In this paper, production of ${ \rm W}^{ \pm}$ and ${ \rm Z}^{ 0}$ vector bosons in p-p, p-Pb (Pb-p), and Pb-Pb collisions at $\sqrt{ s_{ \rm NN}}=5.02$ TeV is dynamically simulated with a parton and hadron cascade model PACIAE. ALICE data of ${ \rm Z}^{ 0}$ production is found to be reproduced fairly well. A prediction for ${ \rm W}^{ \pm}$ production is given in the same collision systems, at the same energy and at the same energy. An interesting isospin-effect is observed in the sign-change of $\mu^{ \pm}$ charge asymmetry in pp, pn, np, and nn collisions and in minimum bias p-Pb, Pb-p and Pb-Pb collisions at $\sqrt{ s_{ \rm NN}}=5.02$ TeV, respectively.
