| Abstract: | Through a series of research on 10 Japanese ships since 1961, it was found that the relationship between number of crew and the resulting structural change of work on board ship can be formulated by a linear regression. Some of the major findings that are obtained from this new method are summarized as follows. As the number of crew decreases, the proportion of work for operating the ship (manoeuving and controlling work) increases, while the proportion of work which is not directly related to the operation decreases. This structural change can be attributed to work simplification resulting from four types of the transformation of work: (a) The replacement of man'al work by putting machines on board. (b) The transformation of work on board into work done by machines on shore. (c) The transfer of work previously done on board to the shore. (d) The transformation of work within a ship. |
