Production planning and control is the single decision area in a company's manufacturing strategy that most directly impacts the manufacturing system's ability to achieve operational mix flexibility. With product variety being a fundamental industrial feature in modern manufacturing environments, mix flexibility is a key objective for manufacturing companies to meet customer requirements, with regard to the correct mix of products, at the required volumes and at the required timing. Sequencing is perhaps the single most important production planning routine for mix flexibility achievement on a shared manufacturing resource. However, unlike discrete manufacturing, there are limited prescribed techniques for sequencing routines in process manufacturing. This paper explores sequencing via the product wheel technique through its application in two case studies.
