This paper presents a GERT method based on fuzzy theory for solving fuzzy project scheduling of sugarcane production (preserve operations, harvesting and rationing) in Khuzestan province of Iran. In this method, activity duration time and loops, repetition number, and output activities from nodes of network belong to a fuzzy set. First, an analytical approach was proposed to simplify the structure of network. Then, GERT network computations were done based on evaluating nodes. Process outputs were scheduled network and project fuzzy completion time. These outputs were fuzzy numbers and can be analyzed by α- cut. Results prove that the method of using fuzzy numbers and fuzzy relation in project scheduling is a powerful tool to estimate time for agricultural... |

A milk marketing cooperative (MMC) was created by Florida dairy farmers to link the primary supply of fluid milk with the derived demand of processors in the vertical market. For any given milk supply, the revenue or return to farmers per unit of milk is the average milk price received by the MMC minus the MMC’s transfer cost. An important task for the MMC is to operate the fluid milk hauling system that optimizes the MMC’s milk transfer cost (routing and scheduling cost) subject to farm and plant schedules. The objective of this study is to determine if it is economically feasible to implement a more efficient routing and scheduling of farm-to-plant milk collection by the MMC. |
