Decision variable

SOThe service sequence set of ships arriving in the period
Berthing sequence number of ship i, i ∈ S
SBShip berth allocation set
Berthing serial number of ship i, i ∈ S
SCShip operation quay crane collection
SCiNumber of quay cranes for ship I, i ∈ S
TaiShip I arrival time, i ∈ S
TbiShip I berthing time, i ∈ S
TwiCommencement of ship i, i ∈ S
TuiDeparture time of ship i, i ∈ S
TAverage ship on duty time
If quay crane u is assigned to ship i at time t, the value is 1, otherwise it is 0
Container handling quantity of vessel I
Number of containers handled by quay crane u allocated for vessel I
Xijk{0, 1} is a 0–1 decision variable; when ship I is served in order k on berth J, the value is 1; otherwise, it is zero
