Generation method for each model input

Model inputGeneration method
JEnumeration ranging from 1 to (1 + E) for (P, E, N) in the parameter RC
REnumeration ranging from 1 to (P + EN) for (P, E, N) in parameter RC
rijFor (P, E, N) in the parameter RC: first P resources have rij=1. Thereafter, every consecutive block e in 2…E of N resources has rie=1. All remaining ub=0
TEnumeration ranging from 1 to (TPS × 3 days × 2 shifts per day). Consecutive shifts are designated as consecutive blocks of TPS tasks
Djk(Uniform random value in PA) × (total available units of resource j)
dijkSR for i=1, j>1 on all tasks k and 0 otherwise
SjkUniform random value in SPR
yik0 in all initial problem versions, xik for corresponding initial problem in each updated problem
mik+0 in all initial problem versions, OTP in each updated problem
mik0 in all initial problem versions, AFP in each updated problem
AikLet V=uniform random value in PA. Then for each resource i (V × total number of tasks) elements are randomly selected from T and Aik=1 for each element k. All other Aik=0
uikk'For each resource i, uikk'=1 for all tasks in either the same shift or the shift immediately preceding or following, 0 otherwise
LjkDjk
BikBPA
cjkUniform random value in TCR if not going to dummy task, 0 otherwise (applies to transportation-based model only)
