succeed but some of them I tried but I don't know what's the problem. So, I am glad to have this huge community to ask respected experts like you and I wish to support me to solve this issue since I don't have any guide know this software in my college the error in the equation #2 *for b in range(1,3):* * #create constraints* *m.addConstr(quicksum(x[b,j,t] <=1 for j in J for t in range(r[b],(d[b]-p[b]+1))),name="block_allocation") #eqution 2 * *the error that showed me up is * *>>> runfile('C:/Users/Ahmed/AppData/Roaming/Microsoft/Windows/Network Shortcuts/operating_roomintegrated.py', wdir='C:/Users/Ahmed/AppData/Roaming/Microsoft/Windows/Network Shortcuts')* *Traceback (most recent call last):* * File "<stdin>", line 1, in <module>* * File "C:\ProgramData\Anaconda2\lib\site-packages\spyder\utils\site\sitecustomize.py", line 866, in runfile* * execfile(filename, namespace)* * File "C:\ProgramData\Anaconda2\lib\site-packages\spyder\utils\site\sitecustomize.py", line 87, in execfile* * exec(compile(scripttext, filename, 'exec'), glob, loc)* * File "C:/Users/Ahmed/AppData/Roaming/Microsoft/Windows/Network Shortcuts/operating_roomintegrated.py", line 31* * m.addConstr(quicksum(x[b,j,t] <=1 for j in J for t in range(r[b],(d[b]-p[b]+1))),name="block_allocation") #eqution 2 * * ^* *IndentationError: expected an indented block* *>>> * this my code: # -*- coding: utf-8 -*- """ Created on Sun Apr 02 19:36:07 2017 @author: Ahmed """ from gurobipy import* try: m = Model('operating_room') #Data b= [1,2,3] n= [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25] j= [1,2,3,4,5,6,7,8,9,10,11,12,13] t=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32] W=0.5 p[b]= 15 h[b]= [1,2,3] m.update() #create variables X[j] =m.addVar(vtype=GRB.BINARY, name="X[j]") Y[n] =m.addVar(vtype=GRB.BINARY, name="Y[n]") x[b,j,t] = m.addVar(vtype=GRB.BINARY,name="x[b,j,t]") y[n,b] = m.addVar(vtype=GRB.BINARY,name="y[n,b]") m.update() #set objective m.setObjective(quicksum(X[j] for j in J )+ W*(quicksum(Y[n] for n in N)),GRB.MINIMIZE) #eqution 1 * for b in range(1,3):* * #create constraints* * m.addConstr(quicksum(x[b,j,t] <=1 for j in J for t in range(r[b],(d[b]-p[b]+1))),name="block_allocation") #eqution 2 * #equation 3 for b in range(1,b): for j in J: for t in T: m.addConstr(x[b,j,t] <= X[j] ,name="allocation_to_open_OR") #equation 4 for j in J: for t in T: m.addConstr(quicksum(x[b,j,l]<=1 for b in range(1:B) for l in range(t-p[b]+1:t)),name="overlaping_blocks") #equation 5 for b in range(1:B): m.addConstr(quicksum(y[n,b]=h[b],for n in N),name="surgical_nurse_demand") #equation 6 for n in N: for b in range(1:B): m.addConstr(y[n,b]<=Y[n],name="used_surgical_nurses") #equation 7 for b,b1 in range(1:B): for n in N: for t in T: m.addConstr(quicksum(x[b,j,l],for j in J for l in range(t-p[b]+1:t)) + quicksum(x[b1,j,l] <= (3-y[n,b]-y[n,b1]),for j in J for l in range(t-p[b1]+1:t)),name="link to scheduling") #equation 8 for b in range(1:B): for j in J: for t in T: m.addConstr(x[b,j,t] in {0,1},name="integerity_1") #equation 9 for j in J: m.addConstr(X[j] in {0,1},name="integerity_2") #equation 10 for b in range(1:B): for n in N: m.addConstr(y[n,b] in {0,1},name="integerity_3") #equation 11 for n in N: m.addConstr(Y[n] in {0,1},name="integerity_4") #equation 12 for n in N: for b,b1 in range(1:B): for o[b]!= o[b1]: m.addConstr(y[n,b]+y[n,b1]<=1,name="assignment_of_nurses_in_different_OR") #equation 13 m.addConstr(max(s[b],s[b1])<min(s[b]+p[b],s[b1]+p[b1]),name="prevent_overlapping_in_diff_OR") m.optimize() -- You received this message because you are subscribed to the Google Groups "spyder" group.
