The Impact Of Decision-Making On Production Activities
This study used control theory to model sales planning, long-term planning, rolling planning, materials planning, short-term planning, manufacturing, delivery and sale, and investigated how factors required for decision-making in each planning phase impact the overall planning through simulations. To find the degree of impact each phase has on the overall plan, the investigation method involved used each factor of planning as a variable in the control model. And the differences in results between impacts, when simulated by individually making them into constants and when simulated as a variable, were calculated. The findings of this study are considered to contribute to enhance corporate competitiveness by enabling appropriate planning, production equipment and technologies for production activities which actually produce profit.
