A batch of jobs can be processed simultaneously in some available processing time interval as long as the total size of these jobs doesn\u2019t exceed the machine capacity. The processing time of a job batch is the largest processing time of the jobs contained in this batch and the production progress is non-resumable. Our objective is to minimize the last maintenance completion time. For the case where jobs have unit processing times, we show the problem is strongly NP-hard and present a [Formula: see text]-approximation algorithm. For the case where jobs have unit sizes, we show the problem is also strongly NP-hard and provide a [Formula: see text]-approximation algorithm. Finally, we study the general case where jobs have non-identical processing times and sizes and propose a [Formula: see text]-approximation algorithm. <\/jats:p>","DOI":"10.1142\/s0129054125460025","type":"journal-article","created":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T02:57:36Z","timestamp":1745377056000},"page":"827-840","source":"Crossref","is-referenced-by-count":0,"title":["Non-Resumable Scheduling on a Single Bounded Parallel-Batch Machine with Flexible Maintenance"],"prefix":"10.1142","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4644-7225","authenticated-orcid":false,"given":"Jing","family":"Fan","sequence":"first","affiliation":[{"name":"School of Mathematics, Physics and Statistics, Shanghai Polytechnic University, Shanghai 201209, P.
