| dc.description.abstract | The objective of this study is to maximize the production capacity of national defense weapon systems by preserving knowledge and experience and achieving fairness in workload assignment. The production of national defense weapon systems involves integrating existing resources in the production and preparation process. There is a limited supply of explosive-only factories, warehouses, and personnel with explosive expertise, and the retirement of experienced senior personnel poses a challenge to production capacity. General defense weapon systems can be classified into serial ammunition (e.g., missiles) and batch ammunition (e.g., rockets, warheads, fuzes, etc.). Regardless of the ammunition type, a weapon system comprises three components: fuze, warhead, and propellent. The production process stretches across three major domains: machining, chemical explosives, and electronic circuits. The production is completed under a quality control system and reliability design.
The study focuses on the production of traditional weaponry, and the processes and working hours are considered constant in subsequent analysis. The study is conducted with the concept of a production line in mind, where the use of manpower is optimal, and new recruits are hired to inherit the skills and knowledge from seasoned experts. The study aims to achieve fairness in workload assignment, taking into account the daily number of people on duty and the difference between roles. To achieve this, the study constructs a model through mathematical 0-1 integer programming and programming constraints. Computer software such as LINGO 18.0 and EXECL are used for data output, and the study explores optimal shift scheduling and performs sensitivity analysis based on variations in staff capacity or the number of working days. The data used in the analysis may serve as key indicators for production line rearrangements and provide realistic considerations to decision makers. Ultimately, the findings of this study may increase production capacity and readiness of the nation′s defense weapon systems. | en_US |
