The Combination of Management and Customer Comments in Determining Product Mix Based on Revised Fuzzy Theory of Constraints

Activities such as preparing materials, production planning and inventory control and supply of goods are considered as the key areas of supply chain are management and control. It is possible to identify how many and when each product must be produced by planning. Manufacturers can prioritize each product based on the capacity of the lines, the human resources and etc. Moreover, customers might consider other priority for each product. Accordingly, it is important to determine the amount of production for each product by drawing on management and customer comments. On the other hand, due to the indeterminate nature of data in the real world, the fuzzy logic approach is used for production capacity, processing time and profit. In this paper using the revised fuzzy theory of constraints and priorities of customer, a mixed production is determined and it keeps a balance between producer and customer priorities. The proposed algorithm has been studied using numerical example. The results show the effectiveness of this approach in real-world.
