An Adjustment Method for the Customized Trains of the Railway

Algorithm 1

	Step1: Built the alternative set of CT
	Step1.1: Determine the number of CTs and the number and the ratio of sleeping train units and seat train units of each train according to equation (1);
	Step1.2: Determine the stop plan of the CT according to equation (2);
	Step1.3: Determine the original departure time period and the passenger demand of the CTs based on the questionnaires.
	Step1.4: The alternatives set of CTs is built BL = {i ∈ [1, nc]};
	Step2: The function of CTs selection
(1)	The CTs operation scheme set SL = {f ∈ [1, ns]};
(2)	Z = 0; flag = 0; A = f;
(3)	For f = 1 to nsdo
(4)	For i = 1 to ncdo
(5)	The can be obtained by the questionnaires;
(6)	For s = 1 to m do
(7)	If equations (6)–(12) cannot be satisfied then
(8)	flag = 1;
(9)	Z1 = Z1 + Equation (5);
(10)	End If
(11)	End For
(12)	End For
(13)	If flag == 0
(14)	Z2 = function2 (f);
(15)	End If
(16)	If Z2 ! = Null then
(17)	Z′ = Z1 − Z2;
(18)	If Z′ > Z then
(19)	Z = Z′; A = f;
(20)	End If
(21)	End If
(22)	End For
	Step3: The function of the train adjustment Z2 = function2 (A)
(1)	Nadj = number of delayed trains, including the CTs.
(2)	For i = 1 to Nadj do
(3)	For s = 1 to m do
(4)	If then
(5)	Totaladj = 100000;
(6)	For u = 1 to 3 do
(7)	If the constraints of the strategy u is satisfied then
(8)	If Tu < TotaladjThen
(9)	Totaladj = Tu;
(10)	;
(11)	End If
(12)	End if
(13)	End for
(14)	End if
(15)	End for
(16)	If equations (14)–(16) cannot be satisfied then
(17)	A = Null;
(18)	Break;
(19)	End if
(20)	End for
(21)	Return Z2 = Equation (13);
