Purpose This paper aims to propose a capacity assessment approach for production with uncertainty, focusing on single batch machine interval grey processing time. Design/methodology/approach Based the number and its mathematical operations, uncertain time is defined as research object. The times generation methods are then developed, which rely specific definitions historical data. A tailored this mode subsequently proposed, validity demonstrated through multiple real-world cases from one aerospace composite material manufacturer. Findings proposed provides reliable results various types of tasks. For tasks small jobs or significant variations in job sizes, can be obtained first stage, known model assessment. remaining tasks, achieved second heuristic Research limitations/implications In paper, validated based production. To enhance applicability more actual scenarios, needs extend modes. algorithm have certain limitations need further designed suit other Originality/value novel And it helps promote application system theory management.
