%% Define the workflow
wf = Workflow('SerialWorkflow');
 
% Add activities with exponential service times
A = wf.addActivity('A', Exp.fitMean(1.0));
B = wf.addActivity('B', Exp.fitMean(2.0));
C = wf.addActivity('C', Exp.fitMean(1.5));
 
% Define serial precedence
wf.addPrecedence(Workflow.Serial(A, B, C));
 
%% Convert to phase-type distribution
ph = wf.toPH();
 
%% Display results
