jobshopproductie

Jobshopproductie, also known as job shop production, is a manufacturing approach characterized by high variety and low volumes, where many different products are produced in a facility with a functional (process-focused) layout. In a job shop, general-purpose machines and skilled workers handle a wide range of operations, and each customer order follows a unique routing through the shop. This setup prioritizes flexibility and the ability to accommodate frequent design changes and custom specifications, often at the expense of longer lead times and higher unit costs.

Key features include a high mix of products, long setup times, and routing-dependent workflows. Planning and scheduling are complex and typically driven by incoming orders rather than a fixed production schedule. Work orders, prioritization rules, and dispatch systems determine the sequence of jobs. Equipment is organized by function (e.g., milling, turning, grinding), and workers often cross-train to operate multiple machines.

Advantages of job shop production include strong responsiveness to customer specifications, the capability to handle custom or small-batch products, and lower initial capital needs for specialized equipment. Disadvantages include higher work-in-process inventory, longer lead times, variable throughput, and challenging capacity planning and scheduling. Utilization can be uneven, and cost per unit tends to be higher for small lots.

Industries that commonly use job shop production include machine shops, tool and die shops, contract manufacturers, and certain aerospace or automotive prototyping environments. Key performance metrics are lead time, on-time delivery, throughput, and overall equipment utilization. Related concepts include job shop scheduling problems and process-focused manufacturing, which contrast with flow or mass production approaches.
