Most published articles in scheduling research are focused in developing models and algorithms to theoreticalproblems having limited applications. The scheduling problem identified in the collaborating company happensto be very different from those know in literature. It involves the scheduling of a large variety of orders withgreater operational complexity. Many of the operations on the products are to be processed unit by unit.However, most products also need to passes through a batch processing facility with apparent complexity toincorporate in a scheduling model. Moreover, products need both machining and assembly operations wherecomponents and sub-assemblies need to pass through many processing stations. Some of the products haveoperations that are outsourced and their semi-finished inventory needs to be sent to other facilities and bereturned for further in-house processing. Machine operators are limited resources. Many of these operators arecross trained and can be assigned to different types of machines. Operators may also tend more than onemachine at a time. Hence their task need to be scheduled in details along the operations. Critical segments ofthe manufacturing facility are operated multiple shift or overtime while the rest are operated only a single shift.These unique combination of problem features makes scheduling very difficult. Hence, the company faces achallenge in running its operations smoothly with minimal work-in-process inventory while at the same timemeeting product delivery dates. A preliminary study was conducted to develop an efficient schedulingtechnique based on Event Scheduling/Time Advance (ESTA) algorithm. The approach proves to be capable ofhandling many of the operational logic of the manufacturing facility and generate schedules for the machinesand the operators, and optimize several performance criteria. This research is a continuation of thisachievement and is aimed at enhancing the developed algorithm to incorporate several details of themanufacturing system. Moreover, a limited study will be conducted for integrating production scheduling withother operational issues such as inventory management and maintenance planning.

调度研究中的大多数发表文章都集中在开发具有有限应用程序的理论问题上的模型和算法上。合作公司中确定的调度问题与文献中的知识大不相同。它涉及与Greater操作复杂性的各种订单的安排。许多产品的许多操作都应按单元进行处理。但是，大多数产品还需要通过调度模型中具有显然复杂性的批处理处理设施。此外，产品需要加工和组装操作以及子组件需要通过许多处理站。一些产品外包和半成品库存的产品需要发送到其他设施，并进行bereturn以进行进一步的内部处理。机器运营商是有限的资源。这些操作员中有许多经过培训，可以分配给不同类型的机器。操作员一次也可能比Onemachine更趋于趋势。因此，他们的任务需要在操作范围内进行详细安排。制造工厂的关键段是多次换班或加班的，而其余的只有单个偏移。这些问题功能的独特组合使调度非常困难。因此，该公司面临着Achallenge的运行，并在同一派遣产品的产品交付日期中以最少的工作库存顺利运行运营。进行了一项初步研究，以根据事件调度/时间提前（ESTA）算法开发有效的调度技术。该方法被证明能够掌握制造工厂的许多操作逻辑，并为机器和操作员生成时间表，并优化多个性能标准。这项研究是这项研究的延续，旨在增强开发的算法，以结合制造系统的几个细节。此外，将进行有限的研究，以将生产计划与其他运营问题（例如库存管理和维护计划）相结合。
