Work Schedule Optimization System for Assembly Line Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assignment and rotation of workers on assembly lines often result in sub-optimal assignments due to the vast number of possible combinations, leading to increased workplace injuries, reduced worker satisfaction, and decreased product quality, as supervisors struggle to account for various variables like training, experience, and ergonomic impacts.
Innovation Solution
A system and method for generating optimized work schedules based on identified parameters such as ergonomic impact, training, and experience, using a processor to receive and process information about workers and tasks, and outputting schedules that prioritize selected optimization parameters to improve worker satisfaction and product quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a supervisor manually assigns workers to positions, then the assignment process is simple and direct, but the number of possible combinations becomes too large to evaluate, resulting in sub-optimal assignments
Solution Approach 1:
The patent replaces the mechanical manual assignment process with an automated computer-based system that uses algorithms to evaluate all possible worker-position-rotation combinations. The system receives variables including worker skills, position requirements, and rotation constraints, then automatically generates optimized assignments that would be impossible for a human supervisor to evaluate manually among 6.4×10^15 combinations.
Solution Approach 2:
The system changes the approach from evaluating assignments based on limited human judgment to systematically evaluating all combinations based on multiple quantified parameters including worker training levels, experience, ergonomic impacts on different body parts, position requirements, and rotation schedules. This parameter-based evaluation enables optimal assignment selection.
2Productivity
If all possible worker-position-rotation combinations are evaluated to find the optimal assignment, then assignment optimality improves, but the computational complexity and time required increases dramatically
Solution Approach 1:
The patent segments the complex assignment problem into manageable components by receiving separate variables for worker characteristics, position requirements, rotation constraints, and ergonomic parameters. The system processes these segmented inputs through modular evaluation steps, ultimately combining them to select the optimal assignment from all possible combinations.
Solution Approach 2:
The computer-based system acts as an intermediary between the vast space of possible assignments and the final optimal selection. It receives multiple input variables, processes them through systematic evaluation, and produces the optimized assignment schedule, mediating the complexity by automating the evaluation process that would otherwise be intractable.
3Reliability
If worker assignments optimize for multiple variables including ergonomic impact, training, and experience, then worker satisfaction and product quality improve, but the number of variables to account for increases
Solution Approach 1:
The patent creates a universal system that simultaneously evaluates multiple variables including worker training levels, experience, ergonomic impacts on various body parts, position requirements, and rotation constraints. The single automated system performs all these evaluations concurrently and integrates them to produce optimized assignments that balance all competing factors.
Solution Approach 2:
The system transforms multiple qualitative variables (ergonomic impact, training quality, experience level) into quantifiable parameters that can be systematically evaluated. By converting these diverse factors into measurable parameters with assigned weights, the system can objectively compare different assignment options across all variables simultaneously.

AI summary
Systems and methods for generating work schedules are provided. Work schedules are generated based on an identification of work periods and tasks and information related to the workers. A work schedule is produced based on a selected optimization parameter. The optimization parameter can be any type of parameter related to the tasks and workers. The optimization parameter can be ergonomic impact, level of training, experience level or the like. The systems and methods can also receive assigned tasks for one or more of the workers, and generate a schedule incorporating the assignments.
