项目摘要

In accordance with our research proposal, we have successfully generated an array of problems related to seru formation and loading by varying different input elements. These problem sets were used to analyze computational complexities, identifying whether each problem was NP-hard or polynomial and determining its convexity. As anticipated, the majority of the seru problems were NP-hard and non-convex. For the NP-hard problems, we found achievable approximation ratios and subsequently developed polynomial algorithms to obtain solutions with optimal approximation ratios. For non-convex problems, we designed algorithms that can converge to local optimal results.The process of constructing mathematical models necessitated the identification of key elements relevant to smart manufacturing. These elements were derived from various sources, such as industrial conferences like the Annual Conference of Japan Institute of Industrial Engineering, studying industrial cases in Japanese and English journals and magazines, and engaging in discussions with our MBA students who have direct factory experience.In conclusion, the work undertaken over the past year represents significant strides in analyzing and modeling seru formation and loading problems. We've adopted a systematic approach that leverages a broad array of input variables to generate detailed mathematical models. We remain committed to the ongoing exploration of this subject, and we look forward to the breakthroughs that the coming year will bring.

根据我们的研究建议，我们已经成功地产生了一系列的问题，通过不同的输入元素的seru形成和加载。这些问题集被用来分析计算复杂性，确定每个问题是NP困难的还是多项式的，并确定其凸性。正如预期的那样，大多数seru问题是NP难和非凸的。对于NP难问题，我们找到了可实现的近似比，并随后开发了多项式算法，以获得最佳近似比的解决方案。对于非凸问题，我们设计了能够收敛到局部最优解的算法，在建立数学模型的过程中，需要识别与智能制造相关的关键要素。这些要素来自于日本工业工学研究所年会等产业会议、在日、英杂志上研究产业案例、与有工厂直接经验的MBA学生进行讨论等各种来源。总之，一年来的工作在浆液形成和装填问题的分析和模型化方面取得了重大进展。我们采用了一种系统化的方法，利用广泛的输入变量来生成详细的数学模型。我们仍然致力于继续探索这一问题，并期待着来年取得突破。
