SINGLE OBJECTIVE FOR AN INTEGER PARTIAL FLEXIBLE OPEN SHOP SCHEDULING PROBLEM USING DEVELOPED ANT COLONY OPTIMIZATION

As an augmentation of the classical mechanical open shop scheduling problem, the Integer partial flexible open shop scheduling problem (IPFOSP) assumes an important role in genuine production systems. In IPFOSP, an operation is permitted to be prepared on in excess of one elective machine. It has been turned out to be an emphatically NP-hard problem. Ant colony optimization (ACO) has been turned out to be a successful approach for managing IFOSP. Since, the key ACO has two essential bothers including low computational efficiency and local ideal. In defect these two brothers, a developed ant colony optimization (DACO) is proposed to propel the make span for IPFOSP. The accompanying perspectives are done on our developed ant colony optimization algorithm: select machine govern problems, instate uniform appropriated mechanism for ants, change pheromone's coordinating mechanism, select hub method, and refresh pheromone's mechanism. The genuine production instance and two plans of well –known benchmark instances are inspected and correlations with some unique approaches conform the viability of the proposed DACO. The results reveal that our proposed DACO can give better arrangement in a sensitive computational time.
