Abstract
This paper discusses teh length of growth term and profitability of Epiphyllum russellianum Hook selected, as in Part I, from many kinds of potted flowers grown under glass, and grown under the same conditions as in Part I, with the production planning period limited.In this case, only price ratio is dealt with as an uncertain factor.Three realistic production plans are selected from innumerable possible plans.Through comparison of these selected plans, a space of price ratio that was considered effective for selecting the plan which contains the uncertain factor was derived.The author proposes this space as an effective answer to the decision problem that contains the uncertain factor and problems raised by this paper.
