Abstract
For the past few decades, the production schedule has been the focal area for researchers under different production types and respective strategies being implemented on. Among the previous researches, the partial flexible job shop scheduling problem with the concept of the production strategy implemented on hasn’t brought to the academic research as well as practical based research development areas. Based on the reviewed articles and studies, it has been identified that there exists certain gaps on the production scheduling of a partial flexible job shop production floor type and the strategy implemented.
The need for this concept is to clearly define methods using the production scheduling to indicate on how to manage the natural constraint conflict taking place on this very kind production floor type. In meantime, support the implemented strategy to improve the throughput and other performance parameters such as capacity to accept new orders, WIP accumulation percentage and number of tardy job orders.
Thus, this paper will be proposing production scheduling using dispatching rules integrated in simulation tool. The throughput improvement is achieved as a result of to the factors of improved work-in-process (“WIP”) accumulation % and tardy number of job orders. The study is conducted based on clear understanding of the existing production scheduling and developing consistent production scheduling policy, strategy and methods using the above mentioned tool in representing the operating system and respective scheduling model. The overall aim of the study is to propose suitable production scheduling using dispatching rules to concisely developed for the production nature under the study; and simulation tool to exhaustively representing the production floor. As a result improve the number of tardy jobs as well as other neglected performance metrics: capacity to accept new orders, WIP accumulation percentage and throughput of the production floor.
