Thank you Darby for quick reply.
it work perfect. I add-on some expression in it.
Thank you.
rand=thisComp.layer("Control").effect("Position Random Seed")("Slider");
delay = thisComp.layer("Control").effect("Delay")("Slider")
min = thisComp.layer("Control").effect("Min Position")("Slider");
max = thisComp.layer("Control").effect("Max Position")("Slider");
seedRandom(rand, true);
x = random(min, max);
y = random(min, max);
z = random(min, max);
d = delay*thisComp.frameDuration*(index - 1);
thisComp.layer(1).position.valueAtTime(time - d)+[x,y,z];
