ABSTRACT

STANDARDIZATION AND FLEXIBLE WORK CELLS FOR HIGH VARIETY, LOW VOLUME MANUFACTURING

This thesis studies the opportunities for the application of lean manufacturing tools in a high mix, low-volume traditional manufacturing factory floor setting. A job shop is a manufacturing system well-known for its operational complexity due to the conditions under which it operates, such as instability of order volumes, product mix, product routings, customer bases, and etc.

A fundamental approach to improve the performance and efficiency of job shops has been to transform the Functional Layout that they traditionally use into a Cellular Layout. Cellular Layouts provide shorter production lead times, lower WIP inventory levels, simpler scheduling, and better control of product quality. However, Cellular Layouts have major disadvantages such as low machine utilization, high cost of cell reconfiguration when demand or product mix change, and high risk of disruption to production due to machine breakdowns and operator absenteeism. These disadvantages are especially harmful for job shops because they operate in a high-mix low-volume (HMLV) environment.

Consequently operations are not standardized and batch and queue operational strategies are employed. However, closer examination reveals that these operations largely consist of a small number of elemental machine functions that are exercised in various combinations.

Value stream mapping and other associated analytical tools are used to explore the opportunities to streamline the flow of products on the floor with a focus on reducing inventory and improving quality.

To complement the analysis, this thesis also examines the impact of improved floor employee involvement. It considers several aspects including the increased empowerment of the direct labor staff, stronger team participation, and a greater focus on solutions specifically tailored to the particular area. Based on the results of the work, the recommendation is in increased focus on developing team skills and empowerment, specifically within the direct labor staff. This approach is demonstrated using an industrial case study.
