The space-time picture of the process, inherently present in the Lund fragmentation model, is explicitly used. The model is used to check systematic errors in the W mass measurements due to the Bose-Einstein effect. The possibility of direct implementation of the Bose-Einstein effect into string fragmentation is discussed.26 pages, Latex, 17 figures in PS format attachedHigh Energy Physics - Phenomenologytext
