Abstract
Production Planning and Control (PPC) is concerned with planning and controlling all
aspects of manufacturing, including managing materials, scheduling machines and
people, and coordinating suppliers' and key customers. Providing the capability to
satisfy current and future demand is a fundamental responsibility of operations
management. The important characteristic of PPC is concerned with to detennine
capacity levels over short and medium tenns in aggregated tenns. This research focuses
on developing a Machine Capacity Model for single unit machine capacity measure.
The model development consists of three main development phases constructed using
analytical mathematical equation derived from operational parameters and translated
into a common computer programming presented as spreadsheet template. The First

planning, The model development does not require any extra cost to purchase any
expensive software or facility, Computational approaches of the model have the
requisite flexibility to yield solutions under different circumstances, Therefore these
advantages increase the industrial acceptance and practical level.
